Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing. Uses GPT-5.5 by default for state-of-the-art software engineering.
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
# Codex Skill Guide ## Running a Task 1. Default to `gpt-5.5` model. Ask the user in the normal conversation which reasoning effort to use (`xhigh`, `high`, `medium`, or `low`). User can override model if needed (see Model Options below). If `gpt-5.5` is unavailable in your environment, fall back to `gpt-5.4`. 2. Select the sandbox mode required for the task; default to `--sandbox read-only` unless edits or network access are necessary. 3. Assemble the command with the appropriate options: - `-m, --model <MODEL>` - `--config model_reasoning_effort="<high|medium|low>"` - `--sandbox <read-only|workspace-write|danger-full-access>` - `-a never` before `exec` for non-interactive runs - `--output-last-message <FILE>` when a clean final response file is needed - `-C, --cd <DIR>` - `--skip-git-repo-check` 3. Always use --skip-git-repo-check. …

How to install
mdr add dannykkh/skill-olympus/codex@sha256:4324408e085b33a3The line at the top of this page pins the label git:20260812.afc9950, 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.
