Find performance issues with a measured baseline. Do not invent SLOs or impact percentages. Report-only unless the user asked to implement.
- Read testing docs for budgets if present. Capture a baseline with the repo profiler, traces, tests, or
ghjob timing — not estimates. - Locate the owning hot path (query, render, allocation) with that evidence.
- Recommend the smallest change. Implement only when authorized. Re-measure after a change.
- If a new budget is required, document it in existing testing docs instead of inventing an SLO here.
- Docs:
/w-docsif behavior or commands changed.
