perf-profiler

$npx mdskill add ComposioHQ/awesome-claude-plugins/perf-profiler

Run profilers to capture CPU and memory hotspots with evidence.

  • Identifies performance bottlenecks in code execution paths.
  • Requires debug symbols and specific profiling scenarios.
  • Executes tools to generate flame graphs and evidence files.
  • Delivers minimal outputs with file:line locations and artifacts.

# perf-profiler

Run profiling tools and capture hotspots with evidence.

Follow `docs/perf-requirements.md` as the canonical contract.

## Required Rules

- Verify debug symbols before profiling.
- Capture file:line for hotspots.
- Provide flame graph or equivalent output when possible.

## Output Format

```
tool: <profiler>
command: <command>
hotspots:
  - file:line - reason
artifacts:
  - <path to flame graph or profile>
```

## Constraints

- No profiling without a clear scenario.
- Keep outputs minimal and evidence-backed.

SkillDescription
add-subSubscribe to a skill event. Adds a subscription that injects context before or after a skill runs. Supports optional conditions at both insert-level (inherited by all subscriptions) and subscription-level (AND-stacked). Conditions include fileExists, gitBranch, envSet, envEquals, fileContains (with optional regex).
helpShow skill-bus overview, status, and available commands. Quick reference for all skill-bus features.
list-subsList all active skill-bus subscriptions across global and project scopes, showing merge status, insert-level and subscription-level conditions, effective condition stacking, and what would fire for each skill.
pause-subsTemporarily disable the skill bus. Quick toggle to stop all subscriptions from firing without removing them.
perf-analyzer"Use when synthesizing perf findings into evidence-backed recommendations and decisions."
perf-baseline-manager"Use when managing perf baselines, consolidating results, or comparing versions. Ensures one baseline JSON per version."
perf-benchmarker"Use when running performance benchmarks, establishing baselines, or validating regressions with sequential runs. Enforces 60s minimum runs (30s only for binary search) and no parallel benchmarks."
perf-code-paths"Use when mapping code paths, entrypoints, and likely hot files before profiling."
perf-investigation-logger"Use when appending structured perf investigation notes and evidence."
perf-theory-gatherer"Use when generating performance hypotheses backed by git history and code evidence."
