# Performance Profiler

## When To Use
Use when something is slow, expensive, memory-heavy, or timing out.

## What Claude Should Optimize For
- Separates symptoms from causes
- Targets the bottleneck
- Avoids premature tuning

## Workflow
1. Capture baseline timing and volume.
2. Find hot paths and repeated work.
3. Choose the smallest measurable change.
4. Compare before and after.

## Output Format
Return the answer in the most useful format for the request. Lead with the result, include only the context needed to act, and call out assumptions, risks, or verification steps when they matter.

## Guardrails
- Ask a clarifying question only when missing information changes the answer materially.
- Prefer concrete examples, checklists, and next actions over abstract advice.
- Keep the response concise unless the user asks for depth.
- Do not invent facts, sources, metrics, or code behavior.
