James RussoandJake Moran e96ebd74de feat(skills): add changelog-video skill for repo-native CC + Codex discovery (#2552)
Packages Jake Moran's changelog-video pipeline (v1, validated end-to-end
by Home on the Jun 23-29 range) as a repo-native skill set that Claude
Code (.claude/skills/) and Codex CLI (.agents/skills/) auto-discover the
moment the repo is opened. No install step; run the skill against a
changelog markdown for a given git range and it produces a lint-clean,
seam-gate-green 1080x1080 MP4 (~45-60s, Annie VO, mock-UI visualizations,
caption rail) end-to-end.

Six skills added byte-identical in both mirror dirs:
- changelog-video (pipeline entry point)
- motion-doctrine (carries seam-stamp.mjs + seam-gate.mjs)
- cut-the-curve, captions-overlay, seam-craft, oversized-cursor

Layout:
- .claude/skills/  - Claude Code project-local auto-discover
- .agents/skills/  - Codex CLI project-local auto-discover (verified via
                     Magi's clean-home Codex 0.144.3 repro; NOT .codex/skills/)

Fonts, animated background (12 MB), house BGM (5 MB), lexicon, and
align-captions ship inside the skill dirs. .gitattributes routes only
.claude/skills/**/*.{mp4,mp3} + .agents/skills/**/*.{mp4,mp3} through
LFS — narrowly scoped so unrelated Player, Studio, registry, and
marketplace media stay put. HeyGen CLI auth is the one credential the
skill needs; Node >= 22, ffmpeg, and headless Chrome are documented
alongside in both READMEs.

.gitignore: rewrites .claude/ and .agents/ blocks to keep agent-installed
skill hygiene while re-including the six repo-native skill dirs plus
README.md.

CI:
- Extends changes.skills filter to match .claude/skills/**,
  .agents/skills/**, scripts/lint-skills.ts, and scripts/check-skill-mirror.mjs.
- New 'Skills: project-native lint + mirror' job runs the extended
  lint-skills.ts (schema-driven; required { name, description } + optional
  { license, allowed-tools, metadata }, name pattern check, description
  length check) plus a new check-skill-mirror.mjs byte-integrity script
  (24 mirrored files must match; README.md deliberately per-CLI).
- Wired into 'bun run lint' locally.

Frontmatter validator:
- Rejects unsupported top-level keys (catches category:-style drift).
- Requires name + description.
- Validates name pattern (^[a-z][a-z0-9-]{0,63}$) and description shape
  (non-empty, <=1024 chars).
- Missing frontmatter block itself is a first-class error.

Also strips unsupported top-level 'category:' frontmatter from Jake's
motion-doctrine and cut-the-curve SKILL.mds (both mirrors), rewrites the
TTS invocation from ~/.claude/skills/media-use/... to the tracked
skills/hyperframes-media/scripts/heygen-tts.mjs, swaps npx hyperframes@latest
for the repo-local CLI in the gate step, and fixes a lint issue in Jake's
seam-gate.mjs (ternary-for-side-effect -> if/else).

Validated end-to-end by Home on Jun 23-29 (MP4 posted in C0ACCNHLG3U
thread 1784181166.041319). Independently reviewed R1/R2/R3 by Magi.

# Build Spec — square 1080 changelog master
Single-doc `index.html`: scenes are absolutely-positioned `.slide` clips on
track 1; the master timeline `tl` (MUST be named `tl` — seam-stamp emits
`tl.*`) is paused, padded to total duration, registered as
`window.__timelines["main"]`. See `examples/master-skeleton.html` for the
verbatim scaffold.
## Brand tokens (HeyGen for Developers)

