compose-recomposition-performance

compose-recomposition-performance is a skill for Claude Code, Codex from costular/Minitask. It costs 65 tokens per session (365 once invoked), scanned A, a copy of compose-recomposition-performance, Apache-2.0.

Use when investigating Jetpack Compose recomposition performance, skippable/restartable composables, composables.txt or compiler reports, Layout Inspector recomposition counts, or frame-rate State reads in composition vs layout/draw, and it is not yet clear whether the cause is parameter stability or deferred reads.

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

compose-recomposition-performance 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 today.

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

Compose recomposition performance

Router only — deep fixes live in compose-stability-diagnostics and compose-state-deferred-reads.

Two axes

  1. Parameter stability / skipping — can Compose skip this restartable composable; are arguments stable and comparable?
  2. Where State is read — is frame-rate State read during composition vs layout/draw?

Either axis can dominate; they combine independently.

Route here → focused skill

Primary suspicion Next skill
Skipping, unstable params, compiler/composables.txt churn compose-stability-diagnostics
Frame-rate State read phase (composition vs layout/draw) compose-state-deferred-reads
Evidence for both Apply both skills in parallel

Review order

  1. Decide which axis fits the evidence; open the matching skill.
  2. If unclear, sample both — stability churn vs composition-phase reads of fast State.
  3. Re-measure after changes.

When NOT to apply

  • Recomposition tracks real data changes, or the bug is correctness not cost.
  • No profiler / compiler signal suggests a problem.
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.
