WaterrrForever b9be0b2625 feat(skills,studio,media-use): the intent layer, review loop, and user memory — BRIEF.md, companion mode, recipes; /website-to-video folds into /product-launch-video (#2133)
* feat(studio,cli): per-frame board comments, self-refreshing storyboard, status-aware preview landing

Per-frame comment boxes on the storyboard board batch into
.hyperframes/frame-comments.json (a resubmit wins per frame; unconsumed
comments on other frames are kept). Submitted-but-unconsumed comments
stay visible — a toolbar banner plus a per-tile echo — until the agent
consumes the file; the banner also says what to do next (reply anything
in the agent chat).

The board keeps itself current: GET /projects/:id/signature exposes the
watcher-cached project signature, the storyboard payload carries the
signature it was derived from, and the view polls at 2s (hidden tabs
skipped, re-checked on visibility), refetching in place with no loading
flash. Posters bake the signature into their URL so tiles fill in as
sketches land and a poster that failed mid-write retries on the next
version; the empty state upgrades itself when STORYBOARD.md appears,
and its handoff prompt now points the agent at the review loop and uses
the parser's real status vocabulary (outline, not planned).

preview lands the browser on the storyboard view while the board is the
review surface — any frame built, or pure planning (srcs declared, none
on disk yet) — and on the timeline once the video is assembled.

* feat(skills): the review loop — plan, sketch, build as one shared process

hyperframes-core/references/review-loop.md is the single source for the
three-pass collaborative review: the plan proposed on a live board
(§ 1), wireframe sketches marked built with one layout question (§ 2 —
real words on plain blocks, run no CLI; a confirmed board is itself a
valid deliverable when the user asked for a storyboard, not a video),
the build dressing confirmed layouts (§ 3, worker or inline), and the
final look (§ 4). Autonomous runs skip every gate and keep one question
before render.

The three narrative workflows' Steps 3/4/6 collapse to references plus
their sketch stand-ins (captured-asset blocks for product-launch-video,
plain code panels for pr-to-video); the confirmed-sketch handoff stays
in each frame-worker prompt. general-video plans on a board for
multi-scene narrative pieces in collaborative mode — its sketch pass is
layout-before-animation with the user watching. The router treats
"I want a storyboard" as a process request rather than a route, and
closes exploratory intake by recommending a route plus how the run will
review.

The supporting contracts land next door: the comments channel (silent
submit, one reply picks it up, check the file before the words) in
brief-contract § 1; the sidecar schema and the built status rung in
storyboard-format; the mode question asked first and alone in the three
workflows' Step 0.

* feat(media-use): user memory — remembered preferences and frozen recipes

Two tiers of memory on media-use's existing two-tier storage split.

Preferences (lightweight): confirmed brief answers — destination, aspect,
language, mode, voice, style preset — recorded to the project's
.media/preferences.json (committed, the team inherits it) and promoted
to the personal ~/.media/preferences.json once the same value is
confirmed in two different projects (a sightings ledger accumulates the
cross-project evidence user-side, since project files can't see each
other). prefs.mjs get/record; merge reads project-over-user; a changed
value restarts its provenance.

Recipes (heavyweight): one approved run frozen as a named, versioned
bundle — frame.md, the storyboard skeleton (structure kept: durations,
transitions, srcs, Video direction; statuses reset to outline; content
blanked to per-frame fill-ins naming the beat's role), and the confirmed
brief values. Named folders, not content hashes: re-freezing bumps
version and archives <name>@v<N>; a freeze is already confirmed, so it
promotes to the user tier immediately. recipe.mjs freeze/list/use, plus
resolve --type recipe --entity <name> delegating like grade/lut.

16 new node --test cases; the media-use lib suite is 168/168.

* feat(skills): wire user memory into the brief and the review loop

brief-contract § 2 gains Remembered defaults: read the merged
preferences before Round 2 and let a remembered value become the
recommended option with a receipt naming its source project. Memory
changes the default, never the question — every ask-marked field still
gets asked, and what the request says this time beats what was picked
last time. Record only what the user actually confirmed (a defaulted
voice nobody chose is not an answer; a "go" that accepts the
recommended defaults is). The first record announces itself once;
after that the receipts carry the reminder. In autonomous mode a
remembered value becomes the decided value, receipt included.

