| name | codex-exec-delegate |
| description | Delegate coding tasks to a nested Codex CLI run using `codex exec --yolo -m gpt-5.3-codex -c model_reasoning_effort=xhigh`. Use when you want the current Codex agent to act as an orchestrator (plan/review/verify) while a separate worker session performs edits and runs tests. |
Codex Exec Delegate
Workflow
- Draft a
[CODEX TASK] packet (goal, constraints, files, validation, done criteria).
- Run a nested
codex exec worker with gpt-5.3-codex + model_reasoning_effort=xhigh.
- Verify independently with
git status, git diff, and the validation commands from the packet.
- If anything fails, re-run the worker with the failure output + a tightened packet.
Worker Command
Prefer stdin to avoid shell quoting issues:
REPO_ROOT="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
cat <<'PROMPT' | codex exec -C "$REPO_ROOT" --yolo -m "gpt-5.3-codex" -c "model_reasoning_effort=xhigh" -

Required output:
1) Changed files
2) Summary of changes
3) Commands/tests run + results

Guardrails
- Include in the worker prompt: "Do not run
codex or spawn sub-agents; implement directly."
- Keep scope minimal; avoid unrelated refactors.
- Never fabricate command output or test results.
