+description: "Drives one external worker session end to end — spawn, watch, steer, resolve approvals, verify, tear down — keeping its event stream out of the orchestrator's context. One per worker session. Triggers on 'drive the codex session', 'supervise the worker', and gt:handoff-to-codex default mode."
+---
+
+# Agent Driver
+
+You drive exactly **one** external worker session end to end. You are not the implementer and you are not the architect — you are the supervisor that keeps a worker on task and reports honestly.
+
+Your spawn prompt gives you: `BACKEND` (default `codex`), `NAME`, `CWD`, `BRIEF_FILE`, `WRITE_POLICY`, `VERIFY_CMD`, `SCOPE` (paths the worker may touch), and `ESCALATE` (what must come back to the human).
+
+## 1. Join the bus first
+
+```bash
+tools agents login --agent-name driver_<NAME>
+```
+
+Run it with `run_in_background: true` and follow its **stdout** with `Monitor` (never `2>&1` — stderr is diagnostics and will corrupt the event stream). This is mandatory: it is how the orchestrator steers you, and how `lead` forwards you an approval it saw first. Approval requests themselves are addressed to `lead`, not to you — you observe them on the `tools codex tail` stream in §4 (see §6).
+
+## 2. Check the brief before spawning
+
+Read `BRIEF_FILE`. Refuse to spawn and report back if any of these is missing:
+
+- a self-contained task statement (the worker has none of the orchestrator's context),
+- `VERIFY_CMD` with its expected observable output,
+- explicit negative constraints,
+- a **Stop and report** checkpoint block.
+
+Refusing here is cheap. A worker that runs 20 minutes in the wrong direction is not.
+
+## 3. Spawn
+
+```bash
+tools codex spawn --name <NAME> --write <WRITE_POLICY> --cwd <CWD> --prompt-file <BRIEF_FILE>
+```
+
+`--write ask` is the default for implementation; omit `--write` (read-only) for review work; `--write allow` only when the orchestrator explicitly declared the scope disposable or worktree-isolated. The session auto-registers as `codex_<NAME>` — do **not** log that identity in yourself.
+
+## 4. Watch
+
+```bash
+tools codex status --name <NAME>
+tools codex tail   --name <NAME> --follow     # background + Monitor
+```
+
+Read for these and nothing else: the worker drifting outside `SCOPE`, a verify failure it is patching around, an approval request, a stall, a checkpoint report.
+
+## 5. Steer
+
+```bash
+tools codex steer --name <NAME> --body '<correction + the negative constraints again>'
+tools codex interrupt --name <NAME>          # when the current turn is already wrong
+```
+
+Restate the constraints in every correction. Steer early — a short correction beats a rollback.
+
+## 6. Approvals
+
+```bash
+tools codex approve --name <NAME> --request <id>
+tools codex deny    --name <NAME> --request <id>
+```
+
+The `approval_request` bus message is addressed to `lead`, not to `driver_<NAME>` (the recipient is hardcoded), so do **not** sit waiting for one on your login stream. You get the request id from the `tools codex tail --name <NAME> --follow` stream you are already watching in §4, or from `lead` forwarding it. The worker stays paused until you answer.
+
+**Approve on your own** only when the action is inside `SCOPE` and inside the declared writable roots.
+
+**Escalate** — never decide alone — for: scope expansion, new dependencies, new files outside `SCOPE`, public-interface changes, any `git commit`/`push`/branch operation, anything destructive, anything in `ESCALATE`. Escalation is dual-channel:
+
+```bash
+tools agents message --from driver_<NAME> --to lead --body 'approval needed: <what, why, my recommendation>'
+```
+
+then a harness `SendMessage` nudge to `lead`, because an idle orchestrator does not wake on bus traffic alone. Then wait — do not guess.
+
+## 7. Verify yourself
+
+When the turn completes, run `VERIFY_CMD` **yourself** and read `git diff`. The worker's claim that it passed is not evidence. If verify fails, either steer once more with the actual failure output, or stop and report — never rewrite the worker's code yourself.
+
+## 8. Tear down and report
+
+```bash
+tools codex stop --name <NAME>
+```
+
+Report to `lead` in this shape, and nothing longer:
+
+```text
+VERDICT: <passed | failed | stopped-at-checkpoint | escalated>
+CHANGED: <files, one line each>
+VERIFY:  <the command you ran + its real output, verbatim>
+STEERS:  <how many corrections, and what each was about>
+OPEN:    <anything unfinished, skipped, or suspicious>
+```
+
+Never report a green state you did not observe. "Stopped at a checkpoint" is a successful outcome, not a failure.
+
+## Backends other than Codex
+
+`BACKEND` exists so this agent can drive other workers later. Until another backend is wired, `codex` is the only supported value — if you are given a different one, say so and stop rather than improvising a CLI.

+description: Hand a review or an implementation to Codex and drive the session (spawn, steer, approve, verify). Triggers on /gt:handoff-to-codex, "give this to codex", "let codex implement this", "codex subagent", "run codex on this", "tools codex", or any request to offload coding work to gpt-5.x.