The three narrative workflows read the remembered defaults before
Round 2, record the confirmed answers at the Step 0 gate, record the
chosen preset at the Step 2 gate (pr-to-video excepted — its preset is
fixed), and fall back to the remembered voice when the request names
none. general-video's discovery reads the same defaults.

Recipes wire in at both ends: Step 0 checks for a matching recipe
before the mode question — one question, plural-aware, and adopting
one fills the brief, skips the design step, and drafts the storyboard
from the frozen skeleton while every review gate still runs. The
review loop's final look (§ 4) offers the freeze once after approval,
and the confirmation teaches the recall phrase — the name is something
the system reminds the user of, never something they must remember.
The router recognizes a named recipe or "like last time" as a route.

* docs(skills): the sketch pass names check, not the deprecated validate

* feat(skills): intent-layer references — process, route briefs, capability menu, BRIEF.md format

* feat(media-use): brief skeleton as the recipe's fourth artifact; flow/storyboard preference keys

* feat(skills): the intent layer conducts every brief — workflows execute BRIEF.md

* feat(skills): retire the mode preference key; sync catalog surfaces for intent layer

* refactor(skills): dedupe router vs intent-layer guidance — one owner per rule

* feat(skills): the design ask — own spec, pick by eye from showcases, or defer

* docs(skills): the design ask says the honest line on capture routes

* feat(skills): product-launch-video absorbs website-to-video as the tour angle

* refactor(skills): keep product-launch-video pristine — a tour is brief intent, not a pipeline branch

* feat(skills): production loop + genre lenses; general-video goes freeform (route yours, laws hold)

* refactor(skills): /hyperframes is the front door - route tables and scope lists leave the workflows

* docs(skills): review-loop pass across skill catalog

* fix(cli): pass project dir to openStudioBrowser in background-server path

* feat(skills): add pitch-round reference - verbalized sampling concept gate

* feat(skills): wire pitch round into intent layer - completeness triage + route eligibility

* feat(skills): editorial capability recommendations, handoff disciplines, menu-probe split

* feat(skills): pitches carry their machinery; source-only-formed requests pitch the telling

* feat(skills): companion goes director - ceiling treatment plus blueprint/rule citation discipline

* fix(scripts): sandbox npx-leak guard - private npm global prefix keeps npx on the branch CLI

* chore(skills): resync manifest hash after formatter pass reflowed general-video tables

* fix(skills): recipe freeze reads workflow from BRIEF.md; style_preset records require workflow scope

Two holes found by a live companion-run freeze: the agent-supplied --workflow
contradicted the run's actual workflow (recipe.json said faceless-explainer,
brief-skeleton said general-video), and the style_preset lookup missed because
the preference had been recorded under the bare key.

- freezeRecipe resolves the workflow from BRIEF.md frontmatter; the flag is a
  fallback for briefless projects and a contradicting flag is ignored (noted).
- recordPreference refuses a bare style_preset — the scoped key is the only
  writable shape; freeze tolerates legacy bare records via read fallback.
- review-loop § 4 / media-use SKILL / brief-format wording follow the machinery.

media-use Agent Media OS, the single skill for every media need in a HyperFrames project. Resolve BGM, SFX, image, icon, brand logo, voice, color grade, or LUT into a frozen local file or paste-ready block + ledger record (one verb, `resolve`); generate via TTS / music / image models when the catalog misses; produce voiceover, transcription, captions, and background removal through one shared audio engine; operate on media (cut / reframe / transform); and reuse assets across projects. Keeps search noise on disk, hands the agent one path or block. Use for any audio, image, icon, logo, voiceover, caption, color-grading, or media-asset need.

media-use

The media OS for HyperFrames: resolve · generate · operate · remember, every media type, one skill, zero context noise.

Setup — install heygen first (free-usage path)

curl -fsSL https://static.heygen.ai/cli/install.sh | bash
heygen update             # free usage needs the OAuth-capable CLI (v0.3.0+)
heygen auth login --oauth # OAuth = free subscription credits; --api-key bills API credits

This unlocks the FREE path for bgm/sfx/image/icon catalog search, TTS (voice), and avatar videos. Sign in with --oauth — the free allowance rides on the OAuth session (an API key bills API credits instead). media-use requires heygen >= v0.3.0 uniformly (the OAuth free-usage path needs it), so --doctor nudges older CLIs to update even for API-key-only use. Before resolving anything, verify setup with:

node <SKILL_DIR>/scripts/resolve.mjs --doctor

What it owns (the gaps HyperFrames leaves)

HyperFrames owns media playback; media-use owns everything else. Each row is enforced by scripts/lib/coverage.test.mjs so the claim can't rot.

