Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00030 | $0.00401 |
| Opus 5 | $0.00015 | $0.00200 |
| Sonnet 5 | $0.00006 | $0.00080 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
media3-transformer-editing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Trigger
Use for media editing/export flows: trim, transcode, clip export, composition, progress, cancellation, or media3-transformer.
Rules
- Do not mix editing/export ownership with playback ownership.
- Pin Media3 to
1.10.1through the version catalog. - Keep Transformer code in Android source sets; expose KMP-safe job state upward.
- Model export as a job with input URI, output path, progress, cancellation, failure reason, and cleanup.
- Check codec/container support before promising a transformation.
- Run long exports outside composables and survive Activity recreation.
- Store only safe, scoped output URIs; respect Android storage rules.
Example
media3-transformer = { module = "androidx.media3:media3-transformer", version.ref = "media3" }
data class ExportState(
val progress: Float,
val isRunning: Boolean,
val error: String?
)
Do Not
- Do not block the UI thread during export.
- Do not assume every input codec can be exported on every device.
- Do not leave partial output files after cancellation or failure.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

media3-transformer-editing is a skill published in the GitHub repository sunnat629/android-media-pack (13 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 401 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
