# perf-profiler
Run profiling tools and capture hotspots with evidence.
Follow `docs/perf-requirements.md` as the canonical contract.
## Parse Arguments
```javascript
const args = '$ARGUMENTS'.split(' ').filter(Boolean);
const tool = args[0] || '';
const command = args.slice(1).join(' ');
```
## Required Rules
- Verify debug symbols before profiling.
- Capture file:line for hotspots.
- Provide flame graph or equivalent output when possible.
## Output Format
```
tool: <profiler>
command: <command>
hotspots:
- file:line - reason
artifacts:
- <path to flame graph or profile>
```
## Constraints
- No profiling without a clear scenario.
- Keep outputs minimal and evidence-backed.More Performance skills
