Vally Tests Skill

Purpose

This skill authors Vally conformance tests for the four supported artifact kinds in this repository: prompts, instructions, agents, and skills. Each test exercises a documented behavior the artifact already claims and routes the result through an appropriate Vally grader so failures are explainable. Test authoring is bounded by a refusal taxonomy that keeps the skill out of adversarial, harmful, or policy-evasion territory.

The skill ships:

• A canonical authoring workflow used by both the Vally Test Author prompt and the Prompt Builder subagent.
• Per-kind reference files that enumerate every conformance check the skill knows how to express.
• A grader catalog that maps Vally CLI 0.4.0 grader types to the checks they fit.
• A safety refusal taxonomy with regex patterns the safety lint script consumes.
• Helper scripts and asset templates for stimulus emission, corpus import, and dedupe.
