FAQPage Schema
How do I write an AI skill that agents can discover and follow reliably?

Authoring reliable AI skills requires creating SKILL.md files with valid YAML frontmatter, concise guidance, and progressive disclosure to ensure agents discover and follow instructions accurately under pressure.

What is evaluation-driven development for AI agent skills?

Evaluation-driven development tests AI skills using baseline scenarios, pressure testing, and rationalization analysis to verify agent compliance and ensure operational reliability before deployment.

How do I structure SKILL.md frontmatter for prompt engineering workflows?

Structure SKILL.md frontmatter with required YAML name and description fields targeting discovery scenarios, ensuring prompt engineering workflows remain discoverable by AI agents.

Why do AI agents ignore skill documentation under pressure?

AI agents ignore skill documentation under pressure when it lacks explicit safeguards against common rationalizations and targeted evaluation scenarios to verify compliance.

Can I use evaluation scenarios to test existing SKILL.md files?

Yes, you can apply evaluation scenarios to existing SKILL.md files by running pressure testing and rationalization analysis to verify agent compliance and iteratively refine documentation.
