Agent Skills: media-use

Agent Media OS — resolve any media need (BGM, SFX, image, icon) into a frozen local file + ledger record. One verb (`resolve`) handles the full cascade — project cache, global cache, HeyGen catalog search, freeze, register. Keeps search noise on disk, hands the agent a path. Use when a composition needs background music, sound effects, images, or icons.

Description
Agent Media OS — resolve any media need (BGM, SFX, image, icon) into a frozen local file + ledger record. One verb (`resolve`) handles the full cascade — project cache, global cache, HeyGen catalog search, freeze, register. Keeps search noise on disk, hands the agent a path. Use when a composition needs background music, sound effects, images, or icons.

media-use

Resolve media needs into frozen local files. One verb, four types, zero context noise.

When to use

Call resolve whenever a composition needs media — background music, sound effects, images, or icons. media-use searches the HeyGen catalog, downloads the best match, freezes it locally, and registers it in a manifest. The agent gets back one line; all search noise stays on disk.

Resolve

node <SKILL_DIR>/scripts/resolve.mjs --type <type> --intent "<description>" --project <dir>

Returns one line: resolved <id> → <path> (<type>, <metadata>)

Types

| Type | What it finds | Provider | | ------- | ------------------- | ---------------------------------------- | | bgm | Background music | HeyGen audio catalog (10k+ tracks) | | sfx | Sound effects | Bundled 19-file library + HeyGen catalog | | image | Photos, backgrounds | HeyGen asset search (75k+ vectors) | | icon | Icons, logos | HeyGen asset search (type=icon) |

Examples

# Background music
node <SKILL_DIR>/scripts/resolve.mjs --type bgm --intent "upbeat tech launch" --project .
# → resolved bgm_001 → .media/audio/bgm/bgm_001.mp3 (bgm, 25s)

# Sound effect
node <SKILL_DIR>/scripts/resolve.mjs --type sfx --intent "whoosh" --project .
# → resolved sfx_001 → .media/audio/sfx/sfx_001.mp3 (sfx, 0.57s)

# Image
node <SKILL_DIR>/scripts/resolve.mjs --type image --intent "gradient tech background" --project .
# → resolved image_001 → .media/images/image_001.jpg (image)

# Icon
node <SKILL_DIR>/scripts/resolve.mjs --type icon --intent "rocket" --project .
# → resolved icon_001 → .media/images/icon_001.png (icon, transparent)

Flags

| Flag | Description | | --------------- | ------------------------------------------ | | --type, -t | Media type: bgm, sfx, image, icon | | --intent, -i | What you need (natural language) | | --entity, -e | Entity name for cache matching (optional) | | --project, -p | Project directory (default: .) | | --adopt | Bulk-import existing assets/ into manifest | | --json | Output JSON instead of one-line result |

How it works

  1. Check project .media/manifest.jsonl for exact-prompt match
  2. Scan existing assets/ directory for unregistered files matching the need
  3. Check global cache ~/.media/ for reusable asset
  4. Search via provider (HeyGen audio catalog, HeyGen asset search)
  5. Freeze file to .media/<type>/, register in manifest, regenerate index.md

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. Subsequent resolves for the same prompt hit the global cache at ~/.media/ — no re-download, no provider call. Promote an asset explicitly with organize --promote <id> to make it reusable across all projects.

Files

  • .media/manifest.jsonl — machine SSOT, one JSON record per line
  • .media/index.md — agent-readable table (id, type, dur, dims, path, description)
  • ~/.media/ — global cross-project reuse cache (content-addressed, SHA-256)

CLI tools used

| Tool | Purpose | Required? | | --------- | ------------------------------------------ | ------------- | | ffprobe | Probe duration, dimensions, codec on adopt | Yes | | heygen | Audio catalog, asset search | For providers |

Install the heygen CLI (single static binary, no runtime) and authenticate:

curl -fsSL https://static.heygen.ai/cli/install.sh | bash   # installs latest to ~/.local/bin
heygen update                                               # if already installed: needs >= v0.1.6
export HEYGEN_API_KEY=<your-key>                            # or: heygen auth login --key <key>

Requires heygen >= v0.1.6 — the providers tag requests with the allowlisted --headers 'X-HeyGen-Client-Source: media-use' flag, added in v0.1.6. asset search is a pre-launch command hidden from heygen --help, but it runs. Without a heygen on PATH (or a valid key) the providers print a one-line diagnostic to stderr and resolve falls through to "no provider could resolve".