HyperFrames gap media-use owns it via
Audio-only, no image/icon resolve --type image|icon (heygen asset search)
No third-party brand logos resolve --type logo (svgl → simple-icons → GitHub org avatar → domain favicon)
No voice / audio generation resolve --type voice (HeyGen TTS free-usage path; optional local Kokoro) + the audio engine (audio/scripts/audio.mjs)
Scattered/duplicated audio engine one consolidated engine under audio/ (hyperframes-media retired)
No agent media-ops (cut/reframe/transform) references/operations.md + resolve --from to register outputs
No transcript-driven cutting scripts/transcript-cut.mjs compiles word-timestamp edits into cut lists
No auto-duck / publish loudness scripts/audio-duck.mjs + references/operations.md loudnorm/sidechain recipes
No cross-project memory global content-addressed cache + auto-promote (~/.media)
No color-grade authoring resolve --type grade emits a paste-ready data-color-grading block; resolve --type lut freezes validated .cube files
No image generation RAM-graded local mflux (FLUX) via scripts/lib/mflux-provider.mjs, codex image_gen upsell (scripts/lib/codex-provider.mjs)
No video generation HeyGen avatar video + image-to-video (animate any still into a talking clip), photo-avatar, dub/translate — heygen CLI free-usage path (references/operations.md); optional spec-gated local LTX (videogen in scripts/lib/local-models.mjs)
Weak local-model defaults HeyGen free-usage path via the heygen CLI; local open-source tools only as opt-in alternatives (scripts/lib/local-run.mjs)

When to use

Call resolve whenever a composition needs media: background music, sound effects, images, icons, brand logos, voice, a color grade, or a LUT. For voiceover / TTS, music, SFX, and caption timing, use the audio engine (below); background removal is delegated to the hyperframes CLI; transcription defaults to Parakeet (better than whisper.cpp: 6.05% vs 7.44% WER, 5-10x faster) via scripts/transcribe.mjs, with whisper.cpp auto-fallback (see references/operations.md). For cutting / reframing / transforming existing media, see references/operations.md. media-use searches the HeyGen catalog first for media files, resolves official logos through the logo cascade, uses local deterministic color grading for grade/lut, freezes the best match locally when a file is needed, registers it in a manifest, and hands the agent one line; all search noise stays on disk.

Be proactive — run a media opportunity pass

The human usually can't tell which media would lift the piece. You can. When you build or review a composition, do one grounded scan and then ask once — don't silently add, and don't nag per asset.

Surface an opportunity only when a concrete signal is present:

Signal detected Offer
On-screen text / a script with no voiceover TTS voiceover (audio engine)
Emoji or a <div> styled as an icon resolve real icons
Image that is a placeholder, tiny, or upscaled-looking a better image (and/or upscale — see references/operations.md)
Hard scene cuts / transitions with no sound transition sfx
A piece over ~10s with no music bed bgm
Footage that reads under/over-exposed or color-cast a corrective grade (analyze with grade --for, preview with hyperframes grade-compare)

Rules that keep this a help, not nagware:

  • Grounded, not generic. No signal → no suggestion. Never open with "want better images?".
  • Opinionated + concrete. Propose the specific fix ("add a VO from your script, swap 3 emoji for real icons, replace the 400×400 hero, whooshes on the 4 cuts"), with defaults chosen — the human just approves all / some / none.
  • Once per project. One consolidated ask, top few highest-value items. Respect "leave it" and don't re-raise.
  • Surface, never silently mutate. Color grades especially: propose and preview, never auto-apply — a gray-world "correction" ruins an intentional sunset or neon look.

