change: add setup stamp

_cmd_update_impl (monolith ~1350 lines) is gone. The update flow is now:

Phase 1 (_cmd_update_pull_new_version):
  - concurrent guard, backup, git pull / ZIP download+extract
  - stash handling, syntax guard, rollback, bytecode clear

Phase 2 (_cmd_update_post_pull):
  - pip install (managed-uv), node deps, web UI, desktop rebuild
  - skills sync, config migration, gateway restart, cleanup

Between phases, _reexec_for_post_pull replaces the process:
  - POSIX: os.execvp (true exec, same PID, fresh sys.modules)
  - Windows: subprocess.run relay (parent stays alive so bootstrap
    installer's child.wait() sees the real exit code)

Hidden --post-pull flag routes directly to phase 2.
--pre-update-snapshot carries snapshot ID across exec boundary.

Pip self-update is removed entirely. pip/uv/pipx installs now error
with recommended_update_command guidance, same as managed installs.

Also allow uv to come from termux.

Test updates:
  - _inline_post_pull autouse fixture in test_cmd_update,
    test_update_autostash, test_update_concurrent_quarantine
    (patches _reexec_for_post_pull to call _cmd_update_post_pull
    in-process, preventing os.execvp from nuking pytest)
  - test_uv_tool_update: removed _cmd_update_pip tests (function
    deleted), kept is_uv_tool_install + recommendation helpers
  - test_update_zip_symlink_reject: renamed imports to match
    _update_files_via_zip (now a thin delegation wrapper)

 **Never give up on the right solution.**
 
-## What Hermes Is
-
-Hermes is a personal AI agent that runs the same agent core across a CLI, a
-messaging gateway (Telegram, Discord, Slack, and ~20 other platforms), a TUI,
-and an Electron desktop app. It learns across sessions (memory + skills),
-delegates to subagents, runs scheduled jobs, and drives a real terminal and
-browser. It is extended primarily through **plugins and skills**, not by
-growing the core.
-
-Two properties shape almost every design decision and are the lens for
-reviewing any change:
-
-- **Per-conversation prompt caching is sacred.** A long-lived conversation
-  reuses a cached prefix every turn. Anything that mutates past context,
-  swaps toolsets, or rebuilds the system prompt mid-conversation invalidates
-  that cache and multiplies the user's cost. We do not do it (the one
-  exception is context compression).
-- **The core is a narrow waist; capability lives at the edges.** Every model
-  tool we add is sent on every API call, so the bar for a new *core* tool is
-  high. Most new capability should arrive as a CLI command + skill, a
-  service-gated tool, or a plugin — not as core surface.
-
-## Contribution Rubric — What We Want / What We Don't
-
-This is the project's intent layer. Use it two ways:
-
-1. **For humans and for your own work** — what gets merged and what gets
-   rejected, so a contribution aims at the target.
-2. **For automated review (the triage sweeper)** — guidance on when a PR is
-   safe to close on the three allowed reasons (`implemented_on_main`,
-   `cannot_reproduce`, `incoherent`) and, just as important, **when NOT to
-   close** one. Taste-based "we don't want this / out of scope" closes are NOT
-   an automated decision — those stay with a human maintainer. The sweeper's
-   job here is to recognize design intent and *avoid wrongly closing a
-   legitimate contribution*, not to make the won't-implement call itself.
-
-Read the balance right: Hermes ships a **lot** — most merges are bug fixes to
-real reported behavior, and the product surface (platforms, channels,
-providers, models, desktop/TUI features) expands aggressively and on purpose.
-The restraint below is aimed squarely at the **core agent + the model tool
-schema**, the one place where every addition is paid for on every API call.
-"Smallest footprint" governs *how a capability is wired into the core*, NOT
-whether the product is allowed to grow. We are expansive at the edges and
-conservative at the waist.
-
-### What we want
-
-- **Fix real bugs, well.** The bulk of what lands is `fix(...)` against an
-  actual reported symptom. A good fix reproduces the symptom on current
-  `main`, points to the exact line where it manifests, and fixes the whole bug
-  class — sibling call paths included — not just the one site the reporter hit.
-- **Expand reach at the edges.** New platform adapters, channels, providers,
-  models, and desktop/TUI/dashboard features are welcome and land routinely,
-  including large ones (a new messaging channel, a session-cap feature, a
-  Windows PTY bridge). Breadth in the product is a goal, not a footprint
-  concern — as long as it integrates with the existing setup/config UX
-  (`hermes tools`, `hermes setup`, auto-install) rather than bolting on a raw
-  env var.
-- **Refactor god-files into clean modules.** Extracting a multi-thousand-line
-  cluster out of `cli.py` / `run_agent.py` / `gateway/run.py` into a focused
-  mixin or module is wanted work, even when the diff is huge and mechanical
-  (large `+N/-N` refactors merge regularly). The "every line traces to the
-  request" test applies to *feature* PRs; a declared refactor's request IS the
-  extraction.
-- **Keep the core narrow.** New *model tools* are the expensive exception —
-  every tool ships on every API call. Prefer, in order: extend existing code →
-  CLI command + skill → service-gated tool (`check_fn`) → plugin → MCP server
-  in the catalog → new core tool (last resort). See "The Footprint Ladder."
-- **Extend, don't duplicate.** Before adding a module/manager/hook, check
-  whether existing infrastructure already covers the use case. When several PRs
-  integrate the same *category*, design one shared interface instead of merging
-  them one at a time (see the ABC + orchestrator note under the Footprint
-  Ladder).
-- **Behavior contracts over snapshots.** Tests should assert how two pieces of
-  data must relate (invariants), not freeze a current value (model lists,
-  config version literals, enumeration counts). See "Don't write
-  change-detector tests."
-- **E2E validation, not just green unit mocks.** For anything touching
-  resolution chains, config propagation, security boundaries, remote
-  backends, or file/network I/O, exercise the real path with real imports
-  against a temp `HERMES_HOME`. Mocks hide integration bugs.
-- **Cache-, alternation-, and invariant-safe.** Preserve prompt caching, strict
-  message role alternation (never two same-role messages in a row; never a
-  synthetic user message injected mid-loop), and a system prompt that is
-  byte-stable for the life of a conversation.
-- **Contributor credit preserved.** Salvage external work by cherry-picking
-  (rebase-merge) so authorship survives in git history; don't reimplement from
-  scratch when you can build on top.
-
-### What we don't want (rejected even when well-built)
-
-- **Speculative infrastructure.** Hooks, callbacks, or extension points with no
-  concrete consumer. Adding a hook is easy; removing one after plugins depend
-  on it is hard. A hook is NOT speculative if a contributor has a real, stated
-  use case — even if the consumer ships separately.
-- **New `HERMES_*` env vars for non-secret config.** `.env` is for secrets
-  only (API keys, tokens, passwords). All behavioral settings — timeouts,
-  thresholds, feature flags, display prefs — go in `config.yaml`. Bridge to an
-  internal env var if the mechanism needs one, but user-facing docs point to
-  `config.yaml`. Reject PRs that tell users to "set X in your .env" unless X
-  is a credential.
-- **A new core tool when terminal + file already do the job, or when a skill
-  would.** If the only barrier is file visibility on a remote backend, fix the
-  mount, not the toolset.
-- **Lazy-reading escape hatches on instructional tools.** No `offset`/`limit`
-  pagination on tools that load content the agent must read fully (skills,
-  prompts, playbooks). Models will read page 1 and skip the rest.
-- **"Fixes" that destroy the feature they secure.** A mitigation that kills the
-  feature's purpose is the wrong mitigation. Read the original commit's intent
-  (`git log -p -S`) before restricting behavior; find a fix that preserves the
-  feature.
-- **Outbound telemetry / usage attribution without opt-in gating.** No new
-  analytics, third-party identifier tagging, or attribution tags until a
-  generic user-facing opt-in (config gate + setup prompt + `hermes tools`
-  toggle) exists. Park behind a label, do not merge.
-- **Change-detector tests, cache-breaking mid-conversation, dead code wired in
-  without E2E proof, and plugins that touch core files.** Plugins live in their
-  own directory and work within the ABCs/hooks we provide; if a plugin needs
-  more, widen the generic plugin surface, don't special-case it in core.
-- **Third-party products / other people's projects integrated into the core
-  tree.** Observability backends, vendor SaaS integrations, analytics dashboards,
-  and similar "someone else's product" plugins do NOT land under `plugins/` in
-  this repo. They place an ongoing maintenance burden on us to keep them working
-  against a fast-moving core, for a backend we don't own. Ship them as a
-  **standalone plugin repo** users install into `~/.hermes/plugins/` (or via a
-  pip entry point), and promote them in the Nous Research Discord
-  (`#plugins-skills-and-skins`). This is a coupling-and-maintenance decision, not
-  a quality bar — the plugin can be excellent and still be a close. PRs that add
-  such a directory to the tree are closed with a pointer to publish it as its own
-  repo.
-
-### Before you call it a bug — verify the premise (and when NOT to close)
-
-The most common reason a well-written PR gets closed is not code quality — it
-is that the change is built on a **wrong premise**, or it treats an
-**intentional design as a gap**. These patterns cut both ways: they tell a
-human reviewer what to scrutinize, and they tell the automated sweeper when a
-PR is NOT safe to close as `implemented_on_main` / `cannot_reproduce` (when in
-doubt, leave it open for a human). They are distilled from real closes.
-
-- **"Intentional design, not a gap."** A limitation that looks like an
-  oversight is often deliberate. Before "fixing" a missing link or a
-  restriction, ask whether the isolation IS the design. Example: profiles are
-  independent islands on purpose — a PR adding live config inheritance from the
-  default profile was closed because coupling profiles together is exactly what
-  the design prevents (the copy-at-creation `--clone` path already covers the
-  legitimate "start from my default" case). Read the original commit's intent
-  (`git log -p -S "<symbol>"`) before assuming something is unfinished.
-- **"The premise doesn't hold against how X actually works."** A PR's
-  justification frequently rests on a wrong mental model of an existing
-  mechanism. Trace the real code/runtime before accepting the rationale. Two
-  real closes: a rate-limit "re-probe during cooldown" PR (the breaker only
-  trips on a *confirmed-empty* account bucket, so re-probing just hammers a
-  bucket we've already proven empty); a usage-accumulation fix whose new branch
-  **never executes at runtime** because an earlier guard already popped the
-  state it depended on. If you can't point to the exact line where the bug
-  manifests AND show the fix changes that line's behavior, you haven't verified
-  the premise.
-- **"This fix was wrong — the absence/omission was deliberate."** Adding the
-  obvious-looking missing piece can break things the omission was protecting.
-  Example: restoring "missing" `__init__.py` files made a test tree importable
-  as a dotted package that shadowed the real plugin, deleting its `register()`
-  at import time. The absence was load-bearing.
-- **"Overreached / resurrected an approach we'd moved past."** Scope creep that
-  supersedes an agreed-on base, or revives a direction the maintainers
-  deliberately closed, gets rejected even when the code works. Keep the change
-  to the narrow piece that was actually agreed; offer the rest as a focused
-  follow-up.
-
-The throughline: **verify the claim AND the intent against the codebase before
-writing or merging a fix.** A confirmed reproduction on current `main` plus a
-line-level account of where the fix acts beats a plausible-sounding rationale
-every time. When in doubt about intent, it is cheaper to ask than to ship a
-fix that fights the design.
-
-### The Footprint Ladder (new capability decision)
-
-Each rung adds more permanent surface than the one above. Choose the highest
-(least-footprint) rung that correctly solves the problem:
-
-1. **Extend existing code** — the capability is a variation of something that
-   already exists. Zero new surface.
-2. **CLI command + skill** — manages config/state/infra expressible as shell
-   commands. The agent runs `hermes <subcommand>` guided by a skill. Zero
-   model-tool footprint. Default choice for subscriptions, scheduled tasks,
-   service setup. Examples: `hermes webhook`, `hermes cron`, `hermes tools`.
-3. **Service-gated tool (`check_fn`)** — needs structured params/returns AND
-   only appears when a prerequisite is configured. Zero footprint otherwise.
-   Examples: Home Assistant tools (gated on token), memory-provider tools.
-4. **Plugin** — third-party/niche/user-specific capability that doesn't ship in
-   core. Lives in `~/.hermes/plugins/` or a pip package, discovered at runtime.
-5. **MCP server (in the catalog)** — if the capability genuinely needs to be a
-   tool (structured I/O the agent invokes) but isn't core-fundamental, prefer
-   building it as an MCP server and adding it to the MCP catalog over growing
-   the core toolset. The agent connects to it through the built-in MCP client;
-   zero permanent core-schema footprint, and it's reusable by any MCP host.
-6. **New core tool** — only when the capability is fundamental, broadly useful
-   to nearly every user, and unreachable via terminal + file (or an MCP server).
-   Examples of correct core tools: terminal, read_file, web_search,
-   browser_navigate.
-
-When 3+ open PRs try to integrate the same *category* of thing (memory
-backends, providers, notifiers), don't merge them one at a time — design an
-ABC + orchestrator, wrap the existing built-in as the first provider, and turn
-the competing PRs into plugins against that interface.

