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 | $0.00101 | $0.05529 |
| Opus 5 | $0.00051 | $0.02764 |
| Sonnet 5 | $0.00020 | $0.01106 |
| Haiku 4.5 | $0.00010 | $0.00553 |
Grade A, and why
jetpack-compose-audit 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 3d 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.

Jetpack Compose Audit
This skill audits Android Jetpack Compose repositories with a strict, evidence-based report.
Skill version: 4.3.2 — released 2026-07-07. Compose track: Kotlin 2.0.20+ / Compose Compiler 1.5.4+ (Strong Skipping Mode default). See the README changelog for what changed.
It is intentionally focused on four categories:
- Performance
- State management
- Side effects
- Composable API quality
This skill does not score design or Material 3 compliance in v1. If the audit surfaces likely design-system problems, recommend a follow-up audit with the material-3 skill (reference implementation: https://github.com/hamen/material-3-skill).
Testing, focus/keyboard navigation, and Compose Multiplatform are coverage notes, not score categories. Map those surfaces when present, flag obvious risk, and recommend the focused compose-agent references (testing, focus, kmp) as follow-up work. Do not fold them into the 0-100 score unless the same root cause clearly affects one of the four scored categories.
Android launch UX resources are also adjacent coverage, not a score category. Always scan splash-screen theme resources; if Android 12+ could render a static splash icon blurry, include it as an Android Launch UX finding and allow it into Critical Findings / Prioritized Fixes when the evidence is concrete.
Out Of Scope In v1
Owned and deliberate scope choices — call out the limitation in the report rather than silently producing thin coverage:
- Material 3 compliance, theming, color/typography tokens — defer to the
material-3skill. - Accessibility scoring (
semantics, content descriptions, touch-target sizing) — flag obvious gaps as a note, do not score. - UI test coverage and Compose test rule patterns — note presence/absence, do not score; recommend
compose-agent focus on testingfor deeper review. - Compose Multiplatform-specific rules (
expect/actual, target-specific code paths) — note surface area and obvious platform-boundary risk; recommendcompose-agent focus on kmpfor deeper review. - Wear OS / TV / Auto / Glance surfaces — note obvious focus / keyboard / D-pad risk; recommend
compose-agent focus on focusfor deeper review. - Build performance (incremental compilation, KSP/KAPT choice).

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.

jetpack-compose-audit is a skill published in the GitHub repository hamen/compose_skill (367 stars, last pushed 1mo ago), licensed MIT. It adds 101 tokens to every session and 5,529 once invoked, about $0.0005 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.
