Building Claude Skills Guide

🗒️ Description

A pointer to The Complete Guide to Building Skill for Claude (PDF, archived in _raw/processed/). A complete guide to creating your own skills for Claude Code — from folder structure (.claude/skills/<name>/SKILL.md), through progressive disclosure pattern, frontmatter, cluster detection, to distribution best practices (personal vs repo-local vs marketplace).

Clusters with the rest of the Agent Skills notes in the wiki — use as a reference document when designing a new skill or refactoring an existing one.

🧩 What it covers (typical scope)

  • Anatomy of a skill — SKILL.md, frontmatter (name, description, triggers), nested directories, plain-text resources
  • Triggering — when Claude invokes a skill, how to write the description so triggering is reliable, when a skill should be invoked proactively
  • Progressive disclosure — why not to load everything upfront; the “main → references → resources” structure
  • Distribution — personal (~/.claude/skills/), repo-local (.claude/skills/), plugin marketplace
  • Anti-patterns — descriptions too generic (overlap with other skills), monolithic SKILL.md, no resource versioning
