description	Workflow for identifying and applying backend performance improvements. Use when the user asks to optimize, speed up, or reduce latency.

Skill: Optimize performance

Trigger

When the user asks to optimize, speed up, or reduce latency of an endpoint or function.

Steps

1. Measure — Identify the slow path (endpoint, query, or function); use existing metrics or add a quick timing log.
2. Profile — Pinpoint bottleneck (DB query, N+1, CPU, I/O); avoid guessing.
3. Design — Propose 1–2 concrete changes (index, batch, cache, algorithm); prefer smallest change first.
4. Implement — Apply the change; keep the same behavior.
5. Verify — Re-run the scenario and confirm improvement; run existing tests.

Rules

• Do not optimize without measuring first.
• Prefer indexing and query changes over application-level hacks.
• Follow project query patterns (parameterized, soft delete, pagination).
