Miguel Ángel 37370e1e7d fix(cli): set GIT_CLONE_PROTECTION_ACTIVE=0 for skills (GH #316) (#328) 
## Summary

Fixes #316 — `hyperframes skills` (and `npx skills add heygen-com/hyperframes`) fails with:

```
■  Failed to clone repository
fatal: active \`post-checkout\` hook found during \`git clone\`
└  Installation failed
```

## Root cause

Two layers stacked:

1. **Git 2.45+ refuses to execute hooks during `git clone` by default.** The opt-in is `GIT_CLONE_PROTECTION_ACTIVE=0` — the env-var name is intentionally explicit about the trade-off.
2. **Users who ran `git lfs install` globally have a post-checkout hook registered at `core.hooksPath`.** When the upstream `skills` CLI shells out to `git clone` to fetch a repo's `skills/` directory, git detects the user's LFS hook and aborts.

The check fires for **any repo**, regardless of whether the cloned repo uses LFS itself — it's protection against the user's own hooks, not the repo's content. Users who have git-lfs installed (very common) hit this for every clone the `skills` CLI does.

## The fix

`hyperframes skills` wraps `npx skills add`. The wrapper now sets `GIT_CLONE_PROTECTION_ACTIVE=0` on the spawned child's env via a single helper (`gitCloneFriendlyEnv`) with a docstring at the call site explaining exactly why. The rest of `process.env` is preserved — proxy settings, extra CA certs, locale, etc. stay untouched.

## What this fix doesn't do (deliberately)

This is the **code-path-we-own** fix. The deeper root cause is that the upstream `skills` CLI (vercel-labs/skills) should set this env var when it shells out to `git clone`. That would fix the bug for every user invoking `skills` directly — not just those who route through our wrapper. An upstream issue should be opened separately; not landing it as part of this PR.

## Users who call `npx skills add` directly

Documented in the new troubleshooting subsection: set the env var manually.

```bash
GIT_CLONE_PROTECTION_ACTIVE=0 npx skills add heygen-com/hyperframes
```

## Tests

`packages/cli/src/commands/skills.test.ts` — 2 cases:
- Every spawned child has `GIT_CLONE_PROTECTION_ACTIVE=0`
- The rest of `process.env` is preserved (not a wiped env)

Uses `vi.mock` on `node:child_process` because ESM doesn't allow live-module `vi.spyOn` on re-exported bindings.

## Docs

`docs/packages/cli.mdx` — new **Troubleshooting** subsection under the `skills` command. Explains both the automatic fix (`hyperframes skills` users are already covered) and the manual workaround (`npx skills add …` users).

## Closes

- #316

Dylanwoo 64e3735100 fix(cli): doctor shows platform-correct install hints (#319) 
The "FFmpeg not found" hint was hardcoded to `sudo apt install ffmpeg`
for any non-macOS platform — Windows users would see an apt command that
doesn't exist on their system, and Red Hat / Arch users got the wrong
package manager too.

`getFFmpegInstallHint()` already exists in browser/ffmpeg.ts (and is
already used by render.ts) and handles darwin / linux / win32 correctly.
Use it here too.

Also rewrite checkFFprobe:
- it previously used `which ffprobe` which is not available on Windows
  (cmd uses `where`), so on Windows the check always reported "Not
  found" even when ffprobe was on PATH
- run `ffprobe -version` directly instead, which works cross-platform
  whenever ffprobe is resolvable on PATH, and surfaces the version
  string in the same style as the FFmpeg check

Dylan woo 143af6aec3 feat(cli): add --json output to doctor 
`doctor` is one of the first commands users and agents run when something
is off — remote bug reports (e.g. #294, #316, #317) typically include a
doctor screenshot, which is painful to parse programmatically.

Every other CLI command that reports state already supports `--json`
(info, lint, compositions, catalog, benchmark, validate, capture). This
brings `doctor` in line with that convention so:

- CI pipelines can gate on `hyperframes doctor --json` (exit 1 on
  failure) without scraping terminal output
- AI agents consuming telemetry / diagnostic data get structured input
- Bug report tooling can attach machine-readable doctor output

Schema:

    {
      "ok": boolean,
      "platform": "darwin" | "linux" | "win32",
      "arch": "arm64" | "x64" | ...,
      "checks": [
        { "name": "FFmpeg", "ok": true, "detail": "ffmpeg version 8.1 …" },
        { "name": "Docker", "ok": false, "detail": "Not found",
          "hint": "https://docs.docker.com/get-docker/" }
      ],
      "_meta": { "version", "latestVersion", "updateAvailable" }
    }

Uses the existing `withMeta()` helper so the `_meta` envelope matches
other `--json` commands. Human output format is unchanged.

Miguel Ángel e4cfcd3f61 fix(cli): serialize port-availability probes (#309) (#310) 
Closes #309. Full credit to @gigadeniga for the diagnosis — the root cause + proposed fix in that issue are exactly what landed here.

## The bug

\`npx hyperframes preview\` failed deterministically on Crostini (ChromeOS Linux) with \`Ports 3002–3101 are all in use\`, even when nothing was actually listening on any of them.

## Why

\`testPortOnAllHosts\` ran four probes in parallel:

\`\`\`ts
const hosts = ["127.0.0.1", "0.0.0.0", "::1", "::"];
const results = await Promise.all(hosts.map((h) => isPortAvailableOnHost(port, h)));
\`\`\`

Each probe binds a socket and then calls \`server.close()\`. Close is async — the socket stays open until its callback fires on the next event-loop tick. While it's open, the wildcard binds (\`0.0.0.0\`, \`::\`) that include the loopback address race the still-open loopback socket and return \`EADDRINUSE\` spuriously. On Crostini this happens 100% of the time; other Linux configs hit it intermittently; macOS is less predictable. Net effect: every port in the 100-port scan range appears busy and the preview refuses to start.

Reproduces on any Linux box with the standalone snippet from the issue:

\`\`\`
127.0.0.1: OK
0.0.0.0: EADDRINUSE   ← false positive
::1: OK
::: EADDRINUSE        ← false positive
\`\`\`

## Fix

Serialize the probes. Each socket is fully closed before the next opens, eliminating the race window entirely.

\`\`\`ts
for (const host of hosts) {
  const available = await isPortAvailableOnHost(port, host);
  if (!available) return false;
}
return true;
\`\`\`

Kept the four-host check rather than collapsing to just \`0.0.0.0\` + \`::\` — the multi-host coverage is load-bearing for the devbox / SSH-forwarding case where a port is free on loopback but held on the wildcard. Sequentializing is the smaller, less-behaviourally-affecting fix.

## Regression tests

\`packages/cli/src/server/portUtils.test.ts\` — three cases binding real sockets, no mocks:

- **Returns true for a genuinely free port** — directly reproduces the Crostini bug; would fail on Linux against the parallel implementation.
- **Returns false when the port is occupied on \`0.0.0.0\`** — confirms the multi-host check still catches the devbox scenario.
- **Releases each probe socket before the next run** — two back-to-back calls for the same free port both return true, pinning the sequential contract against future refactors that might try to reparallelize for perf.

## Test plan

- [x] \`bunx vitest run packages/cli/src/server/portUtils.test.ts\` — 3/3 pass
- [x] Full CLI suite — 109/109 pass
- [x] \`tsc --noEmit\` clean

## Notes

- Independent of any version bump; ship whenever.
- Probing 4 hosts serially adds at most ~tens of milliseconds per port on the scan (binds are very fast on loopback). The worst-case cost shows up when the first port in the range is free — previously 1 parallel round-trip, now 4 sequential — and it's imperceptible (\`preview\` bind is a one-time startup cost, not a hot path).

ularkim de5b53c08b feat(capture): switch Gemini 2.5 Flash → 3.1 Flash Lite 
Gemini 3.1 Flash Lite Preview: 2.5x faster TTFT, 45% faster output,
slightly cheaper ($0.25/M vs $0.30/M input), near-2.5-Flash quality.
Descriptions are actually more detailed in testing.
 2026-04-16 22:58:50 -04:00
ularkim a77a6cbbf7 fix: double-audio bug + lint rules + docs guide + capture improvements 
Double-audio bug fix:
- scaffolding.ts: stop writing index.html in captures/ (root cause —
  runtime discovered scaffold + real index.html as two compositions)
- New lint rule: multiple_root_compositions — errors if >1 root HTML
- New lint rule: duplicate_audio_track — warns on overlapping audio

Capture improvements (from testing 30+ websites):
- Catalog runs BEFORE extractHtml (which mutates DOM — converts img src
  to data URLs). HeyKuba: 2 images → 78.
- networkidle2 instead of networkidle0 (unblocks SPAs with WebSockets)
- Lazy-load image wait, CSS background-image cataloging
- SVG naming from class/id/parent (not just aria-label)
- Gemini batch 5→20, pause 12s→2s, maxOutputTokens 300→500
- Asset descriptions sorted: captioned first

Docs:
- New guide: guides/website-to-video.mdx (full tutorial)
- CLI docs: added capture and snapshot commands
- docs.json: website-to-video in Guides nav

Ular KimsanovandClaude Opus 4.6 87f4c77e2f feat: website capture pipeline + 7-step video production skill (#284) 
* feat(cli): add website capture with AI-powered DESIGN.md generation

