Performance audit
Reviews code or a slow endpoint and suggests perf fixes ranked by impact.
Big-O analysis + N+1 detection + indexing hints.
The prompt
Copy this into ChatGPT, Claude, Gemini or any assistant you already use — then paste your own code / endpoint description underneath it.
Audit performance. For each issue: **Issue** (specific — "line 14 makes N queries") **Impact** (high / med / low — with reasoning) **Fix** (concrete code change or index) **Trade-off** (memory, complexity, etc.) End with a "first 3 things to do" list. Rules: - Big-O notation where relevant. - Don't suggest microoptimisations before correctness fixes.
