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 | $0.00068 | $0.02308 |
| Opus 5.5 | $0.00027 | $0.00923 |
| Sonnet 5.5 | $0.00014 | $0.00462 |
| Haiku 4.5 | $0.00007 | $0.00231 |
Grade A, and why
media3-cast-integration 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 yesterday.
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.
This is a copy
100% identical to media3-cast-integration — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prerequisites
- Jetpack Media3 version must be
>= 1.9.0. Cast isn't available in lower versions.
Glossary
CastPlayer: Media3Playerthat controls playback on both local and remote Cast devices.RemoteCastPlayer: Media3Playerthat communicates with a Cast receiver, only used for remote playback.- Google Cast SDK: Legacy casting SDK in maintenance mode, superseded by Jetpack Media3.
OptionsProvider: Interface providing configuration options to initialize GMSCastContext.
Common guidelines
- Legacy Google Cast SDK is in maintenance mode.
- For new Cast setups:
- You must use Jetpack Media3 Cast.
- You mustn't use legacy Cast SDK unless explicitly requested.
Step 1: Set up dependencies
To complete this step, you MUST ensure the following:
-
In the app-level build file, declare the
media3-castdependency version 1.9.0 or higher.implementation("androidx.media3:media3-cast:1.11.1") -
Ensure required Media3 dependencies are present:
androidx.media3:media3-exoplayerandroidx.media3:media3-sessionandroidx.media3:media3-ui-compose
-
If the application uses legacy Views, add
media3-ui. -
Enforce the same versions across all Media3 dependencies.
-
Use configurations in "Add build dependencies" section of Getting started with CastPlayer as the source of truth.
-
For apps without an existing Cast integration:
- Verify legacy Cast SDK (
libs.play.services.cast.framework) is absent.
- Verify legacy Cast SDK (
-
If Migrating from Legacy Cast SDK:
- Add Media3 Cast dependencies first.
- Keep existing legacy dependencies untouched at this stage to prevent compilation errors.
Step 2: Update the manifest
To complete this step, you MUST ensure the following:
- Inside the manifest's
<application>tag, declare the Cast options provider. - Use
DefaultCastOptionsProviderby default. See the "OptionsProvider" section in Getting started with CastPlayer. - Declare a custom
OptionsProvideronly if explicitly requested. See Customize CastOptions. - Ensure
INTERNETpermission is present. Don't add any unnecessary permissions. - If Migrating from Legacy Cast SDK:
- Don't delete existing custom options provider files or manifest entries.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-cast-integration is a skill published in the GitHub repository ArisGuimera/MobiAI-Core (489 stars, last pushed yesterday), licensed MIT. It adds 68 tokens to every session and 2,308 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to media3-cast-integration, differing in 0 lines, and is treated as a copy.
