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 | $0.00035 | $0.00432 |
| Opus 5 | $0.00017 | $0.00216 |
| Sonnet 5 | $0.00007 | $0.00086 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
media3-video-effects-lottie-muxer 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 12d 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 media3-effect, media3-effect-lottie, media3-muxer, visual processing, overlays, effect export, or muxed output.
Rules
- Start with
media3-transformer-editingwhen the task includes export. - Pin Media3 to
1.10.1through the version catalog. - Keep effects/export code in Android source sets.
- Separate preview playback from final export; they can have different performance and fidelity constraints.
- Validate input/output container, audio preservation, frame rate, color, and device codec limits.
- Keep Lottie asset loading deterministic and bundled or cached.
- Track effect pipeline failures separately from playback failures.
Example
media3-effect = { module = "androidx.media3:media3-effect", version.ref = "media3" }
media3-effect-lottie = { module = "androidx.media3:media3-effect-lottie", version.ref = "media3" }
media3-muxer = { module = "androidx.media3:media3-muxer", version.ref = "media3" }
Do Not
- Do not apply expensive export effects directly inside Compose state updates.
- Do not assume preview output exactly matches final muxed output without validation.
- Do not mix processing errors into generic player analytics.

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-video-effects-lottie-muxer is a skill published in the GitHub repository sunnat629/android-media-pack (13 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 35 tokens to every session and 432 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.
