What it does
Compose Performance is an agent skill from chrisbanes/skills. Use when investigating Jetpack Compose recomposition cost, compiler stability reports, skippability, unstable parameters, frame-rate State reads, cross-phase snapshot back-writing, or @ReadOnlyComposable contracts.
Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/composition-contracts.md`, `references/deferred-reads.md` and `references/diagnosis.md`).
It sits in Mobile, covering Android development. It works with Jetpack Compose. The repository describes itself as: Skills for Kotlin, Jetpack Compose, and Android development. The licence is Apache-2.0.
When your agent uses it
- Investigating Jetpack Compose recomposition cost
- Compiler stability reports
- Unstable parameters
- Frame-rate State reads
Example prompts
- “/compose-performance”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Reproduce one concrete transition and capture the observable evidence
- Classify the primary axis: parameter stability and skipping, State read
- Check for a false lead: a real data change, a correctness defect, or an
- Read the corresponding focused reference before proposing a change.
- For review work, pair every finding with the smallest evidence-supported
- Change one axis at a time and re-measure the same transition.
- Finish when the evidence improves at the observed boundary without hiding
What it can do on your machine
Read from SKILL.md and the folder at commit f872f97. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Compose Performance loads about 750 tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 364 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Compose performance
Core principle
Measure one user-visible transition, identify the runtime axis that causes the work, then apply the smallest correction at the phase or boundary where that axis begins.
Procedure
- Reproduce one concrete transition and capture the observable evidence: recomposition counts, compiler reports, profiler data, or a clear trace.
- Classify the primary axis: parameter stability and skipping, State read phase, or snapshot state written back into an earlier phase.
- Check for a false lead: a real data change, a correctness defect, or an unchanged lazy item that is expected to recompose.
- Read the corresponding focused reference before proposing a change.
- For review work, pair every finding with the smallest evidence-supported
repair. For a false stability promise, explicitly say to replace mutable
non-snapshot properties with immutable data or snapshot-observable state,
verify that contract, and only then decide whether an annotation remains
needed. For a phase problem, name the layout or draw consumer where the
changing read or calculation should move. A cross-phase write proves
invalidation or an extra pass; do not claim oscillation or an infinite loop
unless evidence shows values repeatedly changing. Do not stop at diagnosis.
When only source code is available, separate the proven feedback path from
its unmeasured runtime cost. Give a conditional repair direction based on
the intended measurement boundary; do not prescribe a callback swap,
equality guard, or content-layout rewrite as a performance fix without
evidence that it changes the observed problem. For an
Intheld inmutableStateOfwith the default structural equality policy, an unchanged value already avoids invalidation. - Change one axis at a time and re-measure the same transition.
- Finish when the evidence improves at the observed boundary without hiding state changes, caching stale values, or moving work to a less correct owner.

Can I use Compose Performance in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add chrisbanes/skills --skill compose-performance -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/compose-performance, .gemini/skills/compose-performance, .github/skills/compose-performance and .opencode/skills/compose-performance in your project.
What does Compose Performance need to run?
SKILL.md names no scripts, command-line tools or credentials: Compose Performance is instructions for the agent only.
Does Compose Performance access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Compose Performance safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
