Performance Profiling

Overview

Use this skill to identify true runtime hotspots and prioritize optimizations by measurable impact.

Scope Boundaries

• Use this skill when the task matches the trigger condition described in description.
• Do not use this skill when the primary task falls outside this skill's domain.

Shared References

• Profiling evidence rules:
  • references/profiling-evidence-rules.md

Templates And Assets

• Profiling report template:
  • assets/profiling-report-template.md
• Optimization priority matrix:
  • assets/optimization-priority-matrix-template.csv

Inputs To Gather

• Performance symptom and target path.
• Reproducible profiling environment.
• Relevant profiling tools and sampling strategy.
• Acceptable optimization risk constraints.

Deliverables

• Profiling report with hotspot evidence.
• Prioritized optimization backlog.
• Before/after impact validation plan.

Workflow

1. Capture profiling scope in assets/profiling-report-template.md.
2. Gather baseline profiler evidence.
3. Prioritize opportunities with assets/optimization-priority-matrix-template.csv.
4. Apply references/profiling-evidence-rules.md for decision quality.
5. Publish optimization plan and verification gates.

Quality Standard

• Hotspots are tied to specific code paths and user impact.
• Priority reflects impact, effort, and risk.
• Optimization decisions are evidence-backed.

Failure Conditions

• Stop when hotspots cannot be attributed to concrete paths.
• Stop when expected gains are speculative without evidence.
• Escalate when high-impact bottlenecks remain unresolved.