Reuse before you resolve

Before resolving bgm/sfx/image/icon/logo/grade/lut, check what already exists and reuse it when it fits. media-use does not semantically match for you — you are the judge. It surfaces candidates; you decide.

node <SKILL_DIR>/scripts/resolve.mjs --type bgm --intent "upbeat tech launch" --candidates --project .
#   [project] upbeat tech launch (25s, heygen.audio.sounds)
#           .media/audio/bgm/bgm_001.wav
#   [global]  energetic tech intro (22s, heygen.audio.sounds)
#           --reuse 06e052c075fd2b80

Read the list and judge semantic fit yourself — "upbeat tech launch" ≈ "energetic tech intro" is a call only you can make from the descriptions. Then:

  • A project candidate fits → just reference its path in your composition. Nothing else to run.
  • A global candidate fitsresolve --type bgm --reuse <sha> copies it into this project (self-contained render) and records it.
  • Nothing fits → resolve fresh (--type ... --intent ...).

Trust guardrail — when unsure, resolve fresh. A redundant download is cheap; shipping the wrong asset is not. Judge fit from description + prompt + type + duration/dims. For brand/entity assets, reuse a global candidate only when the entity matches exactly — the global cache aggregates every project you have worked on, so a --candidates list can surface another client's brand mark and its prompt text. Never reuse a cross-project brand asset on a loose match.

The deterministic floor still runs automatically: an identical (case/whitespace-insensitive) repeat auto-reuses with no --candidates step. --candidates is only for the semantic layer above that floor — and a fuzzy match is never auto-applied; reuse is always your explicit call. On a resolve that misses the floor and is about to fetch, media-use prints a one-line stderr hint when similar cached assets exist, pointing you back here.

Color grading

Use grade when you need the actual HyperFrames data-color-grading value to paste onto an <img> or <video>. Core presets and params-backed library looks resolve locally; future CDN-backed library looks require network unless already frozen:

Never cat/read a .cube file into context. A 3D LUT is ~size^3 lines of raw numbers (33^3 ≈ 36k lines at the default size). It bloats context and carries zero human/agent-legible signal. To understand or choose a LUT, use hyperframes grade-compare to see it rendered, or cube-validate.mjs for a one-line {ok,size} check. Read .media/index.md or luts/index.json for the description. Never read the LUT body itself.

node <SKILL_DIR>/scripts/resolve.mjs --type grade --intent "warm daylight" --project . --json

Preset-first output uses the core runtime vocabulary and does not freeze a file:

{
  "preset": "warm-daylight",
  "intensity": 1
}

Paste it as an attribute value after JSON string escaping:

<video
  class="clip"
  src="./media/scene.mp4"
  data-color-grading='{"preset":"warm-daylight","intensity":1}'
></video>

Looks beyond the preset vocabulary freeze a validated .cube under .media/luts/ and return a block that references it:

node <SKILL_DIR>/scripts/resolve.mjs --type grade --intent "teal orange blockbuster" --project . --json
{
  "intensity": 1,
  "lut": { "src": ".media/luts/grade_001.cube", "intensity": 0.85 }
}

Use lut when you only need the reusable .cube file:

node <SKILL_DIR>/scripts/resolve.mjs --type lut --intent "teal orange blockbuster" --project .

For a describable technical look, author an explicit parametric LUT with --params:

node <SKILL_DIR>/scripts/resolve.mjs --type lut --params '{"contrast":0.2,"temperature":-0.3}' --project .
node <SKILL_DIR>/scripts/resolve.mjs --type grade --params '{"exposure":0.2}' --project . --json

For a LUT generated by your own script, ingest it with --from; media-use validates it before registration and rejects invalid or oversized cubes:

node <SKILL_DIR>/scripts/resolve.mjs --type lut --from custom.cube --project .

Parametric math (buildCube) cannot reproduce real film stocks or emulsion looks. Use a CDN-backed scanned .cube entry or ingest a real scanned .cube for those.

For visual selection, list reusable looks with resolve --type grade --candidates, write the promising entries to a grades.json, run hyperframes grade-compare --for <frame> --grades grades.json, then commit the winner with resolve -t grade as the final data-color-grading block.

