Perf Theory Gatherer
When you need to figure out why something is slow but don't want to guess, this skill forces a structured approach. It digs through git history and maps out relevant code paths before generating up to five performance hypotheses, each tagged with evidence and a confidence level. The key constraint is useful: it won't let you jump straight to optimization suggestions. You get theories backed by actual commits and file references, not hunches. It follows a documented contract in perf-requirements.md, so if you're working with a team that needs reproducible performance investigation, this keeps everyone on the same methodology.

Generate performance hypotheses for a specific scenario.
Follow docs/perf-requirements.md as the canonical contract.
Required Steps
- Review recent git history (scope to relevant paths when possible).
- Identify code paths involved in the scenario (repo-map or grep).
- Produce up to 5 hypotheses with evidence + confidence.
Output Format
hypotheses:
- id: H1
hypothesis: <short description>
evidence: <file/path or git change>
confidence: low|medium|high
- id: H2
...
Constraints
- MUST check git history before hypothesizing.
- No optimization suggestions; only hypotheses.
- Keep to 5 hypotheses maximum.
