Review comments at
@adapters/python/codex/src/nemo_fabric_adapters/codex/adapter.py:
- Around line 1311-1318: Move the API-key presence check in the initialization
flow before constructing AsyncCodex and assigning self._client, so missing
credentials fail without spawning a child process or leaving a client assigned.
Reuse the validated api_key for login_api_key, and update the corresponding test
to assert that no client is created when the key is missing.
Review comments at @examples/harbor/calculator/README.md:
- Around line 191-193: Update the closing note after the Codex section to
replace the inaccurate “Both runs” reference with wording that explicitly names
the OpenClaw, Claude, Pi, and Codex runs; preserve the comparison guidance and
shared task/verifier details.
- Line 154: Update the Harbor --ae credential arguments in the calculator
example to use shell-expanded environment variable values for both
NVIDIA_API_KEY and OPENAI_API_KEY, applying the same quoting style to each.

LGTM, just two minor CodeRabbit nits to address if you had time.
There was a problem hiding this comment.
left one potential security bug comment, and the following readme updates:
Can we update the Codex authentication docs with this behavior? adapters/python/codex/README.md still says NeMo Fabric does not perform login and that an API-key environment variable is not a complete login flow. docs/integrations/harness/codex.mdx likewise tells users to provision the credential store outside Fabric. This PR now performs login_api_key() during runtime startup, so both public surfaces need to describe the new flow and the lifecycle of the secret-bearing CODEX_HOME.

Overview
Harbor 0.23 validates installed agents through typed options and capability declarations. The Fabric runner still targeted Harbor 0.18, so its settings were not represented in current Harbor preflight. The calculator example also cloned a full Hermes Agent checkout, and it had no runnable Pi or Codex path. This PR updates the Fabric runner to Harbor 0.23 and makes the same calculator task runnable with a scripted agent, Pi, and Codex through
FabricAgent.The
nemo-fabric[harbor]extra now requires Harbor 0.23.x; older Harbor releases are outside this integration's supported range. The calculator image no longer clones Hermes Agent. Hermes remains documented in the separate SWE-Bench walkthrough.Details
