No Output
How to debug a Hermes Agent that appears online but produces no output in response to user prompts.
No-output failures are frustrating because they hide several possible causes behind the same user-visible symptom: silence.
What the symptom usually means
The deployment seems alive, but prompts receive no reply, partial logs, or behavior that suggests the message never made it all the way through the stack.
Most likely causes
Possible causes include channel delivery failure, provider errors, invalid credentials, prompt-level blocking logic, or a runtime state that is alive enough to look healthy but not actually process the request.
Recommended fix order
Check channel delivery first, then provider validation, then logs, and only after that inspect prompt logic or workflow rules that may suppress visible output.
Work from identity and connectivity first, then provider settings, then higher-level prompt or runtime assumptions. That sequence avoids wasting time on downstream symptoms.
Get back to a working Hermes deployment faster
Hermes Host reduces the number of moving parts you have to debug at once, which makes channel, provider, and runtime issues much easier to isolate.
FAQ
Why is no output harder than an explicit error?
Because silence can happen at multiple layers, so the symptom alone does not tell you where the request died.
What is the fastest narrowing step?
Send the smallest possible test prompt and verify each layer in order: channel, runtime, provider, then prompt logic.
