- →Recording latency measurements
- →Logging baseline vs experiment data
- →Documenting bottleneck findings
About this skill
perf-investigation-logger
Append structured investigation notes to {state-dir}/perf/investigations/<id>.md.
Follow docs/perf-requirements.md as the canonical contract.
Required Content
- Exact user quotes (verbatim)
- Phase summary
- Decisions and rationale
- Evidence pointers (files, metrics, commands)
Output Format
## <Phase Name> - <YYYY-MM-DD>
**User Quote:** "<exact quote>"
**Summary**
- ...
**Evidence**
- Command: `...`
- File: `path:line`
**Decision**
- ...
Constraints
- Use
AI_STATE_DIRfor state path (default.claude). - Do not paraphrase user quotes.
When not to use it
- →Logging non-performance related debugging notes
- →General project documentation
Prerequisites
Limitations
- →Requires adherence to the canonical perf-requirements.md contract
- →Limited to the defined output format
How it compares
It enforces a strict, standardized logging format for performance evidence, unlike unstructured manual note-taking.
