media-use 是做什麼的？
The media OS for HyperFrames: resolve · generate · operate · remember — every media type, one skill, zero context noise.
First run: install and sign in to the heygen CLI (the free-usage path), then verify with node <SKILL_DIR>/scripts/resolve.mjs --doctor. Setup and providers: references/setup-providers.md.
Resolve — the one verb
node <SKILL_DIR>/scripts/resolve.mjs --type <type> --intent "<description>" --project <dir>
Returns one line: resolved <id> → <path> (<type>, <metadata>). All search noise stays on disk.
| Type | One-line intent |
|---|---|
bgm | background music (HeyGen catalog, 10k+ tracks) |
sfx | sound effects (bundled 19-file library + catalog) |
image | photos, backgrounds (HeyGen asset search, 75k+ vectors) |
icon | icons, symbols (transparent) |
logo | official brand marks (svgl → simple-icons → GitHub avatar → favicon; never redrawn) |
voice | TTS voiceover (HeyGen free-usage path; optional local Kokoro) |
grade | measured correction candidate; broad polish/stylization follows Media Treatments |
lut | user-provided or explicitly chosen reusable validated .cube file |
Before resolving fresh, list reusable candidates with --candidates and judge fit yourself — reuse rules, all flags, ingest (--from), and adopt are in references/resolve.md.
Treat broad visual feedback as media intent
When a user explicitly asks to fix, polish, stylize, obscure, emphasize, or
reveal photographic media, read references/media-treatments.md even if they
do not name color grading or an effect. Inspect the real <img>/<video>,
choose one primary intent, then use deterministic persistence and verification.
Use a matching recipe as an optional tested seed, or inspect
hyperframes media-treatment --capabilities --json, then request one relevant
family/effect with --capability <id> and assemble a custom treatment from
canonical controls. Never load --all for ordinary authoring. A treatment may
compose correction, a preset, finishing, compatible shader effects, supported
keyframes, and optional Registry overlays. Add only source-justified bounded
tuning and compatible parts, never effects merely to make the result look more
sophisticated. Persist the final combined payload with
hyperframes media-treatment.
Use one progressively escalating workflow. For video, inspect one labeled early/middle/late contact sheet rather than reading frames separately. Apply one candidate and inspect one after-sheet for ordinary correction or polish. Escalate to individual frames or moving draft evidence only when the result is ambiguous, temporal, stylized, LUT-based, HDR/LOG-sensitive, private, or brand-critical.
For ordinary correction or polish, persist the final treatment's
preset/adjustment JSON.
Do not generate a .cube LUT merely to encode exposure, shadows, contrast, or
warmth. Use a LUT only when the user supplies one or the selected treatment
explicitly owns one. resolve --type grade --for ... --analyze is measurement
evidence, not permission to replace the chosen treatment with a generated LUT.
Do not recreate supported vignette, grain, blur, pixelate, color, or treatment
effects with CSS/SVG overlays; that bypasses Studio controls and the canonical
preview/render shader path.
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 (inspect it with hyperframes media-treatment --selector '#hero' --analyze --json) |
| Photographic media that feels visually flat or off-topic | one specific source-appropriate preset or custom treatment, with the intended target named |
| A meaningful media entrance/reveal that feels static | one supported seek-safe treatment animation; preserve color unless the request also justifies a preset |
Rules that keep this a help, not nagware: grounded, not generic (no signal → no suggestion); opinionated + concrete (propose the specific fix with defaults chosen — the human approves all / some / none); once per project (one consolidated ask; respect "leave it"); surface, never silently mutate (color grades especially: propose and preview — a gray-world "correction" ruins an intentional sunset or neon look).
