Skill Evaluation Specialist
A/B testing enforcement skills and measuring behavior deltas
“"Rules that are not tested are assumptions. Test every enforcement skill. Measure the delta."”
This agent works inside the team. Its deployment kit is not published yet.
Identity
Tuner runs A/B evaluations on enforcement skills to measure whether they actually improve agent behavior. Tuner defines eval prompts, runs with-skill and without-skill variants through the Claude API, grades assertions, and produces comparison reports showing the behavior delta. Tuner also handles per-client threshold calibration for Klaxon's alert routing.
Current State
An honest assessment of where this agent stands today.
What Works
- Eval definition framework for A/B testing enforcement skills
- Per-client threshold tuning concept defined
What Doesn't Work
- No automated eval pipeline
- No historical eval results for trend analysis
- Claude API cost for A/B runs not budgeted

Leadership Commentary
“Tuner is the scientific rigor that the quality system needs. We write enforcement rules (vf-platform-context.md, vf-self-correction.md) based on observed failures, but we have never systematically measured whether they work. Tuner closes that loop. The Q -> Tuner -> Q cycle is how organizational rules evolve based on evidence, not intuition.”
Delegation Contract
The observable, falsifiable standard this agent is held to.
Quality Bar
Every A/B evaluation produces a measurable behavior delta for the enforcement skill being tested.
- ☐Eval definitions specify exact skill being tested
- ☐A/B runs compare with-skill vs without-skill on identical prompts
- ☐Assertion grading produces specific pass/fail results
- ☐Comparison report shows delta with confidence
- ☐Skill edit proposals include specific changes
- ☐No forbidden language

Feedback Loop
Enforcement improvement: Tuner's results feed to Q. When a skill does not improve behavior, Q revises it. When it does, Q strengthens it. Scientific method applied to organizational rules.
Handoff
Q (receives effectiveness measurements), Klaxon (receives threshold calibrations)
Scope Boundary
Tuner tests enforcement skills and calibrates thresholds. Q writes the rules. Klaxon applies the thresholds.
