codex-exec SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
codex-exec from boshu2/agentops is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

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. One prompt, one process, one captured artifact keeps every output byte traceable to one invocation. ## 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. - **Close stdin.** `codex exec` reads the prompt from stdin when no prompt argument is given, and appends piped stdin to a prompt argument. A non-TTY run (CI, a script) with an open stdin can wait forever: the **stdin hang**. Feed the prompt on stdin and let it end, or redirect `</dev/null`. - **One deadline, never renewed.** Fix one absolute deadline before the first attempt. Each invocation, including any retry the caller decides to make, gets only the time left before that deadline. A retry never gets a fresh budget: a loop that gives each attempt its own new timeout has silently …

How to install
mdr add boshu2/agentops/codex-exec@sha256:f50662be1f0d943dThe line at the top of this page pins the label git:20261010.407c70b, 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.