It is an Electron + React + nanostore renderer (`@assistant-ui/react`) that talks to a `tui_gateway` backend over JSON-RPC (`requestGateway(method, params)`). The WebSocket/JSON-RPC transport lives in the framework-agnostic `apps/shared` package (`@hermes/shared` — `JsonRpcGatewayClient` + WS URL helpers), which the web dashboard (`web/`) also consumes; **desktop has no build/runtime dependency on the dashboard frontend** — it spawns a headless `hermes serve` backend server (the same gateway `dashboard` serves, minus the browser UI). `dashboard` and `serve` share `cmd_dashboard`/`start_server` but are independent surfaces — neither launches the other. The one exception is a backward-compat *fallback*: `serve` is newer, so the desktop spawn (`electron/backend-command.cjs` + `backendSupportsServe()` in `main.cjs`) detects whether the resolved runtime registers `serve` and, only when it does not (an older managed install / PATH `hermes` the app hasn't updated yet), rewrites the argv to the legacy `dashboard --no-open`. Without that, a new app against an un-upgraded runtime would crash on an unknown subcommand and brick every mid-upgrade user. It does NOT embed `hermes --tui` — it has its own composer, transcript, and slash-command pipeline. Route desktop bugs to the `hermes-desktop-app-work` skill, not `hermes-dashboard-work`.

 ### `_last_resolved_tool_names` is a process-global in `model_tools.py`

 `_run_single_child()` in `delegate_tool.py` saves and restores this global around subagent execution. If you add new code that reads this global, be aware it may be temporarily stale during child agent runs.
 
 ### DO NOT hardcode cross-tool references in schema descriptions
+
 Tool schema descriptions must not mention tools from other toolsets by name (e.g., `browser_navigate` saying "prefer web_search"). Those tools may be unavailable (missing API keys, disabled toolset), causing the model to hallucinate calls to non-existent tools. If a cross-reference is needed, add it dynamically in `get_tool_definitions()` in `model_tools.py` — see the `browser_navigate` / `execute_code` post-processing blocks for the pattern.

+- Pass `--no-isolate` to disable isolation — useful when debugging a single
+  test interactively, or when you specifically want to verify state leakage.
+- The plugin disables itself in child processes (sentinel envvar
+  `HERMES_ISOLATE_CHILD=1`), so there's no fork-bomb risk.
 
+### Why the wrapper (and why the old "just call pytest" doesn't work)
+
+Five real sources of local-vs-CI drift the script closes:
+
+|                     | Without wrapper                             | With wrapper                                                         |
+| ------------------- | ------------------------------------------- | -------------------------------------------------------------------- |
+| Provider API keys   | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset                                 |
+| HOME / `~/.hermes/` | Your real config+auth.json                  | Temp dir per test                                                    |
+| Timezone            | Local TZ (PDT etc.)                         | UTC                                                                  |
+| Locale              | Whatever is set                             | C.UTF-8                                                              |
+| xdist workers       | `-n auto` = all cores                       | `-n auto` (safe — subprocess isolation prevents cross-worker flakes) |
+
+`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
+invocation (including IDE integrations) gets hermetic behavior — but the wrapper
+is belt-and-suspenders.
+
+### Running without the wrapper (only if you must)
+
+If you can't use the wrapper (e.g. inside an IDE that shells pytest directly),
+at minimum activate the venv. The isolation plugin loads automatically from
+`addopts` in `pyproject.toml`, so you get the same per-test process isolation
+either way.
+
+```bash
+source .venv/bin/activate   # or: source venv/bin/activate
+python -m pytest tests/ -q
+```
+
+If you need to bypass isolation for fast feedback while debugging:
+
+```bash
+python -m pytest tests/agent/test_foo.py -q --no-isolate
+```
+
+Always run the full suite before pushing changes.

-# Contribuir a Hermes Agent
-
-¡Gracias por contribuir a Hermes Agent! Esta guía cubre todo lo que necesitas: configurar tu entorno de desarrollo, entender la arquitectura, decidir qué construir y conseguir que tu PR sea aceptado.
-
----
-
-## Prioridades de Contribución
-
-Valoramos las contribuciones en este orden:
-
-1. **Correcciones de errores** — bloqueos, comportamiento incorrecto, pérdida de datos. Siempre la máxima prioridad.
-2. **Compatibilidad entre plataformas** — macOS, diferentes distribuciones de Linux y WSL2 en Windows. Queremos que Hermes funcione en todas partes.
-3. **Fortalecimiento de seguridad** — inyección de shell, inyección de prompts, traversal de rutas, escalada de privilegios. Ver [Consideraciones de Seguridad](#consideraciones-de-seguridad).
-4. **Rendimiento y robustez** — lógica de reintento, manejo de errores, degradación elegante.
-5. **Nuevas habilidades** — pero solo las ampliamente útiles. Ver [¿Debería ser una Habilidad o una Herramienta?](#debería-ser-una-habilidad-o-una-herramienta)
-6. **Nuevas herramientas** — raramente necesarias. La mayoría de las capacidades deberían ser habilidades. Ver más abajo.
-7. **Documentación** — correcciones, aclaraciones, nuevos ejemplos.
-
----
-
-## ¿Debería ser una Habilidad o una Herramienta?
-
-Esta es la pregunta más común para los nuevos colaboradores. La respuesta casi siempre es **habilidad**.
-
-### Hazlo una Habilidad cuando:
-
-- La capacidad se puede expresar como instrucciones + comandos de shell + herramientas existentes
-- Envuelve una CLI externa o API que el agente puede llamar a través de `terminal` o `web_extract`
-- No necesita integración personalizada de Python ni gestión de claves API integrada en el agente
-- Ejemplos: búsqueda en arXiv, flujos de trabajo de git, gestión de Docker, procesamiento de PDF, email a través de herramientas CLI
-
-### Hazlo una Herramienta cuando:
-
-- Requiere integración de extremo a extremo con claves API, flujos de autenticación o configuración de múltiples componentes gestionada por el harness del agente
-- Necesita lógica de procesamiento personalizada que debe ejecutarse con precisión en cada ocasión (no "mejor esfuerzo" de la interpretación del LLM)
-- Maneja datos binarios, streaming o eventos en tiempo real que no pueden pasar por el terminal
-- Ejemplos: automatización de navegador (gestión de sesiones Browserbase), TTS (codificación de audio + entrega en plataforma), análisis de visión (manejo de imágenes base64)
-
-### ¿Debería la Habilidad estar incluida?
-
-Las habilidades incluidas (en `skills/`) se envían con cada instalación de Hermes. Deben ser **ampliamente útiles para la mayoría de los usuarios**:
-
-- Manejo de documentos, investigación web, flujos de trabajo de desarrollo comunes, administración de sistemas
-- Usadas regularmente por una amplia gama de personas
-
-Si tu habilidad es oficial y útil pero no universalmente necesaria (ej., una integración de servicio de pago, una dependencia pesada), ponla en **`optional-skills/`** — se envía con el repositorio pero no está activada por defecto. Los usuarios pueden descubrirla a través de `hermes skills browse` (etiquetada como "oficial") e instalarla con `hermes skills install` (sin advertencia de terceros, confianza integrada).
-
-Si tu habilidad es especializada, contribuida por la comunidad o de nicho, es mejor para un **Skills Hub** — súbela a un registro de habilidades y compártela en el [Discord de Nous Research](https://discord.gg/NousResearch). Los usuarios pueden instalarla con `hermes skills install`.
-
----
-
-## Proveedores de Memoria: Publicar como Plugin Independiente
-
-**Ya no aceptamos nuevos proveedores de memoria en este repositorio.** El conjunto de proveedores integrados en `plugins/memory/` (honcho, mem0, supermemory, byterover, hindsight, holographic, openviking, retaindb) está cerrado. Si quieres añadir un nuevo backend de memoria, publícalo como un **repositorio de plugin independiente** que los usuarios instalen en `~/.hermes/plugins/` (o a través de un entry point de pip).
-
-Los plugins de memoria independientes:
-
-- Implementan el mismo ABC `MemoryProvider` (`agent/memory_provider.py`) — `sync_turn`, `prefetch`, `shutdown` y opcionalmente `post_setup(hermes_home, config)` para integración con el asistente de configuración
-- Usan el mismo sistema de descubrimiento — `discover_memory_providers()` los recoge desde directorios de plugins de usuario/proyecto y entry points de pip
-- Se integran con `hermes memory setup` a través de `post_setup()` — sin necesidad de tocar el código base
-- Pueden registrar sus propios subcomandos CLI a través de `register_cli(subparser)` en un archivo `cli.py`
-- Obtienen todos los mismos hooks de ciclo de vida y plomería de configuración que los proveedores incluidos en el árbol
-
-Los PRs que añadan un nuevo directorio bajo `plugins/memory/` serán cerrados con un puntero para publicar el proveedor como su propio repositorio. Los proveedores en árbol existentes se mantienen; las correcciones de errores para ellos son bienvenidas.
-
-Esto no es una barra de calidad — es una decisión de acoplamiento y mantenimiento. Los proveedores de memoria son el tipo de plugin más común y no deberían vivir todos en este árbol.

-## Configuración del Desarrollo
-
-### Prerequisitos
-
-| Requisito | Notas |
-|-----------|-------|
-| **Git** | Con la extensión `git-lfs` instalada |
-| **Python 3.11+** | uv lo instalará si falta |
-| **uv** | Gestor de paquetes Python rápido ([instalar](https://docs.astral.sh/uv/)) |
-| **Node.js 20+** | Opcional — necesario para herramientas de navegador y puente WhatsApp (coincide con los engines de `package.json` raíz) |
-
-### Clonar e instalar
-
-```bash
-git clone https://github.com/NousResearch/hermes-agent.git
-cd hermes-agent
-
-# Crear venv con Python 3.11
-uv venv venv --python 3.11
-export VIRTUAL_ENV="$(pwd)/venv"
-
-# Instalar con todos los extras (mensajería, cron, menús CLI, herramientas de desarrollo)
-uv pip install -e ".[all,dev]"
-
-# Opcional: herramientas de navegador
-npm install
-```
-
-### Configurar para desarrollo
-
-```bash
-mkdir -p ~/.hermes/{cron,sessions,logs,memories,skills}
-cp cli-config.yaml.example ~/.hermes/config.yaml
-touch ~/.hermes/.env
-
-# Añadir al menos una clave de proveedor LLM:
-echo "OPENROUTER_API_KEY=***" >> ~/.hermes/.env
-```
-
-### Ejecutar
-
-```bash
-# Enlace simbólico para acceso global
-mkdir -p ~/.local/bin
-ln -sf "$(pwd)/venv/bin/hermes" ~/.local/bin/hermes
-
-# Verificar
-hermes doctor
-hermes chat -q "Hola"
-```
-
-### Ejecutar tests
-
-```bash
-# Preferido — coincide con CI (entorno hermético, 4 workers xdist); ver AGENTS.md
-scripts/run_tests.sh
-
-# Alternativa (activa el venv primero). El wrapper sigue recomendándose
-# para paridad con GitHub Actions antes de abrir un PR:
-pytest tests/ -v
-```

