-# 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.

-
-### 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

-### 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.

-
-### 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
-name: mitema
-description: Breve descripción del tema
-
-colors:
-  banner_border: "#HEX"
-  banner_title: "#HEX"
-  banner_accent: "#HEX"
-  banner_dim: "#HEX"
-  banner_text: "#HEX"
-  response_border: "#HEX"
-
-spinner:
-  waiting_faces: ["(⚔)", "(⛨)"]
-  thinking_faces: ["(⚔)", "(⌁)"]
-  thinking_verbs: ["forjando", "planeando"]
-
-branding:
-  agent_name: "Mi Agente"
-  welcome: "Mensaje de bienvenida"
-  response_label: " ⚔ Agente "
-  prompt_symbol: "⚔"
-
-tool_prefix: "╎"
-```
-
-Todos los campos son opcionales — los valores faltantes se heredan de la skin predeterminada.
-
-**Opción B: Skin integrada**
-
-Añade al dict `_BUILTIN_SKINS` en `hermes_cli/skin_engine.py`. Usa el mismo esquema que arriba pero como dict de Python.
-
-**Activar:**
-- CLI: `/skin mitema` o establece `display.skin: mitema` en config.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.

-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>"

-- **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.

-- **For larger work**, comment on the issue to signal you're working on it, so others don't start the same thing.

-### 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.

-**El agente de IA con mejora continua creado por [Nous Research](https://nousresearch.com).** Es el único agente con un bucle de aprendizaje integrado: crea habilidades a partir de la experiencia, las mejora durante el uso, se impulsa a sí mismo a persistir el conocimiento, busca en sus propias conversaciones pasadas y construye un modelo cada vez más profundo de quién eres a lo largo de las sesiones. Ejecútalo en un VPS de $5, un clúster de GPUs o infraestructura sin servidor que cuesta casi nada cuando está inactivo. No está atado a tu laptop — habla con él desde Telegram mientras trabaja en una VM en la nube.
-
-Usa cualquier modelo que quieras — [Nous Portal](https://portal.nousresearch.com), [OpenRouter](https://openrouter.ai) (más de 200 modelos), [NovitaAI](https://novita.ai), [NVIDIA NIM](https://build.nvidia.com) (Nemotron), [Xiaomi MiMo](https://platform.xiaomimimo.com), [z.ai/GLM](https://z.ai), [Kimi/Moonshot](https://platform.moonshot.ai), [MiniMax](https://www.minimax.io), [Hugging Face](https://huggingface.co), OpenAI, o tu propio endpoint. Cambia con `hermes model` — sin cambios de código, sin dependencias.

-## 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.

-## Migración desde OpenClaw
-
-Si vienes de OpenClaw, Hermes puede importar automáticamente tu configuración, memorias, habilidades y claves API.
-
-**Durante la configuración inicial:** El asistente de configuración (`hermes setup`) detecta automáticamente `~/.openclaw` y ofrece migrar antes de que comience la configuración.
-
-**En cualquier momento después de instalar:**
-
-```bash
-hermes claw migrate              # Migración interactiva (preset completo)
-hermes claw migrate --dry-run    # Vista previa de qué se migraría
-hermes claw migrate --preset user-data   # Migrar sin secretos
-hermes claw migrate --overwrite  # Sobreescribir conflictos existentes
-```
-
-Qué se importa:
-
-- **SOUL.md** — archivo de personalidad
-- **Memorias** — entradas de MEMORY.md y USER.md
-- **Habilidades** — habilidades creadas por el usuario → `~/.hermes/skills/openclaw-imports/`
-- **Lista de comandos permitidos** — patrones de aprobación
-- **Configuración de mensajería** — configuración de plataformas, usuarios permitidos, directorio de trabajo
-- **Claves API** — secretos en lista de permitidos (Telegram, OpenRouter, OpenAI, Anthropic, ElevenLabs)
-- **Assets de TTS** — archivos de audio del espacio de trabajo
-- **Instrucciones del espacio de trabajo** — AGENTS.md (con `--workspace-target`)
-
-Consulta `hermes claw migrate --help` para todas las opciones, o usa la habilidad `openclaw-migration` para una migración guiada interactiva por el agente con vistas previas de dry-run.

-### 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).

-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

-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
-  security@nousresearch.com.
-- **Crédito:** los reportadores reciben crédito en las notas de versión a menos que
-  se solicite anonimato.

-"""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.

+"""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.

-# one tool call per turn multiplies the number of round-trips — and therefore

-"""Profile-scoped credential resolution for multi-profile gateway multiplexing.
-
-The multiplexing gateway serves many profiles from one process. Each profile
-has its own ``.env`` with its own provider keys and platform tokens, so we
-**cannot** union them into the process-global ``os.environ`` (that would leak
-profile A's keys to profile B's turns, and to every subprocess spawned with
-``env=dict(os.environ)``).
-
-This module provides a fail-closed, context-local secret scope:
-
-- ``set_secret_scope(mapping)`` installs the active profile's secrets for the
-  current task (a contextvar, so it propagates into the agent's worker thread
-  via ``copy_context()`` exactly like the HERMES_HOME override).
-- ``get_secret(name)`` reads from that scope. When multiplexing is **active**
-  and no scope is set, it RAISES rather than silently falling back to
-  ``os.environ`` — an un-migrated or newly-added call site fails loud at that
-  exact line instead of leaking another profile's value. When multiplexing is
-  **off** (the default), it transparently reads ``os.environ`` so the
-  single-profile gateway and every non-gateway caller behave exactly as before.

 ### How it works
 
-The packaged app ships the Electron shell and a native React chat surface. On first launch it can install the Hermes Agent runtime into `HERMES_HOME` (`~/.hermes`, or `%LOCALAPPDATA%\hermes` on Windows) — the **same layout a CLI install uses**, so the two are interchangeable. Backend resolution first honours `HERMES_DESKTOP_HERMES_ROOT`, then a completed managed install, then a probed `hermes` on `PATH` (unless `HERMES_DESKTOP_IGNORE_EXISTING=1` is set), and finally an explicit `HERMES_DESKTOP_HERMES` command override for packagers/troubleshooting. The renderer (React, in `src/`) talks to a `hermes dashboard` backend over the `tui_gateway`/dashboard APIs and reuses the agent runtime rather than embedding `hermes --tui`. The install, backend-resolution, and self-update logic all live in `electron/main.cjs`.
