agent hallucinating flagged post not in source data for merge duplicate commu

Not specified by the original author.

TL;DR

Fix this in duplicate thread merge agent by acting on the exact problem first: build the merge candidate list only from thread ids returned by search results the agent actually fetched, cross check every flagged post it mentions against its thread, and drop any candidate that cannot be traced to a fetched thread before merging. Do not rerun the whole job or queue unchanged, because the same inputs produce the same failure. Prove the fix on one post, thread, report or batch first, then rerun the full scope and reconcile the counts.

Agent hallucinating a flagged post not in the source data during thread merging

Use this when

• The operation in duplicate thread merge agent fails with this exact message or symptom: Agent hallucinating a flagged post not in the source data during thread merging.
• The same failure repeats on retry with unchanged inputs.
• Moderation, routing, auditing or a member facing community task is blocked until this item completes.

Not for this skill when

• The message is an outage notice from the platform. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with a moderation judgment or content quality. That is a policy review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in duplicate thread merge agent, and copy the full message plus the post, thread, report or member involved into the run notes. Verify: the problem is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this problem: build the merge candidate list only from thread ids returned by search results the agent actually fetched, cross check every flagged post it mentions against its thread, and drop any candidate that cannot be traced to a fetched thread before merging. Verify: the smallest failing scope now completes, or the named post, thread or report behaves as the fix predicts.
3. Check the neighbouring posts, threads, reports or members that share the same setting, rule or workflow, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Rerun the original operation in duplicate thread merge agent 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.
5. Compare the result counts or status against the source in duplicate thread merge agent so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
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

An agent working from a task description rather than fetched threads invents plausible duplicate posts, and merging on invented candidates corrupts real threads.

How to fix - agent hallucinating flagged post not in source data for merge duplicate community threads error hallucination failure

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

duplicate thread merge agent troubleshooting for this failure

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

Edge cases

• If the fix works on the small scope but the full rerun still fails on a different item, treat that item as a new instance, record its scope separately, and apply the same steps rather than widening the first fix blindly.
• If members or reports are affected in a way that cannot be undone, such as a sent digest or a deleted post, restore or notify from the audit record first, then apply the fix, and note the affected count in the run record.
• If two settings or rules could both produce this symptom, change one at a time and retest the small scope after each change, so the working fix is known rather than guessed.

Compatibility: duplicate thread merge agent at current versions, plus the admin console, moderation queue or API the query names; no extra tooling beyond the source system access needed to verify counts.

Fix this in flagged post audit agent by acting on the exact problem first: ground every audit verdict in the flagged post text itself, require a quoted span from the post in each verdict, and flag for human review any verdict whose quoted span cannot be found in the post it claims to describe. Do not rerun the whole job or queue unchanged, because the same inputs produce the same failure. Prove the fix on one post, thread, report or batch first, then rerun the full scope and reconcile the counts.

Why it happens

Verdicts written from the report title alone invent content the post never had, and a quoted span requirement makes invention detectable in one check.

Fix this in escalated post routing agent by acting on the exact problem first: route only from the escalation record itself, quoting its thread id and flag reason in the assignment, and reject any routing note that mentions a merge or thread the escalation record does not contain, verifying one assignment against the queue before continuing.

Why it happens

An agent summarising from similar past escalations can invent merge history that never happened, and that invented context sends the post to the wrong owner with the wrong urgency.