-
-### Patrones de Diseño Clave
-
-- **Herramientas auto-registradas**: Cada archivo de herramienta llama a `registry.register()` en el momento de importación. `model_tools.py` activa el descubrimiento importando todos los módulos de herramientas.
-- **Agrupación en toolsets**: Las herramientas se agrupan en toolsets (`web`, `terminal`, `file`, `browser`, etc.) que pueden habilitarse/deshabilitarse por plataforma.
-- **Persistencia de sesión**: Todas las conversaciones se almacenan en SQLite (`hermes_state.py`) con búsqueda de texto completo y títulos de sesión únicos.
-- **Inyección efímera**: Los prompts del sistema y los mensajes de relleno se inyectan en el momento de la llamada API, nunca se persisten en la base de datos ni en los logs.
-- **Abstracción de proveedor**: El agente funciona con cualquier API compatible con OpenAI. La resolución del proveedor ocurre en el momento de la inicialización.
-- **Enrutamiento de proveedor**: Al usar OpenRouter, `provider_routing` en config.yaml controla la selección del proveedor.
-
----
-
-## Estilo de Código
-
-- **PEP 8** con excepciones prácticas (no imponemos longitud de línea estricta)
-- **Comentarios**: Solo cuando se explica la intención no obvia, compromisos o peculiaridades de API. No narres lo que hace el código
-- **Manejo de errores**: Captura excepciones específicas. Registra con `logger.warning()`/`logger.error()` — usa `exc_info=True` para errores inesperados
-- **Multiplataforma**: Nunca asumas Unix. Ver [Compatibilidad Multiplataforma](#compatibilidad-multiplataforma)
-
----
-
-## Añadir una Nueva Herramienta
-
-Antes de escribir una herramienta, pregúntate: [¿debería ser una habilidad en su lugar?](#debería-ser-una-habilidad-o-una-herramienta)
-
-Las herramientas se auto-registran en el registro central. Cada archivo de herramienta co-localiza su esquema, manejador y registro:
-
-```python
-"""my_tool — Breve descripción de lo que hace esta herramienta."""
-
-import json
-from tools.registry import registry
-
-
-def my_tool(param1: str, param2: int = 10, **kwargs) -> str:
-    """Manejador. Devuelve un resultado en cadena (a menudo JSON)."""
-    result = do_work(param1, param2)
-    return json.dumps(result)
-
-
-MY_TOOL_SCHEMA = {
-    "type": "function",
-    "function": {
-        "name": "my_tool",
-        "description": "Qué hace esta herramienta y cuándo debería usarla el agente.",
-        "parameters": {
-            "type": "object",
-            "properties": {
-                "param1": {"type": "string", "description": "Qué es param1"},
-                "param2": {"type": "integer", "description": "Qué es param2", "default": 10},
-            },
-            "required": ["param1"],
-        },
-    },
-}
-
-
-def _check_requirements() -> bool:
-    """Devuelve True si las dependencias de esta herramienta están disponibles."""
-    return True
-
-
-registry.register(
-    name="my_tool",
-    toolset="my_toolset",
-    schema=MY_TOOL_SCHEMA,
-    handler=lambda args, **kw: my_tool(**args, **kw),
-    check_fn=_check_requirements,
-)
-```
-
-**Conectar a un toolset (requerido):** Las herramientas integradas se auto-descubren: cualquier
-archivo `tools/*.py` que contenga una llamada de nivel superior `registry.register(...)` es
-importado por `discover_builtin_tools()` en `tools/registry.py` cuando `model_tools`
-se carga. **No** hay una lista de importaciones manual en `model_tools.py` que mantener.
-
-Todavía debes añadir el nombre de la herramienta a la lista apropiada en `toolsets.py`
-(por ejemplo `_HERMES_CORE_TOOLS` o un toolset dedicado); de lo contrario la herramienta
-se registra pero nunca se expone al agente.
-
-Consulta `AGENTS.md` (sección **Adding New Tools**) para rutas conscientes del perfil y
-orientación sobre plugins vs. núcleo.
-
----
-
-## Añadir una Habilidad
-
-Las habilidades incluidas viven en `skills/` organizadas por categoría. Las habilidades opcionales oficiales usan la misma estructura en `optional-skills/`:
-
-```

-
-### Estándares de autoría de habilidades (OBLIGATORIOS)
-
-Todo skill nuevo o modernizado — incluido, opcional o contribuido — debe cumplir estos estándares antes del merge:
-
-1. **`description` ≤ 60 caracteres, una oración, termina con punto.** Las descripciones largas saturan la UI de listado de habilidades. Indica la capacidad, no la implementación. Sin palabras de marketing ("potente", "completo", "fluido", "avanzado").
-
-2. **Las herramientas referenciadas en el cuerpo de SKILL.md deben ser herramientas nativas de Hermes o servidores MCP que la habilidad espere explícitamente.** Usa los nombres de herramientas en comillas invertidas: `` `terminal` ``, `` `web_extract` ``, `` `web_search` ``, `` `read_file` ``, `` `write_file` ``, etc.
-
-3. **El campo `platforms:` auditado contra las importaciones reales del script.** Las habilidades que usen primitivos solo de POSIX deben declarar sus plataformas soportadas.
-
-4. **`author` da crédito primero al colaborador humano.**
-
-5. **El cuerpo de SKILL.md usa el orden moderno de secciones:** título, intro de 2-3 oraciones, luego: `## Cuándo Usar`, `## Prerequisitos`, `## Cómo Ejecutar`, `## Referencia Rápida`, `## Procedimiento`, `## Problemas Conocidos`, `## Verificación`.
-
-6. **Los scripts van en `scripts/`, las referencias en `references/`, las plantillas en `templates/`.**
-
-7. **Los tests viven en `tests/skills/test_<skill>_skill.py`** y usan solo stdlib + pytest + `unittest.mock`. Sin llamadas de red en vivo.
-
-8. **Las adiciones a `.env.example` están aisladas en un bloque claramente delimitado.**
-

-## Añadir una Skin / Tema
-
-Hermes usa un sistema de skins basado en datos — no se necesitan cambios de código para añadir una nueva skin.
-
-**Opción A: Skin de usuario (archivo YAML)**
-
-Crea `~/.hermes/skins/<nombre>.yaml`:
-
-```yaml

-## Compatibilidad Multiplataforma
-
-Hermes se ejecuta en Linux, macOS y Windows nativo (además de WSL2). Al escribir código
-que toca el SO, asume que *cualquier* plataforma puede alcanzar tu ruta de código.
-
-> **Antes de hacer PR:** ejecuta `scripts/check-windows-footguns.py` para detectar
-> los patrones inseguros comunes de Windows en tu diff. Es basado en grep y barato;
-> CI también lo ejecuta en cada PR.
-
-### Reglas críticas
-
-1. **Nunca llames `os.kill(pid, 0)` para comprobaciones de liveness.** En Windows **NO es una operación sin efecto**. Usa `psutil.pid_exists(pid)` en su lugar.
-
-2. **Usa `shutil.which()` antes de hacer shell — no asumas que Windows tiene las herramientas que tiene Linux.** `ps`, `kill`, `grep`, `awk`, etc. simplemente no existen en Windows.
-
-3. **`termios` y `fcntl` son solo de Unix.** Siempre captura tanto `ImportError` como `NotImplementedError`.
-
-4. **Codificación de archivos.** Windows puede guardar archivos `.env` en `cp1252`. Siempre maneja errores de codificación.
-
-5. **Gestión de procesos.** `os.setsid()`, `os.killpg()`, `os.fork()`, `os.getuid()` y el manejo de señales POSIX difieren en Windows.
-
-6. **Señales que no existen en Windows:** `SIGALRM`, `SIGCHLD`, `SIGHUP`, `SIGUSR1`, `SIGUSR2`, etc.
-
-7. **Separadores de ruta.** Usa `pathlib.Path` en lugar de concatenación de cadenas con `/`.
-
-8. **Los enlaces simbólicos necesitan privilegios elevados en Windows** (a menos que el Modo Desarrollador esté activado).
-
-9. **Los modos de archivo POSIX (0o600, 0o644, etc.) NO se aplican en NTFS** por defecto.
-
-10. **Los daemons de fondo desacoplados en Windows necesitan `pythonw.exe`, NO `python.exe`.**

-## Consideraciones de Seguridad
-
-Hermes tiene acceso al terminal. La seguridad importa.
-
-### Protecciones existentes
-
-| Capa | Implementación |
-|------|---------------|
-| **Piping de contraseña sudo** | Usa `shlex.quote()` para prevenir inyección de shell |
-| **Detección de comandos peligrosos** | Patrones regex en `tools/approval.py` con flujo de aprobación del usuario |
-| **Inyección de prompts en cron** | Escáner en `tools/cronjob_tools.py` bloquea patrones de anulación de instrucciones |
-| **Lista de denegación de escritura** | Rutas protegidas resueltas a través de `os.path.realpath()` para prevenir bypass de enlaces simbólicos |
-| **Skills Guard** | Escáner de seguridad para habilidades instaladas desde el hub (`tools/skills_guard.py`) |
-| **Sandbox de ejecución de código** | El proceso hijo `execute_code` se ejecuta con claves API eliminadas del entorno |
-| **Fortalecimiento de contenedor** | Docker: todas las capacidades eliminadas, sin escalada de privilegios, límites de PID, tmpfs de tamaño limitado |
-
-### Al contribuir código sensible a la seguridad
-
-- **Siempre usa `shlex.quote()`** al interpolar entrada del usuario en comandos de shell
-- **Resuelve enlaces simbólicos** con `os.path.realpath()` antes de comprobaciones de control de acceso basadas en rutas
-- **No registres secretos.** Las claves API, tokens y contraseñas nunca deben aparecer en la salida de log
-- **Captura excepciones amplias** alrededor de la ejecución de herramientas para que un solo fallo no bloquee el bucle del agente
-- **Prueba en todas las plataformas** si tu cambio toca rutas de archivos, gestión de procesos o comandos de shell
-
-### Política de fijación de dependencias (fortalecimiento de la cadena de suministro)
-
-Tras el [compromiso de la cadena de suministro de litellm](https://github.com/BerriAI/litellm/issues/24512) en marzo de 2026 y la [campaña del gusano Mini Shai-Hulud](https://socket.dev/blog/tanstack-npm-packages-compromised-mini-shai-hulud-supply-chain-attack) en mayo de 2026, todas las dependencias deben seguir estas reglas:
-
-| Tipo de fuente | Tratamiento requerido | Justificación |
-|---|---|---|
-| **Paquete PyPI** | `>=suelo,<siguiente_mayor` | Las versiones de PyPI son inmutables una vez publicadas, pero pueden empujarse nuevas versiones en tu rango. |
-| **URL de Git** | SHA completo del commit | Las ramas y etiquetas son refs mutables; el SHA está direccionado por contenido. |
-| **GitHub Actions** | SHA completo del commit + comentario de versión | Las etiquetas de acción son refs mutables. Fija como `uses: owner/action@<sha>  # vX.Y.Z` |
-| **Instalaciones pip solo de CI** | `==exacto` | Builds de CI herméticos; el cambio es aceptable. |
-
-**Cada nueva dependencia de PyPI en un PR debe tener un límite superior `<siguiente_mayor`.** Los PRs que añadan especificaciones `>=X.Y.Z` sin límite superior serán rechazados.

-## Before You Start: Search First
-
-A quick search before you build saves your time and keeps the PR queue clean — duplicates are common here, so it's worth a minute up front.
-
-- **Search both open *and* merged PRs and issues** for your topic or error symptom — the duplicate-check in the PR template fires at review time, after you've already done the work:
-  ```bash
-  gh search issues --repo NousResearch/hermes-agent "<your terms>"
-  gh search prs --repo NousResearch/hermes-agent --state all "<your terms>"
-  ```
-  Or use the web UI: [issues](https://github.com/NousResearch/hermes-agent/issues?q=) · [PRs (all states)](https://github.com/NousResearch/hermes-agent/pulls?q=is%3Apr).
-- **The issue tracker can lag the code.** Many requested features are already implemented in-tree, so also search the source (`search_files`, or your editor's grep) for the capability before proposing it.
-- **If an open PR already addresses it**, consider reviewing or improving that one instead of opening a competing duplicate.
-- **For larger work**, comment on the issue to signal you're working on it, so others don't start the same thing.

