codex-cli skillA
codex-cli is agent-read markdown (skill) from cowork-os/cowork-os: Run OpenAI Codex CLI as a background agent — detect, install, configure, and execute tasks via codex exec..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# codex-cli ## Purpose Detect, install, configure, and run the OpenAI Codex CLI (`codex`) as an autonomous background agent for code editing, PR review, issue fixing, and one-shot automation tasks. ## Routing - Use when: User wants to run Codex CLI, asks for "codex agent", "spin up codex", "codex review", "codex fix", or wants to execute a coding task using the OpenAI Codex CLI specifically. - Do not use when: The request is for planning, discussion, or non-executable output. - Outputs: Task result from Codex CLI agent, or setup instructions if CLI is not installed/configured. - Success criteria: Codex CLI executes the requested task and returns output, or user is guided to install/configure it. ## Trigger Examples ### Positive - "Spin up a Codex agent to review PR #55" - "Use Codex CLI to fix this bug" - "Run codex on this issue" - "Launch a codex agent" - "codex exec: add error handling to the API" ### Negative - "Review this code" (generic — doesn't specify Codex CLI) - "Explain how Codex works" (no execution needed) - "Write a plan for this feature" (planning only) ## Runtime Prompt - Runtime prompt is defined directly in `../codex-cli.json`.
