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 | $0.00046 | $0.00674 |
| Opus 5 | $0.00023 | $0.00337 |
| Sonnet 5 | $0.00009 | $0.00135 |
| Haiku 4.5 | $0.00005 | $0.00067 |
Grade A, and why
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 8d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Build Compose UI that is maintainable, state-driven, accessible and aligned with Material 3.
When to use
- Creating or refactoring a Compose screen.
- Connecting ViewModel and StateFlow to UI.
- Adding Navigation, previews, adaptive layouts or accessibility semantics.
Inputs to inspect
- Composable files, UI state and ViewModel.
- Theme/design system and Material 3 usage.
- Navigation graph and route parameters.
- Preview and UI test setup.
Required workflow
- Define UI state and user events.
- Create a Route composable for ViewModel and navigation wiring.
- Create a stateless Screen composable that renders state.
- Add previews for loading, empty, content and error states.
- Add semantics and tests for the critical flow.
Rules
- Use Route + Screen for stateful screens.
- Hoist state and keep reusable components stateless.
- Do not perform network, database or Firebase calls in Composables.
- Use Material 3 theme tokens.
- Add stable keys for lazy lists.

Common mistakes to avoid
- Passing ViewModel into reusable leaf components.
- Using remember for business state that belongs in ViewModel.
- Missing previews for error/empty states.
- Ignoring semantics, content descriptions and font scale.
What ships with it
4 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.

jetpack-compose is a skill published in the GitHub repository GDvega/super-android-kotlin-firebase-skill (2 stars, last pushed 2mo ago), licensed MIT. It adds 46 tokens to every session and 674 once invoked, about $0.0002 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.
