[aw] PR Sous Chef hit HTTP 400 bad request

[github-actions]

Workflow Failure

Workflow: PR Sous Chef
Branch: main
Run: https://github.com/github/gh-aw/actions/runs/28496369539

Warning

HTTP 400 Bad Request from agentic engine: The agent failed after the engine returned Response status code does not indicate success: 400 (Bad Request).

This is usually a request validation failure rather than a timeout or quota issue.

How to debug this

1. Inspect the run's agent-stdio.log and safeoutputs.jsonl artifacts around the first HTTP 400.
2. Check for malformed request data, invalid tool-call payloads, or stale conversation state being replayed.
3. If the failure happened on a resumed session, rerun fresh once to confirm whether persisted state is corrupt.

Warning

Engine Failure: The copilot engine terminated unexpectedly.

Recurrence Context

This failure is a recurrence after #42444 was closed (Jun 30 22:50). The previous fix targeted gpt-5.5 routing via /chat/completions → /responses, but failures resumed on Jul 1:

• ✅ 1 success at 02:28 Jul 1
• ❌ Failure at 03:56 Jul 1
• ❌ Failure at 05:44 Jul 1

The single success at 02:28 may have been a lucky race condition or test run. The root cause (model routing for gpt-5.5) appears unresolved.
