Included Skills1

instruction-writingskills/instruction-writing/SKILL.md

Write, edit, audit or review an instruction file for an AI agent. Covers CLAUDE.md at user, project and local level, AGENTS.md for Codex, .claude/rules/ files, SKILL.md bodies, reference files under a skill, system prompts for an agent, and briefs for subagents. Ten rules, each with its reason, plus a rubric a fresh agent can run as an independent review. Use it whenever the user creates or touches any of those files, asks why an agent ignored a rule, asks what belongs in CLAUDE.md versus a skill, or asks to trim, tighten or rewrite agent instructions, even mid-task. Reply language and tone stay in the user CLAUDE.md. The skill test loop stays with skill-creator.