Adds `hyperframes capture <url>` command that extracts a complete design
system from any website, producing AI-agent-ready output:

- Full-page screenshot (lazy-load aware, nav at top)
- AI-generated DESIGN.md via Claude API (colors, typography, elevation,
  components, do's/don'ts) with programmatic asset catalog (136+ assets
  with HTML context annotations like img[src], css url(), link[rel=preload])
- CSS-purged compositions (87% size reduction via PurgeCSS)
- HTML-prettified compositions (one-tag-per-line for AI readability)
- CLAUDE.md + .cursorrules auto-generated for AI agent instructions
- Asset deduplication (srcset variants) and tracking pixel filtering

* feat(cli): add gemini 3.1 pro, playwright screenshots, replica refinement

- switch to gemini 3.1 pro (gemini-3.1-pro-preview) with claude fallback
- playwright for full-page screenshots (fixes puppeteer gradient/fixed bugs)
- replica refinement loop: generate, screenshot, compare, fix
- extract inline svgs (50 max, 10kb each) to assets/svgs/
- extract visible text in dom order for content accuracy
- detect js libraries (gsap, three.js, scrolltrigger) via globals
- improved asset catalog grouping and naming
- reverse-engineered aura system prompt documentation
- comprehensive session handoff doc

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update session handoff with slack research findings

- key finding: team already wants DESIGN.md integration (James, Bin, Vance)
- skills quality matters enormously - must invoke /hyperframes-compose
- eval infrastructure exists (Abhay's dashboards, Teodora's 78-criteria guide)
- templates at templates/ need study before finalizing skill
- session handoff updated with critical next steps

* refactor(cli): simplify capture pipeline, remove replica generator

* feat(capture): add Lottie detection and WebGL shader extraction

Captures Lottie animations via network interception and WebGL shader
source via gl.shaderSource hooking during site crawl. Updates
website-to-hyperframes skill with asset planning guidance, Lottie/shader
reading instructions, and stronger creative direction for scene planning.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* refactor(capture): clean pipeline + shader-first creative workflow

Capture pipeline:
- Remove dead deps (puppeteer-extra, stealth plugin, duplicate devDeps)
- Remove duplicate generateAgentPrompt() call (first lied about DESIGN.md)
- Remove dead canvas-to-image code in htmlExtractor (post canvas removal)
- Parallelize image downloads (batches of 5 via Promise.allSettled)
- Fix pre-existing TS error (match[1] guard in font downloader)
- Default capture output to captures/<hostname>

Skill creative overhaul:
- Add shader transition selection to creative director step (Step 4)
- Add shader wiring instructions to engineer step (Step 5)
- Replace 4-line energy modifiers with visual vocabulary table
- Strip rigid scene-by-scene templates from video-recipes.md
- Strip example fill data from scene plan tables
- Add "read transition refs before planning" instruction
- Add creative ambition language ("how the hell did they make this")

* docs: add implementation plan for skill architecture redesign

13-task plan covering: capture pipeline cleanup (remove AI generation,
fix colors to HEX, add asset descriptions, shader-ready scaffold),
skill restructuring (4 phases with artifact gates), and compose skill
Visual Identity Gate upgrade.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Fix __GSAP_TIMELINE reference to __timelines

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(capture): regex double-escape + simplify scaffold + fix asset descriptions

- Double-escape regex in tokenExtractor template literal (\s→\\s, \d→\\d, \(→\\()
  so browser receives valid regex patterns via page.evaluate()
- Simplify index.html scaffold: scene slots + audio + timeline + comment pointing
  to shader-setup.md reference (no broken inline shader boilerplate)
- Fix asset descriptions: use CatalogedAsset.contexts/notes instead of
  nonexistent htmlContext field

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: code review — 16 bugs, 7-step skill rewrite, cleanup

Code fixes:
- snapshot.ts: path traversal guard, browser leak (try/finally), div-by-zero
  for --frames 1, port bind error handling, rAF-based render settle
- index.ts: remove invalid thinkingConfig for gemini-2.5-flash, fix Gemini
  batch/rate-limit comments, fix video preview viewport y-coordinate
- tokenExtractor.ts: remove dead seen[si] dedup code
- gsap.ts: index ALL classes for inline-style transform conflict detection

Skill architecture rewrite (4-phase → 7-step):
- Replace phase-1 through phase-4 with step-1 through step-7
- Add techniques.md (10 visual techniques with code patterns)
- Fix /hyperframes-compose → /hyperframes (skill doesn't exist)
- Fix captures/arc-browser reference → shader-setup.md (file doesn't exist)
- Fix step-7 hardcoded captures/stripe path
- Document Gemini API free/paid rate limits in step-1

Cleanup:
- CLAUDE.md: restore from Stripe-capture overwrite, update 4-phase → 7-step
- .gitignore: add PR #267 skills (hyperframes-animation-map, hyperframes-contrast)
- Delete old phase-*.md, animation-recreation.md, tts-integration.md

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: remove dev artifacts, research docs, wrong lockfiles

Remove files that shouldn't ship in this PR:
- docs/research/ (aura analysis, prompt catalogs)
- docs/session-*.md, docs/SESSION-HANDOFF.md (dev notes)
- docs/superpowers/ planning and spec docs
- pnpm-lock.yaml at root and cli (repo uses bun, not pnpm)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(CLAUDE.md): align with main — slim format, add website-to-hyperframes mention

Main PR #283 removed the full skills table from CLAUDE.md and moved it
to AGENTS.md. Align with that decision: use main's slim dev-focused
format, fix pnpm→bun references, add one-line /website-to-hyperframes
pointer.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(cli): add capture command to help groups

The capture command was registered in cli.ts but missing from
the help groups, so it wouldn't appear in `hyperframes --help`.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* style: format skill reference files (oxfmt)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: regenerate bun.lock after rebase

The lockfile was stale after rebasing onto main — bun install
--frozen-lockfile failed in CI because new dependencies (google/genai,
patchright, purgecss) weren't reflected in the lockfile.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: address PR review comments + improve capture quality

Review fixes (16 comments from jrusso1020 + vanceingalls):
- screenshotCapture: remove Playwright dep, use Puppeteer for all screenshots
- screenshotCapture: dynamic screenshot count based on page height (30% overlap)
- snapshot.ts: fix duration() function-vs-property bug, cross-platform path guard
- htmlExtractor: fix code injection via parameterized evaluate
- index.ts: video preview re-measures position after scroll, .env file loading
- capture.ts: BLOCKED.md on timeout failures
- gsap.ts: 5 inline-style lint tests added (all pass)
- Remove Playwright, patchright deps; @google/genai to optionalDependencies
- Gitignore: generic patterns instead of 20 hardcoded directories
- Remove asset-sourcing.md, video-recipes.md (unused, duplicated guidance)

Capture quality improvements (tested on 10+ websites):
- Color extraction: canvas-based oklch/lab resolver, pixel sampling via
  elementFromPoint, broad sweep for accent colors, gradient/shadow extraction
- Section detection: broadened selectors for div-based layouts, height cap
  to skip page-level wrappers, parent bg walkup for dark sites
- Font downloads: cap 6 per family / 30 total (Cal.com: 306→30)
- CTA detection: text pattern matching + nav context filtering
- Heading text: innerText with whitespace normalization
- Gemini captioning: maxOutputTokens 100→300, .env auto-loading
- .env.example updated with GEMINI_API_KEY docs
- TTS ranking: Kokoro first with Python 3.10+ note

* fix: address PR review comments + improve capture quality

Review round 2 fixes (jrusso1020 + vanceingalls):
- verify/index.ts: add path traversal guard (relative + isAbsolute)
- verify/index.ts: fix sections[i] undefined typecheck error (CI green)
- index.ts: escape Lottie JSON with \u003c to prevent </script> breakout
- step-4-storyboard: fix technique count contradiction (2-3 per beat, not
  across whole video)
- step-6-build: perspective tilt uses gsap.set() instead of CSS transform
  (avoids GSAP overwrite conflict)
- step-1-capture: reorder — command first, Gemini note after (zero-config
  is the default path, API key is optional enhancement)
- step-7-validate: add tsx fallback for snapshot command
- step-3-script: vary hook patterns, don't default to number every time
- assetDownloader: exempt SVGs from 10KB minimum filter (company logos
  like Hubspot/Intel/DHL are 2-6KB; HeyGen capture: 13→75 assets)

Note: adm-zip was NOT removed (reviewer #3) — it's still in
packages/cli/package.json:30. The root package.json had patchright
and purgecss removed, not adm-zip.

Note: ANTHROPIC_API_KEY not restored in .env.example — grep confirms
zero references in the entire codebase. The @anthropic-ai/sdk dependency
was removed earlier in this branch.

* refactor(capture): split index.ts (1175 to 566 lines) into modules

Mechanical extraction, zero logic changes.

New files:
- mediaCapture.ts (345 lines): Lottie preview, video manifest/screenshots
- contentExtractor.ts (314 lines): library detection, text, Gemini, asset descriptions
- scaffolding.ts (135 lines): .env loading, project scaffold generation

Also fixes false-positive BLOCKED.md with structural Cloudflare detection.
Tested on 20 websites, pre/post output identical.

