android-patterns

android-patterns is a skill for Claude Code, Codex from hanamizuki/solopreneur. It costs 69 tokens per session (483 once invoked), scanned A, original, MIT.

A collection of solutions for recurring Android Jetpack Compose interface problems. Jetpack Compose is Android's toolkit for describing screens with Kotlin code.

In plain words
What is it for?
Use it when building Compose previews, charts, bottom navigation, modal sheets, swipe-to-dismiss views, rounded clickable elements, or locale-aware dates.
Why use it?
It helps avoid common layout, scrolling, preview, touch-feedback, transparency, system-bar, and date-formatting mistakes.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

android-patterns 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 5d 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.

What it actually says

Android / Jetpack Compose Patterns

A curated collection of non-obvious patterns that solve recurring issues in Jetpack Compose apps. Each reference is self-contained — load only the one(s) relevant to the task.

When to load which reference

Decide by the symptom or the task at hand, then read the matching reference before writing code.

Task / Symptom Reference
Writing a new @Preview, preview is blank, or any preview question references/compose-preview-overview.md — start here (it branches to solutions/debugging/charts)
Preview involves Vico charts, CartesianChartModelProducer, or complex chart logic references/compose-preview-charts.md
Designing Scaffold + BottomNavigationBar + TopAppBar with edge-to-edge / status bar references/scaffold-bottom-nav.md
Content inside ModalBottomSheet jitters when scrolled to top references/bottomsheet-scroll.md
Ripple on a rounded/shaped clickable is rectangular or spills past corners references/compose-ripple-clipping.md
SwipeToDismissBox — background indicator bleeds through semi-transparent content references/swipe-to-dismiss-transparent.md
Displaying user-facing dates across locales (MM/DD vs DD/MM, MIUI locale quirks, i18n) references/date-format-localization.md

How to use these patterns

These references describe patterns, not project-specific conventions. Examples use AppTheme and generic identifiers — substitute the host project's theme (MojoTheme, YourAppTheme, etc.) and domain types when applying. The principles transfer directly.

If the host project already has an established pattern that contradicts a reference, follow the host project. Use these references for greenfield code or when a known issue matches the described symptom.

Changes

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.