Smart grade is grade --for <media>. It runs local ffmpeg/ffprobe signalstats, merges a bounded adjust suggestion into the returned block, and prints the measured evidence to stderr. Stdout remains valid JSON under --json; the suggestion is a starting point for the agent to tune, not an automatic neutralization of intentional color.

node <SKILL_DIR>/scripts/resolve.mjs --type grade --intent "warm cinematic" --for ./frame.png --project . --json

Library looks live in luts/index.json. Each entry keeps id, description, tags, and intensity, then supplies either compact params for on-demand buildCube(params) generation or a direct CDN url for future scanned .cube files. Do not commit generated .cube bodies; resolve validates generated or downloaded cubes as it freezes them under .media/luts/.

node skills/media-use/scripts/resolve.mjs --type lut --intent "teal orange blockbuster" --project . --json
node skills/media-use/scripts/lib/cube-validate.mjs .media/luts/lut_001.cube

Providers

media-use holds no keys; every external tool owns its auth. Generation is centered on the HeyGen CLI free-usage path. Install and authenticate heygen before resolving bgm/sfx/image/icon/voice/avatar-video. Local tools are opt-in alternatives where they exist: mflux for image, Kokoro for voice, Parakeet for transcription, and LTX for local video generation. resolve spec-checks AVAILABLE RAM for those local ladders (describeModelLadder); the agent can see the ladder and override.

Type Provider / path
bgm/sfx heygen catalog free-usage path
image heygen search free-usage path; optional local mflux; codex image_gen upsell
voice heygen tts free-usage path; optional local Kokoro (free, on-device)
icon heygen asset search free-usage path
logo svgl, then simple-icons, then GitHub org avatar, then domain favicon (all free)
grade/lut local core-preset map, params/CDN look index, deterministic buildCube fallback
video heygen avatar / image-to-video / photo-avatar / dub free-usage path; optional local LTX (videogen ladder)

Local Kokoro (voice), mflux (image), and LTX (video) run on-device (free, private, offline once cached). The codex CLI remains the ChatGPT-sub image upsell. Cost rule (X4): the agent confirms before an agent-initiated paid call; a user-requested one just runs.

To force a specific generator (e.g. a user says "make this image with codex"), pass --provider codex: it pins resolution to that provider and skips the free-usage default. See references/operations.md for the RAM ladders and provider recipes.

--local-only skips every network provider, including the free HeyGen ones, leaving the project + global cache and any installed local provider. For HeyGen-only types, that means no fresh resolve.

How it works

resolve runs an automatic floor, then falls through to fetching:

  1. Check project .media/manifest.jsonl for a prompt match (case- and whitespace-insensitive) — auto-reuse
  2. Scan existing assets/ directory for unregistered files that share a word with the need
  3. Check global cache ~/.media/ for a reusable asset matched on the same normalized prompt — auto-reuse
  4. Search via provider (HeyGen audio catalog, HeyGen asset search), or resolve color locally
  5. Freeze file to .media/<type>/, register in manifest, regenerate index.md, auto-promote to ~/.media/

Steps 1 and 3 are the deterministic floor: they only auto-reuse an exact-normalized match, never a fuzzy one. Semantic reuse ("close enough") is the agent's explicit call via Reuse before you resolve — it never happens automatically. The agent gets back one line; candidates, scores, provenance stay on disk.

Adopt existing projects

Most HyperFrames projects already have assets in assets/. media-use adopts them:

node <SKILL_DIR>/scripts/resolve.mjs --adopt --project .
# → adopted 9 assets from assets/
#   bgm_001 → assets/bgm/mango-fizz.mp3 (bgm, 146.6s)
#   image_001 → assets/images/avatar.jpg (image, 400×400)

ffprobe extracts real duration and dimensions. During resolve, unregistered files in assets/ matching the intent are adopted on the fly.

Reading the inventory

After resolve or adopt, read .media/index.md for the full inventory:

# .media · 4 assets

id         type   dur   dims       path                          description
bgm_001    bgm    25s   -          .media/audio/bgm/bgm_001.mp3  upbeat tech launch
sfx_001    sfx    0.6s  -          .media/audio/sfx/sfx_001.mp3  whoosh
image_001  image  -     1920×1080  .media/images/image_001.jpg   gradient tech background
icon_001   icon   -     200×200    .media/images/icon_001.png    rocket

Cross-project reuse

Assets are cached automatically on resolve. Every resolved/ingested asset is auto-promoted to the global cache at ~/.media/, so subsequent resolves for the same (or near-identical) prompt, in any project, hit the cache with no re-download and no provider call.

For a semantically similar (not identical) need in another project, the exact-match floor won't fire — use Reuse before you resolve: --candidates lists the global assets, and --reuse <sha> imports the one you pick. This is how a track resolved in one project gets reused in the next when the wording differs.

