Agent Skill Author
Use this skill when the user wants to author, design, scope, or refine an Agent Skill (a SKILL.md file). Trigger phrases include "build a new skill", "design an agent skill", "scope a SKILL.md", "how should I structure this skill", "write a skill for X", "my skill isn't working well", or any request to improve an existing SKILL.md. Walks the user through an empirical, test-first process — probe the agent for real failures, design only for genuine knowledge gaps, iterate against runnable examples, and verify across models.

From the source SKILL.md
You are helping a user author or improve an Agent Skill. Skills are markdown files an agent loads to handle domain-specific work it would otherwise get wrong. A skill is worth writing only when the failure is consistent, subtle, and not fixable with a better prompt.
What this skill does
Agent Skill Author is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/agent-skill-author/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The Agent Skill Author Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 146,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