* chore(capture): remove --split flow (splitter, verify, cssPurger, purgecss)

The --split feature auto-generates compositions from captured HTML — a
different approach from the /website-to-hyperframes skill workflow where
agents build compositions from scratch using the storyboard.

No skill file, no step reference, and no test session ever used --split.
Removes 923 lines of unused code + purgecss dependency.

Backed up to ~/Desktop/capture-split-backup/ for reference.

* fix(security): add ssrf protection, lottie injection fix, oom guard

- assetDownloader: add isPrivateUrl() guard blocking private IP ranges
  (127.x, 10.x, 172.16-31.x, 192.168.x, 169.254.x), cloud metadata
  endpoints, localhost, and non-HTTP schemes
- mediaCapture: fix Lottie JSON injection by loading shell HTML first
  then passing animation data via parameterized page.evaluate()
- index.ts: check Content-Length header before response.buffer() in
  Lottie network interception to avoid OOM on multi-GB responses

* fix(capture): security fixes, timeout, sub-agent dispatch instructions

Security (from miguel-heygen review):
- assetDownloader: export isPrivateUrl() SSRF guard
- htmlExtractor: add isPrivateUrl check before CSS fetch
- mediaCapture: add isPrivateUrl check before Lottie fetch
- mediaCapture: fix previewPage leak (try/finally)
- mediaCapture: skip Lottie files > 2MB for preview (CDP limit)
- contentExtractor: skip images > 4MB for Gemini captioning
- index.ts: check Content-Length before response.buffer() (OOM guard)
- snapshot.ts: register error handler before server.listen()

Capture improvements:
- Default timeout 30s to 120s (Shopify needs ~90s for Cloudflare)
- step-6-build: sub-agent dispatch template with explicit rules:
  pass file PATHS not contents, use local fonts not Google Fonts,
  verify ../assets/ references after each beat

* fix(capture): catalog before DOM mutation, networkidle2, faster Gemini

Critical: asset cataloger now runs BEFORE extractHtml which converts img
src to data URLs. Framer sites like heykuba.com went from 2 to 78 images.

- networkidle2 instead of networkidle0 (unblocks SPAs with WebSockets)
- Lazy-load wait: scroll to bottom, wait for img.complete
- CSS background-image cataloging for Framer/Webflow
- SVG naming: checks class, id, parent, inner text (not just aria-label)
- Gemini batch 5->20, pause 12s->2s (paid tier: 2000 RPM, ~0.001/img)
- maxOutputTokens 300->500, descriptions sorted captioned-first
- Remove tsx fallback from step-1 (reviewer nit, published CLI has it)

* docs(prompting): add vocabulary tables, rules, and TTS voice guide

Merges the best content from the internal prompt guide into
prompting.mdx: easing vocabulary, caption tone table, transition
energy matrix, audio-reactive frequency mapping, marker highlight
modes, TTS voice recommendations, rendering quality presets, and
framework rules (technical requirements vs best practices).

* chore: remove greensock/gsap-skills dependency, fix Math.random nuance

The bundled skills/gsap/ already covers the GSAP surface needed for
HyperFrames compositions. Installing greensock/gsap-skills on top adds
a competing full-ecosystem skill that's mostly irrelevant (ScrollTrigger,
Draggable, SplitText, etc.) and can confuse agents about which GSAP
context to load.

Also adds seeded-PRNG nuance to the Math.random() rule in the prompt
guide (matching the skill's actual guidance).

Removed from: skills.ts, README, AGENTS.md, shared AGENTS.md/CLAUDE.md,
and prompting.mdx.

* chore: require minimal reproduction link in bug report template

Adds a required "Link to reproduction" input field asking users to push
a minimal repro to a public GitHub repo (scaffolded via
`hyperframes init repro --non-interactive --example blank`).

Also consolidates the OS/Node/FFmpeg/version fields into a single
"Environment" field using `npx hyperframes info` output — fewer fields
to fill, more consistent data.

Follows the same pattern as Next.js and Gatsby issue templates.

diagnose bugs.

Vance IngallsandClaude Opus 4.6 a262ad59f3 chore(skills): remove 1,685 lines of redundant skill content (#283) 
* chore(skills): remove 1,685 lines of redundant and irrelevant skill content

- Remove 5 GSAP references irrelevant to HyperFrames (scrolltrigger,
  plugins, react, frameworks, utils) — no scroll, no frameworks, no
  interactive plugins in video compositions
- Remove shader-setup.md and shader-transitions.md — duplicated by
  @hyperframes/shader-transitions package (packages/shader-transitions/)
- Remove marker-highlight.md and examples.md — JS library docs superseded
  by css-patterns.md (deterministic, GSAP-driven, fully seekable)
- Trim CLAUDE.md to dev-only instructions — move product docs (transcription,
  TTS, player) to skills where they belong
- Deduplicate house-style.md typography/motion sections — point to
  dedicated references instead of repeating rules
- Clean up stale references to deleted files across SKILL.md and catalog.md
- Update gsap skill description to reflect HyperFrames-only scope

Skills: 5,230 → 3,714 lines (29% reduction)
CLAUDE.md: 204 → 50 lines (75% reduction)

P0: Document HyperShader as IIFE global name in shader-transitions README
P1: Replace async fetch() with sync XHR in effects.md audio data loading
    (fetch violates synchronous timeline construction rule in SKILL.md)
P1: Change <div> to <span> in css-patterns.md marker highlight patterns
    (<div> inside <p> is invalid HTML, breaks layout in inline contexts)
P2: Clarify bgColor as fallback color in shader-transitions README
P2: Add data-start to Composition Clips table in SKILL.md
    (root composition element needs data-start="0", linter enforces it)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(templates): update init templates to match trimmed skill scope

- Remove ScrollTrigger/plugins/React/Vue/Svelte from gsap skill description
- Replace class="clip" with accurate pattern examples in skill intro text
  (class="clip" is still in Key Rules where it belongs)

* fix(skills): remove contradictory 5:1 contrast threshold from house-style

house-style.md said 5:1 minimum, but hyperframes validate enforces
WCAG AA (4.5:1 normal text, 3:1 large text). Now defers to validate
instead of stating a conflicting number.

James Russo acf8223171 fix(skills): correct README skills table and move orphaned scripts into hyperframes skill (#282) 
## What

Fixes the README skills table to match actual skill names, and moves two orphaned script directories into the `hyperframes` skill where they belong.

## Why

**README**: Listed `hyperframes-compose` and `hyperframes-captions` as separate skills — these don't exist. Captions/compose are part of the `hyperframes` skill. Also listed `gsap-core, gsap-timeline, gsap-plugins, ...` but the actual skill is just `gsap`. Missing `hyperframes-cli` entirely.

**Orphaned scripts**: `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/` had scripts but no `SKILL.md` — they looked like broken skills and wouldn't be installed by `npx skills add`. They're helper scripts invoked by the main `hyperframes` skill (SKILL.md already references them in the "Quality Checks" section). Moving them under `skills/hyperframes/scripts/` makes them part of the skill they belong to.

## How

**README skills table** — corrected to match the 4 actual skills:
- `hyperframes` (was `hyperframes-compose` + `hyperframes-captions`)
- `hyperframes-cli` (was missing)
- `hyperframes-registry` (unchanged)
- `gsap` (was `gsap-core, gsap-timeline, gsap-plugins, ...`)

**Script moves:**
- `skills/hyperframes-animation-map/scripts/animation-map.mjs` → `skills/hyperframes/scripts/`
- `skills/hyperframes-contrast/scripts/contrast-report.mjs` → `skills/hyperframes/scripts/`
- Removed empty `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/`
- Updated path references in SKILL.md, both script headers, and `contrast-audit.browser.js`

## Test plan

- [ ] `grep -r "hyperframes-animation-map\|hyperframes-contrast" --include="*.md" --include="*.mjs" --include="*.js" --include="*.ts" .` returns no results
- [ ] `ls skills/` shows only `gsap`, `hyperframes`, `hyperframes-cli`, `hyperframes-registry`
- [ ] README skills table matches `skills/*/SKILL.md` names
- [x] Documentation updated (if applicable)

James Russo 8551cffddd docs: add AGENTS.md for universal AI assistant configuration (#278) 
## What

Adds `AGENTS.md` at two levels:
1. **Repo-level** (`/AGENTS.md`) — for contributors working on HyperFrames itself
2. **Project-level** (`packages/cli/src/templates/_shared/AGENTS.md`) — scaffolded into user projects by `hyperframes init`

Also replaces the previous `AGENTS.md → CLAUDE.md` symlink with a standalone file.

## Why

AGENTS.md is the emerging universal standard for AI coding tool configuration, supported by Claude Code, Cursor, GitHub Copilot, Gemini CLI, and Codex (60K+ repos). Remotion already has one. For a project that positions itself as AI-native, this is a gap.

The project-level file (scaffolded by `init`) ensures every AI tool — not just Claude — gets framework context when working on a user's composition project. The symlink was replaced because symlinks are fragile on Windows and the content should differ (repo-level covers build/test, project-level covers composition rules).

