I'd like to work on this issue.

I'll investigate the Agentic Triage workflow configuration, identify the root cause of the model/endpoint incompatibility, and submit a fix if the issue can be reproduced and validated.

Please assign this issue to me if available.

[VenkateshDevarakonda0706]

I've investigated the failure and identified a model-routing issue in the Agentic Triage workflow.

The workflow currently uses engine.model: small, which can be steered to an incompatible GPT-5 mini variant that is not supported by the /chat/completions endpoint.

I have prepared a fix that switches the workflow to gpt-5-nano and regenerated the lock file using the repository's pinned gh-aw v0.77.5 version to keep the diff minimal.

I'll open a PR shortly.
