Debug a NoInfra Agent That Is Ready but Not Responding

A ready state is useful, but it is not the same thing as a completed job.

When a builder creates a hosted agent, the first reassuring sign is usually that the runtime exists and the setup flow has finished. That state matters. It means you are past the earliest deployment work. But if the agent does not respond to the intended prompt, trigger, or workflow input, the next move should not be to rebuild everything, upgrade immediately, or assume the runtime is broken.

The better move is to split the failure into layers.

A hosted agent can be ready while the work path is still blocked by an empty input, a missing permission, a vague first task, a token budget mismatch, a paused trigger, or an output expectation the agent was never given. Those failures look similar from the outside: "the agent is not responding." They require different fixes.

Use this checklist before you change the agent shape.

Start with the exact response path

Do not debug the whole agent first. Debug the one path that should have produced the first useful response.

Write down four things:

1. What action should start the agent?
2. What input should the agent receive?
3. What output should the agent leave behind?
4. Where should a human confirm that output?

If any of those are unclear, the agent may be ready but not actually addressable. A ready hosted runtime is not a substitute for a first-run contract. "Monitor my inbox" is not as useful as "summarize unread customer emails from the last 24 hours into a short review note and stop if sender context is missing." The second version gives the agent a trigger, a scope, a freshness rule, an output, and a stop condition.

For a first debug pass, make the task smaller than the task you eventually want. Ask for one output from one source over one time window. If that works, widen from evidence. If that does not work, you have a small enough surface to inspect.

Check whether the agent received usable input

The most common quiet failure is not bad reasoning. It is no usable input.

Confirm that the agent received the thing it was supposed to act on. If the job depends on a document, make sure the document link is accessible. If the job depends on a thread, make sure the thread is named or attached. If the job depends on a recurring signal, make sure the signal has produced at least one event since the agent was created.

Then check the shape of the input. A human can infer that "the latest proposal" means a specific file. An agent may need the file, folder, customer name, date range, or exact message. If the workflow depends on data freshness, include the time window directly in the task.

Good debug input looks like this:

• One source
• One owner
• One time window
• One expected output
• One explicit stop condition

Bad debug input asks the agent to infer the entire operating context before it has completed a single hosted run.

Confirm the trigger is real, not implied

Some agents are launched by a direct prompt. Some are meant to react to a recurring signal. Some are waiting for a teammate handoff, a file, a queue item, or a scheduled run. Those are different trigger models.

If the agent is ready but quiet, ask whether anything has actually triggered it.

For a direct prompt, send a small test instruction that does not depend on hidden context. For a recurring workflow, confirm the cadence and the event source. For a queue-based workflow, put exactly one test item in the queue and describe what should happen to it. For a teammate-owned workflow, make sure the handoff says what the agent should do now, not merely what it will do eventually.

This matters because "ready" often means the agent can run, not that it has already been given work.

Keep the debug run inside one budget boundary

When a hosted agent does not respond, builders sometimes jump straight to spend, plan, or token questions. Budget can be the issue, but it should be checked as one layer in the path, not treated as the default explanation.

For a first debug run, reduce the task until the expected output can fit inside a small response. Ask for a short summary, a yes/no classification with reasons, or a list of missing fields. Do not ask the agent to process a broad backlog, inspect every connected source, or produce a polished report while you are still confirming whether the path works.

The goal is not to prove the final workflow in one run. The goal is to prove that the hosted agent can receive the intended input, spend against the right boundary, and leave a reviewable output.

Once that path works, you can decide whether the recurring version needs a larger scope, a different runtime fit, or a different plan. Upgrade decisions should come from evidence, not from the first ambiguous failure.

Create a NoInfra agent with one small debug run: one input, one output, and one owner review before you widen the workflow.

Separate silence from refusal

"Not responding" can mean several things:

• The agent never received the task.
• The task started but had no usable input.
• The task needed a permission or connection that was not available.
• The task exceeded the practical scope for the first run.
• The agent produced output somewhere the owner did not check.
• The agent correctly stopped because the stop condition was met.

Those are not the same failure.

If the agent left a status, receipt, or partial output, treat that as evidence. A refusal or stop can be the correct behavior if the task lacks an owner-approved input, requires unavailable access, or would act beyond the intended scope. The fix is not to make the agent more forceful. The fix is to decide what information or permission should be present before the agent continues.

For production work, a clear stop is better than silent improvisation.

Verify the output location

Sometimes the response path works and the review path does not.

Before changing the agent, check where the output was supposed to appear. Was it a message, a workspace note, a task comment, a document update, or a run record? Did the human owner know where to look? Did the expected output format match the place where it was delivered?

This is especially important for agents that create reviewable work instead of chat replies. A hosted agent may complete a useful step without posting the kind of conversational answer a builder expected. For early runs, make the output location explicit: "Leave the result as a short review note in the workspace" is easier to verify than "handle this."

Do not widen scope until one narrow response works

The temptation after a quiet first run is to add more instructions. That usually makes the problem harder to isolate.

Instead, narrow the workflow until one response is undeniable. Use one source, one action, one output, and one review owner. Confirm the trigger. Confirm the input. Confirm the budget boundary. Confirm the output location. Then run it once.

If the narrow path fails, you have a focused support case or a precise workflow change. If the narrow path works, you have proof that the hosted runtime and response path are usable. From there, widen one dimension at a time: more inputs, a recurring cadence, a teammate handoff, or a stronger output format.

That sequence keeps debugging from becoming redesign.

A simple ready-but-quiet checklist

Before you rebuild or upgrade, answer these questions:

1. What exact event or prompt should trigger the agent?
2. What single input did the agent receive?
3. Does the input include the source, owner, time window, and output format?
4. Is the task small enough for a first debug run?
5. Does the agent have the permission or connection it needs?
6. Where should the output appear?
7. Did the agent stop correctly because a condition was missing?
8. What is the smallest next run that would prove the response path?

That checklist turns "the agent is not responding" into an operator decision. It gives you a way to separate setup, trigger, input, permission, budget, output, and scope without guessing.

A ready agent should become a useful agent through evidence. Start with the smallest response path that can prove the loop.

Create a NoInfra agent and test one hosted response path before you turn the workflow into recurring work.