-## Third-Party Product Integrations: Ship as a Standalone Plugin
-
-The same rule extends to **any plugin that integrates someone else's product or project** — observability/metrics backends, vendor SaaS connectors, analytics dashboards, paid-service tie-ins, and similar third-party integrations. **These do not land in this repo.**
-
-The reason is maintenance load, not quality. Every external product absorbed into the core tree becomes ours to keep working against a fast-moving codebase, for a backend we don't own and can't control. Hermes ships a lot and the core moves quickly; coupling third-party products into it creates an open-ended burden on the maintainers.
-
-Publish these as a **standalone plugin repo** instead:
-
-- Implement the relevant ABC and use the existing plugin discovery path (`~/.hermes/plugins/`, project `.hermes/plugins/`, or a pip entry point) — see [Build a Hermes Plugin](https://hermes-agent.nousresearch.com/docs/guides/build-a-hermes-plugin)
-- Register lifecycle hooks (`pre_tool_call`, `post_tool_call`, `pre_llm_call`, `post_llm_call`, `on_session_start`, `on_session_end`), tools (`ctx.register_tool`), and CLI subcommands (`ctx.register_cli_command`) through the surface we already expose — no core changes needed
-- If your plugin needs a capability the framework doesn't expose, that's a feature request to **widen the generic plugin surface** (a new hook or `ctx` method) — never special-case your plugin in core
-- Promote it in the [Nous Research Discord](https://discord.gg/NousResearch) `#plugins-skills-and-skins` channel so users can find and install it
-
-A well-built third-party-product plugin can clear automated review and still be closed for this reason — it's a placement decision, not a verdict on the code. PRs that add such a directory under `plugins/` will be closed with a pointer to publish it as its own repo.

-### Install with the standard installer
-
-For most contributors, the best development bootstrap is the same path users
-take: run the standard installer, then work inside the repository it cloned.
-The installer creates the Hermes venv, wires the `hermes` command, stamps the
-install method for `hermes update`, and clones the full git project into
-`$HERMES_HOME/hermes-agent` (usually `~/.hermes/hermes-agent`). That keeps your
-development environment on the same layout the CLI, updater, lazy dependency
-installer, gateway, and docs assume.
-
-```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
-cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
-
-# Add dev/test extras on top of the standard install.
-uv pip install -e ".[all,dev]"
-
-# Optional: browser tools / docs site dependencies.
-npm install
-```
-
-After that, create branches and run tests from that checkout:
-
-```bash
-git checkout -b fix/description
-scripts/run_tests.sh
-```
-
-### Manual clone fallback
-
-Use this only if you intentionally do not want Hermes' managed install layout
-(for example, a throwaway clone inside a container or CI job). If you install
-this way, make sure you run the `hermes` entrypoint from this venv; running the
-system `python3 -m hermes_cli.main` can pick up unrelated system Python
-packages.
-
-Create the venv **outside** the cloned source tree. A venv that lives inside
-the directory the agent operates from can be wiped by a relative-path command
-the agent runs against its own checkout (`rm -rf venv`, `uv venv venv`, etc.),
-which silently destroys the running runtime mid-session. Keeping it outside the
-tree means no relative path from the workspace resolves to it.
+### Clone and install
 
 ```bash
 git clone https://github.com/NousResearch/hermes-agent.git

+# Plan: Split `_cmd_update_impl` into pull + post-pull phases
+
+## Problem
+After `git pull` (or ZIP extraction) overwrites source files on disk, the
+running Python process still has the **old** code in `sys.modules` and
+`__pycache__`. The current monolith runs post-pull steps (pip install, node
+deps, skills sync, config migration, gateway restart) under stale bytecode,
+which causes `ImportError` on gateway restart and subtle drift bugs.
+
+## Solution: Two-phase update with re-exec
+
+Split `_cmd_update_impl` into:
+
+1. **`_cmd_update_pull_new_version`** — download new code onto disk
+2. **Re-exec** into a fresh Python process
+3. **`_cmd_update_post_pull`** — run all post-pull steps under the new code
+
+The re-exec guarantees a clean `sys.modules` / `__pycache__` for phase 2.
+
+---
+
+## Phase 1: `_cmd_update_pull_new_version(args, gateway_mode)`
+
+Everything up to and including "code is on disk, stash is restored":
+
+1. Windows concurrent-hermes guard (exit 2 if locked)
+2. Pre-update backup (`_run_pre_update_backup`)
+3. Route detection:
+   - No `.git` + Windows → `_update_files_via_zip` (download + extract only)
+   - No `.git` + non-Windows + pip → **error** (pip self-update ripped out)
+   - No `.git` + non-Windows → reinstall hint + exit 1
+   - `.git` exists → git flow (below)
+4. Git config setup (autocrlf, appendAtomically)
+5. Discard lockfile churn
+6. Fork detection + origin URL check
+7. Fetch + branch logic + stash
+8. Check for new commits (if 0, restore + "already up to date" + return)
+9. Pre-update snapshot (`create_quick_snapshot`)
+10. `git pull --ff-only` (or `reset --hard` on divergence)
+11. Post-pull syntax guard (`_validate_critical_files_syntax`) + rollback on failure
+12. Restore stashed changes
+13. `_invalidate_update_cache()`
+14. `_clear_bytecode_cache()`
+
+At this point new code is on disk and the working tree is clean.
+**Return `True`** to signal "re-exec needed".
+
+### ZIP path change
+
+`_update_files_via_zip` currently does the full pipeline (download, extract,
+clear bytecode, pip install, node deps, skills sync, curator notices, kill
+dashboard). We split it:
+
+- **`_update_files_via_zip`** → rename to `_download_and_extract_zip(args)`:
+  downloads + extracts + clears bytecode. Returns `True` when new code landed.
+- The pip install / node deps / skills sync / etc moves to
+  `_cmd_update_post_pull` (shared by both git and zip).
+
+### Already-up-to-date fast path
+
+If git reports 0 new commits (or zip extraction shows no changes), we return
+`False` from pull — no re-exec needed. The caller prints "already up to date"
+and exits cleanly.
+
+---
+
+## Re-exec mechanism
+
+After `_cmd_update_pull_new_version` returns `True`:
+
+```python
+def _reexec_for_post_pull(args, gateway_mode: bool):
+    """Replace this process with a fresh Python running --post-pull."""
+    argv = list(sys.argv)
+    # Insert --post-pull before any positional args (there shouldn't be any)
+    argv.append("--post-pull")
+
+    if gateway_mode:
+        argv.append("--gateway")
+
+    # Pass pre-update snapshot ID if we have one
+    snapshot_id = getattr(args, "_pre_update_snapshot_id", None)
+    if snapshot_id:
+        argv.extend(["--pre-update-snapshot", snapshot_id])
+
+    if sys.platform == "win32":
+        # Windows: os.execvp internally does spawn+exit (PID changes).
+        # The bootstrap installer watches the original PID via run_streamed().
+        # If we execvp, the installer sees exit-0 before post-pull finishes.
+        # Instead: relay through a subprocess so the parent PID stays alive
+        # until the child completes. The installer's child.wait() sees the
+        # real exit code.
+        result = subprocess.run([sys.executable, "-m", "hermes_cli.main"] + argv)
+        sys.exit(result.returncode)
+    else:
+        # POSIX: true exec — same PID, no stale modules.
+        os.execvp(sys.executable, [sys.executable, "-m", "hermes_cli.main"] + argv)
+```
+
+### Why subprocess.run on Windows (not Popen+exit)
+
+`Popen` + `sys.exit` has a race: if the parent exits before the child's
+stdout pipe is drained, the bootstrap installer's `BufReader` gets a broken
+pipe and the child may get SIGPIPE. `subprocess.run` waits for the child to
+finish and properly reaps it, then we forward the exit code. This is
+functionally identical to what the bootstrap installer already does when it
+spawns `hermes update` directly.
+
+### Gateway output file continuity
+
+In gateway mode, `hermes update --gateway` writes to an output file that the
+gateway watches. On POSIX, `os.execvp` inherits FDs so the output file
+continues being written. On Windows, the relay subprocess inherits the
+same FDs (subprocess.run passes them through). The `--gateway` flag is
+passed to the child so `_install_hangup_protection` / `_finalize_update_output`
+work correctly.
+
+**However**, the gateway's spawn path (gateway/run.py) launches the update
+detached with its own output redirection. The output file is opened by the
+*child*, not inherited from the parent. So on the re-exec path the child
+re-opens the same output path via `_install_hangup_protection` (which
+already sets up the update.log mirror). No special handling needed.
+
+### Bootstrap installer interaction
+
+The Windows bootstrap installer (`update.rs`) calls `hermes update --yes
+--gateway` via `run_streamed()`, which:
+
+1. Spawns the hermes binary as a child process
+2. Reads stdout/stderr line-by-line
+3. Waits for exit via `child.wait().await`
+4. Checks exit code (0 = success, 2 = concurrent lock)
+
+Our Windows relay pattern is safe because:
+- The **parent** (original `hermes update` PID) stays alive until the
+  **child** (post-pull phase) exits
+- `child.wait()` in the installer sees the parent exit only after the
+  child finishes → correct exit code propagation
+- The parent's stdout/stderr are piped to the installer's `BufReader`;
+  the child inherits those FDs, so output streams continue seamlessly
+
+---
+
+## Phase 2: `_cmd_update_post_pull(args, gateway_mode)`
+
+All post-pull steps, running under freshly-exec'd Python with clean
+`sys.modules`. Steps are identical regardless of whether code arrived via
+git or zip:
+
+1. `_refresh_active_lazy_features()`
+2. Python dependency install (uv/pip — the entire `ensure_uv` +
+   `_install_python_dependencies_with_optional_fallback` block)
+3. `_update_node_dependencies()`
+4. `_build_web_ui`
+5. Desktop app rebuild check + build
+6. Skills sync (`sync_skills` + profile seed)
+7. Honcho profile sync
+8. Config migration (missing env, missing config, version bump, interactive prompts)
+9. Cron jobs safety-net restore
+10. Curator notices (first-run + recent-run)
+11. FHS PATH guard
+12. cua-driver refresh (macOS)
+13. Gateway restart (systemd, launchd, manual processes, survivor sweep)
+14. Legacy unit warning
+15. Kill stale dashboard processes
+16. Print "Update complete!" + tip
+
+---
+
+## Argparse changes
+
+Add to `update_parser`:
+
+```python
+update_parser.add_argument(
+    "--post-pull",
+    action="store_true",
+    default=False,
+    help=argparse.SUPPRESS,  # internal flag — not for users
+)
+update_parser.add_argument(
+    "--pre-update-snapshot",
+    default=None,
+    metavar="ID",
+    help=argparse.SUPPRESS,  # carries snapshot ID across re-exec
+)
+```
+
+## `cmd_update` dispatch changes
+
+```python
+def cmd_update(args):
+    # ... existing managed/docker/check guards ...
+
+    _update_io_state = _install_hangup_protection(gateway_mode=gateway_mode)
+    try:
+        if getattr(args, "post_pull", False):
+            _cmd_update_post_pull(args, gateway_mode=gateway_mode)
+        else:
+            needs_reexec = _cmd_update_pull_new_version(args, gateway_mode=gateway_mode)
+            if needs_reexec:
+                _reexec_for_post_pull(args, gateway_mode=gateway_mode)
+            # if not needs_reexec, we're already done (already up to date)
+    finally:
+        _finalize_update_output(_update_io_state)
+```
+
+**Important**: `_finalize_update_output` runs in the parent on the
+non-reexec path. On the re-exec path, it runs in the parent *before*
+the exec replaces the process. On Windows relay, it runs before
+`subprocess.run`. The post-pull child has its own
+`_install_hangup_protection` / `_finalize_update_output` cycle because
+`cmd_update` is re-entered via the fresh process.
+
+Wait — actually on the re-exec path the parent process is *replaced* (POSIX)
+or *exits* (Windows relay). So `_finalize_update_output` would run in the
+`finally` block *after* `_reexec_for_post_pull` returns. But on POSIX,
+`os.execvp` never returns (or raises on failure). On Windows,
+`sys.exit(result.returncode)` never returns. So the `finally` block only
+runs if `_reexec_for_post_pull` raises (e.g. execvp fails). That's the
+right behavior — cleanup only on failure.
+
+On the post-pull path, `cmd_update` is called fresh in the new process,
+so `_install_hangup_protection` + `_finalize_update_output` wrap the
+post-pull phase correctly.
+
+---
+
+## Pip install path: RIP
+
+`_cmd_update_pip` is removed. `cmd_update` already checks for
+`is_managed()` and `detect_install_method() == "docker"` before entering
+the impl. We add pip to the early-exit guards:
+
+```python
+def cmd_update(args):
+    # ... existing is_managed() check ...
+
+    if detect_install_method(PROJECT_ROOT) == "docker":
+        print(format_docker_update_message())
+        sys.exit(1)
+
+    if detect_install_method(PROJECT_ROOT) == "pip":
+        from hermes_cli.config import recommended_update_command
+        print("✗ Self-update is not supported for pip/uv-tool installs.")
+        print(f"  Run '{recommended_update_command()}' instead.")
+        sys.exit(1)
+
+    # ... --check and --post-pull dispatch ...
+```
+
+Also update `_cmd_update_check` to keep its existing pip check path
+(it just checks PyPI — no code mutation, no re-exec needed).
+
+---
+
+## Cross-phase state
+
+| State | Mechanism |
+|-------|-----------|
+| `gateway_mode` | Passed via `--gateway` flag (already exists) |
+| `assume_yes` | Passed via `--yes` flag (already exists) |
+| `pre_update_snapshot_id` | New `--pre-update-snapshot` arg |
+| `auto_stash_ref` | NOT needed — stash is restored in phase 1 |
+| `branch` | Passed via `--branch` (already exists) |
+| `force` | Passed via `--force` (already exists) |
+| `backup` / `no_backup` | Passed via `--backup` / `--no-backup` (already exists) |
+
+The only new cross-phase arg is `--pre-update-snapshot`, because the
+snapshot is created in phase 1 but consumed in phase 2 (cron safety net).
+
+---
+
+## `_update_files_via_zip` refactor
+
+Rename current function to `_download_and_extract_zip(args) -> bool`:
+
+- Downloads ZIP, extracts, clears bytecode
+- Returns `True` if new code was written
+- Does NOT do pip install, node deps, skills sync, etc.
+
+The old post-extraction code moves to `_cmd_update_post_pull`.
+
+---
+
+## Test impact
+
+| Test file | Change needed |
+|-----------|--------------|
+| `test_cmd_update.py` | Update mocks for two-phase flow; test `--post-pull` dispatch |
+| `test_cmd_update_docker.py` | Minimal — docker bailout is unchanged |
+| `test_update_autostash.py` | Stash logic stays in phase 1 — should work as-is |
+| `test_update_concurrent_quarantine.py` | Concurrent check stays in phase 1 — should work as-is |
+| `test_managed_installs.py` | Add pip install error test (was previously allowed) |
+| `test_uv_tool_update.py` | Remove — pip/uv-tool self-update is now an error |
+
+---
+
+## Execution order summary
+
+```
+hermes update
+  └─ cmd_update()
+      ├─ is_managed? → error
+      ├─ docker? → error + hint
+      ├─ pip? → error + hint (NEW — was _cmd_update_pip)
+      ├─ --check? → _cmd_update_check() (unchanged)
+      ├─ --post-pull? → _cmd_update_post_pull() (phase 2)
+      └─ else → _cmd_update_pull_new_version() (phase 1)
+           ├─ download code (git pull or zip)
+           ├─ validate + stash restore + clear bytecode
+           └─ if new code: _reexec_for_post_pull()
+                ├─ POSIX: os.execvp → same PID, fresh Python
+                └─ Windows: subprocess.run + sys.exit → relay

-## Instalación rápida
-
-### Linux, macOS, WSL2, Termux
-
-```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
-```
-
-### Windows (nativo, PowerShell)
-
-> **Nota:** En Windows nativo, Hermes funciona sin WSL — la CLI, el gateway, la TUI y las herramientas funcionan de forma nativa. Si prefieres usar WSL2, el comando de Linux/macOS de arriba también funciona allí. ¿Encontraste un error? Por favor [crea un issue](https://github.com/NousResearch/hermes-agent/issues).
-
-Ejecuta esto en PowerShell:
-
-```powershell
-iex (irm https://hermes-agent.nousresearch.com/install.ps1)
-```
-
-El instalador se encarga de todo: uv, Python 3.11, Node.js, ripgrep, ffmpeg, **y un Git Bash portátil** (MinGit, descomprimido en `%LOCALAPPDATA%\hermes\git` — no requiere administrador, completamente aislado de cualquier instalación de Git del sistema). Hermes usa este Git Bash incluido para ejecutar comandos de shell.
-
-Si ya tienes Git instalado, el instalador lo detecta y lo usa en su lugar. De lo contrario, una descarga de ~45MB de MinGit es todo lo que necesitas — no tocará ni interferirá con ningún Git del sistema.
-
-> **Android / Termux:** La ruta manual probada está documentada en la [guía de Termux](https://hermes-agent.nousresearch.com/docs/getting-started/termux). En Termux, Hermes instala el extra `.[termux]` curado porque el extra completo `.[all]` actualmente incluye dependencias de voz incompatibles con Android.
->
-> **Windows:** Windows nativo es totalmente compatible — el comando de PowerShell de arriba instala todo. Si prefieres usar WSL2, el comando de Linux también funciona allí. La instalación nativa de Windows se encuentra en `%LOCALAPPDATA%\hermes`; WSL2 instala en `~/.hermes` como en Linux.
-
-Después de la instalación:
-
-```bash
-source ~/.bashrc    # recargar shell (o: source ~/.zshrc)
-hermes              # ¡empieza a chatear!
-```
-
----
-
-## Primeros pasos
-
-```bash
-hermes              # CLI interactiva — inicia una conversación
-hermes model        # Elige tu proveedor y modelo LLM
-hermes tools        # Configura qué herramientas están habilitadas
-hermes config set   # Establece valores de configuración individuales
-hermes gateway      # Inicia el gateway de mensajería (Telegram, Discord, etc.)
-hermes setup        # Ejecuta el asistente de configuración completo
-hermes claw migrate # Migra desde OpenClaw (si vienes de OpenClaw)
-hermes update       # Actualiza a la última versión
-hermes doctor       # Diagnostica cualquier problema
-```

-
-## Evita la colección de claves API — Nous Portal
-
-Hermes funciona con cualquier proveedor que quieras — eso no cambiará. Pero si prefieres no recopilar cinco claves API separadas para el modelo, búsqueda web, generación de imágenes, TTS y un navegador en la nube, **[Nous Portal](https://portal.nousresearch.com)** las cubre todas bajo una sola suscripción:
-
-- **Más de 300 modelos** — elige cualquiera con `/model <nombre>`
-- **Tool Gateway** — búsqueda web (Firecrawl), generación de imágenes (FAL), texto a voz (OpenAI), navegador en la nube (Browser Use), todo enrutado a través de tu suscripción. Sin cuentas adicionales.
-
-Un comando desde una instalación nueva:
-
-```bash
-hermes setup --portal
-```
-
-Esto te autentica vía OAuth, establece Nous como tu proveedor y activa el Tool Gateway. Comprueba qué está conectado en cualquier momento con `hermes portal info`. Detalles completos en la [página de documentación del Tool Gateway](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway).
-
-Puedes seguir usando tus propias claves por herramienta cuando quieras — el gateway es por backend, no todo o nada.
-
----
-
-## Referencia rápida: CLI vs Mensajería
-
-Hermes tiene dos puntos de entrada: inicia la interfaz de terminal con `hermes`, o ejecuta el gateway y habla con él desde Telegram, Discord, Slack, WhatsApp, Signal o Email. Una vez en una conversación, muchos comandos de barra son compartidos entre ambas interfaces.

 **The self-improving AI agent built by [Nous Research](https://nousresearch.com).** It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.

-### Troubleshooting
-
-#### Windows Defender or antivirus flags `uv.exe` as malware
-
-If your antivirus (Bitdefender, Windows Defender, etc.) quarantines `uv.exe` from the Hermes `bin` folder (`%LOCALAPPDATA%\hermes\bin\uv.exe`), this is a **false positive**. The file is Astral's `uv` — the Rust Python package manager Hermes bundles to manage its Python environment. ML-based antivirus engines commonly flag unsigned Rust binaries that download and install packages.
-
-**To verify your copy is authentic:**
-
-```powershell
-# Install GitHub CLI if needed
-winget install --id GitHub.cli
-
-# Login to GitHub
-gh auth login
-
-# Run verification
-$uv = "$env:LOCALAPPDATA\hermes\bin\uv.exe"
-$ver = (& $uv --version).Split(' ')[1]
-[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
-$zip = "$env:TEMP\uv.zip"
-Invoke-WebRequest "https://github.com/astral-sh/uv/releases/download/$ver/uv-x86_64-pc-windows-msvc.zip" -OutFile $zip -UseBasicParsing
-gh attestation verify $zip --repo astral-sh/uv
-Expand-Archive $zip "$env:TEMP\uv_x" -Force
-(Get-FileHash "$env:TEMP\uv_x\uv.exe").Hash -eq (Get-FileHash $uv).Hash
-```
-
-If attestation says "Verification succeeded" and the last line prints `True`, you're good.
-
-**To whitelist Hermes:**
-- **Windows Defender:** Run PowerShell as Admin → `Add-MpPreference -ExclusionPath "$env:LOCALAPPDATA\hermes\bin"`
-- **Bitdefender:** Add an exception in the Bitdefender console (Protection > Antivirus > Settings > Manage Exceptions)
-- Whitelist the **folder**, not the file hash — Hermes updates `uv` and the hash changes every version
-
-For more context, see the upstream Astral reports: [astral-sh/uv#13553](https://github.com/astral-sh/uv/issues/13553), [astral-sh/uv#15011](https://github.com/astral-sh/uv/issues/15011), [astral-sh/uv#10079](https://github.com/astral-sh/uv/issues/10079).

 We welcome contributions! See the [Contributing Guide](https://hermes-agent.nousresearch.com/docs/developer-guide/contributing) for development setup, code style, and PR process.
 
-Quick start for contributors — use the standard installer, then work from the
-full git checkout it creates at `$HERMES_HOME/hermes-agent` (usually
-`~/.hermes/hermes-agent`). This matches the layout used by `hermes update`, the
-managed venv, lazy dependencies, gateway, and docs tooling.
+Quick start for contributors — clone and go with `setup-hermes.sh`:
 
