android-compose

android-compose is a skill for Claude Code, Codex from HoangNguyen0403/agent-skills-standard. It costs 48 tokens per session (540 once invoked), scanned A, original, MIT.

Guidance for building Android screens with Jetpack Compose, Android's declarative user-interface toolkit. It covers state handling, screen updates, lists, and side effects.

In plain words
What is it for?
Use it when writing Compose components, managing screen state, optimizing list rendering, or handling one-time actions and other side effects.
Why use it?
It helps avoid slow or unstable screens caused by unnecessary redraws, poorly managed state, or work running at the wrong time.

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-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 9d 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

Jetpack Compose Expert

Priority: P0 (CRITICAL)

Role: Android UI Performance Expert. Prioritize frame stability and state management.

1. Hoist State Correctly

  • Screen (Stateful) -> Content (Stateless).
  • Pass lambdas down (onItemClick: (Id) -> Unit).
  • NEVER pass ViewModel to stateless composables.
  • Use MaterialTheme.colorScheme, no hardcoded hex.

See implementation examples for state hoisting patterns.

2. Optimize Recomposition

  • Annotate params with @Stable or @Immutable.
  • Use key in LazyColumn items for stable identity.
  • Reuse or make Modifiers static where possible.
  • Use derivedStateOf for frequently updating derived values.

See implementation examples for derivedStateOf usage.

3. Handle Side Effects Properly

  • Use LaunchedEffect for one-shot or keyed side effects — never run side effects in composition body.
  • Move complex calculations to ViewModel or remember.

Anti-Patterns

  • No Side Effects in Composition Body: Use LaunchedEffect, not raw coroutines.
  • No VM Deep Pass: Hoist state; pass only data/callbacks.
  • No Heavy Computation in Composables: Offload to ViewModel or remember.

Verification

  • All stateless Composables have @Preview.
  • LazyColumn items use key parameter.
  • No ViewModel passed below Screen-level Composables.
  • ./gradlew build succeeds.

Files

What ships with it

2 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.

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.
