Read and apply to the current task, citing rule IDs/rows with one line of evidence as they fire:

  • docs/guardrails/PERFORMANCE.md — PERF1–PERF6 (PERF3: no speed claim without before/after numbers)
  • docs/guardrails/TRAPS-SQL.md — "Indexes, types, pagination" rows
  • docs/guardrails/TRAPS-NOSQL.md — Redis rows (SCAN, TTL)
