Skill Creator

This skill provides guidance for creating effective skills.

Select the target host first

Before initializing or updating a skill, identify its intended discovery surface:

• Codex: default to $CODEX_HOME/skills or ~/.codex/skills. The bundled agents/openai.yaml metadata and Codex helper scripts apply.
• Claude Code: default to ~/.claude/skills when the user wants a personal Claude skill. A GLM Coding Plan endpoint changes the model provider, not Claude Code's skill directory. Do not require Codex UI metadata or Codex CLI commands unless the skill is also targeting Codex.
• GitHub Copilot or shared catalog: use the host-visible or repository path named by the user and follow that host's current discovery rules.
