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.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=agent loop detected re-verifying already verified domain causing verification failure"

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.

Fix onboarding agent timeout during domain verification DNS lookup

TL;DR

The agent times out on the DNS lookup because it uses a short deadline against slow or cached resolvers. Query the authoritative nameserver with a realistic timeout and retry with backoff. The lookup is slow, not broken.

The error

Onboarding agent timeout
Timed out during domain verification DNS lookup.

Use this skill

Agent? Search Vectle for this error:

curl -s "https://vectle.com/api/v1/search?q=onboarding agent timeout during domain verification dns lookup"

Fix it

Step 1: Query authoritative directly

Point the lookup at the domain's authoritative nameserver.

Expected: You get the true record state fast.

Step 2: Extend the lookup timeout

Raise the DNS timeout to handle slow resolvers.

Expected: Lookups stop timing out spuriously.

Step 3: Retry with backoff

On timeout, retry a few times with growing delays.

Expected: Transient resolver slowness clears.

Step 4: Cache the result for the run

Once verified, reuse the result instead of re-querying.

Expected: No repeated lookups for the same domain.

Step 5: Verify the check passes

Re-run the domain verification step.

Expected: It completes within the new deadline.

When this applies

• Agents time out on domain verification DNS lookups
• Verification steps are flaky on DNS
• You are building domain verification agents

When it doesn't

• The record is wrong (fix the DNS record)
• The domain does not exist (check the domain)
• Lookups fail instantly (check network access)

Compatibility

DNS lookups in verification agents. Standard resolver behavior.

Variant phrasings

agent dns lookup timeout verification

Same failure. Authoritative queries plus realistic timeouts fix it.

domain verification dns slow agent

Slow resolvers are common. Backoff and caching handle them.

onboarding dns check timeout

Timeouts on checks usually mean the check's deadline, not the DNS, is wrong.

Why it happens

Public resolvers can be slow or serve stale cache, and agents with short DNS timeouts give up before getting an answer. The verification logic is fine; the network patience is not.

Edge cases

• Some networks intercept DNS; the agent may need the network's resolver, not a public one
• IPv6-only or IPv4-only networks break lookups that assume both; match the network
• Log the resolver used and the latency so slow lookups are visible

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.

TL;DR

Fix this in Search check agent by acting on the exact symptom first: separate checking from fixing, record the translation issue once as a finding and return to checking the next query, and deduplicate findings by article and locale before any update work is queued. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Agent loop repeating the same translation update while checking search results

Use this when

• Work in Search check agent shows this exact symptom: Agent loop repeating the same translation update while checking search results.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Search check agent, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: separate checking from fixing, record the translation issue once as a finding and return to checking the next query, and deduplicate findings by article and locale before any update work is queued. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Search check agent that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

How to fix - agent stuck loop detected repeating the same translation update while trying to check help center search results for an error query error failure

The how to phrasing for the same problem in Search check agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Search check agent troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

A checker that starts fixing mid check revisits the same article after every query it appears in, converting one translation fault into an endless update loop.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Search check agent at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.
