agent loop detected: repeatedly renewing the same already-valid cert

Fix agent loop re-verifying an already verified domain

TL;DR

The agent re-verifies because it never persists the verified state and the check runs on a schedule. Record the verification result with a timestamp, skip verified domains, and only re-check when something changes. Verification is a state, not a ritual.

The error

Agent loop detected
Re-verifying already verified domain, causing verification failure on rate limits.

Fix it

Step 1: Stop the verification loop

Pause the scheduled verification job.

Expected: No more redundant checks.

Step 2: Record the verified state

Store the domain, verification result, and timestamp durably.

Expected: The agent knows what is already verified.

Step 3: Skip verified domains

Before verifying, check the stored state and skip when still valid.

Expected: Verified domains are not re-checked pointlessly.

Step 4: Re-check only on change

Trigger re-verification on DNS changes or expiry, not on a timer.

Expected: Checks happen when they matter.

Step 5: Resume and verify

Resume the job and watch it skip verified domains.

Expected: No redundant verifications and no rate-limit failures.

When this applies

• Agents re-verify already verified domains
• Verification jobs hit rate limits
• You are building domain verification agents

When it doesn't

• The domain never verifies (fix the DNS records)
• Verification state is lost (fix the state store)
• The provider requires periodic re-verification (honor their schedule)

Compatibility

Domain verification flows generally.

Variant phrasings

agent re-verifying verified domain

Same loop. Persisted state plus skip logic fixes it.

domain verification loop agent

Loops come from stateless schedules. Add state.

verification failure rate limit agent

Rate-limit failures from redundant checks are self-inflicted. Stop the redundancy.

Why it happens

Verification jobs that run on a cron with no memory re-check everything every time. Providers rate-limit verification attempts, so the redundant checks eventually fail and look like a real problem. The job needs to remember what it already proved.

Edge cases

• Verification can legitimately expire; store the expiry and re-check only then
• DNS changes should invalidate the cached verification
• Log skip decisions so audits can see why a domain was not re-checked

If it still fails

• Reproduce with a minimal run: one user, one file, one step.
• Read the agent's full trace, not just the final error; the failure is usually upstream.
• Check the underlying API or tool directly, outside the agent, to separate agent bugs from service bugs.
• Reduce concurrency to one and see if the failure persists; races hide as flakes.
• If the run is business-critical, add a human checkpoint before the destructive steps.

Prevention

• Checkpoint long runs so any failure resumes instead of restarting.
• Cap and back off every retry loop; unbounded retries are outages waiting to happen.
• Validate inputs at each pipeline stage; fail fast with clear errors.
• Log enough context per step that a timeout is diagnosable without rerunning.
• Give destructive steps a human checkpoint or a dry-run mode.

TL;DR

Fix this by acting on the exact problem first: change the completion check for the step the agent repeats while trying to collect an expiring insurance certificate from a vendor so it recognises the result it already retrieved as done, for example by matching on the vendor record identifier rather than a page state that never changes, and rerun with that check in place. Do not rerun the same operation unchanged, because the same inputs produce the same failure. Prove the fix on one agent run for one vendor first, then rerun the full scope and reconcile the results.

agent stuck loop detected repeating the same step while trying to collect an expiring insurance certificate from a vendor error failure

Use this when

• The operation in the agent workflow fails with this exact problem: agent stuck loop detected repeating the same step while trying to collect an expiring insurance certificate from a vendor error failure.
• The same failure repeats on retry with unchanged inputs.
• A vendor risk review, questionnaire, screening or vendor record update is blocked until this is resolved.

Not for this skill when

• The notice is a platform outage from the vendor. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with a risk judgement or a tier decision. That is a risk owner decision, not this failure.

Steps

1. Reproduce the failure on one named agent run for one vendor in the agent workflow and record the full problem text plus the vendor, record or report involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: change the completion check for the step the agent repeats while trying to collect an expiring insurance certificate from a vendor so it recognises the result it already retrieved as done, for example by matching on the vendor record identifier rather than a page state that never changes, and rerun with that check in place. Verify: the single failing agent run for one vendor now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring vendor records, questionnaires or reports that share the same workflow, template or schedule, because this class of failure rarely affects only one vendor. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in the agent workflow on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
5. Compare the result against the source of truth, the vendor supplied document, the questionnaire response or the risk record, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the vendor record or review log so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

How to fix - agent stuck loop detected repeating the same step while trying to collect an expiring insurance certificate from a vendor error failure

The how to phrasing for the same failure in the agent workflow. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

The agent workflow troubleshooting for this failure

The symptom first phrasing used when the console hides the full problem. Surface the full problem first, confirm it matches the text block above, then follow the steps.

Why it happens

An agent loops when its completion check never recognises the result it already produced, often because it waits on a page state or wording that does not change, so it repeats a successful step until the run is stopped.

Edge cases

• The vendor record, questionnaire version or portal page changed after the failing run started. Refresh the current state and reapply the fix against the current values, not the values from the failed run.
• The single scope proof passes but the full rerun still fails on other vendors. Treat each remaining failure as its own scope, because a shared workflow, template or schedule can hide more than one cause.
• The source systems disagree on the correct value. The vendor supplied document governs what the vendor attested, the risk tool record governs the stored score or status, and the procurement record governs vendor identity and lifecycle status; record which source won and why.

Compatibility: The agent workflow at current versions, plus the vendor risk, procurement or source system the query names; no extra tooling beyond access to the source records needed to verify results.

TL;DR

Fix this in the agent loop guard for compliance evidence by doing this first: add an attempt cap and a seen-state check to the compliance evidence job so the same input cannot be processed twice in one run, back off between retries, and surface the blocked item for a human decision after the cap instead of looping. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

agent loop detected with repeating the same compliance evidence validation

Use this when

• The operation fails with this exact problem: agent loop detected with repeating the same compliance evidence validation.
• The same failure repeats on retry with unchanged inputs.
• An audit, review, or request is blocked until this item completes.

Not for this skill when

• The message is a platform outage notice or a general sign-in failure. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the agent loop guard for compliance evidence, and copy the full message plus the item, account, or request involved into the run notes. Verify: the problem is reproduced on demand with a named item, not only seen in an old log.
2. Apply the specific fix for this problem: add an attempt cap and a seen-state check to the compliance evidence job so the same input cannot be processed twice in one run, back off between retries, and surface the blocked item for a human decision after the cap instead of looping. Verify: the single test item now completes or shows the expected state on a direct read-back from the source.
3. Check the neighbouring items that share the same connection, mapping, owner, or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions, or statuses against the source system so a silent partial success is caught before sign-off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
6. Record the fix, the triggering input, and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied, and the evidence of success.

Why it happens

Nothing records that the step already ran or already failed, so the scheduler hands the agent the identical input again and the run burns its budget on repetition instead of progress.
