# aieng-agent-skills

Agent behavior skills for the `.aieng` ecosystem. These are SKILL.md-based behavior contracts that tell an AI agent how to use the `.aieng` CLI and packages correctly. They are not execution code, not backends, and not part of the `aieng` runtime package.

Skills reference both but belong to neither. They version independently from both.
