Author and tier behavioral probes for a Triggers: "measure this skill", "the probe came back INERT", "the control arm aces it", "harden this scenario", "is this skill actually doing anything".

Tokens, turns and time describe resource use, not a dollar price.
This benchmark measured an earlier version of the skill.
One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
An evaluation of skill-regex-builder across 5 cases shows a +15% delta without confidence intervals. Should this sample be declared as proven statistical benefit or directional? Provide the formatted output summary.
| Checked | Without skill | With skill |
|---|---|---|
| The response classifies the small sample delta as directional. | Passed | Passed |
| The output includes the Uncertainty: section. | Missed | Passed |
The instructions your model reads when the skill loads.
Answer one named maintenance decision: retain, revise, remove, or insufficient evidence. Choose the measurement that can answer that decision, use the caller's accepted cases and resource envelope, make one scoped recommendation, and stop. A completed evaluation does not require a positive difference.
This is an optional specialist. The selected runner owns execution and bounds; native results own measurements; BD and Git retain their authority. Do not add a core skill, AO evaluation command, scheduler, dashboard, second tracker, or mandatory review merely to run an experiment.
| Caller decision | Measurement | What it can establish |
|---|---|---|
| Does a natural request load this skill? | An authorized available routing probe that observes loading; optionally claude plugin eval with a with-only tool_used: Skill grader when Claude is explicitly authorized | Natural-request loading on the observed host/catalog; not whether loading helps |
| Does supplied skill text change a specific observable act? | Behavioral probe with the available authorized Codex adapter in scripts/probe-skill.sh | Behavior change under forced source injection; not routing, correct code or productivity |
| Does the installed plugin change graded answers end to end? | claude plugin eval against its no-plugin baseline, only when explicitly authorized and available | Routing and content together on the selected cases |
