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 | $0.00063 | $0.01088 |
| Opus 5 | $0.00032 | $0.00544 |
| Sonnet 5 | $0.00013 | $0.00218 |
| Haiku 4.5 | $0.00006 | $0.00109 |
Grade A, and why
modern-jetpack-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 10d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review or generate Jetpack Compose code for correctness, modern API usage, and adherence to Android best practices. Report only genuine issues — do not nitpick style unless it contradicts a clear rule.
Review / Generation Process
When reviewing existing code, follow these steps in order:
- Check for deprecated or outdated APIs →
references/api.md - Review composable structure and composition patterns →
references/composables.md - Validate state management and data flow →
references/state.md - Validate side-effect usage →
references/effects.md - Check recomposition stability →
references/recomposition.md - Validate navigation implementation →
references/navigation.md - Check Material 3 / Expressive design compliance →
references/design.md - Validate accessibility →
references/accessibility.md - Check performance →
references/performance.md - Quick Kotlin code review →
references/kotlin.md - Final code hygiene check →
references/hygiene.md
When generating new code, load the relevant reference files for the feature being built before writing any code, so output is idiomatic from the start.
For partial reviews or targeted generation, load only the relevant reference files.
Core Instructions
- Target Compose BOM 2024.x by default. Note where BOM 2025.x (Material Expressive) introduces new components or APIs.
- Use Material 3. Do not use Material 2 unless the project already uses it.
- Architecture: MVVM with unidirectional data flow (UDF). ViewModel + StateFlow for screen state. Compose UI observes state, emits events.
- Target Kotlin with modern language features (sealed interfaces, coroutines, Flow).
- Do not introduce third-party libraries without asking first.
- Each composable should live in its own file for non-trivial components.
- Organize by feature, not by technical layer (screens/home/, screens/settings/, etc.).
Output Format
Organize findings by file. For each issue:
- State the file and relevant line(s).
- Name the rule being violated.
- Show a brief before/after Kotlin snippet.

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.

modern-jetpack-compose is a skill published in the GitHub repository anhvt52/jetpack-compose-skills (96 stars, last pushed 6mo ago), licensed MIT. It adds 63 tokens to every session and 1,088 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 2026-08-30.