 ```bash
-curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
-cd "${HERMES_HOME:-$HOME/.hermes}/hermes-agent"
-uv pip install -e ".[all,dev]"
-scripts/run_tests.sh
+git clone https://github.com/NousResearch/hermes-agent.git
+cd hermes-agent
+./setup-hermes.sh     # installs uv, creates venv, installs .[all], symlinks ~/.local/bin/hermes
+./hermes              # auto-detects the venv, no need to `source` first
 ```
 
-Manual clone fallback (for throwaway clones/CI where you intentionally do not
-want the managed install layout):
-
-Create the venv outside the cloned source tree — a venv inside the directory
-the agent operates from can be wiped by a relative-path command the agent runs
-against its own checkout, destroying the running runtime mid-session.
+Manual path (equivalent to the above):
 
 ```bash
 curl -LsSf https://astral.sh/uv/install.sh | sh
-uv venv ~/.hermes/venvs/hermes-dev --python 3.11
-source ~/.hermes/venvs/hermes-dev/bin/activate

-انسٹالر سب کچھ خود سنبھالتا ہے: uv، Python 3.11، Node.js، ripgrep، ffmpeg، **اور ایک پورٹ ایبل (portable) گٹ بیش (Git Bash)** (یعنی MinGit، جو `%LOCALAPPDATA%\hermes\git` میں ان پیک ہوتا ہے — اس کے لیے ایڈمن کی اجازت درکار نہیں، اور یہ سسٹم کے کسی بھی گٹ انسٹال سے بالکل الگ ہے)۔ ہرمیس اس بنڈل شدہ گٹ بیش کو شیل کمانڈز چلانے کے لیے استعمال کرتا ہے۔
-
-اگر آپ کے پاس پہلے سے گٹ (Git) انسٹال ہے، تو انسٹالر اسے شناخت کر لیتا ہے اور اسے ہی استعمال کرتا ہے۔ بصورت دیگر آپ کو صرف ~45MB کے MinGit ڈاؤنلوڈ کی ضرورت ہوگی — یہ آپ کے سسٹم کے گٹ پر کوئی اثر نہیں ڈالے گا۔
-
-> **اینڈرائیڈ (Android) / ٹرمکس (Termux):** ٹیسٹ کیا گیا مینوئل طریقہ [Termux گائیڈ](https://hermes-agent.nousresearch.com/docs/getting-started/termux) میں موجود ہے۔ ٹرمکس پر ہرمیس ایک مخصوص `.[termux]` ایکسٹرا انسٹال کرتا ہے کیونکہ مکمل `.[all]` ایکسٹرا میں ایسی وائس ڈیپینڈینسیز شامل ہیں جو اینڈرائیڈ کے ساتھ مطابقت نہیں رکھتیں۔
->
-> **ونڈوز (Windows):** مقامی ونڈوز کی مکمل سپورٹ موجود ہے — اوپر دی گئی پاور شیل کی کمانڈ سب کچھ انسٹال کر دیتی ہے۔ اگر آپ WSL2 استعمال کرنا چاہتے ہیں، تو لینکس کی کمانڈ وہاں کام کرتی ہے۔ مقامی ونڈوز میں انسٹالیشن `%LOCALAPPDATA%\hermes` میں ہوتی ہے؛ جبکہ WSL2 میں لینکس کی طرح `~/.hermes` میں ہوتی ہے۔ ہرمیس کا وہ واحد فیچر جسے فی الحال خاص طور پر WSL2 کی ضرورت ہے وہ براؤزر پر مبنی ڈیش بورڈ چیٹ پین ہے (یہ POSIX PTY استعمال کرتا ہے — کلاسک CLI اور گیٹ وے دونوں مقامی طور پر چلتے ہیں)۔

