Codex handoff

This is JMO's standalone handoff skill. It is not gstack's /codex skill and does not require gstack.

Prepare the task

Check command -v codex and codex exec --help. If missing, direct the user to https://developers.openai.com/codex/cli/ and explain that they must install and sign in to Codex. Do not claim a handoff ran when the CLI is unavailable.
Read the repository instructions and inspect git status --short. Identify the working directory, requested mode (review, advice, or implementation), allowed files, and acceptance criteria. Default to read-only review when the request does not authorize edits.
Write a focused prompt containing the user's task, relevant paths, constraints, and required checks. Include enough context for a separate agent without passing credentials or unrelated private material. Tell Codex which files are already modified and to preserve those changes.

Run Codex

Use the user's configured model. Pass the prompt through stdin or a quoted heredoc, not interpolated shell text. Replace the example directory with the actual absolute project path:

codex exec --sandbox read-only --cd '/absolute/project/path' - <<'TASK'
Review the specified changes. Do not edit files. Report actionable findings with file locations, evidence, and uncertainty. Follow the repository's instructions.
