What its author says it does

Copied from the file, not written here

Performance profiling workflow for CPU/memory/I/O hotspot localization and optimization prioritization. Use when regressions or inefficiencies require profiler-based evidence for optimization decisions; do not use for non-performance functional acceptance decisions.

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.
