hermes - 💡(How to fix) Fix bug: oneshot fails closed without final response while chat -q -Q succeeds [1 pull requests]

Summary

Latest main contains the fail-closed fix for empty oneshot responses, but hermes -z still does not produce a final response for the same Copilot/gpt-5.5 path where hermes chat -q -Q succeeds.

This is a follow-up to the closed empty-success issue: the command now exits nonzero, which is good, but the oneshot path still is not usable as a successful no-edit foreground smoke path for this provider/model.

Environment

• Repository: isolated fresh clone of NousResearch/hermes-agent
• HEAD: 1044d9f25d63b48c51fe40af0a4cfeea3b6de516
• Contains fix commit: 9fbde54b5176b6a2fef198b6d870704a3fd994d6
• uv run --extra dev pytest tests/hermes_cli/test_tui_resume_flow.py -q: 45 passed
• Campaign context: briancl2/build-meta-analysis#164 Hermes sidecar reconciliation proof

Reproduce

timeout 180 uv run hermes --provider copilot -m gpt-5.5 -z "Reply with exactly: HERMES_Z_OK"

Also tried equivalent argument orderings:

timeout 180 uv run hermes -z "Reply with exactly: HERMES_Z_OK" --provider copilot -m gpt-5.5
timeout 180 uv run hermes -m gpt-5.5 --provider copilot -z "Reply with exactly: HERMES_Z_OK"

Observed

All three -z invocations:

• exit status: 1
• stdout: empty
• stderr: hermes -z: no final response was produced; treating the run as failed.

Control That Succeeds

timeout 240 uv run hermes chat --provider copilot -m gpt-5.5 -q "Reply with exactly: HERMES_CHAT_OK" -Q

Observed:

• exit status: 0
• stdout: HERMES_CHAT_OK
• BMA foreground stdout validator: PASS
• stderr only included a session_id line

Expected

If the provider/model can produce a final response through chat -q -Q, oneshot should either:

1. produce the same final response text to stdout and exit 0; or
2. surface enough diagnostic context to explain why oneshot cannot use that path.

Boundaries

This report asks for a foreground CLI contract repair only. It does not request retries, queues, schedulers, daemons, controllers, background jobs, or broader autonomy behavior.
