What

Two changes to the developer profile that remote agents load, so a developer enrolls only their own accounts:

1. Depot comes from the shared vault, not the profile. The profile no longer has a depot section, and the enroll form no longer asks for it.

   • At Sandbox start, the bootstrap reads the Depot organization and token named by the via profile's depot service, using the profile's 1Password service account token:

     [services.depot]
     provider = "onepassword"
     secrets.organization = "op://Buzz Agents Dev/Depot/organization"
     secrets.token = "op://Buzz Agents Dev/Depot/credential"

   • It writes the same depot-token and depot.json files as before, so buzz-agent-cache is unchanged.

   • Without the service, or if the vault read fails, the session starts without the remote cache and logs Depot cache unavailable; no value is printed.

2. Codex can run on a ChatGPT Business or Enterprise seat, in parallel with a Claude subscription.
   • New model credential codex_access_token, a Codex access token (at-…), exported as CODEX_ACCESS_TOKEN.
   • It has no refresh token, so every Sandbox and worker can use it at once. A shared ChatGPT login cache can't do that: its refresh token rotates.
   • With claude_oauth_token (from claude setup-token), one profile now carries both subscriptions.
3. An OpenRouter key for the Buzz agent runtime.
   • New model credential openrouter_api_key, exported as OPENROUTER_API_KEY.
   • The bootstrap also sets BUZZ_AGENT_PROVIDER=openrouter unless the agent sets its own, so the buzz-agent runtime can run any OpenRouter model, for example qwen/qwen3-coder.
   • The Buzz agent reads its model at startup and refuses to start without one. The Remote workspace launch therefore now sends the agent's model as BUZZ_AGENT_MODEL for that runtime, as it already sends ANTHROPIC_MODEL for Claude.

Rules

The image (profile.py), the manager (profile.rs) and the GPUI form (enroll.rs) apply the same rules:

• The profile fields are version, developer, owner_pubkey, git, github, via and models. A profile with depot is refused with "Profile fields are incomplete or unsupported". No profile has been enrolled yet (the staging profile secret has no versions), so nothing stored breaks.
• models accepts openai_api_key, codex_access_token, anthropic_api_key, claude_oauth_token and openrouter_api_key. API keys still work as before.
• openai_api_key and codex_access_token can't be combined, because Codex reads CODEX_ACCESS_TOKEN before its saved API-key login (codex-rs/login/src/auth/manager.rs at rust-v0.159.3). The message is "Choose either an OpenAI API key or a Codex access token".
• codex_access_token must start with at- ("Use a Codex access token (at-...)"). This catches an API key pasted into the wrong field. Codex treats anything else as an agent-identity JWT.
• The bootstrap refuses an inherited CODEX_ACCESS_TOKEN or OPENROUTER_API_KEY, like the other model variables.
• The Codex device-login setup gate refuses a Codex access token and an OpenRouter key, as it refuses API keys.
• The token is only an environment variable; it is never written to workspace files.

GPUI form

• The Depot organization and token fields are removed.
• A Codex access token field is added.
• The model fields are now two rows: subscriptions first (Codex access token, Claude subscription token), then API keys (OpenAI, Anthropic, OpenRouter).

Tests

• buzz-sandbox-reaper: all 89 tests pass. They cover the new profile rules, the refused legacy depot section, and the manager fixtures.
• GPUI remote_workspace tests (16 pass): the Buzz agent launch sends BUZZ_AGENT_MODEL; both subscriptions together, OpenAI key plus Codex token refused, a non-at- token refused, and no Depot fields.
• test-profile.py (runs in the image workflow):
  • a fake op serves the Depot values, and every valid mode asserts depot-token was loaded from it;
  • new modes: subscriptions (Codex token, Claude token and OpenRouter key together), no-depot (vault read fails and the session still starts), and inherited-codex and inherited-openrouter (refused);
  • enrollment refuses a mixed OpenAI and Codex profile, and a token without at-;
  • the workspace scan checks that the Codex token is never written to a file.
• profile.py edge cases, checked locally: no depot service, op failure, non-op:// references, and scalar services or secrets all fall back to no cache.

Not in this change

• No checkpoint secret-scan rule for Codex access tokens yet. I'll add one once we have seen a real token's character set; a guessed regex could miss tokens or block checkpoint saves on ordinary text. The token is never written to the workspace by the image.
• Access tokens expire within the workspace's limit (for example 90 days), so the developer re-enrolls before then. A host-managed refresh, like Zed and the local Buzz app do, needs a supported way to refresh a subscription login on behalf of a swarm, which OpenAI doesn't document for Codex today. That is a follow-up.

Deploy

After merge, voltage-agent-images.yml publishes new agent and reaper images. Then:

• pin both images in cd: the gate, the reaper, and the manager's sandboxProviderConfig;
• pin the agent image in voltage-terraform staging-agent (agent_image);
• rebuild GPUI from the new commit.

📝 Walkthrough

Enrollment and profile validation now support Codex access tokens and no longer use top-level Depot credentials. The bootstrap retrieves Depot credentials from the via profile’s vault service and writes them when available.

Changes: Profile credentials

Codex enrollment and profile validation apps/buzz-gpui/crates/app/src/agent_plugins/remote_workspace/*, crates/buzz-sandbox-reaper/src/*, voltage/images/buzz-agent/profile.py, voltage/images/buzz-agent/profile.example.json, voltage/images/buzz-agent/README.md, voltage/images/buzz-agent/test-profile.py, voltage/images/buzz-agent/test-restore.py	Enrollment forms and profile validators accept Codex access tokens, require the at- prefix, and reject combining them with OpenAI API keys. The enrollment and example profiles no longer include Depot fields. Tests and documentation cover the changed profile shape.
Vault-backed Depot bootstrap voltage/images/buzz-agent/profile.py, voltage/images/buzz-agent/test-profile.py, voltage/images/buzz-agent/README.md	Bootstrap reads Depot credential references from the via profile’s depot service. It writes Depot credential files when lookup succeeds and continues without the remote cache when credentials are unavailable. Bootstrap also exports supplied Codex tokens as CODEX_ACCESS_TOKEN.

Merge Risk: 🟠 High · up to fc593

Previously enrolled Sandboxes may fail to start after deployment, and an unreadable shared Depot credential can also prevent startup instead of merely disabling the cache. Resolve both startup paths before merging.

- Around line 148-149: Update the early return guarded by the `services` and
`DEPOT_SERVICE` check to emit the documented “Depot cache unavailable” warning
when the Depot entry is missing, then preserve the existing `None` return.
- Line 16: Update FIELDS so validate() accepts profiles containing the legacy
top-level depot field, allowing depot(profile) to handle it without rejecting
the profile first.
- Around line 157-167: Update the exception handler in depot() to catch
subprocess.CalledProcessError alongside the existing fallback exceptions, so
failed op reads return None and bootstrap continues without the remote cache.
