Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Use when running controlled perf experiments to validate hypotheses.Key capabilities
- →Execute controlled performance experiments
- →Validate optimization hypotheses
- →Run benchmark validation passes
- →Record experiment results and deltas
How it works
The skill manages the experiment lifecycle by enforcing a clean baseline, applying a single change, running benchmarks, and recording the results.
Inputs & outputs
When to use perf-theory-tester
- →Validating optimization hypotheses
- →Benchmarking code changes
- →Running controlled performance regression tests
About this skill
perf-theory-tester
Test hypotheses using controlled experiments.
Follow docs/perf-requirements.md as the canonical contract.
Required Steps
- Confirm baseline is clean.
- Apply a single change tied to the hypothesis.
- Run 2+ validation passes.
- Revert to baseline before the next experiment.
Output Format
hypothesis: <id>
change: <summary>
delta: <metrics>
verdict: accept|reject|inconclusive
evidence:
- command: <benchmark command>
- files: <changed files>
Constraints
- One change per experiment.
- No parallel benchmarks.
- Record evidence for each run.
When not to use it
- →Running non-controlled or parallel benchmarks
- →General code testing
Prerequisites
Limitations
- →Strictly one change per experiment
- →No parallel benchmarking allowed
How it compares
It enforces a strict experimental methodology and output format, whereas manual testing often lacks consistent baseline management.
