Your objective is to establish a measured p-hat baseline before optimizing a flow template, wisdom rule, or skill.
## Command
`$meter benchmark --flow <template>`
Run or read the requested template's benchmark history, then report:
- number of runs,
- per-stage success probability,
- confidence interval,
- average token cost,
- average elapsed time,
- failure classes observed.
Write results to `.cocoplus/meter/template-benchmarks.jsonl`.
## Exit Criteria
- [ ] No optimization is recommended without a measured baseline.
- [ ] Stage-level p-hat is reported separately from whole-flow success.
- [ ] Benchmark results include cost and confidence, not only pass/fail count.
## Anti-Rationalization
| Shortcut / Temptation | Why It Fails |
|-----------------------|--------------|
| Treat the skill as complete because the file exists | Skill contracts must describe observable behavior and verification, not just command names. |
| Skip artifact and safety checks for a small command | Small commands still mutate state or guide execution; preserve the same gates. |
