Improve Skill Quality

Turn a failing or unconvincing evaluation into a targeted fix. The single most common mistake in this repo is rewriting skill prose in response to a verdict whose real cause was the eval, the fixtures, or the harness. Classify first, then fix.

When to Use

• An evaluation verdict is a regression, underpowered, or "no credible improvement".
• A skill wins in the isolated arm but not in the plugin arm, or is reported "not activated".
• /evaluate reports "Evaluation ran but produced no results".
• A skill scores well but costs too much (tokens, turns, wall time, plugin menu budget).
• Deciding whether to strengthen or retire a persistently weak skill.

When Not to Use

• Creating a new skill from scratch — use create-skill.
• Creating a new eval.yaml from scratch — use create-skill-test.
• Changing the harness itself (eng/skill-validator, eng/vally-adapter, evaluation*.yml).
