The **codex headless executor** does the bulk\nimplementation typing inside isolated\ngit worktrees. The vendored `cld` engine and driver under `scripts/` run\nin place -- no package install and no source checkout are needed.\nAn exact model ID is required; this provider has no default model. Pass `--executor codex:<model-id>@<effort>` explicitly. For requested fast mode, use `codex:gpt-6-luna@max+fast`; do not silently drop the tier.\n\nFor executor choices, run `python scripts/list_models.py --json` and follow\nthe picker section of `references/delivery-core.md`. Present exact returned\nIDs and supported efforts; discovery does not authorize dispatch.\n\n## When to use (and when not to)\n\n- **Use it** on a large build expressed as a plan of independently testable\n  slices with a dependency DAG, where executor tokens dwarf lead tokens.\n- **Do not use it** for small one-file fixes; the per-dispatch overhead only\n  pays off on large builds. Small work stays with Codex directly.\n\n## Ground rules\n\n- Respect the user's existing project instructions (AGENTS.md and friends).\n  Never install, overwrite, or replace them.\n- Preserve the user's exact executor/model/effort/tier selection. Present the\n  shortlist only when no selection exists; a listing is not dispatch permission.\n  Describe discovery only for the recorded host version and surface.\n- Never claim the provider's cost is free. Check that billed dispatches are\n  covered by the user's existing authorization; ask only if that is unclear.\n- For gate-4 repairs, follow the user's authorization and the host's active\n  approval policy. Never silently dispatch another paid attempt.\n- `--step` and validation make paid network calls through the executor CLI.\n  Check the active host permissions before dispatch. If network is disabled,\n  use the host's supported authorization flow; do not bypass its restrictions.\n  CLD blocks dispatch when `CODEX_SANDBOX_NETWORK_DISABLED=1` is set.\n\n## Drive the build\n\nRun these commands from the installed skill directory, using absolute plan and\ntarget-repo paths. The driver is vendored in this bundle. Prefer `--json` for\nmachine-checkable gates and act on the JSON `gate_code`. On Windows a shell\nwrapper (`pwsh -Command`) can report exit 1 for any non-zero driver exit, so\nthe JSON gate, not the shell's exit status, is authoritative.\n\n```bash\npython scripts/run_delivery.py <plan.md> --repo <dir> --dry-run --json  # preview layers\npython scripts/run_delivery.py <plan.md> --repo <dir> --step --workers 1 --executor <exact-spec> --validation-policy <deny|unmetered|allow> --budget-attempts <N> --json\npython scripts/run_delivery.py --status --repo <dir> --json             # cheap digest\npython scripts/run_delivery.py <plan.md> --repo <dir> --integrate --integration-tests <selector> --json\n```\n\nChoose the validation policy and cumulative attempt limit under the user's\nauthorization. Validation and retries count as dispatches. Prefer one worker\nfor a bounded sitting; the CLI default is four.\n\nExit codes: 0 ok, work remains; 2 failure/defer; 3 integrated and verified;\n4 lead repair required; 5 invalid plan/state or missing prerequisite;\n6 accepted work awaits integration.\n\n## References\n\n- `references/delivery-core.md` -- the shared, host-neutral gate (exit-code)\n  contract and authorization rules; identical in every host bundle.\n- `references/codex-workflow.md` -- the full Codex-led workflow: plan authoring,\n  batch-stepping, the model picker, gates, and the repair loop.\n- `references/provider-setup.md` -- install and verify the codex CLI.\n- `references/provider.md` -- codex executor specifics: locked\n  invocation, auth, cost, and platform notes.\n- [README.md](README.md) -- data handling, privacy, security reporting and a\n  no-inference reviewer preview of this bundle.\n"