/* ink #f5f6f4 · ink2 rgba(245,246,244,.72) · dim rgba(245,246,244,.66) —
NOT .45: the contrast gate fails small text under 4.5:1 over the glass.

```
Copy fonts from `<SKILL_DIR>/assets/fonts/` into the project's
`assets/fonts/` (local @font-face with format('woff2') embeds at render).
Glass card: chip-bg fill, 1px glass-line border, radius 22,
`box-shadow: 0 24px 60px rgba(0,0,0,.5)`. NO backdrop-filter. Chips: mono
18-22px, radius 12, 1px rgba(255,255,255,.14) border on rgba(255,255,255,.05).
Display type: ABC Solar Display 700. Body: TT Norms Pro. Everything
code/UI-label: TT Norms Mono. Safe margins x/y ∈ [76, 1004].
## Animated background (the house pattern)
Encode the bundled source to the film's exact duration — the render
compiler shortens a video's slot to the media length, so the encode must be
≥ total:
```bash
ffmpeg -y -stream_loop 15 -i <SKILL_DIR>/assets/bg-pattern.mp4 -t <TOTAL> \
-vf "scale=1080:1080,fps=30,eq=saturation=0.72,drawbox=c=black@0.5:t=fill" \
-an -c:v libx264 -crf 20 -pix_fmt yuv420p assets/bg-pattern-<TOTAL>s.mp4
```
Keep the darkening crush — the raw pattern is far too loud. Mount as
`<video id="bg-video" class="clip" muted>` on track 0 + a static
`rgba(8,10,9,.25)` scrim div. `<video>` needs the id (silent/black
otherwise) and must stay flat 2D (no 3D ancestors).
## Scene anatomy
- Chrome (untimed, z 6): kicker chip top-left `HYPERFRAMES WEEKLY · <RANGE>`,
progress dots top-right (one per theme; `tl.set` backgroundColor at each
cut — active #f5f6f4, done .45; never tl.call for state).
- Title (≤2s): mono kicker date, ABC Solar h1 ~104px, green rule sweep.
- Theme scene: sec-chip `0N · THEME NAME` (top 128) + ABC Solar headline
~54px (top 186) + the mock (from the visualization registry) filling
y ∈ [288, 944].
- Outro (≤3.5s): kicker FULL DIGEST, "See what shipped." ~96px, green rule,
mono URL chip, tag line. Fade all + chrome ~0.5s before end.
- Caption rail per `script-voice.md` (top: 1002).
## Seams + internal life (doctrine mechanics)
- `ledger.json`: every ordinary seam `cut-the-curve LEFT` (x, dir 1), exit
and entry selectors = the slide wrappers. Outro entry `travel: 8`.
- `seam-stamp.mjs --ledger ledger.json --write index.html` owns ALL wrapper
entries/exits — author none yourself. Title (film open) authors its own
entry only.
- Slides: CSS `opacity: 0` base; `data-start` = exactly the cut time.
- Each scene's shell (chip, headline, mock chrome, initial state) is
COMPOSED at local t=0 — the wrapper flies it in. Internal reveals start
≥0.4s after the cut and end ≥0.45s before the next cut (stamped exits
begin at cut 0.34s).
- Every internal beat lands on a VO word from `vo-words.json`. Name each
scene's sustained-motion route in the plan (sequenced UI life for mocks,
staged reveals for checklists). One green moment per scene.
- Init states via `gsap.set(...)` at build time; animation via sequential
`tl.to(...)` only (no plain-object keyframes, no repeat:-1, no tweening
left/top — set base position in CSS, tween x/y). Counters: object tween
with an `onUpdate` in the tween config (cache DOM refs; never
`tl.eventCallback`).
## Lint/check gotchas (all hit before, all pre-solved)
- Mock containers with intentional stacking: `data-layout-allow-overlap` on
the slide root; elements a playhead/line crosses:
`data-layout-allow-occlusion`.
- Dim text: `rgba(245,246,244,.66)` minimum (contrast gate).
- Audio: every `<audio>` carries an `id`. BGM: the house track ships at
`<SKILL_DIR>/assets/bgm.mp3` (159s instrumental) — copy it to the project
as `bgm.mp3` and mount on its own track:
`<audio id="bgm" src="bgm.mp3" data-start="0" data-duration="<TOTAL>" data-track-index="2" data-volume="0.14" data-media-start="0">`
(0.14 sits under the VO; use a user-supplied track only when given one).
- Preview server caches the bundle — RESTART after edits, then verify on the
raw comp page (`/api/projects/<id>/preview/comp/index.html`) via
`window.__player.seek(t)`.
