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 | $0.00090 | $0.01358 |
| Opus 5 | $0.00045 | $0.00679 |
| Sonnet 5 | $0.00018 | $0.00272 |
| Haiku 4.5 | $0.00009 | $0.00136 |
Grade A, and why
android-kotlin-compose 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.

REVIEW MODE
Trigger phrases: "audit this file", "check this composable", "review this screen", "review mode", "a11y pass on this composable".
When triggered, silently run this 6-point checklist on the target file before responding. Cite failures by checklist number and banned-antipattern row from ../../references/00-banned-antipatterns.md.
| # | Check | Fail if |
|---|---|---|
| 1 | Modifier param | Missing modifier: Modifier = Modifier or not last optional param |
| 2 | State hoisting | Screen/business state inside @Composable that belongs in ViewModel |
| 3 | Lazy list keys | LazyColumn/LazyRow items missing key = {} or contentType = {} |
| 4 | Lifecycle collection | Uses collectAsState() instead of collectAsStateWithLifecycle() |
| 5 | Side effects in composition | IO, DB, network, or viewModelScope work directly in composable body |
| 6 | Stability | Data class params to child composables lack @Stable or @Immutable |
Output format for REVIEW MODE:
## Compose audit — <filename>
| # | Status | Finding |
|---|--------|---------|
| 1 | PASS/FAIL | ... |

### Banned antipatterns hit

Load ../../references/17-accessibility.md when audit includes TalkBack, touch targets, or contrast.

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.

android-kotlin-compose is a skill published in the GitHub repository haidrrrry/compose-kotlin-agent-skills (47 stars, last pushed 2mo ago), licensed MIT. It adds 90 tokens to every session and 1,358 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.