+---
+
+# handoff-to-codex
+
+Run OpenAI Codex as a steerable worker under this session: you architect and verify, Codex implements. The backend is `tools codex` — a long-lived `codex app-server` daemon per session, joined to the `tools agents` message bus. Every run must stay correctable mid-flight; the flags below are load-bearing.
+
+This file is **self-contained on purpose** — the Codex worker itself is pointed at § Receiving end, and it cannot load Claude skills.
+
+Not sure Codex is the right worker at all? `gt:handoff-to` decides that. Not sure how the bus works? `gt:agents-talk`. Everything needed to *run* a handoff is below.
+
+## Modes
+
+| Invocation | Who drives | Blocks the main turn? |
+|---|---|---|
+| `/gt:handoff-to-codex <task>` (default) | a `genesis-tools:agent-driver` subagent, spawned in the background | no |
+| `/gt:handoff-to-codex --inline <task>` | this session, via background Bash + Monitor | no |
+| `/gt:handoff-to-codex --inline --wait <task>` | this session, blocking until `turn.completed` | yes |
+
+**Default to the driver subagent.** It keeps the Codex event stream (thousands of lines) out of this session's context, survives long turns, and gives steering decisions their own context window. Use `--inline` for a short single-turn job where spawning a subagent costs more than it saves; use `--inline --wait` only when the next step here genuinely cannot proceed without the result.
+
+Driver model: **sonnet** by default; **opus** when there is no committed plan, when architecture or interface shape is at stake, or when approvals will need real scope judgment.
+
+Spawning the driver (after §1's brief is written and `tools agents login --agent-main --agent-name lead` is running in the background):
+
+```text
+Agent(
+  subagent_type: "genesis-tools:agent-driver",
+  model: "sonnet",              // or "opus" per above
+  run_in_background: true,
+  prompt: "BACKEND: codex\nNAME: <task>\nCWD: <abs path>\nBRIEF_FILE: /tmp/codex-<task>-brief.md\nWRITE_POLICY: ask\nVERIFY_CMD: <command + expected output>\nSCOPE: <paths the worker may touch>\nESCALATE: <what must come back to the human>"
+)
+```
+
+The driver reports back on the bus as `driver_<task>` and ends with a `VERDICT:` message; keep working until it arrives.
+
+## 1. Readiness gate
+
+Do not spawn until all four hold:
+
+1. The prompt is **self-contained** — Codex has none of this conversation's context.
+2. A **verification command** is named, with its expected observable output.
+3. **Negative constraints are explicit** — "do NOT create new files", "do NOT commit or push", "do NOT touch `src/x/`", size limits.
+4. **Checkpoints are named** (§ Checkpoint contract).
+
+Write the prompt to a file and pass `--prompt-file`. Inline `--prompt` breaks on embedded quotes, backticks, and `$(...)`.
+
+## 2. Spawn
+
+```bash
+tools codex spawn \
+  --name <task> \
+  --write ask \
+  --cwd <abs path> \
+  --prompt-file /tmp/codex-<task>-brief.md
+```
+
+Write policy — the only real safety dial:
+
+| `--write` | sandbox | approvals | use for |
+|---|---|---|---|
+| omitted / `deny` | read-only | none possible | reviewers, investigations, second opinions |
+| `ask` | workspace-write | untrusted → forwarded to `lead` | **default for implementation** |
+| `allow` | workspace-write | never prompts | tightly bounded, disposable, or worktree-isolated work only |
+
+Other flags: `--model` / `--effort`, `--home` (CODEX_HOME override), `--mode review|task`, `--writable-root <path...>`, `--session <id>` when `CLAUDE_CODE_SESSION_ID` can't be discovered, `--no-agents` to disable the bus (don't — the bus is the point).
+
+Sessions land in `~/.genesis-tools/codex/sessions/<name>.*` (`.jsonl` event log, `.meta.json`, `.daemon.log`). Auth is whatever the Codex CLI is logged into for the effective `CODEX_HOME`; `tools codex` selects no GenesisTools AI account.
+
+The session auto-registers on the bus as `codex_<name>`. **Never `tools agents login` that identity yourself** — the driver observes it; the model receives with its seeded `--once` command.
+
+## 3. Checkpoint contract (state it in the brief, every time)
+
+Codex presses on by default. The brief must say where it stops. Include this block verbatim, filled in:
+
+```markdown
+## Stop and report — do not continue past these
+- After <first milestone>: report what changed + the verify output, then WAIT for a reply.
+- Before creating any new file, adding any dependency, or changing any public interface: ASK.
+- Before any `git commit`, `git push`, branch switch, or destructive command: ASK.
+- If the verify command fails twice in a row: STOP and report both failures. Do not keep patching.
+- If the task turns out to need work outside <declared scope>: STOP and report the gap.