-## API-کیز اکٹھی کرنے سے بچیں — Nous Portal
-
-ہرمیس آپ کے پسندیدہ پرووائیڈر کے ساتھ کام کرتا ہے — یہ چیز تبدیل نہیں ہو رہی۔ لیکن اگر آپ ماڈل، ویب سرچ، امیج جنریشن، TTS، اور کلاؤڈ براؤزر کے لیے پانچ الگ الگ API کیز جمع نہیں کرنا چاہتے، تو **[Nous Portal](https://portal.nousresearch.com)** ان سب کو ایک ہی سبسکرپشن کے تحت کور کرتا ہے:
-
-- **300+ ماڈلز** — ان میں سے کوئی بھی ماڈل `/model <name>` کے ذریعے منتخب کریں
-- **ٹول گیٹ وے (Tool Gateway)** — ویب سرچ (Firecrawl)، امیج جنریشن (FAL)، ٹیکسٹ ٹو سپیچ (OpenAI)، کلاؤڈ براؤزر (Browser Use)، یہ سب آپ کی سبسکرپشن کے ذریعے چلتے ہیں۔ کسی اضافی اکاؤنٹ کی ضرورت نہیں۔
-
-نئی انسٹالیشن کے بعد بس ایک کمانڈ کی ضرورت ہے:
-
-<div dir="ltr">
-
-```bash
-hermes setup --portal
-```
-
-</div>
-
-یہ آپ کو OAuth کے ذریعے لاگ ان کرواتا ہے، Nous کو آپ کا پرووائیڈر مقرر کرتا ہے، اور ٹول گیٹ وے کو آن کر دیتا ہے۔ `hermes portal info` کمانڈ استعمال کر کے آپ کسی بھی وقت چیک کر سکتے ہیں کہ کون کون سی سروسز منسلک ہیں۔ مکمل تفصیلات [Tool Gateway دستاویزات کے صفحے](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway) پر موجود ہیں۔
-
-آپ اب بھی کسی بھی ٹول کے لیے اپنی مرضی کی API کیز استعمال کر سکتے ہیں — گیٹ وے ہر سروس کے لیے الگ الگ کام کرتا ہے، ایسا نہیں کہ یا تو سب کچھ استعمال کریں یا کچھ بھی نہیں۔
-

-
-## CLI بمقابلہ میسجنگ فوری حوالہ
-
-ہرمیس کے دو بنیادی انٹر فیس ہیں: آپ ٹرمینل UI کو `hermes` کے ساتھ شروع کریں، یا گیٹ وے چلا کر اس کے ساتھ ٹیلی گرام، ڈسکارڈ، سلیک، واٹس ایپ، سگنل، یا ای میل کے ذریعے بات کریں۔ جب آپ کسی بات چیت میں ہوتے ہیں، تو بہت سی سلیش (slash) کمانڈز دونوں انٹرفیسز میں ایک جیسی ہوتی ہیں۔

-
-اگر آپ OpenClaw سے منتقل ہو رہے ہیں، تو ہرمیس آپ کی سیٹنگز، یادیں (memories)، مہارتیں (skills)، اور API کیز کو خود بخود امپورٹ کر سکتا ہے۔
-
-**پہلی بار سیٹ اپ کے دوران:** سیٹ اپ وزرڈ (`hermes setup`) خود بخود `~/.openclaw` کو پہچان لیتا ہے اور کنفیگریشن شروع ہونے سے پہلے مائیگریٹ (migrate) کرنے کا آپشن دیتا ہے۔
-
-**انسٹالیشن کے بعد کسی بھی وقت:**
-
-<div dir="ltr">
-
-```bash
-hermes claw migrate              # انٹرایکٹو مائیگریشن (مکمل پری سیٹ)
-hermes claw migrate --dry-run    # جائزہ لیں کہ کیا کیا مائیگریٹ ہوگا
-hermes claw migrate --preset user-data   # حساس معلومات (secrets) کے بغیر مائیگریٹ کریں
-hermes claw migrate --overwrite  # موجودہ متصادم فائلوں کو اوور رائٹ کریں
-```
-
-</div>
-
-جو چیزیں امپورٹ ہوتی ہیں:
-
-- **SOUL.md** — پرسونا (persona) فائل
-- **میموریز (Memories)** — MEMORY.md اور USER.md کی اندراجات
-- **مہارتیں (Skills)** — صارف کی بنائی گئی مہارتیں → `~/.hermes/skills/openclaw-imports/`
-- **کمانڈ الاؤ لسٹ (allowlist)** — منظوری کے پیٹرنز (approval patterns)
-- **میسجنگ سیٹنگز** — پلیٹ فارم کنفیگریشنز، اجازت یافتہ صارفین، ورکنگ ڈائریکٹری
-- **API کیز** — الاؤ لسٹ شدہ حساس معلومات (ٹیلی گرام، OpenRouter، OpenAI، Anthropic، ElevenLabs)
-- **TTS اثاثے** — ورک اسپیس کی آڈیو فائلیں
-- **ورک اسپیس کی ہدایات** — AGENTS.md (`--workspace-target` کے ساتھ)
-
-تمام آپشنز دیکھنے کے لیے `hermes claw migrate --help` استعمال کریں، یا انٹرایکٹو ایجنٹ کی مدد سے مائیگریٹ کرنے کے لیے `openclaw-migration` سکل کا استعمال کریں (جس میں ڈرائی رن (dry-run) پریویوز شامل ہیں)۔

