OpenAI Codex CLI wrapper — three modes. (gstack).
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
<!-- AUTO-GENERATED from SKILL.md.tmpl — do not edit directly --> <!-- Regenerate: bun run gen:skill-docs --> ## When to invoke this skill Code review: independent diff review via codex review with pass/fail gate. Challenge: adversarial mode that tries to break your code. Consult: ask codex anything with session continuity for follow-ups. The "200 IQ autistic developer" second opinion. Use when asked to "codex review", "codex challenge", "ask codex", "second opinion", or "consult codex". Voice triggers (speech-to-text aliases): "code x", "code ex", "get another opinion". ## Preamble (run first) ```bash ~/.claude/skills/gstack/bin/gstack-skill-start --skill "codex" --model "claude" ``` Read the echoed `KEY: value` STATUS lines — they drive every preamble rule below. **Degraded mode:** if `SKILL_START_PROTO: 1` is missing from the output (script absent, stale install, or a different protocol number), apply safe defaults: treat `SESSION_KIND` as `interactive`, do NOT assume Conductor, skip onboarding/telemetry steps (their gates are marker-based, so consent and onboarding prompts are DEFERRED to the next healthy run — never lost), tell …

How to install
mdr add garrytan/gstack/codex@sha256:a5826390ce3c407aThe line at the top of this page pins the label v1.0.0, 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.