## How

- **Repo-level AGENTS.md**: Build/test/lint commands, project structure, key conventions, skills install, doc links
- **Project-level AGENTS.md**: Composition-specific — skills, CLI commands, project structure, linting workflow, key rules, doc links
- **CLAUDE.md** remains for Claude-specific skill invocation syntax (slash commands)

## Test plan

- [ ] Verify AGENTS.md renders correctly on GitHub
- [ ] Verify no duplication with CLAUDE.md (AGENTS.md = universal basics, CLAUDE.md = Claude-specific slash commands)
- [ ] Manual testing performed
- [x] Documentation updated (if applicable)

Miguel Ángel d3f2295d80 feat(skills): add contrast audit + animation map quality skills (#267) 
## Summary

Two new quality skills + CLI integration that give agents feedback loops they currently lack — pixel-level contrast auditing and structured animation analysis.

### What this unlocks for agents

**Agents can now catch accessibility failures that humans and LLMs consistently miss.** The contrast audit runs automatically on every `hyperframes validate` and reports WCAG AA violations as warnings. In the eval, 4 out of 5 palettes had failing contrast — every baseline composition shipped broken, every treatment composition caught and fixed it.

**Agents can now reason about animation choreography.** The animation map produces a structured JSON report with:
- Per-tween natural language summaries ("card1 slides 23px up over 0.5s, fades in, ends at (120, 200)")
- ASCII timeline showing the full choreography as a Gantt chart
- Stagger detection with actual intervals ("3 elements stagger at 120ms" — validates against brief specs)
- Dead zone detection (periods >1s with no animation — missing entrance or intentional hold?)
- Element lifecycles (first/last animation, final visibility — catches elements that enter but never exit)
- Scene snapshots at 5 timestamps (what's on screen at any moment)

### Changes

**Skills (new)**
- \`skills/hyperframes-contrast/\` — WCAG contrast audit skill + script
- \`skills/hyperframes-animation-map/\` — animation analysis skill + script

**CLI**
- \`hyperframes validate\` now runs contrast audit by default (warnings, not errors)
- \`hyperframes validate --no-contrast\` to skip
- \`hyperframes render --html-only\` compiles HTML without video encoding
- Browser-side WCAG code in \`contrast-audit.browser.js\`, inlined at build time via esbuild text loader

**Producer**
- Exported \`compileForRender\` for the \`--html-only\` flag

### Eval results

5 prompts x 2 arms = 10 compositions. Arm A = baseline skills. Arm B = +contrast +animation-map.

| Prompt | Failing color | Before | After |
|--------|--------------|--------|-------|
| Halflife | Cement on Ink | 2.98:1 | 5.33:1 |
| Meridian | Ash on Midnight | 2.08:1 | 5.44:1 |
| Typesmith | Pencil on Paper | 3.19:1 | 5.50:1 |
| Lattice | Gray-600 on Terminal | 2.59:1 | 7.50:1 |

Animation map correctly enumerated 142 tweens across 5 compositions, detected stagger groups, flagged pacing issues, and produced scene snapshots.

### Dedicated evals

https://www.heygenverse.com/a/2cac956b-3d14-47bf-90e8-3c1f50e671f3

## Test plan

- [x] Eval: 10 compositions (5 baseline, 5 treatment), all rendered
- [x] Contrast audit caught 4/4 failing palettes, 0 missed
- [x] \`hyperframes validate\` shows contrast warnings by default (exit 0)
- [x] \`hyperframes validate --no-contrast\` skips audit
- [x] \`hyperframes validate --json\` includes contrast data
- [x] Animation map tested on 3 compositions (17, 27, 51 tweens)
- [x] Stagger detection, dead zones, snapshots, timeline all verified
- [x] \`bun run build\` passes
- [x] \`bun run lint\` passes (0 errors, 0 warnings, 0 skill lint issues)

James Russo 13ab1932ad feat(cli): catalog browser command (#271) 
Adds `hyperframes catalog` for browsing the registry:

- Default: non-interactive table output (agent-friendly)
- --type block/component and --tag filters
- --json for machine-readable output
- --human-friendly for interactive picker that installs on select

Registered in cli.ts, help.ts, documented in docs/packages/cli.mdx.

James Russo 4bde66f532 feat(skills): hyperframes-registry skill (#261) 
## What

New skill `hyperframes-registry` that teaches AI coding agents how to install and wire registry blocks and components into HyperFrames compositions.

### Skill structure
```
skills/hyperframes-registry/
  SKILL.md                          — triggers, overview, quick reference
  references/
    install-locations.md            — default paths, hyperframes.json config
    wiring-blocks.md                — iframe inclusion, data attributes, positioning
    wiring-components.md            — snippet merging (HTML, CSS, JS, timeline)
    discovery.md                    — manifest reading, item fields, available items table
    demo-html-pattern.md            — why components ship demo.html, structure conventions
  examples/
    add-block.md                    — worked example: data-chart block install + wiring
    add-component.md                — worked example: shimmer-sweep component install + wiring
```

## Why

Phase B of the catalog plan (PR 10). Without this skill, agents using `hyperframes add` have to guess how to wire installed items into compositions. The skill encodes the iframe/snippet patterns so agents get it right on the first attempt.

## How

- SKILL.md frontmatter triggers on: `hyperframes add`, "block", "component", `hyperframes.json`
- References cover every step: discovery, install, wiring blocks (iframe), wiring components (snippet merge), and the demo.html convention
- Two worked examples walk through complete install-to-preview workflows
- Updated CLAUDE.md skills table + trigger rules, README.md skills table, docs/packages/cli.mdx

## Test plan

- [x] `scripts/lint-skills.ts` passes (checked 4 skill files, no issues)
- [x] `oxfmt --check` passes on all markdown files
- [x] SKILL.md frontmatter has valid `name` and `description`
- [x] All reference links in SKILL.md resolve to existing files
- [x] CLAUDE.md, README.md, and docs CLI page updated with new skill

James RussoandClaude Opus 4.6 b23b0751da fix(player): parent-frame media playback for mobile (#266) 
* fix(player): parent-frame media playback for mobile

Mobile browsers block media.play() inside iframes when the user
gesture happened in the parent frame — postMessage doesn't transfer
user activation (per the User Activation v2 spec).

## Problem

The player renders compositions in a sandboxed iframe. When a user
taps play in the parent frame, the player sends a postMessage to the
iframe's runtime, which calls audio.play(). On mobile, this fails
silently because the iframe has no user activation context.

## Solution

The player now extracts ALL timed media elements (audio/video with
data-start) from the iframe's DOM (same-origin access), creates
parent-frame copies, and disables the iframe originals. On play(),
parentMedia.play() runs synchronously in the gesture call stack,
satisfying mobile autoplay policy.

### Generic media handling

- Finds all `audio[data-start], video[data-start]` in the iframe
- Creates a parent-frame copy for each (Audio or Video element)
- Preserves data-start offsets for correct seek positioning
- Strips data-start from iframe elements so the runtime ignores them
- Falls back to iframe media for cross-origin iframes

### `audio-src` attribute

Convenience for the common single-narration case. When set, the
player starts preloading audio immediately — before the iframe loads.
This eliminates the loading delay that caused jittery playback.

### No active sync

Both parent media and the GSAP timeline are real-time systems. When
started simultaneously, they naturally stay within ~10ms — no drift
correction needed. Active sync with coarse granularity (50ms polling)
caused MORE jitter than it prevented via repeated audio seeks.

## CI

- Added unified `test` job replacing separate per-package test jobs
- Added root `test` script: `bun run --filter '*' test`
- New packages with test scripts are automatically included
- Added happy-dom for player DOM tests

## Tests

- 10 new tests for parent-frame media: preloading, play, pause,
  seek, muted/rate sync, cleanup, attribute changes
- All 21 player tests pass

* fix(cli): update tests for new id field and GSAP lint rule

- normalize.test.ts: loadTranscript now assigns id fields (w0, w1, etc.)
  to SRT/VTT results and empty string for words-json passthrough
- lintProject.test.ts: add GSAP CDN script to validHtml() fixture to
  satisfy the missing_gsap_script lint rule added in core

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(cli): add missing data-start/data-duration to validHtml fixture

The validHtml() test fixture was missing data-start and data-duration
attributes, triggering the root_composition_missing_data_start and
root_composition_missing_data_duration lint warnings.

* fix(ci): fetch LFS objects for producer test job

Producer regression tests compare rendered output against reference MP4
files stored in git LFS. Without lfs: true, checkout fetches pointer
files instead of actual videos, causing "moov atom not found" errors.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* ci: remove redundant test-producer job

The regression workflow already runs the same 28 producer fixtures
in a Docker container with prod-matching Chrome/fonts/ffmpeg, sharded
across 8 parallel matrix jobs with 40-min timeouts. The CI test-producer
job was a duplicate that ran on bare runners with worse determinism
and a 15-min timeout too short for all fixtures.

James Russo 08fb1de61f feat(cli): add command + hyperframes.json (#256) 
## What

PR 5/17 of the catalog system rollout. Adds the `hyperframes add` verb for installing blocks and components from the registry into an existing project, plus the `hyperframes.json` project config that tells `add` which registry to use and where to drop files. Stacks on #255.

