Skill Builder

If you're building Claude Code extensions or Agent Skills, this walks you through the complete workflow from clarification to validation. It references the actual specifications at agentskills.io and Anthropic's authoring best practices, then generates compliant SKILL.md files with proper frontmatter. The progressive disclosure guidance is solid: it explains what to load at startup versus on activation versus on demand. What I like is the blunt conciseness advice, challenging every paragraph to justify its token cost and keeping bodies under 500 lines. It also catches common mistakes like using deprecated frontmatter fields or writing time-sensitive content that goes stale.