-# Política de Seguridad de Hermes Agent
-
-Este documento describe el modelo de confianza de Hermes Agent, identifica el
-único límite de seguridad que el proyecto trata como estructural y define el
-alcance para los informes de vulnerabilidades.
-
-## 1. Reportar una Vulnerabilidad
-
-Reporta de forma privada a través de [GitHub Security Advisories](https://github.com/NousResearch/hermes-agent/security/advisories/new)
-o **security@nousresearch.com**. No abras issues públicos para
-vulnerabilidades de seguridad. **Hermes Agent no opera un programa de
-recompensas por errores.**
-
-Un informe útil incluye:
-
-- Una descripción concisa y evaluación de severidad.
-- El componente afectado, identificado por ruta de archivo y rango de líneas
-  (ej. `path/to/file.py:120-145`).
-- Detalles del entorno (`hermes version`, SHA del commit, SO, versión de Python).
-- Una reproducción contra `main` o el último release.
-- Una declaración de qué límite de confianza del §2 se cruza.
-
-Por favor lee el §2 y el §3 antes de enviar. Los informes que demuestren
-límites de una heurística en proceso que esta política no trate como un
-límite serán cerrados como fuera de alcance bajo el §3 — pero consulta el §3.2:
-siguen siendo bienvenidos como issues o pull requests regulares, simplemente no
-a través del canal de seguridad privado.
-
----
-
-## 2. Modelo de Confianza
-
-Hermes Agent es un agente personal de un solo inquilino. Su postura es
-por capas, y las capas no tienen el mismo peso. Los reportadores y
-operadores deben razonar sobre ellas en los mismos términos.
-
-### 2.1 Definiciones
-
-- **Proceso del agente.** El intérprete Python que ejecuta Hermes Agent,
-  incluyendo cualquier módulo Python que haya cargado (habilidades, plugins,
-  manejadores de hooks).
-- **Backend de terminal.** Un objetivo de ejecución conectado para la
-  herramienta `terminal()`. El predeterminado ejecuta comandos directamente en el host.
-  Otros backends ejecutan comandos dentro de un contenedor, sandbox en la nube o
-  host remoto.
-- **Superficie de entrada.** Cualquier canal a través del cual el contenido entra en el
-  contexto del agente: entrada del operador, fetches web, email, mensajes del gateway,
-  lecturas de archivos, respuestas del servidor MCP, resultados de herramientas.
-- **Envolvente de confianza.** El conjunto de recursos a los que un operador ha otorgado
-  implícitamente acceso a Hermes Agent al ejecutarlo — típicamente, todo lo que
-  la propia cuenta de usuario del operador puede alcanzar en el host.
-- **Postura.** Una declaración explícita en la documentación o código de Hermes Agent
-  sobre cómo una capa consumidora (adaptador, UI, escritor de archivos,
-  shell) debe tratar la salida del agente — ej. "el dashboard renderiza
-  la salida del agente como HTML inerte."
-
-### 2.2 El Límite: Aislamiento a Nivel de SO
-
-**El único límite de seguridad contra un LLM adversario es el
-sistema operativo.** Nada dentro del proceso del agente constituye
-contención — ni la puerta de aprobación, ni la redacción de salida, ni ningún
-escáner de patrones, ni ninguna lista de herramientas permitidas. Cualquier componente dentro
-del proceso que filtre la salida del LLM es una heurística operando sobre una
-cadena influenciada por el atacante, y esta política lo trata como tal.
-
-Hermes Agent admite dos posturas de aislamiento a nivel de SO. Abordan
-diferentes amenazas y un operador debe elegir deliberadamente.
-
-#### Aislamiento del backend de terminal
-
-Un backend de terminal no predeterminado ejecuta comandos de shell emitidos por el LLM
-dentro de un contenedor, host remoto o sandbox en la nube. Las herramientas de archivos
-(`read_file`, `write_file`, `patch`) también se ejecutan a través de este backend,
-ya que están implementadas sobre el contrato del shell — no pueden
-alcanzar rutas que el backend no exponga.
-
-Lo que confina: todo lo que el agente hace emitiendo operaciones de shell o
-de archivos. Lo que **no** confina: todo lo que el agente hace en su propio
-proceso Python. Eso incluye la herramienta de ejecución de código (lanzada como
-subproceso del host), subprocesos MCP (lanzados desde el entorno del agente),
-carga de plugins, despacho de hooks y carga de habilidades (todos importados en el
-intérprete del agente).
-
-El aislamiento del backend de terminal es la postura correcta cuando la preocupación es
-que el LLM emita comandos de shell destructivos o escrituras de herramientas de archivo no deseadas, y el
-operador es de confianza.
-
-#### Envoltura del proceso completo
-
-La envoltura del proceso completo ejecuta todo el árbol de procesos del agente dentro de un
-sandbox. Cada ruta de código — shell, ejecución de código, MCP, herramientas de archivos,
-plugins, hooks, carga de habilidades — está sujeta a la misma política de sistema de archivos,
-red, proceso e (donde sea aplicable) inferencia.
-
-Hermes Agent admite esto de dos maneras:
-
-- **La propia imagen Docker de Hermes Agent y la configuración de Compose.** Más
-  liviana; el agente se ejecuta en un contenedor estándar con montajes y
-  política de red configurados por el operador.
-- **[NVIDIA OpenShell](https://github.com/NVIDIA/OpenShell)**.
-  OpenShell proporciona sandboxes por sesión con política declarativa
-  a través de capas de sistema de archivos, red (egreso L7), proceso/syscall e
-  enrutamiento de inferencia. Las políticas de red e inferencia son
-  recargables en caliente. Las credenciales se inyectan desde un almacén de Proveedor
-  y nunca tocan el sistema de archivos del sandbox.
-
-Bajo una envoltura de proceso completo, las heurísticas en proceso de Hermes Agent
-(§2.4) funcionan como prevención de accidentes en capas sobre un límite real.
-Esta es la postura soportada cuando el agente ingiere contenido de superficies
-que el operador no controla — la web abierta, email entrante, canales de
-múltiples usuarios, servidores MCP no confiables — y para despliegues en
-producción o compartidos.
-
-Los operadores que ejecuten el backend local predeterminado con superficies de entrada
-no confiables, o que ejecuten un sandbox de backend de terminal esperando que contenga
-rutas de código que no pasan por el shell, están operando fuera de la postura de
-seguridad soportada.
-
-### 2.3 Alcance de Credenciales
-
-Hermes Agent filtra el entorno que pasa a sus componentes en proceso de
-menor confianza: subprocesos de shell, subprocesos MCP y el proceso hijo
-de ejecución de código. Las credenciales como las claves API del proveedor y los
-tokens del gateway se eliminan por defecto; las variables declaradas explícitamente
-por el operador o por una habilidad cargada se pasan.
-
-Esto reduce la exfiltración casual. No es contención. Cualquier
-componente que se ejecute dentro del proceso del agente (habilidades, plugins, manejadores
-de hooks) puede leer lo que el agente mismo puede leer, incluidas las
-credenciales en memoria. La mitigación contra un componente en proceso comprometido
-es la revisión del operador antes de instalar (§2.4, §2.5), no el
-saneamiento del entorno.
-
-### 2.4 Heurísticas en Proceso
-
-Los siguientes componentes filtran o advierten sobre el comportamiento del LLM. Son
-útiles. No son límites.
-
-- La **puerta de aprobación** detecta patrones de shell destructivos comunes
-  y le pide al operador confirmación antes de la ejecución. El shell es Turing-
-  completo; una lista de denegación sobre cadenas de shell es estructuralmente
-  incompleta. La puerta detecta errores en modo cooperativo, no salidas
-  adversariales.
-- **La redacción de salida** elimina patrones similares a secretos de la visualización.
-  Un productor de salida motivado la evitará.
-- **Skills Guard** escanea el contenido de habilidades instalables en busca de patrones
-  de inyección. Es una ayuda de revisión; el límite para habilidades de terceros
-  es la revisión del operador antes de instalar. Revisar una habilidad significa
-  leer su código Python y scripts, no solo su descripción SKILL.md —
-  las habilidades ejecutan Python arbitrario en el momento de importación.
-
-### 2.5 Modelo de Confianza de Plugins
-
-Los plugins se cargan en el proceso del agente y se ejecutan con todos los privilegios
-del agente: pueden leer las mismas credenciales, llamar a las mismas
-herramientas, registrar los mismos hooks e importar los mismos módulos que
-cualquier cosa incluida en el árbol. El límite para los plugins de terceros es
-la revisión del operador antes de instalar — la misma regla que las habilidades (§2.4),
-mencionado por separado porque los plugins son arquitectónicamente más pesados
-y a menudo incluyen sus propios servicios en segundo plano, oyentes de red
-y dependencias.
-
-Un plugin malicioso o con errores no es una vulnerabilidad en Hermes Agent
-en sí mismo. Los errores en la ruta de instalación o descubrimiento de plugins de Hermes Agent
-que impidan al operador ver lo que está instalando están en alcance bajo el §3.1.
-
-### 2.6 Superficies Externas
-
-Una **superficie externa** es cualquier canal fuera del proceso del agente local
-a través del cual un llamador puede despachar trabajo del agente, resolver
-aprobaciones o recibir salida del agente. Cada superficie tiene su propio
-modelo de autorización, pero las reglas a continuación se aplican uniformemente.
-
-**Superficies en Hermes Agent:**
-
-- **Adaptadores de plataforma del gateway.** Integraciones de mensajería en
-  `gateway/platforms/` (Telegram, Discord, Slack, email, SMS, etc.)
-  y adaptadores análogos incluidos como plugins.
-- **Superficies HTTP expuestas en red.** El adaptador del servidor API, el
-  plugin del dashboard, los endpoints HTTP del plugin kanban, y cualquier
-  otro plugin que vincule un socket de escucha.
-- **Adaptadores de Editor / IDE.** El adaptador ACP (`acp_adapter/`) e
-  integraciones equivalentes que aceptan solicitudes de un proceso cliente local.
-- **El gateway TUI (`tui_gateway/`).** Backend JSON-RPC para la
-  UI de terminal Ink, alcanzado a través de IPC local.
-
-**Reglas uniformes:**
-
-1. **Se requiere autorización en cada superficie que cruce un límite de confianza.** Para
-   superficies de mensajería y HTTP en red, el límite es la red: la autorización
-   significa una lista de llamadores permitidos configurada por el operador. Para superficies
-   de editor e IPC local (ACP, gateway TUI), el límite es la cuenta de usuario del host:
-   la autorización significa depender del control de acceso a nivel de SO (permisos
-   de archivos, vinculaciones solo a loopback) y no exponer la superficie más allá
-   del usuario local sin una capa de autenticación de red explícita.
-2. **Se requiere una lista de permitidos para cada adaptador de red habilitado.**
-   Los adaptadores deben rechazar despachar trabajo del agente, resolver
-   aprobaciones o transmitir salida hasta que se establezca una lista de permitidos. Las rutas
-   de código que fallan de forma abierta cuando no hay lista de permitidos configurada son errores de código en
-   alcance bajo el §3.1.
-3. **Los identificadores de sesión son manejadores de enrutamiento, no límites de autorización.**
-   Conocer el ID de sesión de otro llamador no otorga acceso a sus aprobaciones o salida;
-   la autorización siempre se vuelve a verificar contra la lista de permitidos (o equivalente
-   a nivel de SO).
-4. **Dentro del conjunto autorizado, todos los llamadores tienen la misma confianza.**
-   Hermes Agent no modela capacidades por llamador dentro de un único adaptador.
-   Los operadores que necesiten separación de capacidades deben ejecutar instancias
-   de agente separadas con listas de permitidos separadas.
-5. **Vincular una superficie solo local a una interfaz no-loopback es una decisión de
-   operador de emergencia (§3.2).** El dashboard y otros servidores HTTP de plugins
-   son predeterminados a loopback; exponerlos a través de `--host 0.0.0.0` o equivalente
-   hace que el fortalecimiento de exposición pública (§4) sea responsabilidad del operador.

-## 3. Alcance
-
-### 3.1 En Alcance
-
-- Escape de una postura de aislamiento a nivel de SO declarada (§2.2): una
-  ruta de código controlada por el atacante alcanzando estado que la postura
-  afirmó confinar.
-- Acceso no autorizado a superficie externa: un llamador fuera del conjunto de
-  autorización configurado (lista de permitidos, o equivalente a nivel de SO
-  para superficies de IPC local) despachando trabajo, recibiendo salida o
-  resolviendo aprobaciones (§2.6).
-- Exfiltración de credenciales: filtración de credenciales del operador o
-  material de autorización de sesión a un destino fuera del envolvente de
-  confianza, a través de un mecanismo que debería haberlo prevenido
-  (error de saneamiento de entorno, registro del adaptador, error de transporte
-  que vacía credenciales a un upstream, etc.).
-- Violaciones de la documentación del modelo de confianza: código que se comporta
-  contrariamente a lo que esta política, la propia documentación de Hermes Agent o
-  las expectativas razonables del operador predecirían — incluyendo casos donde
-  Hermes Agent ha documentado una postura sobre cómo su salida debe ser
-  renderizada por una capa consumidora (dashboard, adaptador de gateway,
-  escritor de archivos, shell) y una ruta de código rompe esa postura.
-
-### 3.2 Fuera de Alcance
-
-"Fuera de alcance" aquí significa "no es una vulnerabilidad de seguridad bajo esta
-política." No significa "no vale la pena reportarlo." Las mejoras a las
-heurísticas en proceso, ideas de fortalecimiento y correcciones de UX son bienvenidas como
-issues o pull requests regulares — la puerta de aprobación siempre puede detectar
-más patrones, la redacción puede volverse más inteligente, el comportamiento del adaptador
-puede apretarse siempre. Estos elementos simplemente no van a través del canal de
-divulgación privada y no reciben avisos.
-
-- **Bypasses de heurísticas en proceso (§2.4)** — bypasses de regex de la puerta de aprobación,
-  bypasses de redacción, bypasses de patrones de Skills Guard, e informes
-  análogos contra heurísticas futuras. Estos componentes no son límites;
-  vencerlos no es una vulnerabilidad bajo esta política.
-- **Inyección de prompts per se.** Hacer que el LLM emita salida inusual
-  — a través de contenido inyectado, alucinación, artefactos de entrenamiento,
-  o cualquier otra causa — no es en sí mismo una vulnerabilidad. "Logré
-  inyección de prompts" sin un resultado encadenado del §3.1 no es un informe
-  procesable bajo esta política.
-- **Consecuencias de una postura de aislamiento elegida.** Los informes de que
-  una ruta de código que opera dentro del alcance de su postura puede hacer lo que esa
-  postura permite no son vulnerabilidades. Ejemplos: herramientas de shell o archivos
-  que alcanzan estado del host bajo el backend local; subprocesos de ejecución de código
-  o MCP que alcanzan estado del host bajo aislamiento de backend de terminal que solo
-  sandboxea el shell; informes cuyas precondiciones requieren acceso de escritura preexistente
-  a archivos de configuración o credenciales propiedad del operador (esos ya están dentro
-  del envolvente de confianza).
-- **Configuraciones documentadas de emergencia.** Compensaciones seleccionadas por el operador
-  que deshabilitan explícitamente protecciones: `--insecure` y flags equivalentes
-  en el dashboard u otros componentes, aprobaciones deshabilitadas,
-  backend local en producción, perfiles de desarrollo que evitan
-  la seguridad de hermes-home, y similares. Los informes contra esas
-  configuraciones no son vulnerabilidades — eso es el trabajo del flag.
-- **Habilidades y plugins contribuidos por la comunidad.** Las habilidades de terceros
-  (incluyendo el repositorio de habilidades de la comunidad) y los plugins de terceros
-  están en la superficie de revisión del operador, no en la superficie de confianza de Hermes Agent
-  (§2.4, §2.5). Una habilidad o plugin que haga algo
-  malicioso es el modo de falla esperado de uno que no fue
-  revisado, no una vulnerabilidad en Hermes Agent. Los errores en la ruta de
-  instalación de habilidades o plugins de Hermes Agent que impidan al
-  operador ver lo que está instalando están en alcance bajo el §3.1.
-- **Exposición pública sin controles externos.** Exponer el
-  gateway o la API a la internet pública sin autenticación,
-  VPN o firewall.
-- **Restricciones de lectura/escritura a nivel de herramienta en una postura donde el shell está
-  permitido.** Si una ruta es alcanzable a través de la herramienta terminal, los informes
-  de que otras herramientas de archivos pueden alcanzarla no añaden nada.
-
----
-
-## 4. Fortalecimiento del Despliegue
-
-La decisión de fortalecimiento más importante es hacer coincidir el aislamiento
-(§2.2) con la confianza del contenido que el agente ingerirá. Más allá de eso:
-
-- Ejecuta el agente como usuario no-root. La imagen de contenedor proporcionada
-  hace esto por defecto.
-- Mantén las credenciales en el archivo de credenciales del operador con permisos
-  estrictos, nunca en la configuración principal, nunca en control de versiones.
-  Bajo OpenShell, usa el almacén de Proveedores en lugar de un archivo de
-  credenciales en disco.
-- No expongas el gateway o la API a la internet pública sin
-  VPN, Tailscale o protección de firewall. Bajo OpenShell, usa la
-  capa de política de red para restringir el egreso.
-- Configura una lista de llamadores permitidos para cada adaptador de red expuesto
-  que habilites (§2.6).
-- Revisa las habilidades y plugins de terceros antes de instalar (§2.4,
-  §2.5). Para las habilidades, esto significa leer el Python y los scripts,
-  no solo SKILL.md. Los informes de Skills Guard y el registro de auditoría
-  de instalación son la superficie de revisión.
-- Hermes Agent incluye guardias de cadena de suministro para lanzamientos de servidores
-  MCP y para cambios de dependencias / paquetes incluidos en CI; consulta
-  `CONTRIBUTING.es.md` para más detalles.