- **`packages/cli/src/commands/add.ts`** — new `hyperframes add <name>` command. Resolves an item, validates target paths, installs files in parallel, builds an include snippet, copies it to the clipboard. Exposes a testable `runAdd(opts)` function; the citty default wraps it with console output + exit handling
- **`packages/cli/src/utils/projectConfig.ts`** — read/write/normalize `hyperframes.json`. Tolerant to missing and partial configs
- **`packages/cli/src/utils/clipboard.ts`** — minimal cross-platform clipboard (pbcopy / clip.exe / wl-copy / xclip / xsel). Zero deps. Gracefully no-ops in headless environments
- **`packages/cli/src/commands/init.ts`** — write `hyperframes.json` during scaffold if not already present
- **`packages/cli/src/cli.ts`** + **`help.ts`** — register `add` under Getting Started (directly below `init`)

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a).

## UX

```bash
# Scaffold a project (now writes hyperframes.json too)
npx hyperframes init my-video --example blank
cd my-video

# Add a block — files land, snippet copied to clipboard
npx hyperframes add claude-code-window
#  ✓ Added claude-code-window (hyperframes:block)
#    compositions/claude-code-window.html
#
#  Include snippet:
#    <iframe src="compositions/claude-code-window.html" data-start="0" data-duration="6"></iframe>
#
#  Copied to clipboard — paste into your host composition.

# Add a component effect
npx hyperframes add shader-wipe

# Headless / CI — no clipboard, JSON output for tooling
npx hyperframes add shader-wipe --no-clipboard --json
```

Running `hyperframes add warm-grain` (an example) errors clearly pointing to `init --example`.

## Docs (bundled in this PR per the tracker principle)

- `docs/packages/cli.mdx` — new `add` subsection under Commands (flags, examples, trigger rules) + new `hyperframes.json` section describing the config file shape

## Tests

- **`packages/cli/src/commands/add.test.ts`** — 11 tests:
  - `remapTarget` / `buildSnippet` pure helpers (5 tests)
  - `runAdd` integration against a mocked `fetch` registry: block install lands files + returns snippet, component install respects `paths.components` remap, example-typed names throw `AddError` with code `example-type`, unknown names throw `AddError` with code `unknown-item` (4 tests plus 2 covering block default path and non-default path preservation)
- **`packages/cli/src/utils/projectConfig.test.ts`** — 9 tests:
  - Write/read round-trip, partial-config normalization, corrupt-file handling, absent-file fallback to defaults, custom paths preserved
- **CLI suite:** 92 passed (was 72 on #255, **+20**). Same 4 pre-existing failures unchanged

## Scope decisions

- **`init.ts` full port to new resolver deferred.** The original plan bundled a removal of the `packages/cli/src/templates/` compat shim. That's ~300 more lines and isn't required for `add` to work. The compat shim from #254 still functions; a separate cleanup PR handles it
- **No ajv runtime schema validation.** Manifests are trusted as schema-valid. Full validation lands when third-party registries arrive (PR 14/15). Path safety is still enforced by the installer's `assertSafeTarget` guard
- **Default project paths stay under `compositions/`.** Blocks → `compositions/<name>.html`; components → `compositions/components/<name>/<file>`. Users override via `hyperframes.json#paths`

## Breaking / migration

**None.** Pure additive — new command, new file types, no existing commands or flags change. `init.ts` now writes `hyperframes.json` but that's a new additional file, not a modification of existing output.

## Stacks on

#255 — base branch. When #255 merges, this rebases onto `main`.

## Next in stack

PR 6 — `feat(registry): seed block — claude-code-window`. First real registry item. Exercises the full `hyperframes add <name>` flow end-to-end against a committed item on `main`.

James Russo c8acd8abd8 feat(cli)!: rename --template to --example (#255) 
## What

PR 4/17 of the catalog system rollout. **Single clean cut** — the old flag is gone, replaced by `--example`. Alias changes from `-t` to `-e`. Stacks on #254.

- Rename `--template` → `--example` (alias `-e`) on `hyperframes init`
- Accept `--template` as a recognized-but-errored flag so users get a clear rename hint instead of citty silently ignoring the flag and producing a blank project
- Update all user-visible strings that referenced "template" as a user-facing concept in the init flow (picker prompt, step comments, offline-fallback suggestion)
- New `init.test.ts` covering both the success case (`--example` scaffolds) and the error case (`--template` exits 1 with rename hint)

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a).

## ⚠️ Breaking change

`--template` is no longer accepted. Example:

```bash
# before
npx hyperframes init my-video --template warm-grain

# after
npx hyperframes init my-video --example warm-grain
```

Users who still type the old flag will see:

```
The --template flag was renamed to --example. Example:
  npx hyperframes init my-video --example warm-grain
```

and the command exits with code 1. This is **user guidance, not backwards compat** — the old flag's behavior is fully gone.

## Docs (bundled per the tracker principle)

- `docs/templates.mdx` — every `--template` reference
- `docs/quickstart.mdx` — agent-mode and video-mode examples
- `docs/packages/cli.mdx` — prose, `--help` flag table, `-e` alias
- `packages/cli/src/docs/templates.md` — CLI-embedded help topic
- `README.md` and `CONTRIBUTING.md` — not affected (no flag references)

User-facing renames of the `templates.mdx` page title, nav entry, and URL route are deferred to PR 11 (catalog discoverability UX) as planned.

## Why

1. **"examples"** matches shadcn + Remotion convention for full-project scaffolds and frees the word "template" for future parameterization work (string templating, placeholder substitution)
2. Once `hyperframes add` lands in PR 5, "template" vs "block" vs "component" would be three subtly different concepts sharing one word — renaming the old one to "example" makes the taxonomy self-explaining

## How

- **citty silently ignores unknown flags.** Naively removing `--template` would cause `hyperframes init my-video --template warm-grain` to silently fall through and scaffold a blank project. So `--template` stays declared in the args schema, but its run handler immediately errors with a rename hint and exits 1
- **Internal names unchanged** — `templateId` local variables, `getStaticTemplateDir` function, `BUNDLED_TEMPLATES` constant. They're implementation details; their rename is scheduled for PR 5 when the compat shims in `packages/cli/src/templates/` are fully removed alongside the `init` refactor

## Test plan

- [x] `bun run test` in `packages/cli`: **72 passed** (was 70 on #254, +2 new `init.test.ts` cases). Same 4 pre-existing failures unchanged
- [x] **New unit tests** in `init.test.ts`:
  - `--example blank` non-interactive: exits 0, writes `index.html` to the target dir

## Incidental fix

Resolver test regression from PR 3's simplify follow-up: `loadAllItems`' warning-path test was still spying on `console.warn` after the `onWarn` callback refactor. Now uses the callback directly.

James Russo 969474e843 feat(cli): registry resolver + installer (#254) 
## What

PR 3/17 of the catalog system rollout. Introduces the registry resolver/installer abstraction. No UX change — `init --template` still works identically. Stacks on #253.

**New module: `packages/cli/src/registry/`**
- `remote.ts` — fetches manifests (`registry.json`, `registry-item.json`) and item files from a GitHub-hosted registry. 24h cache on manifests; item files stream straight to `destDir`
- `resolver.ts` — `listRegistryItems`, `loadAllItems` (parallel fetch for picker UX), `resolveItem` (single-item fetch with `Available:` error)
- `installer.ts` — `assertSafeTarget` (runtime path-traversal guard) + `installItem` (parallel file download with up-front validation; all-or-nothing semantics)
- `index.ts` — barrel

**Registry content:**
- `registry/registry.json` — top-level manifest in PR 1's `RegistryManifest` shape. 8 examples
- `registry/examples/<id>/registry-item.json` — per-item manifest for each existing example, generated from legacy `templates.json` + HTML data-attribute probing
- `registry/examples/templates.json` — **deleted**, replaced by the above

**Compat layer:**
- `packages/cli/src/templates/{remote,generators}.ts` — thin shims that delegate to `../registry/`, keeping `init.ts`'s existing imports stable. `init.ts` doesn't move to the new API until PR 5 where it's part of a larger UX pass

**Tooling:**
- `scripts/generate-registry-items.ts` — idempotent one-off generator for this PR, kept in-repo for future example additions (`--only <name>` flag)

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a). Tracker entry in local `hyperframes-catalog-plan.md`.

## Why

Every future PR (`hyperframes add`, seed blocks, seed components, custom registries) otherwise has to keep piling onto the ad-hoc fetch + `cpSync` pattern in the old `fetchRemoteTemplate`. The new module is the single place that understands the registry wire format and file layout. **This is also where PR 1's schema comes alive.**

## How

### Scope-trimmed from the plan

- **No transitive dependency resolution yet.** Examples have no deps today. `resolveItem` doesn't walk `registryDependencies`; PR 5 adds that when blocks/components need it.
- **No ajv schema validation yet.** TS types + runtime path-traversal guard are the only safety nets. Full JSON-Schema validation lands when the registry starts accepting third-party content (PR 14 / custom registries).
- **init.ts refactor deferred to PR 5.** Compat shims keep this PR small and reviewable. PR 5 rewrites init alongside adding the `add` command.

