Skills Constitution
A cross-platform meta-rule set that forces an AI agent to check its installed skills before acting, load a matching skill when one exists, and search when none does, installable across Claude Code, ChatGPT, Cursor, and Gemini.
Skills Constitution is a set of governing rules, distributed as an installable skill or rule file, meant to sit above every other skill or tool an agent has. It defines a pre-check step that forces the agent to look at its capability registry before doing specialized work, a mandatory-use rule that requires loading a matching skill instead of falling back to a generic response, and a search-first rule for when no skill matches, with a deterministic classifier deciding whether a task counts as simple or specialized.
An install script detects the host platform and adapts: skill-directory platforms such as Claude Code get the skill copied in and their skill tree automatically rebuilt, including skills bundled inside plugins; rule-file platforms such as Cursor, Windsurf, or Cline get the rules written into their rule directory; and prompt-only platforms such as ChatGPT or Gemini get an extracted injection template to paste into custom instructions. An optional flag registers host hooks that enforce the rules automatically, with backup, rollback, and idempotent reinstallation.
The project is maintained primarily in Chinese, with an English README provided separately.
