Evals Required

• Any PR that ADDS a skill, or CHANGES a skill's behavior, MUST include an eval scenario under evals/ that exercises that behavior — in the same PR.
• A skill change without a matching evals/ scenario is a blocking violation: request changes, do not merge.
• This applies to every skill that carries LLM-side judgment. "It's small" or "baseline already does it" is not an exemption here — the eval is the proof, and it ships with the change.