### Safety

- `assertSafeTarget` rejects absolute paths, `..` segments, Windows drive letters, and any target that `path.resolve` shows to escape `destDir`. Mirrors the PR 1 schema `pattern`/`not.anyOf` on `target`, but runs at install-time so a registry that bypasses schema validation still can't write outside the project
- Up-front validation in `installItem` means a malformed item fails **before** any file is written. Atomic-ish semantics: all files land or none do

### Caching

- 24h manifest cache lives at `~/.hyperframes/cache/` per existing convention, but now keyed by `<baseUrl>__<kind>__<name>.json` so PR 14 custom registries can coexist

## Test plan

- [x] `bun run test` in `packages/cli`: **70 passed** (was 57 on #253, +13). Same 4 pre-existing failures (SRT/VTT whisper normalizer + `lintProject` clean-project test) — identical to main. No regressions
- [x] **Resolver unit tests (8):** filter by type, parallel load with fail-safe, resolve-by-name with `Available:` error message, unreachable-registry handling
- [x] **Installer unit tests (5):** accepts simple relative paths, rejects `..` segments, rejects Unix absolute paths, rejects Windows drive letters, permits `.` and dotfile-like names
- [x] **Smoke test**: `hyperframes init /tmp/x --template blank` (bundled code path, unchanged) works end-to-end
- [x] `bunx oxfmt --check` + `bunx oxlint`: clean
- [x] Pre-commit typecheck (core + studio): clean. CLI typecheck has 2 pre-existing errors (`render.ts`, `studioServer.ts` — unrelated `"mov"` format issue on main)
- [ ] **Smoke test remote fetch (`--template warm-grain`)** — verifiable only post-merge; registry paths live on `main` after this PR lands

## Breaking / migration

**No end-user-visible UX change.** `init --template <name>` still works the same way. Internally, `templates.json` is gone and the CLI now reads `registry.json` + `registry-item.json` per example.

Installed CLIs on old versions (`hyperframes@0.1.0`–`0.3.0`) already broke at PR 2 merge (see #253 rollout note). The next CLI release after this lands (`0.3.1`+) is the full fix.

## Commits

1. `generate-registry-items.ts` + generated manifests + deleted `templates.json`
2. Resolver + installer + compat shims
3. Unit tests

(All squashed into one commit on this branch; see `git log feat/registry-resolver ^refactor/registry-examples-dir`.)

## Stacks on

#253 — base branch. When #253 merges, this rebases onto `main`.

## Next in stack

PR 4 — `feat(cli)!: rename --template to --example`. Single clean cut, no alias. Tiny PR (~150 lines) that mostly updates `init.ts`'s argument schema, help text, and docs. Depends on this PR so the new flag name can be applied against the refactored code path.

James Russo 69d9f08061 refactor: migrate templates/ → registry/examples/ (#253) 
## What

PR 2/17 of the catalog system rollout. **Physical directory rename.** Stacks on #252.

- `git mv templates/ registry/examples/` — all 8 example directories (`decision-tree`, `kinetic-type`, `nyt-graph`, `play-mode`, `product-promo`, `swiss-grid`, `vignelli`, `warm-grain`) plus `templates.json`
- `packages/cli/src/templates/remote.ts` — `TEMPLATES_DIR` constant from `"templates"` → `"registry/examples"`, exported for regression testing
- `scripts/generate-template-previews.ts` — `remoteTemplatesDir` resolved to the new path
- Comment updates in `packages/cli/src/templates/generators.ts` and `packages/cli/src/commands/init.ts`
- New regression test `packages/cli/src/templates/remote.test.ts` pinning the path constants so future reverts fail a test instead of silently breaking installed CLIs

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a).

## Why

The current `templates/` directory is a flat "things that scaffold projects" bucket. The catalog model splits content into three tiers: **examples** (full projects — what today's templates are), **blocks** (sub-compositions), and **components** (effect snippets). `registry/examples/` is the canonical home for what was previously at `templates/`, and this PR makes room for `registry/blocks/` and `registry/components/` in future PRs without top-level clutter.

## How

- `git mv` preserves file history — GitHub renders these as renames, not deletions + additions.
- Remote template fetch via giget reads `TEMPLATES_DIR`, so updating that one constant is sufficient for the CLI's remote code path.
- The CLI's **internal** `packages/cli/src/templates/` directory (which holds the `blank` and `_shared` bundled assets plus `generators.ts`/`remote.ts`) is a separate concept and is **not** touched here. Renaming that module belongs to PR 3 where the abstraction changes to a registry resolver.
- `templates.json` keeps its existing shape and location (now at `registry/examples/templates.json`). **PR 3 will transform it** to the new `registry.json` shape introduced in PR 1 and generate a per-item `registry-item.json` for each example. Leaving the shape change to PR 3 keeps this PR a pure physical move.

## ⚠️ Breaking change for previously-installed CLIs (`hyperframes@0.1.0` – `0.3.0`)

**What happens:** every published CLI version has `TEMPLATES_DIR = "templates"` baked in. After this PR lands on `main`, those CLIs will 404 on:

- `raw.githubusercontent.com/heygen-com/hyperframes/main/templates/templates.json` (manifest list) — caught silently in `listRemoteTemplates`, so the template picker falls back to showing only `blank`
- `github:heygen-com/hyperframes/templates/<id>#main` (giget download) — raises "Template downloaded but missing index.html"

**Decision: accept the break.** Hyperframes is pre-1.0 OSS with a small installed base; complex mitigations (dual-path fetch, redirect stubs, manifest-at-old-path with empty array) add permanent maintenance cost for a one-time rename.

**Rollout plan:**

1. Merge #252 (PR 1 — types & schemas) first
2. Merge this PR (#253)
3. Ship a patched CLI release (`hyperframes@0.3.1`) in the same work-day. Already-pinned old CLIs break on remote examples, but upgrading restores full functionality
4. Note the break in release notes + `CHANGELOG.md` under the `0.3.1` entry

Users still on an older CLI will see the failure only if they invoke `hyperframes init` with `--template <non-blank>`; `--template blank` (bundled) continues to work offline on every version.

## Test plan

- [x] `bun run test` in `packages/cli`: **57 passed** (was 55 on main, +2 regression tests for the path constants). Same 4 pre-existing failures (SRT/VTT whisper normalizer + `lintProject` clean-project test) — unchanged from main. No regressions
- [x] **Manual smoke test**: `hyperframes init /tmp/x --template blank` works (bundled code path, unchanged)
- [x] `bunx oxfmt --check` + `bunx oxlint`: clean
- [x] `bun run typecheck` (core + studio, pre-commit hook): clean
- [ ] **Manual smoke test for remote fetch (`--template warm-grain`)** — not verifiable locally before merge. Remote fetch resolves `github:heygen-com/hyperframes/registry/examples/<id>#main`, which doesn't exist until this PR lands. Will work on `main` immediately after merge.

## Breaking / migration

- Internal repo path changes only. `--template` CLI flag continues to accept the same template names.
- See "Breaking change for previously-installed CLIs" above — decision is to ship a simultaneous CLI release rather than add a compat shim.

## Commits

1. `d691bd1` — initial rename + CLI path constant update
2. `fc0c642` — review feedback: docstring fix, regression tests, clarifying comment in `init.ts`, export constants for testing

## Stacks on

## Next in stack

PR 3 — `feat(cli): registry resolver + installer`. Transforms `templates.json` to the new `registry.json` shape (from PR 1's schema), generates `registry-item.json` for every existing example, introduces `packages/cli/src/registry/{resolver,installer,remote}.ts`, renames the `packages/cli/src/templates/` CLI module, and refactors `init` to call through the new abstraction.

Miguel Ángel 58ddb11bc5 chore: release v0.3.0 (#249) 
## Summary

Coordinated minor bump across all published packages. No source changes in this PR itself; it is the version stamp for everything that landed on main since v0.2.5.

## Version bumps

| Package | from | to |
|---|---|---|
| `@hyperframes/cli` | 0.2.5 | **0.3.0** |
| `@hyperframes/core` | 0.2.5 | **0.3.0** |
| `@hyperframes/engine` | 0.2.5 | **0.3.0** |
| `@hyperframes/player` | 0.2.7 | **0.3.0** |
| `@hyperframes/producer` | 0.2.5 | **0.3.0** |
| `@hyperframes/studio` | 0.2.9 | **0.3.0** |

Between 0.2.5 and this release, `player` and `studio` received several patch versions on npm as we iterated on the bundler, entry point, and SSR issues. 0.3.0 collapses that into a single coordinated minor so the ecosystem is aligned again.

## What is in v0.3.0

### `@hyperframes/player`

**Restored package entry points to the compiled `dist/` output.** 0.2.5 shipped with `"main": "./src/hyperframes-player.ts"` but the published tarball only included `dist/` via the `"files"` field. Every consumer trying to import the package failed with `Module not found: Can't resolve '@hyperframes/player'`. Entry points now point at the built JS/`.d.ts` files inside `dist/`.

**DOM-based root timeline resolution in the ready probe.** In a bundled preview, `window.__timelines` contains the master composition alongside its sub-compositions, for example:

```js
{
  main: GSAPTimeline(14s),
  intro: GSAPTimeline(1.5s),
  'scene2-4-canvas': GSAPTimeline(12.6s),
  'scene5-logo-outro': GSAPTimeline(3.2s),
}
```

The probe used to select the adapter with `keys[keys.length - 1]`. Object key ordering meant the last-registered sub-composition would win, so the `ready` event reported a sub-composition's duration (e.g. 3.2s) instead of the master's 14s. The probe now looks up the root composition id from the outermost `[data-composition-id]` element in the iframe DOM and uses its key. Falls back to the last key when no element is present, so standalone sub-composition previews keep working.

