OpenAI's OAuth token endpoint returns errors in a nested shape —
{"error": {"code": "refresh_token_reused", "message": "..."}} —
not the OAuth spec's flat {"error": "...", "error_description": "..."}.
The existing parser only handled the flat shape, so:
- `err.get("error")` returned a dict, the `isinstance(str)` guard
rejected it, and `code` stayed `"codex_refresh_failed"`.
- The dedicated `refresh_token_reused` branch (with its actionable
"re-run codex + hermes auth" message and `relogin_required=True`)
never fired.
- Users saw the generic "Codex token refresh failed with status 401"
when another Codex client (CLI, VS Code extension) had consumed
their single-use refresh token — giving no hint that re-auth was
required.
Parse both shapes, mapping OpenAI's nested `code`/`type` onto the
existing `code` variable so downstream branches (`refresh_token_reused`,
`invalid_grant`, etc.) fire correctly.
Add regression tests covering:
- nested `refresh_token_reused` → actionable message + relogin_required
- nested generic code → code + message surfaced
- flat OAuth-spec `invalid_grant` still handled (back-compat)
- unparseable body → generic fallback message, relogin_required=False

Codex OAuth refresh tokens are single-use and rotate on every refresh.
Sharing them with the Codex CLI / VS Code via ~/.codex/auth.json made
concurrent use of both tools a race: whoever refreshed last invalidated
the other side's refresh_token. On top of that, the silent auto-import
path picked up placeholder / aborted-auth data from ~/.codex/auth.json
(e.g. literal {"access_token":"access-new","refresh_token":"refresh-new"})
and seeded it into the Hermes pool as an entry the selector could
eventually pick.
Hermes now owns its own Codex auth state end-to-end:
Removed
- agent/credential_pool.py: _sync_codex_entry_from_cli() method,
its pre-refresh + retry + _available_entries call sites, and the
post-refresh write-back to ~/.codex/auth.json.
- agent/credential_pool.py: auto-import from ~/.codex/auth.json in
_seed_from_singletons() — users now run `hermes auth openai-codex`
explicitly.
- hermes_cli/auth.py: silent runtime migration in
resolve_codex_runtime_credentials() — now surfaces
`codex_auth_missing` directly (message already points to `hermes auth`).
- hermes_cli/auth.py: post-refresh write-back in
_refresh_codex_auth_tokens().
- hermes_cli/auth.py: dead helper _write_codex_cli_tokens() and its 4
tests in test_auth_codex_provider.py.
Kept
- hermes_cli/auth.py: _import_codex_cli_tokens() — still used by the
interactive `hermes auth openai-codex` setup flow for a user-gated
one-time import (with "a separate login is recommended" messaging).
User-visible impact
- On existing installs with Hermes auth already present: no change.
- On a fresh install where the user has only logged in via Codex CLI:
`hermes chat --provider openai-codex` now fails with "No Codex
credentials stored. Run `hermes auth` to authenticate." The
interactive setup flow then detects ~/.codex/auth.json and offers a
one-time import.
- On an install where Codex CLI later refreshes its token: Hermes is
unaffected (we no longer read from that file at runtime).
Tests
- tests/hermes_cli/test_auth_codex_provider.py: 15/15 pass.
- tests/hermes_cli/test_auth_commands.py: 20/20 pass.
- tests/agent/test_credential_pool.py: 31/31 pass.
- Live E2E on openai-codex/gpt-5.4: 1 API call, 1.7s latency,
3 log lines, no refresh events, no auth drama.
The related 14:52 refresh-loop bug (hundreds of rotations/minute on a
single entry) is a separate issue — that requires a refresh-attempt
cap on the auth-recovery path in run_agent.py, which remains open.
OpenAI OAuth refresh tokens are single-use and rotate on every refresh.
When Hermes refreshes a Codex token, it consumed the old refresh_token
but never wrote the new pair back to ~/.codex/auth.json. This caused
Codex CLI and VS Code to fail with 'refresh_token_reused' on their
next refresh attempt.
This mirrors the existing Anthropic write-back pattern where refreshed
tokens are written to ~/.claude/.credentials.json via
_write_claude_code_credentials().
Changes:
- Add _write_codex_cli_tokens() in hermes_cli/auth.py (parallel to
_write_claude_code_credentials in anthropic_adapter.py)
- Call it from _refresh_codex_auth_tokens() (non-pool refresh path)
- Call it from credential_pool._refresh_entry() (pool happy path + retry)
- Add tests for the new write-back behavior
- Update existing test docstring to clarify _save_codex_tokens vs
_write_codex_cli_tokens separation
Fixes refresh token conflict reported by @ec12edfae2cb221
* refactor: re-architect tests to mirror the codebase
* Update tests.yml
* fix: add missing tool_error imports after registry refactor
* fix(tests): replace patch.dict with monkeypatch to prevent env var leaks under xdist
patch.dict(os.environ) can leak TERMINAL_ENV across xdist workers,
causing test_code_execution tests to hit the Modal remote path.
* fix(tests): fix update_check and telegram xdist failures
- test_update_check: replace patch("hermes_cli.banner.os.getenv") with
monkeypatch.setenv("HERMES_HOME") — banner.py no longer imports os
directly, it uses get_hermes_home() from hermes_constants.
- test_telegram_conflict/approval_buttons: provide real exception classes
for telegram.error mock (NetworkError, TimedOut, BadRequest) so the
except clause in connect() doesn't fail with "catching classes that do
not inherit from BaseException" when xdist pollutes sys.modules.
* fix(tests): accept unavailable_models kwarg in _prompt_model_selection mock
