    About this skill

    ThumbGate checks a tool call before it runs. A detected secret is a deny. A repeated lesson failure is a deny. A warning is not permission to continue.

    The zip is a SKILL.md for Claude Code, Cursor, Codex, Copilot, and any agent that reads the open skill format. It uses the public package thumbgate at version 1.37.2. Hosted ThumbGate Pro, the shared lesson history and dashboard, is a separate subscription and is not this file.
