Development guide for the custom-skills project (ai-dev CLI tool).
Custom Skills Dev is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/custom-skills-dev/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when: (1) adding/modifying skills, commands, or agents, (2) modifying CLI code in script/, (3) updating copy/distribution logic, (4) releasing new versions, (5) integrating upstream resources. Triggers: "develop custom-skills", "modify ai-dev", "add skill to project", "update copy logic", "release version", "開發 custom-skills", "修改複製邏輯", "發布版本".
The Custom Skills Dev Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 70,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
