Run one prompt through headless Codex and capture the result. Use when: wanting a one-shot `codex exec` run or CI step. Not for batches or retries.
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 Exec — one-shot runtime adapter Run exactly one caller-supplied Codex prompt as one process and capture its result. This skill does not choose work, retry, validate or continue. ## Rules that change the command - **Sandbox from declared effects.** `-s read-only` for review or analysis, `workspace-write` only for authorized edits, and network or wider access only when the caller explicitly requires those effects. "In case it needs it" is not a declared effect. `-s` limits only Codex's shell commands; the user's `config.toml` still starts its MCP servers. For review and CI add `--ignore-user-config` (auth still loads) and `--ephemeral`, or report the inherited MCP servers as undeclared effects. A permission denial inside the run (`EPERM`, "Operation not permitted") shows only what the mode blocks, not whether the host or the code would fail. Quote it and report the check as sandbox-limited under not run / `not_checked`: neither a pass nor a failed check. A host-side observation still stands; a host run is the caller's decision. - **Close stdin.** `codex exec` reads the prompt from stdin when no prompt …

How to install
mdr add boshu2/agentops/codex-exec@sha256:d1855a2ea7d1ffc6The line at the top of this page pins the label git:20261031.73cbeae, 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.