### `@hyperframes/studio`

**`useTimelinePlayer.getAdapter()` uses the same DOM-based root id lookup** as the player. Previously play, pause, seek, and duration readout were all driven by whichever sub-composition happened to register its timeline last.

**`Player.tsx` loads `@hyperframes/player` lazily.** The component used to call `import "@hyperframes/player"` at module scope, which runs the package's `customElements.define(...)` side effect during module evaluation. `HTMLElement` does not exist in the Node runtime, so any consumer page that transitively imported the studio during server rendering threw:

```
ReferenceError: HTMLElement is not defined
  at module evaluation (@hyperframes/studio/src/player/components/Player.tsx)
```

The import now runs inside the mount effect via `import(...)` so it only evaluates in the browser. Added a cancellation flag and deferred cleanup so a fast unmount before the dynamic import resolves does not leak listeners or DOM nodes.

**Captions module imports stripped of `.js` extensions.** Files under `src/captions/` imported siblings as `./types.js` and `./parser.js`. That is legal ESM TypeScript but Turbopack and several other bundlers refuse to resolve those specifiers against `.ts` files inside `node_modules`, breaking any consumer build that transitively pulled in the captions module. Captions now uses extensionless imports, matching the rest of the studio codebase.

### `@hyperframes/core`, `@hyperframes/cli`, `@hyperframes/engine`, `@hyperframes/producer`

Version bump only, no source changes since 0.2.5. Kept on the same version so the ecosystem is easier to reason about.

## Impact for consumers

If you use `@hyperframes/studio` in a Next.js app:
- The play button in a bundled preview reports the correct composition duration and drives the master timeline.
- The session page no longer 500s in dev mode when the studio barrel is imported (the SSR fix).
- Turbopack builds that transitively load the captions module no longer fail on `Cannot resolve './types.js'`.

If you use `@hyperframes/player` directly:
- Consumer bundlers can resolve the package again (dist entry points restored).
- The `ready` event duration reports the master, not a sub-composition.

## After merge

Publish each package to npm with `pnpm publish` (workspace deps auto-resolve).

Vance IngallsandClaude Opus 4.6 4c5b8e38a1 feat(skills): add typography and motion principles, fix validate $& bug (#228) 
Add two new skill reference files that address measured LLM composition failures:

- fonts.md: Typography principles — banned fonts, guardrails for violations
  (pairing two sans-serifs, defaulting to 400/700 weight), and guidance the LLM
  genuinely doesn't apply without being told (register switching, tension as
  meaning, easing direction as emotion). Includes Google Fonts API discovery
  script with 7-category multi-strategy query.

- motion-principles.md: Motion design principles — guardrails for same-ease and
  same-speed defaults, y-axis entrance monotony, and guidance for build/breathe/
  resolve scene structure, hard cuts as intentional transitions, visual
  composition rules for video-not-web density.

Both files validated against baseline evals: 3 compositions created without
guidance confirmed the LLM reaches for banned fonts (Inter, Cormorant Garamond,
Playfair Display, Roboto Condensed), uses power2.out on 45-72% of tweens,
enters 80%+ of elements from y-axis, and pairs multiple sans-serifs.

Also:
- Fix validate.ts $& replacement bug (runtime source containing $& caused
  String.prototype.replace to re-insert the matched <script src=""> tag)
- Clean up font loading guidance across skills (compiler embeds automatically)
- Update house-style.md to reference fonts.md

* feat(cli): smart port selection with instance reuse

Replace the simple 10-port retry loop with best-in-class port handling:

- Multi-host port testing (127.0.0.1, 0.0.0.0, ::1, ::) catches ports
  occupied by SSH forwarding or other interfaces invisible to localhost
- HTTP probe (/__hyperframes_config) detects existing HyperFrames
  preview servers — reuses same-project instances instead of spawning
  duplicates, skips different-project instances
- PID detection via lsof for actionable "Port N in use by PID X" logs
- Expanded scan range from 10 to 100 ports
- Added --force-new flag to bypass instance detection
- Async PID detection (execFile, no shell) and parallel host testing

Fixes the "10 ports are all in use" error that occurs when zombie
preview servers accumulate or devbox port forwarding occupies ports.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat(cli): add --list and --kill-all flags to preview command

- `hyperframes preview --list` scans the port range and displays all
  active HyperFrames preview servers with their project name, directory,
  and PID
- `hyperframes preview --kill-all` kills all active preview servers
- Port scanning uses parallel batched probes (20 at a time) for speed

Gives users visibility into zombie preview servers and a one-command
way to clean them up.

Miguel Ángel 43e9252065 feat: add MOV (ProRes 4444) as transparent video output format (#224) 
## Summary

- Adds `--format mov` to the render CLI for ProRes 4444 transparent video output
- ProRes 4444 with alpha is the industry standard for transparent video overlays, supported by CapCut, Final Cut, Premiere, DaVinci, and After Effects
- WebM VP9 alpha technically works but is ignored by all major video editors — only browsers decode it
- Adds MOV to the studio export dropdown alongside MP4 and WebM

## Transparency format comparison

| Format | Codec | Alpha | Video editors | Browsers | File size |
| --- | --- | --- | --- | --- | --- |
| **MOV** | ProRes 4444 | Yes | CapCut, Final Cut, Premiere, DaVinci, After Effects | No (won't play in browser) | Large (~5-40 MB) |
| **WebM** | VP9 | Yes | None (shows black) | Chrome, Firefox | Small (~200 KB) |
| **MP4** | H.264 | No | All | All | Small |

> **Note:** ProRes MOV files do not play in Chromium browsers — they are an intermediate/editing format, not a delivery format. Use [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video) to verify transparency works correctly.

## Changes

- **CLI**: Add `mov` to `--format` validation, examples, and output path logic
- **Engine**: `getEncoderPreset()` returns ProRes 4444 (`yuva444p10le`) for `mov` format; handle `.mov` in `applyFaststart` and `muxVideoWithAudio`; add `pix_fmt` to streaming encoder ProRes path
- **Producer**: Treat `mov` like `webm` for alpha capture (PNG frames, screenshot mode, `forceScreenshot`)
- **Studio**: Add MOV option to export format dropdown and render queue hook
- **Core**: Add `mov` to studio API types, render route, and mime helpers
- **Tests**: Add encoder preset tests for mov format (42 total, all passing)

## Usage

```bash
hyperframes render --format mov --output overlay.mov
```

## Test plan

- [x] `pnpm build` passes
- [x] `pnpm --filter @hyperframes/engine test` — 42 tests pass (2 new for MOV)
- [x] `oxlint` and `oxfmt` clean on all 12 changed files
- [x] End-to-end local render produces ProRes 4444 (`yuva444p12le`) with working alpha
- [x] Docker render with `--format mov` — ProRes 4444 confirmed via ffprobe
- [x] Studio dropdown shows MOV option in built JS
- [x] Transparency verified with [rotato.app/tools/transparent-video](https://rotato.app/tools/transparent-video)

Vance Ingalls 85a76c0043 feat(cli): implement Docker rendering for deterministic output (#215) 
## Summary

- **The `--docker` flag was a no-op stub** — `renderDocker` called the same local `executeRenderJob` as `renderLocal`, no container was ever launched
- Now `renderDocker` generates a Dockerfile, builds a versioned `hyperframes-renderer:<version>` image with Chrome/FFmpeg/fonts/chrome-headless-shell, and runs the render inside a container
- Image is cached per CLI version — first render builds (~2 min), subsequent renders reuse it
- Forces `linux/amd64` platform since chrome-headless-shell has no ARM Linux binary
- Uses `execFileSync` (array form) throughout to prevent shell injection
- Forwards `--quiet`, `--gpu`, and render config flags into the container
- `Dockerfile.render` added as a reference for manual builds

## Test plan

- [x] `hyperframes render --docker` builds image and produces valid MP4
- [x] Second run reuses cached image (no rebuild)
- [x] `--quiet` suppresses container output while keeping stderr for errors
- [x] Typecheck, lint, format all pass
- [ ] Verify `--gpu` with `--docker` on a machine with GPU access

Miguel Ángel 25f34f7f93 fix(cli): fix preview opening wrong project in dev mode (#221) 
## Summary

One-character fix: removes leading `/` from the preview URL hash.

Dev mode opened `#/project/<name>` but the studio expects `#project/<name>`. The route regex in `App.tsx` (`/^#project\/([^/]+)/`) never matched the slash-prefixed hash, so it fell through to auto-selecting the first project from `/api/projects` — ignoring the project path you passed on the CLI.

## Root cause

```
// preview.ts dev mode (line 176) — WRONG
`${frontendUrl}#/project/${pName}`

// App.tsx route parser (line 34) — expects this format
window.location.hash.match(/^#project\/([^/]+)/)
```

Local-studio mode and embedded mode already used the correct `#project/` format.

