Claude Code, Codex & Copilot Subscriptions

Last updated 2026-11-14

How to run Agenvoy on an existing subscription instead of an API key, after the quickstart works.
Subscriptions are the recommended way to run Agenvoy, and the quickstart already starts on GitHub Copilot. These four are also the first choice for a second, fall-back model: the cost is already fixed monthly, so an agent that takes a few extra turns doesn't move the bill.

Provider	Billed against	Where it lives in the menu
Codex	Your ChatGPT / Codex subscription	OAuth tab → `OpenAI Codex`
Grok (xAI)	Your xAI subscription	OAuth tab → `Grok (xAI)`
GitHub Copilot	Your GitHub Copilot subscription	OAuth tab → `GitHub Copilot`
Claude Code	Your Claude subscription, through the local `claude` CLI	OAuth tab → `Claude Code` (shown only when the `claude` binary is found)

None of them takes an API key. Codex and Grok open a browser authorization page; Copilot uses a device-code flow. Either way the token lands in the OS keychain like any other credential. Claude Code has no login of its own: it runs the claude CLI you have already installed and signed in, so claude has to be on the daemon's PATH.

Add Codex

Step	What you do
1	`/model` → add
2	The picker opens on the OAuth tab (←/→ switches tabs)
3	Choose `OpenAI Codex` — not `OpenAI` on the API Key tab, which is pay per token. Before v1.0.22 this was OpenAI → OpenAI method → `Codex subscription`
4	The OAuth popup opens and your browser goes to the authorization page once it is ready (Enter re-opens it). Sign in and approve — the flow has a 15-minute window
5	Back in the TUI, pick a model from the list your subscription exposes

Add Grok (xAI)

Step	What you do
1	`/model` → add
2	Stay on the OAuth tab
3	Choose `Grok (xAI)`
4	Same browser OAuth flow as Codex
5	Pick a model

Add GitHub Copilot

Step	What you do
1	`/model` → add
2	Stay on the OAuth tab
3	Choose `GitHub Copilot`
4	The popup shows a verification URL and a user code; press Enter to open that page in the browser, enter the code and approve. Same 15-minute window
5	Pick a model from the ones your Copilot plan offers

Add Claude Code

Step	What you do
1	Install the `claude` CLI and sign in to it with your Claude account; it must be on `PATH`
2	Nothing to enable: the daemon picks up Claude Code as soon as `claude` is on its `PATH`. If you installed `claude` after the daemon started, run `agen stop` and start `agen` again so the daemon sees the new `PATH`
3	`/model` → add, stay on the OAuth tab and choose `Claude Code` — the row is hidden until the binary is found
4	No browser step. Pick a model from the list the `claude` CLI reports for your subscription

Details such as caching and session reuse are on Claude Code Provider.

Already authenticated once with Codex, Grok or Copilot? The flow asks <Provider> token exists re-login? first. No keep existing reuses the stored token and jumps straight to the model list — pick Yes re-authenticate only when switching accounts.

With more than one model registered, Shift+W / Shift+S cycles the session model from the TUI (auto lets the dispatcher pick), and /model dispatch / /model summary set the dispatcher and summary models explicitly.
