perf-profiler

Run profiling tools and capture hotspots with evidence.

Follow docs/perf-requirements.md as the canonical contract.

Parse Arguments

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.
