agent loop detected: repeatedly flagging the same legit newsletter

Not specified by the original author.

TL;DR

When the allowlist stops syncing, the agent judges every message from scratch, and a borderline newsletter that scores just over the phish line gets flagged forever, once per run, with the agent learning nothing. Check the allowlist sync job first, restore it, and add a local verdict cache with a sensible lifetime for stable senders, so one human-approved decision survives even if the sync breaks again.

agent loop detected: repeatedly flagging the same legit newsletter as phish after the allowlist sync failed

Use this when

• The same newsletter issue is flagged as phish in run after run.
• An allowlist entry exists in the source system but the agent keeps flagging the sender.

Not for this skill when

• The newsletter was spoofed in the flagged instance. Check authentication before allowing anything.
• The sender genuinely changed behaviour and now sends phishing-like content. Re-judging is correct.

Steps

1. Verify the flagged messages authenticate as the real newsletter sender. Verify: spoofing is ruled out before any allow decision.
2. Check the allowlist sync job status and last successful run, and compare entry counts with the source. Verify: the sync failure is confirmed and timed.
3. Repair the sync cause and force a full refresh, then confirm the newsletter entry is present in the agent view. Verify: the entry is visible to the agent, not only in the source.
4. Add a verdict cache for allowlisted and repeatedly cleared senders, keyed by authenticated identity, with expiry and audit logging. Verify: a repeat message is cleared by cache with the reason logged.
5. Run the agent over the next newsletter issue. Verify: it passes with the cached decision and no duplicate alert is raised.

Variant phrasings

agent flags same newsletter allowlist sync failed

The allowlist sync variant.

repeated false positive legit sender verdict cache agent

The verdict cache variant.

Compatibility: Agent allowlist stores and sync jobs, Defender tenant allow lists as a source system.

Why it happens

An agent is only as good as its reference data feeds. Allowlist sync is a quiet background job whose failure presents as an intelligence failure in the agent, sending debugging effort to the model instead of the plumbing.

Edge cases / pitfalls

• Key allow decisions on authenticated identity, never on display name or subject similarity.
• Sync jobs need the same monitoring as the agent itself; a stale allowlist is a production incident in slow motion.
• Cache clearances, not just blocks, or the agent relitigates every settled sender daily.

TL;DR

Fix this in the meeting prep briefer by acting on the exact message first: fingerprint every attempt at the task, summarize recent news for a target account, from its inputs plus its last result, stop after two identical fingerprints, and change one thing before retrying, a different source, a narrower query or a human check, recording the repeated action in the run log so the loop is visible. 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: repeating the same meeting prep task to summarize recent news for a target account error loop

Use this when

• The operation in the meeting prep briefer fails with this exact message: Agent loop detected: repeating the same meeting prep task to summarize recent news for a target account error loop.
• The same failure repeats on retry with unchanged inputs.
• A call, review or send is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error 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 meeting prep briefer, and copy the full message plus the account, contact, quote or meeting involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: fingerprint every attempt at the task, summarize recent news for a target account, from its inputs plus its last result, stop after two identical fingerprints, and change one thing before retrying, a different source, a narrower query or a human check, recording the repeated action in the run log so the loop is visible. Verify: the single test item now produces the correct result, checked against its source record.
3. Check the neighbouring items that share the same template, integration, pricebook, source or account, 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 against the source system so a silent partial success is caught before sign off. Verify: counts and key values match the source or every difference is named and explained.
5. Rerun the original operation in the meeting prep briefer on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message 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 error, the fix applied and the evidence of success.

Why it happens

The agent retried summarize recent news for a target account with unchanged inputs after a result it did not recognise as success, so each attempt reproduced the same state and the loop detector tripped.

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.

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.
