ThumbGate Operator Lab is a free community for operators using Claude Code, Codex, Cursor, Gemini, Amp, OpenCode, and MCP tools in real repos. Bring one repeated AI-agent failure. We turn it into a prevention rule, pre-action gate, or workflow-hardening teardown. Start locally: npx thumbgate init Weekly rhythm: Monday: repeated-agent-failure thread Wednesday: live rule teardown Friday: Workflow Hardening Sprint office hours
