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

Synthesizes performance findings into evidence-backed recommendations for decision-making.

  • Helps developers turn performance investigation results into actionable insights.
  • Depends on logs and code as evidence sources for analysis.
  • Decides recommendations by evaluating baseline data, experiment results, and profiling evidence.
  • Presents results in a structured format with summaries, recommendations, and next steps.

# perf-analyzer

Synthesize performance investigation results into clear recommendations.

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

## Inputs

- Baseline data
- Experiment results
- Profiling evidence
- Hypotheses tested
- Breaking point results

## Output Format

```
summary: <2-3 sentences>
recommendations:
  - <actionable recommendation 1>
  - <actionable recommendation 2>
abandoned:
  - <hypothesis or experiment that failed>
next_steps:
  - <if user should continue or stop>
```

## Constraints

- Only cite evidence that exists in logs or code.
- If data is insufficient, say so and request a re-run.

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-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-profiler"Use when profiling CPU/memory hot paths, generating flame graphs, or capturing JFR/perf evidence."
perf-theory-gatherer"Use when generating performance hypotheses backed by git history and code evidence."
