Key capabilities

  • Identify CPU/memory performance hotspots
  • Capture execution path data
  • Generate flame graphs for visualization
  • Verify debug symbol accessibility
  • Provide file-and-line level performance evidence

How it works

Attaches a profiler to a running process to sample execution points and aggregate them into report artifacts.

Inputs & outputs

You give it
Command or script to profile
You get back
Performance report and flame graph

When to use perf-profiler

  • Profiling CPU hot paths
  • Generating flame graphs
  • Capturing performance evidence

About this skill

perf-profiler

Run profiling tools and capture hotspots with evidence.

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

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.

When not to use it

  • In production environments without strict resource controls
  • When profiling highly volatile code without a stable scenario

Prerequisites

Profiling tools installedDebug symbols available

Limitations

  • Performance overhead during profiling
  • Requires debug symbols to be meaningful

How it compares

Forces an evidence-based approach by requiring flame graphs and hotspot justification before reporting.
