Run the great_cto controlled Codex lifecycle with controller-owned writes, verifier evidence, human gates and optional artifact release.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Controlled Codex host Use the version-pinned npm entrypoint below. A Codex plugin install loads skills and MCP configuration, but it does not add the `great-cto` npm binary to `PATH`. Do not imitate Claude Code hooks or manually chain roles: the controller reads `shared/pipeline.toml`, persists the cursor and owns every write and gate transition. ## Preflight ```sh npx --yes great-cto@3.75.10 codex-host doctor npx --yes great-cto@3.75.10 codex-host list --dir /absolute/project ``` `doctor.state=blocked` means do not start. Docker may be unavailable when no checks/release policy is requested; GitHub CLI may be unavailable when the local adapter is used. The run store must not be group/world accessible. For mixed-host runs, also require `doctor.checks.claude.state=available`. ## Start Policies must be operator-owned absolute files outside the worker project. Allowed paths are explicit controller write boundaries. ```sh npx --yes great-cto@3.75.10 codex-host start \ --dir /absolute/project \ --prompt "the requested outcome" \ --allow src,tests,docs \ --checks-policy /absolute/operator/checks.json \ --release-policy /absolute/operator/release.json ``` …

How to install
mdr add avelikiy/great_cto/codex-host@sha256:3af1be9cbe82497bThe line at the top of this page pins the label git:20261102.fbc28a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
