A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Summarize impact from benchmark data without overstating it. Distinguish measured local overhead from behavior benchmarks that still need agent runs.
benchmarks/behavior-cases.json for behavioral test cases.npm run benchmark for local instruction and hook overhead.Use this shape:
Measured
- <metric>: <value>
Behavior cases
- <case>: expected rung <rung>; baseline risk <risk>
Limitations
- <what has not been measured yet>Never claim the ruleset reduces LOC, cost, or time until a baseline-vs-enabled agent run has actually been measured.
