If Codex fails, the call fails with a clear log message; it never falls back to Claude (or to an API key). A Codex-only machine doesn't need Claude installed. +- **Your Codex setup is left alone.** Each call runs throwaway `codex` processes in a private temporary home and empty workspace, so your `~/.codex/config.toml`, MCP servers, plugins, hooks, skills, `AGENTS.md` and memories are never loaded, and Harvey's model choice never changes your own Codex default. +- **No tools, verified before every prompt.** Prompts contain untrusted text (prospect replies, scraped pages), so the model must have nothing to act with. Harvey disables every tool-providing Codex feature, web search, sub-agents, hooks, skills and project instructions, starts the thread with no execution environment, and then checks Codex's own reports (effective config, account type, thread settings, MCP status, hooks) before sending anything. Anything it can't confirm stops the call. During the turn, any attempted tool call, approval request or non-text item kills the runtime. A read-only sandbox is also set, as extra protection only. +- **Your login only goes to OpenAI.** Before your login is put into the runtime at all, Harvey starts Codex without it and checks that requests would go to the built-in OpenAI provider and the default ChatGPT endpoint. Any custom provider, overridden built-in provider, base URL, telemetry exporter or other endpoint in any Codex config layer (for example `/etc/codex/config.toml` or a managed config) stops the call there. +- **Login handling.** Harvey supports Codex's file credential storage (`~/.codex/auth.json`, or `$CODEX_HOME/auth.json`, mode `600`): the default unless you've configured an OS keyring. Keyring storage isn't supported. On every call Harvey reads that file (read-only, never writing or moving it) and gives the runtime a private copy *without the refresh token*, deleted after the call. Codex therefore can't change or renew your real login. When the login has expired, or is due for Codex's routine renewal (after about 8 days), Codex calls stop with "Your Codex login has expired or is due for renewal". Use Codex once yourself (it renews the login automatically) or run `codex login`, and Harvey picks up the renewed login on its next call. Harvey never renews it for you. +- **Models.** Use `model: gpt-5.5`. It's the model Harvey has verified as text-only with Codex 0.159.3 (no code mode, no extra tools), and it works on ChatGPT plans even though Codex's live catalog hides it from the model picker. Codex's newer "code mode" models (`gpt-6-*`, `gpt-5.6-*`) always carry built-in code-execution tools that no setting removes, so Harvey refuses them. If you leave `model` blank, Harvey only auto-selects a model the catalog *lists* and that has no code mode or extra tools. On current ChatGPT accounts no listed model qualifies, so a blank `model` fails with an error naming the hidden models you can set explicitly, plus each model's reason. If you set `model`, Harvey uses exactly that model or fails; it never substitutes another. Naming a code-mode model gives an error listing the models that work. +- **Quota.** The budget gate and dashboard read your ChatGPT plan's real rate-limit windows from Codex, for the limit bucket that applies to your model, and compare them to `usage.max_daily_claude_percent`. If Codex reports that usage is blocked, or a call fails on the plan's usage limit, Harvey treats the plan as full (even when no window is reported) and stops Codex calls for an hour. If the limits can't be read, the dashboard and `harvey usage` say "Quota unavailable" and the budget falls back to Harvey's own daily call count. Usage is recorded per provider; Codex calls are logged with tokens but no dollar cost, because the plan isn't billed per token. +- **When Codex can't be used, Harvey pauses rather than guessing.** Before each heartbeat, Harvey checks everything a call needs except the prompt itself: the Codex CLI version, the isolation, your login (expired or due for renewal), your ChatGPT account, and that your configured model can run with no tools. No prompt is sent, so nothing is used from your plan beyond a quick account check. If something is wrong, the whole cycle is skipped: no reply is read or marked handled, nothing is drafted or sent. The log line, `harvey status`, and the dashboard's Actions card say "Codex paused" and why. If Codex stops working part-way through a cycle (for example the plan hits its usage limit), the reply being handled is left exactly as it was for a clean retry, not escalated, half-recorded or lost, and that cycle sends nothing. Fix the cause (usually `codex login`), and Harvey resumes on its next heartbeat: a renewed login or reinstalled CLI is noticed immediately, a usage-limit pause ends after an hour, and other fixes are picked up within 30 minutes. `harvey status --check` runs the same check on demand and exits non-zero if it fails. Brief failures (a crash or timeout) just skip one cycle. Harvey never falls back to Claude or an API key. +- **Requirements.** **macOS or Linux**, Codex CLI **0.159.3** exactly, and Node.js for its npm package. **Windows isn't supported for Codex:** Harvey refuses it there before reading your login; use the Claude provider on Windows. Harvey checks the Codex version before every call and refuses any other version, including newer ones, because a different Codex can add tools Harvey's lockdown doesn't know about. Support for a new version comes with a Harvey update. Live use with a real ChatGPT account has been verified on macOS; Linux uses the same code and is covered by Harvey's tests, but hasn't yet been run against a real account. The Docker image ships the Claude CLI only, so Codex isn't supported in Docker. To re-verify the lockdown offline against your installed CLI, with no credentials or network: `HARVEY_CODEX_CLI_TESTS=1 pytest tests/test_codex_cli_surface.py`. +- **Overhead.** Each call checks the CLI version, starts Codex once without your login to verify its configuration, reads the model catalog, then starts it again to run the prompt; each heartbeat's check does the same without the prompt. That adds a few seconds per call, and one Brain's Codex calls run one at a time. + --- ## Legal and deliverability @@ -455,6 +491,8 @@ Harvey automates outreach, but **you are the sender.** Cold email is legal in mo **Claude headless mode fails** — `claude login`, and confirm the subscription is active.

Common Issues

Make sure you've run claude login in your terminal and have an active Claude Max subscription. Harvey uses your existing subscription, not a separate API key.
+
+ Codex calls fail +
With brain.provider: codex, set brain.model: gpt-5.5 (the verified text-only model; a blank model fails on current ChatGPT accounts and code-mode models are refused), run codex login and choose "Sign in with ChatGPT" (API-key logins are refused). Harvey never renews your Codex login: if the log says it has expired or is due for renewal, use Codex once or run codex login. Harvey needs Codex CLI 0.159.3 on macOS or Linux (Codex isn't supported on Windows; use Claude there) and refuses other versions. While Codex can't be used, Harvey pauses (the Actions card shows "Codex paused" and why), leaves replies and queued emails untouched, and resumes once it's fixed; harvey status --check checks on demand. If the log says isolation could not be verified, a Codex config layer is forcing a tool, hook, MCP server or custom endpoint back on — Harvey refuses to send prompts until it is removed. Harvey never falls back to Claude on its own.