Preferences — remembered defaults

The lightweight tier of user memory: confirmed brief answers (destination, aspect, language, flow, storyboard, voice, style preset) persisted on the same two-tier split as assets — project .media/preferences.json (committed, the team inherits it) and personal ~/.media/preferences.json. A value earns the personal tier by being confirmed in two different projects, so a one-off choice never pollutes the global defaults.

node <SKILL_DIR>/scripts/prefs.mjs get --hyperframes . --json      # merged view (project overrides user)
node <SKILL_DIR>/scripts/prefs.mjs record --hyperframes . --key destination --value x-feed
node <SKILL_DIR>/scripts/prefs.mjs record --hyperframes . --key style_preset --value pin-and-paper --workflow faceless-explainer

Only what the user actually confirmed gets recorded — never an inferred or defaulted value. How workflows consume these (a remembered value becomes the recommended default with a receipt, and never skips a question) is the brief contract's rule: hyperframes-core/references/brief-contract.md § 2, Remembered defaults.

Recipes — frozen video bundles

The heavyweight tier of user memory: one approved run frozen as a named, versioned bundle — frame.md, the storyboard skeleton (structure kept, content blanked to per-frame fill-ins), the brief skeleton (from BRIEF.md when the project has one — reusable frontmatter kept, run-shape and prose blanked), and the confirmed brief values. Same two tiers: project .media/recipes/<name>/ (committed) and ~/.media/recipes/<name>/ (a freeze is already a confirmed bundle, so it promotes immediately — no two-project rule). Re-freezing a name bumps version and archives the old folder as <name>@v<N>.

node <SKILL_DIR>/scripts/recipe.mjs freeze --hyperframes . --name weekly-promo   # workflow read from BRIEF.md (--workflow only for briefless projects)
node <SKILL_DIR>/scripts/recipe.mjs list --hyperframes . --workflow product-launch-video
node <SKILL_DIR>/scripts/recipe.mjs use --hyperframes . --name weekly-promo   # also: resolve.mjs --type recipe --entity weekly-promo

The freeze is offered once after the final approval (hyperframes-core/references/review-loop.md § 4), and the intent layer (/hyperframes § 4) checks for a match before its first question. Adopting a recipe fills the brief, the design spec, and the storyboard skeleton — and unlike preferences it may skip the questions it answers: the bundle was approved as a whole, and adoption itself is the question.

Usage stats

Use resolve --stats for a local, shareable report over the current project's .media/ manifest, the global ~/.media/ cache, and local resolve misses. Human output is compact; add --json for a single machine-readable object, and --days N to window timestamped records.

node <SKILL_DIR>/scripts/resolve.mjs --stats --project . --days 7
# media-use stats
# total resolves: 12
# misses: 2
# hit rate: 86%

Files

  • .media/manifest.jsonl: machine SSOT, one JSON record per line
  • .media/index.md: agent-readable table (id, type, dur, dims, path, description)
  • .media/preferences.json: the project's remembered defaults (committed)
  • ~/.media/: global cross-project reuse cache (content-addressed, SHA-256)
  • ~/.media/preferences.json: personal remembered defaults (promoted after two projects)
  • .media/recipes/<name>/: frozen video bundles — recipe.json + frame.md + storyboard skeleton (committed)
  • ~/.media/recipes/<name>/: personal recipe tier (promoted on freeze)
  • ~/.media/misses.jsonl: local-only resolve misses, including intent text for --stats

Audio engine: voiceover, music, SFX, captions, transcription

For a full audio pass (TTS voiceover + background music + sound effects in one shot), use the shared engine at audio/scripts/audio.mjs. It takes a neutral audio_request.json and writes audio_meta.json plus assets under .media/audio/{voice,bgm,sfx}:

node <SKILL_DIR>/audio/scripts/audio.mjs --request ./audio_request.json --out ./audio_meta.json
  • Request { provider?, lang?, speed?, lines: [{ id, text, sfx?: [names] }], bgm: { mode?, query?, prompt? } }: id joins each line back to your model; bgm.mode = retrieve | generate | none (omit for auto). --only tts,bgm,sfx runs a subset and merges into an existing --out.
  • Output audio_meta.json (id-keyed): voices[].{path,duration_s,words[]} (word timestamps for captions), sfx[], bgm, total_duration_s.
  • HeyGen free-usage path: HeyGen CLI auth unlocks TTS plus music/SFX retrieval. Local/provider-specific generators are explicit alternatives where installed; run node <SKILL_DIR>/scripts/resolve.mjs --doctor before assuming retrieval or TTS will work.
  • If BGM took the generate path (bgm_pending: true), run audio/scripts/wait-bgm.mjs before final render.

