writing-skills

Skills are used for context that may be useful to a coding agent, without bloating LLM context when they are not relevant.

Skills are only worthwhile if the coding agent fails a task without the skill.

Skills live in /.agents/skills, with each skill having its own directory.

SKILL.md

Front matter

• Match the name to the directory name exactly.
• Write the description as "Use when - " in under 30 words and third person.
• Quote the description if it includes punctuation that could break YAML.

Markdown body

• Write concise instructions for the skill topic.
• Keep headings and bullet lists structured so readers can scan quickly.

Additional files

Other files, like scripts or data, may live in the directory and be referenced by the skill.
