Guides agents to create, validate, and optimize Agent Skills (SKILL.md) with best practices, frontmatter rules, and testing workflows.
Provides a comprehensive, standards-aligned reference for authoring high-quality SKILL.md files. It distills frontmatter rules, directory layout, progressive-disclosure patterns, script and references handling, and evaluation-driven workflows so agent authors and automation systems can produce skills that discover and execute reliably. Practical checklists and anti-patterns reduce common mistakes (bad names, wrong POV, oversized bodies).
Use this skill when an agent or human asks to create, edit, audit, or improve an Agent Skill or any reusable agent instruction package. Trigger on requests about "skills", "SKILL.md", "authoring", "validate skill", or when packaging workflows into reusable agent capabilities. Also useful when converting a manual workflow into a skill.
This guide targets agent authors for Claude Code, Claude.ai, and other agent platforms that follow the Agent Skills spec. It is platform-agnostic but includes Claude Code extended-field examples.
Skill SKILL.md body is null in DB and the source file (GitHub raw URL) returns 404 — the file appears to have been removed from the repository. No scripts were bundled. Unable to evaluate content, quality, or usefulness since there is nothing to review. Marking as very low quality due to missing content.
Source repo still exists but the skill file path (skills/other/other/agent-skills-authoring/SKILL.md) no longer exists in the repo tree. This is likely a stale DB entry from a deleted/moved file. Consider pruning or re-scraping.