Single-shot helpers: audio/scripts/heygen-tts.mjs (one voice file). Transcription / background removal / captions use the hyperframes CLI (transcribe, remove-background), see the per-topic guides in audio/references/ (tts.md, bgm.md, sfx.md, transcribe.md, remove-background.md, captions/).

Operating on media (cut, reframe, transform)

media-use resolves + remembers; for operating on assets see references/operations.md: local-tool recipes (ffmpeg trim/reframe/montage, auto-editor, scenedetect) and the local-vs-HeyGen transform table (background removal, upscale, lipsync, translate). Run the tool, then register the output with resolve --from <output> --type <type> so it joins the ledger + global cache.

CLI tools used (what to run, and how to enable each)

resolve auto-cascades; each provider shells one CLI. HeyGen is the free-usage path for bgm/sfx/image/icon catalog search, TTS (voice), and avatar video, so those capabilities need heygen installed and authenticated. Local tools are OPT-IN alternatives where they exist; install one to unlock its free, private, on-device path instead of or ahead of HeyGen for that type. Only ffmpeg/ffprobe are strictly required for the tool to run at all.

Tool Serves Install
ffmpeg/ffprobe adopt probing, smart-grade signalstats, cut, duck bake, loudnorm system package (brew install ffmpeg)
heygen catalog (bgm/sfx/image/icon) + TTS (voice) + avatar video — the free-usage path curl -fsSL https://static.heygen.ai/cli/install.sh | bash then heygen auth login --oauth (needs >= v0.3.0)
mflux-generate local image gen (FLUX), best-for-RAM uv venv ~/.venvs/mflux && VIRTUAL_ENV=~/.venvs/mflux uv pip install mflux==0.9.6
codex image gen upsell (ChatGPT sub) Codex CLI, logged in via ChatGPT (owns its own auth)
parakeet-mlx local transcription (default ASR, best) uv venv ~/.venvs/parakeet && VIRTUAL_ENV=~/.venvs/parakeet uv pip install parakeet-mlx
ltx-2-mlx local video gen git clone https://github.com/dgrauet/ltx-2-mlx && cd ltx-2-mlx && uv sync --all-extras
npx hyperframes Kokoro TTS (voice), whisper.cpp (transcribe fallback), remove-background bundled with the hyperframes CLI

The RAM-graded local-model shortlist + exact per-tier install/invoke lives in scripts/lib/local-models.mjs (the agent can read describeModelLadder(cap, specs) to see which model fits this machine). Without a tool on PATH, its provider prints a one-line diagnostic to stderr and resolve falls through where another provider exists (e.g. no mflux -> codex image upsell; no parakeet-mlx -> whisper.cpp).

heygen asset search is a pre-launch command hidden from heygen --help, but it runs; providers tag requests with the allowlisted X-HeyGen-Client-Source header (v0.3.0+).

Telemetry

resolve and the edit tools (transcribe / transcript-cut / audio-duck) send an anonymous usage event to PostHog (scripts/lib/telemetry.mjs), so we can see which capabilities are actually used. It records only the media TYPE, the resolution SOURCE, and the winning PROVIDER: never the intent text, file names, or paths, and $ip:null so no IP is stored. Best-effort and non-blocking (a resolve never waits on or fails from telemetry).

Opt out with DO_NOT_TRACK=1 or HYPERFRAMES_NO_TELEMETRY=1 (also off in CI and dev). Same public PostHog project key and opt-outs as the hyperframes CLI.

Privacy

media-use uses the same shared install id as the hyperframes CLI/studio (~/.hyperframes/config.json). When you are signed in to HeyGen, usage is linked to your account email, or username when email is unavailable, matching the CLI behavior. The events stay coarse: media type, source, provider, and small counts only; intent text and paths stay local. Disable telemetry with HYPERFRAMES_NO_TELEMETRY=1 or DO_NOT_TRACK=1.
