perf

perf

Rigorous performance investigation workflow. /perf enforces sequential benchmarks, minimum run durations, and evidence-backed decision-making.

Command

/perf

What it does

• Establishes a baseline and persists results under {state-dir}/perf/
• Runs controlled experiments one at a time
• Performs profiling and hotspot analysis
• Consolidates findings into a single baseline per version

Requirements

All behavior is governed by:

• docs/perf-requirements.md
• docs/perf-research-methodology.md

Inputs

• Hypotheses can be supplied via --hypotheses-file <path> during the hypotheses phase.

Skills

• perf-theory-gatherer - Hypothesis generation (git history + evidence)
• perf-code-paths - Code-path discovery before profiling
• perf-theory-tester - Controlled experiments for hypotheses
• perf-analyzer - Evidence-backed perf recommendations
• perf-investigation-logger - Structured log entries with evidence

Artifacts

• {state-dir}/perf/investigation.json
• {state-dir}/perf/investigations/<id>.md
• {state-dir}/perf/baselines/<version>.json