-
-## 5. Divulgación
-
-- **Ventana de divulgación coordinada:** 90 días desde el informe, o hasta que se
-  publique una corrección, lo que ocurra primero.
-- **Canal:** el hilo GHSA o correspondencia por email con

-"""Coding-context awareness — base Hermes, every interactive surface.
-
-When the user runs Hermes inside a code workspace (CLI, TUI, desktop app, or an
-editor over ACP), Hermes shifts into a **coding posture**. This module is the
-single place that decides whether we're in that posture and what it implies,
-so the rest of the codebase never re-derives "are we coding?" on its own.
-
-Architecture — one seam, many consumers
-----------------------------------------
-The posture is modelled as a frozen :class:`RuntimeMode` selected from a small
-:class:`ContextProfile` registry (today: ``coding`` and ``general``). A profile
-is *data* — it declares the toolset to collapse to, the operating brief to
-inject, and hints for other domains (model routing, memory, subagents). Every
-domain reads the same resolved object instead of probing git/config itself:
-
-  * **System prompt** — ``RuntimeMode.system_blocks()`` → the operating brief +
-    a live git/workspace snapshot (``agent/system_prompt.py``).
-  * **Toolset** — ``RuntimeMode.toolset_selection()`` → the ``coding`` toolset
-    plus the user's enabled MCP servers (``cli.py`` / ``tui_gateway``). Only
-    under the opt-in ``focus`` mode: the default posture is prompt-only and
-    never touches the user's configured toolsets (toolsets like messaging /
-    smart-home / music are off-by-default anyway, and someone who explicitly
-    enabled image-gen or Spotify shouldn't lose it for being in a git repo).
-  * **Delegation** — subagents inherit the parent's toolset and run through the
-    same prompt builder, so the coding posture propagates to children for free.
-  * **Model / memory / compression** — declared on the profile
-    (``model_hint``, ``memory_policy``) as the extension seam; consumers read
-    ``mode.profile`` rather than re-deciding.
-
-Cache safety
-------------
-The mode is resolved **once** and is immutable. The workspace snapshot is built
-once at prompt-build time and baked into the *stable* system-prompt tier — never
-re-probed per turn (that would shatter the prompt cache). Branch and dirty state
-drift mid-session, so the brief tells the model to re-check with ``git`` before
-acting on the snapshot. A ``/coding`` flip therefore only takes effect next
-session (deferred), the same contract as ``/skills install`` vs ``--now``.
-
-Activation (config ``agent.coding_context``):
-
-  * ``auto`` (default) — posture (brief + snapshot) on an interactive coding
-    surface sitting in a code workspace (git repo or recognised project root).
-    Prompt-only; toolsets and the skill index untouched.
-  * ``focus`` — like ``auto``, but additionally collapses the toolset to the
-    ``coding`` set + enabled MCP servers and demotes non-coding skill
-    categories to names-only in the prompt's skill index (no skill is ever
-    hidden). Explicit opt-in for a lean schema.
-  * ``on`` — force the posture anywhere (incl. non-workspaces). Prompt-only.
-  * ``off`` — disable entirely.

-Parses x-nous-credits-* (and optional x-nous-tool-pool-*) headers from
-inference responses into a validated CreditsState dataclass.  Provides
-depletion detection (paid_access), subscription-cap used_fraction, and
-warn-once schema-version gating.  This is the hardened parser used by all
-live consumers (run_agent, tui_gateway) — not a dev-only shim.
-
-Header schema (x-nous-credits-* family):
-    x-nous-credits-version                    contract/schema version
-    x-nous-credits-remaining-micros           total remaining balance (micros)
-    x-nous-credits-remaining-usd              same, formatted USD string
-    x-nous-credits-subscription-micros        subscription balance (SIGNED; may be negative/debt)
-    x-nous-credits-subscription-usd           same, formatted USD string
-    x-nous-credits-subscription-limit-micros  subscription cap (PAIRED/optional)
-    x-nous-credits-subscription-limit-usd     same, formatted USD string (PAIRED/optional)
-    x-nous-credits-rollover-micros            rolled-over balance (micros)
-    x-nous-credits-purchased-micros           purchased balance (micros)

-    x-nous-credits-disabled-reason            reason string (header omitted when null)
-    x-nous-credits-as-of-ms                   server-side timestamp (ms epoch)

+"""OpenAI-compatible facade that talks to Google's Cloud Code Assist backend.
+
+This adapter lets Hermes use the ``google-gemini-cli`` provider as if it were
+a standard OpenAI-shaped chat completion endpoint, while the underlying HTTP
+traffic goes to ``cloudcode-pa.googleapis.com/v1internal:{generateContent,
+streamGenerateContent}`` with a Bearer access token obtained via OAuth PKCE.
+
+Architecture
+------------
+- ``GeminiCloudCodeClient`` exposes ``.chat.completions.create(**kwargs)``
+  mirroring the subset of the OpenAI SDK that ``run_agent.py`` uses.
+- Incoming OpenAI ``messages[]`` / ``tools[]`` / ``tool_choice`` are translated
+  to Gemini's native ``contents[]`` / ``tools[].functionDeclarations`` /
+  ``toolConfig`` / ``systemInstruction`` shape.
+- The request body is wrapped ``{project, model, user_prompt_id, request}``
+  per Code Assist API expectations.
+- Responses (``candidates[].content.parts[]``) are converted back to
+  OpenAI ``choices[0].message`` shape with ``content`` + ``tool_calls``.
+- Streaming uses SSE (``?alt=sse``) and yields OpenAI-shaped delta chunks.
+
+Attribution
+-----------
+Translation semantics follow jenslys/opencode-gemini-auth (MIT) and the public
+Gemini API docs. Request envelope shape
+(``{project, model, user_prompt_id, request}``) is documented nowhere; it is
+reverse-engineered from the opencode-gemini-auth and clawdbot implementations.

+"""Google Code Assist API client — project discovery, onboarding, quota.
+
+The Code Assist API powers Google's official gemini-cli. It sits at
+``cloudcode-pa.googleapis.com`` and provides:
+
+- Free tier access (generous daily quota) for personal Google accounts
+- Paid tier access via GCP projects with billing / Workspace / Standard / Enterprise
+
+This module handles the control-plane dance needed before inference:
+
+1. ``load_code_assist()`` — probe the user's account to learn what tier they're on
+   and whether a ``cloudaicompanionProject`` is already assigned.
+2. ``onboard_user()`` — if the user hasn't been onboarded yet (new account, fresh
+   free tier, etc.), call this with the chosen tier + project id. Supports LRO
+   polling for slow provisioning.
+3. ``retrieve_user_quota()`` — fetch the ``buckets[]`` array showing remaining
+   quota per model, used by the ``/gquota`` slash command.
+
+VPC-SC handling: enterprise accounts under a VPC Service Controls perimeter
+will get ``SECURITY_POLICY_VIOLATED`` on ``load_code_assist``. We catch this
+and force the account to ``standard-tier`` so the call chain still succeeds.
+
+Derived from opencode-gemini-auth (MIT) and clawdbot/extensions/google. The
+request/response shapes are specific to Google's internal Code Assist API,
+documented nowhere public — we copy them from the reference implementations.

-``/learn`` is open-ended. The user can point it at anything they can describe:
-a directory of code, an API doc URL, a workflow they just walked the agent
-through in this conversation, or pasted notes. This module builds ONE prompt
-that instructs the live agent to:
-
-  1. Gather the sources the user named, using the tools it already has
-     (``read_file`` / ``search_files`` for dirs, ``web_extract`` for URLs, the
-     current conversation for "what I just did", the user's text for pasted
-     material).
-  2. Author a single ``SKILL.md`` via ``skill_manage`` that follows the Hermes
-     skill-authoring standards (description <=60 chars, the modern section
-     order, Hermes-tool framing, no invented commands).
-
-There is no separate distillation engine and no model-tool footprint: the
-agent does the work with its existing toolset, so this works identically on
-local, Docker, and remote terminal backends. Every surface (CLI ``/learn``,
-gateway ``/learn``, the dashboard "Learn a skill" panel) calls
-:func:`build_learn_prompt` and feeds the result to the agent as a normal turn.

-_AUTHORING_STANDARDS = """\
-Follow the Hermes skill-authoring standards exactly. These are the same
-HARDLINE rules a maintainer enforces in review:
-
-Frontmatter:
-- name: lowercase-hyphenated, <=64 chars, no spaces.
-- description: ONE sentence, **<=60 characters**, ends with a period. State the
-  capability, not the implementation. No marketing words (powerful,
-  comprehensive, seamless, advanced, robust). Do NOT repeat the skill name. If
-  the description contains a colon, wrap the whole value in double quotes.
-  This is the most-violated rule and it is NOT cosmetic: the system-prompt
-  skill index truncates the description to 60 chars and loads it every
-  session, so anything past char 60 is silently cut and never routes. After
-  you write the description, COUNT the characters; if it is over 60, cut it
-  down before saving — do not ship a sentence and hope.
-    Good (<=60): `Search arXiv papers by keyword, author, or ID.`
-    Bad (123):   `A comprehensive skill that lets the agent search arXiv for
-                  academic papers using keywords, authors, and categories.`
-- version: 0.1.0
-- author: always the literal value `Hermes`. NEVER fill it from the host
-  environment — the OS/login username (e.g. the `user=` line in your
-  environment hints), git config, or any identity you can probe must not be
-  written. Skills get shared and published, so an environment-derived name is
-  a privacy leak the user never opted into; the skill names itself as Hermes.
-- platforms: declare `[macos]`, `[linux]`, and/or `[windows]` IF the skill
-  uses OS-bound primitives (osascript/apt/systemctl => the matching OS; /proc,
-  os.setsid, signal.SIGKILL => linux; fcntl/termios => POSIX). Prefer fixing it
-  cross-platform first (tempfile.gettempdir(), pathlib.Path, psutil); gate only
-  when the dependency is genuinely platform-bound. Omit the field for portable
-  skills.
-- metadata.hermes.tags: a few Capitalized, Relevant, Tags.
-
-Body section order (omit a section only if it genuinely has no content):
-1. "# <Human Title>" then a 2-3 sentence intro: what it does, what it does NOT
-   do, and the key dependency stance (e.g. "stdlib only").
-2. "## When to Use" — bullet list of concrete trigger phrases.
-3. "## Prerequisites" — exact env vars, install steps, credentials.
-4. "## How to Run" — the canonical invocation, framed through Hermes tools.
-5. "## Quick Reference" — a flat command/endpoint list, no narration.
-6. "## Procedure" — numbered steps with copy-paste-exact commands.
-7. "## Pitfalls" — known limits, rate limits, things that look broken but aren't.
-8. "## Verification" — a single command/check that proves the skill worked.
-
-Hermes-tool framing (this is what makes it a skill, not shell docs):
-- Frame running scripts as "invoke through the `terminal` tool".
-- Reference Hermes tools by name in backticks: `terminal`, `read_file`,
-  `write_file`, `search_files`, `patch`, `web_extract`, `web_search`,
-  `vision_analyze`, `browser_navigate`, `delegate_task`, `image_generate`,
-  `text_to_speech`, `cronjob`, `memory`, `skill_view`, `execute_code`.
-- Do NOT name shell utilities the agent already has wrapped: say `read_file`
-  not cat/head/tail, `search_files` not grep/rg/find/ls, `patch` not sed/awk,
-  `web_extract` not curl-to-scrape, `write_file` not echo>file or heredocs.
-- Third-party CLIs (ffmpeg, gh, an SDK) are fine inside a script file, but the
-  prose still frames them as "invoke through the `terminal` tool". If the
-  skill needs an MCP server, name it and document its setup in Prerequisites.
-
-Quality bar:
-- Prefer exact commands, endpoint URLs, function signatures, and config keys
-  that appear VERBATIM in the source. NEVER invent flags, paths, or APIs — if
-  you didn't see it in the source, don't write it.
-- Keep it tight and scannable: ~100 lines for a simple skill, ~200 for a
-  complex one. Don't re-paste the source docs.
-- Don't write a router/index/hub skill that only points at other skills.
-- Larger scripts/parsers belong in a `scripts/` file (add via
-  `skill_manage` write_file), referenced from SKILL.md by relative path — not
-  inlined for the agent to re-type every run. References go in `references/`,
-  templates in `templates/`."""