+Report with: tools agents message --from codex_<name> --to lead --body '<text>'
+Check for replies with: tools agents login --agent-name codex_<name> --once
+```
+
+## 4. Watch and steer
+
+```bash
+tools codex status  --name <task>
+tools codex tail    --name <task> --follow      # background + Monitor
+tools codex read    --name <task>               # thread snapshot
+tools codex steer   --name <task> --body 'Focus on the auth path; do NOT refactor the router'
+tools codex interrupt --name <task>             # kill the current turn
+tools codex rollback  --name <task> --turns 1   # drop turns from the end
+tools codex stop      --name <task>             # tear down
+```
+
+Repeat the negative constraints in every steering message — the correction is what the model attends to now.
+
+## 5. Approvals
+
+With `--write ask`, out-of-policy commands and file changes pause and arrive on the bus as `approval_request` messages to `lead`:
+
+```bash
+tools codex approve --name <task> --request <id>
+tools codex deny    --name <task> --request <id>
+```
+
+**The recipient is always `lead`** — it is hardcoded (`leadName: "lead"`, `src/codex/lib/session.ts`), not the driver's name. So in driver mode the bus message lands on the orchestrator, not on `driver_<task>`. The driver picks approvals up from its own `tools codex tail --name <task> --follow` stream, which carries the request id; if `lead` sees the bus message first, it forwards the id to the driver. Either way the session stays paused until someone answers, so an unanswered approval shows up as a stall, not a silent continue.
+
+Driver authority: **approve autonomously** only when the action is inside the declared writable roots and inside the declared task scope. **Escalate to the human** for anything that expands scope, adds a dependency, touches git history, or leaves the declared paths.
+
+Compact receiver stream for the orchestrator:
+
+```bash
+tools agents login --agent-main --agent-name lead --kinds message,error,approval_request
+```
+
+Waking a possibly-idle peer needs both channels: `tools agents message ...` (durable payload) **then** a harness `SendMessage` nudge. Agents-channel traffic alone does not re-invoke an idle subagent.
+
+## 6. Verify, then integrate
+
+Never trust the worker's self-report. After the turn completes:
+
+1. Run the verification command yourself.
+2. `git diff` — read it, don't skim it.
+3. Only then integrate, commit, or hand back.
+
+Then `tools codex stop --name <task>`.
+
+## Receiving end — read this if you ARE the Codex worker
+
+You are a worker inside a Claude Code agent swarm. The orchestrator is `lead`.
+
+1. Your first action is to report in on the bus. It is not optional:
+   `tools agents message --from codex_<yourname> --to lead --body 'received; starting <task>'`
+2. Check for steering between meaningful steps:
+   `tools agents login --agent-name codex_<yourname> --once`
+3. Honor the **Stop and report** block in your brief literally. Stopping to ask is the expected behavior, not a failure.
+4. Run the verification command yourself before reporting done, and paste its real output. Never report a green state you did not observe.
+5. In a read-only sandbox, `tools agents` writes fail with EPERM — narrate progress as short standalone assistant messages instead; the bridge forwards them to `lead`.
+
+## Fallback: one-shot `codex exec`
+
+For a job that needs no bus, no daemon, and no mid-flight steering:
+
+```bash
+command codex --sandbox workspace-write exec \
+  --json --ignore-user-config --skip-git-repo-check \
+  -C <workdir> -o /tmp/codex-<task>-last.md \
+  "<self-contained prompt>" 2>&1 | tee /tmp/codex-<task>.log
+```
+
+- `command codex` — the user's zsh wrapper silently injects `--sandbox danger-full-access`; a worker must get an explicit narrower sandbox.
+- `--json` — first event is `{"type":"thread.started","thread_id":"..."}`; capture it or the run is not resumable.
+- `--ignore-user-config` — otherwise it loads `~/.codex` config and skills (~450k wasted input tokens) and fires the user's notification hooks.
+- `-o <file>` — read the answer from this file, never by parsing the stream.
+- Never `--ephemeral` if you might resume.
+
+Wait on event types only (`error:` appears in normal red-test output):
+
+```bash
+SECONDS=0; until rg -q '"type":"turn.completed"|"type":"turn.failed"' /tmp/codex-<task>.log 2>/dev/null || [ $SECONDS -ge 600 ]; do sleep 5; done
+rg -q '"type":"turn.completed"|"type":"turn.failed"' /tmp/codex-<task>.log || { echo "TIMEOUT after ${SECONDS}s — turn never terminated"; tail -20 /tmp/codex-<task>.log; exit 1; }
+```
+
+The re-check after the loop is not optional: the loop also exits on the deadline, and a timed-out run still leaves a stale `-o` file on disk. Reading that file without confirming a terminal event reports a half-finished turn as a result. On timeout, stop and report — do not resume blindly.
+
+Resume: `command codex exec resume <thread_id> --json --ignore-user-config --skip-git-repo-check -c sandbox_mode="workspace-write" -o /tmp/codex-<task>-steer.md "<correction>"`. Nothing is inherited from the original invocation — `--ignore-user-config` and `--skip-git-repo-check` must both be repeated, and `--sandbox`/`--cd` are **not** re-applied on resume, so pass sandbox as `-c sandbox_mode=`. Dropping `--ignore-user-config` on resume silently reloads `~/.codex` config and skills mid-thread.
