 - `/hyperframes-creative` — non-animation creative direction: `frame.md` / `design.md` handling, palettes, typography, narration, beat planning, audio-reactive visuals, composition patterns.
 - `/media-use` — the media OS: resolve any media need (BGM, SFX, image, icon, logo, voice, color grade, LUT) into a frozen local file or paste-ready block + ledger record; generate via TTS / music / image models when the catalog misses; transcribe, caption, remove backgrounds, and reuse assets across projects. One shared `scripts/audio.mjs` engine + manifest tracking; keeps search noise on disk.
+- `/hyperframes-audio` — mix the audio already placed in a composition: voiceover carve (dip a music bed only in the bands the voice occupies, static or dynamic, level match included), the effect chain (EQ, compressor, limiter, gate, saturation, delay, reverb, chorus, phaser, bitcrush), and automation envelopes on volume or any effect parameter. Sourcing the audio is `/media-use`; this is what happens to it afterwards.
 - `/hyperframes-cli` — CLI dev loop: `init`, `add`, `lint`, `check`, `snapshot`, `preview`, `render`, `publish`, `doctor`, `lambda` (AWS Lambda cloud rendering).
 - `/hyperframes-registry` — install and wire registry blocks and components into compositions via `hyperframes add`. Covers authoring a new block or component to contribute upstream.
 - `/figma` — import Figma assets, tokens, components, and storyboard sections → reconstructed motion (frames read as states, not slides) (REST/CLI) plus Motion animations (MCP) and shaders (MCP source / native export) into a composition.

 2. The scaffolded project template `packages/cli/src/templates/_shared/CLAUDE.md` + `AGENTS.md` — written into every `hyperframes init` project, so a stale entry there ships to users. The two template files must stay byte-identical.
 3. If the skill changes the routing surface for "make a video" requests, also update the routing table + intent layer in `skills/hyperframes/SKILL.md` AND that workflow's own route file, `skills/hyperframes/references/routes/<workflow>.md`. One file carries both halves: the input/output/trigger contract the router reads before the workflow is installed, and its interview entry (must-haves, conditionals, deferred asks, run-shape). The older `references/workflow-catalog.md` and `references/route-briefs.md` are now "moved" stubs pointing at `routes/` — don't edit them.

 Installs stay lean after that: `npx hyperframes init` keeps the **core set** fresh (the router, the `hyperframes-*` domain skills, and `media-use` — plus whatever is already installed; `/figma` stays on demand) and never expands a partial install; the creation workflows install **on demand** — the router runs `npx hyperframes skills update <workflow>` before entering one.