## Test plan

- [x] Typecheck passes
- [x] `npx tsx cli preview /path/to/project` opens the correct project in the studio

Merge 9 GSAP skills (core, timeline, scrolltrigger, plugins, utils, react,
frameworks, performance, effects) and 6 HyperFrames skills (compose, captions,
tts, audio-reactive, marker-highlight, cli) into 3 consolidated skills:

- `gsap` — core API + timelines + performance in SKILL.md; scrolltrigger,
  plugins, utils, react, frameworks, effects in references/
- `hyperframes` — composition authoring rules in SKILL.md; captions, tts,
  audio-reactive, marker-highlight in references/
- `hyperframes-cli` — CLI commands (init, lint, preview, render, etc.)

Why: With 15 separate skills, agents must correctly trigger the right subset
for any task. "Create an animated video with captions" needed 6+ skills to
fire — each with ~90% trigger accuracy means ~53% chance of getting all of
them. With 3 skills, that same task needs just `hyperframes` + `gsap` (~90%
both fire). Progressive disclosure still works via references/ files loaded
on demand.

Also fixes: CLAUDE.md referenced `window.__GSAP_TIMELINE` (incorrect) —
corrected to `window.__timelines`.

* feat(cli): add --skip-skills flag to init command

Allow skipping the AI coding skills installation prompt during
`hyperframes init` with `--skip-skills`. Useful when skills are
already installed or when the user wants to scaffold without them.

* fix(skills): address code review feedback on consolidation

Restore content lost during over-compression:

- captions: fix overflow to `visible` (not hidden — clips glow effects),
  add container pattern warning, scale headroom formula, and self-lint
  placement guidance
- audio-reactive: restore sampling frequency pattern (per-frame tl.call
  loop vs single tween) and textShadow-on-container gotcha
- effects/typewriter: restore word rotation, appending words, spacing
  with static text, and multi-line cursor handoff patterns
- effects/audio-visualizer: restore spatial mapping conventions, fetch vs
  inline loading, WebGL/DOM rendering approaches, and canvas layering
- hyperframes-cli: restore --strict-all flag in render flags table

* fix(cli): update build:copy and template for consolidated skill names

- build:copy: reference skills/hyperframes, skills/hyperframes-cli,
  skills/gsap instead of the old 15 skill directory names
- _shared/CLAUDE.md template: update skill table to consolidated names

Miguel Ángel 5655dabff6 feat: allow clip animation + ship <hyperframes-player> web component (#209) 
## Summary

Two independent initiatives that improve agent DX and expand HyperFrames' reach.

### Initiative 1: Fix the Clip Animation Footgun

- `gsap_animates_clip_element` lint rule now uses smart detection — only errors when GSAP animates `visibility` or `display` on a clip element
- All other properties (opacity, transform, x, y, scale, etc.) are allowed silently
- This was the #1 agent failure in QA (10/10 agents hit it on v0.2.1)

### Initiative 2: `<hyperframes-player>` Web Component

- New `@hyperframes/player` package — zero dependencies, 3.3KB gzipped
- Iframe-based web component with Shadow DOM for perfect isolation
- Video-like API: `play()`, `pause()`, `seek()`, `currentTime`, `duration`, events
- Controls overlay with play/pause, scrubber (mouse + touch), time display, auto-hide
- Full docs page at `docs/packages/player.mdx`

## Before / After

### Clip animation lint

**Before (10/10 agents hit this):**

```
✗ gsap_animates_clip_element: GSAP animation targets a clip element.
  Selector "#title" resolves to element <div id="title" class="clip">.
  The framework manages clip visibility — animate an inner wrapper instead.
  Fix: Wrap content in a child <div> and target that with GSAP.
```

**After (only errors on actual conflicts):**

```
# This passes lint — no error:
tl.from("#title", { opacity: 0, y: -50, scale: 0.8 }, 0);

# This still errors — actual conflict with runtime:
tl.to("#title", { visibility: "hidden" }, 3);
✗ gsap_animates_clip_element: GSAP animation sets visibility on a clip element.
  Fix: Remove the visibility/display tween. Use opacity for fade effects.
```

### Embeddable player

**Before:** No way to embed a composition in a web page.
**After:**

```html
<script src="https://cdn.jsdelivr.net/npm/@hyperframes/player"></script>
<hyperframes-player src="./composition/index.html" controls></hyperframes-player>
```

```js
const player = document.querySelector('hyperframes-player');
player.play();
player.pause();
player.seek(2.5);
player.addEventListener('ready', (e) => console.log('Duration:', e.detail.duration));
```

## Test plan

- [x] 427 core tests pass (20 GSAP lint tests with smart detection)
- [x] 7 player tests pass (formatTime + element registration)
- [x] TypeScript compiles cleanly (core + player)
- [x] Lint: GSAP animating clip with safe props → 0 errors
- [x] Lint: GSAP animating clip with `visibility` → 1 error (correct)
- [x] Player builds to 3.3KB gzipped ESM
- [x] Lockfile updated for CI
- [x] Docs page added at `docs/packages/player.mdx`

Miguel Ángel baa3d813be fix: address QA report P0-P2 issues for 10/10 agent experience (#208) 
## Summary

Addresses all 8 issues from the QA report to improve agent and user experience.

### P0 — Must Fix

- **Blank template broken captions**: Removed `compositions/captions.html` and its reference from the blank template. Every agent (10/10) hit 404 errors during render.
- **Inner-wrapper example**: Added a clear structural comment in the blank template showing the correct `class="clip"` + inner wrapper pattern.
- **Sub-composition introspection**: `hyperframes compositions` now reads external HTML files referenced via `data-composition-src` and shows their real duration/element count instead of `0.0s / 0 elements`.

### P1 — Fix Soon

- **Font mapping warnings**: Now lists all mapped fonts, suggests alternatives (use a mapped font, add @font-face, install locally), and links to docs.
- **Browser 404s**: Non-font "Failed to load resource" 404s now prefixed with `[non-blocking]` instead of `[Browser:ERROR]`.
- **Render concurrency**: Default workers increased from `cores/2` (max 4) to `cores*3/4` (max 6). Added `--concurrency` alias.

### P2 — Nice to Have

- **Transform conflict fix suggestion**: `gsap_css_transform_conflict` now suggests exact GSAP property replacements (e.g., `xPercent: -50, yPercent: -50`).
- **Upgrade --yes**: Now actually runs the install instead of just printing the command.

## Before / After

### Font mapping warning

**Before:**

```
[Compiler] No deterministic font mapping for: DM Sans
```

**After:**

```
[Compiler] No deterministic font mapping for: DM Sans
  Mapped fonts: arial → inter, courier → jetbrains-mono, ...
  To fix, pick one:
    1. Use a mapped font name instead (see list above)
    2. Add a @font-face block in your HTML with a local or hosted font file
    3. Install the font locally on the render machine (Docker: add to Dockerfile)
    4. Add an alias to FONT_ALIASES in deterministicFonts.ts (for contributors)
```

### Browser 404s during render

**Before:** `[Browser:ERROR] Failed to load resource: the server responded with a status of 404`
**After:** `[non-blocking] Failed to load resource: the server responded with a status of 404`

### Transform conflict lint

**Before:** `Fix: Remove the transform from CSS and use tl.fromTo...`
**After:** `Fix: Remove transform: translate(-50%, -50%) from CSS and replace with GSAP properties: xPercent: -50, yPercent: -50`

### Compositions command

**Before:**

```
overlay   0.0s   1920×1080   0 elements
```

**After:**

```
overlay   8.0s   1920×1080   2 elements ← compositions/overlay.html
```

## Test plan

- [x] All 422 core tests pass
- [x] TypeScript compiles cleanly (all 4 packages)
- [x] Full monorepo build succeeds
- [x] `hyperframes init --template blank` ships without broken captions reference

James RussoandClaude Opus 4.6 29541aefaa feat(cli): prompt to install skills during init (#206) 
Replace the static "Tip" message at the end of `hyperframes init` with an
interactive prompt that offers to install AI coding skills. When the user
accepts, the skills command runs `npx skills add` with `--all` and
`stdio: "inherit"` so the native installer output is visible.

Miguel Ángel e2c8ed5d83 refactor(core): replace cheerio with linkedom to drop deprecated whatwg-encoding (#187) 
## Summary

- `cheerio` pulls `encoding-sniffer` → `whatwg-encoding@3.1.1` (deprecated), causing a warning on every `npm install -g hyperframes`
- `linkedom` was already bundled into the CLI via tsup `noExternal` and has zero deprecated transitive deps
- Rewrote `htmlBundler.ts` and `subComposition.ts` to use standard DOM APIs via `linkedom`
- Added a `parseHTMLContent` helper that wraps HTML fragments in a full document structure (required for `linkedom` to populate `document.body`)
- Removed `cheerio` from `cli` dependencies and tsup `external` list
- Replaced `cheerio` with `linkedom` in `core` `optionalDependencies`

## Test plan

- [x] All 411 tests pass (`bun run test` in `packages/core`)
- [x] Full monorepo build succeeds (`bun run build`)
- [x] TypeScript typecheck passes

Miguel ÁngelandClaude Opus 4.6 49e333e9de feat(cli): add skills command that installs all without selection (#192) 
* feat(cli): add skills command that installs all without selection

Wraps `npx skills add --all -g` so users don't need to manually
select skills or targets. Just run `hyperframes skills` and everything
gets installed to all supported AI tools.

* fix(cli): fix typecheck errors in skills command

Use spawn instead of execFile to avoid stdio type mismatch.
