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 | $0.00032 | $0.00475 |
| Opus 5 | $0.00016 | $0.00237 |
| Sonnet 5 | $0.00006 | $0.00095 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
media3-xr-media-surface 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 Android XR media playback planning, immersive playback surfaces, spatial/large display behavior, or controller/gesture input questions.
Rules
- Verify current Android XR docs and available APIs before implementation; XR guidance can move faster than Media3.
- Start with
media3-adaptive-compose-uifor size classes, then add XR-specific interaction. - Pin Media3 to
1.10.1through the version catalog. - Keep Media3 player/session code in Android source sets.
- Decide embedded vs immersive playback before coding controls.
- For spatial video, render through Jetpack XR SDK SceneCore
SpatialExternalSurface(or its 180/360 degree variants) with a Media3ExoPlayerattached to the provided surface. - MV-HEVC spatial video playback requires Media3 1.6.0 or newer; the pinned
1.10.1satisfies this. - Make controls usable with controller, hand, gaze, or system input supported by the target XR stack.
- Provide a phone/tablet fallback path if XR APIs are unavailable.
Example
media3-exoplayer = { module = "androidx.media3:media3-exoplayer", version.ref = "media3" }
media3-ui-compose = { module = "androidx.media3:media3-ui-compose", version.ref = "media3" }
Do Not
- Do not pretend XR is just a larger phone layout.
- Do not hard-code immersive behavior without a fallback.
- Do not ship stale XR API names without checking current official docs.

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-xr-media-surface is a skill published in the GitHub repository sunnat629/android-media-pack (13 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 475 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.
