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 | $0.00057 | $0.00761 |
| Opus 5 | $0.00028 | $0.00380 |
| Sonnet 5 | $0.00011 | $0.00152 |
| Haiku 4.5 | $0.00006 | $0.00076 |
Grade A, and why
flutter-platform-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 2d 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.

Flutter Platform Integration
When to use
Use this for Flutter work that crosses the Dart/native boundary: platform channels, plugins, permissions, flavors, app config, deep links, push notifications, background tasks, secure storage, lifecycle hooks, or iOS/Android-specific behavior. Load it alongside flutter-implementation.
Inputs and outputs
- Inputs: SRS/architecture permission and platform requirements, API contracts, env configuration, existing Flutter plugin/channel setup, iOS/Android project files, current flavor/build configuration.
- Outputs: platform changes that are approved by architecture, configured per environment, covered by smoke/build checks, and documented in task notes or deploy reports when QA/DevOps needs them.
Procedure
- Classify the integration:
- package/plugin only;
- MethodChannel/EventChannel/FFI/custom native code;
- flavor/build-config change;
- permission/deep-link/push/background lifecycle change.
- Check authorization before changing platform capabilities:
- new plugins, permissions, background modes, associated domains, push services, and native APIs require architecture/dependency approval;
- if the requirement is absent, halt with an OQ instead of silently adding capability.
- Implement environment-safe config:
- use SRS §3.4.6 keys and the existing config loader;
- pass non-secret values through the established
--dart-define, flavor file, or build-time config path; - keep dev/staging/prod endpoints out of Dart and native source literals.
- Keep permission UX complete:
- update iOS usage descriptions and Android permission declarations;
- provide user-facing rationale/copy where required by the feature;
- handle denied, restricted, unavailable, and recoverable states in UI.
- Isolate platform differences:
- wrap platform calls behind services/repositories;
- keep widgets independent of channel names and native file paths;
- use typed DTOs for channel payloads and document nullable/error cases.
- Verify platform behavior:
- run at least one affected platform build/check when native files, plugins, flavors, or permissions change;
- test deep links, push/open flows, storage migration, channel error handling, or lifecycle paths on the relevant simulator/emulator/device;
- record any platform that could not be checked.
What ships with it
1 file 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.

flutter-platform-integration is a skill published in the GitHub repository evolplus/talos (8 stars, last pushed 28d ago), licensed Apache-2.0. It adds 57 tokens to every session and 761 once invoked, about $0.0003 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 2026-08-31.

git-safety
Git safety rules. INVOKE WHEN: git push, force push, git reset, git clean, destructive git, push force, reset hard. NEVER force push or do destructive git operations.
dogfood
Systematically explore and test a mobile app on iOS/Android with agent-device to find bugs, UX issues, and other problems. Use when asked to dogfood, QA, exploratory test, find issues, bug hunt, or test this app on mobile.
release
Cut a sim-use release end-to-end. Use when the user runs /release or asks to "ship a release", "publish a version", "cut a release", or "release to homebrew". Drives scripts/local-release.sh; never reimplement its build/sign/tarball logic.
