## TL;DR
Fix this in Salesforce linking agent by acting on the exact problem first: break the loop by separating theme tagging from account linking into two steps, link on contact and account identifiers only, and add a done marker per response so a tagging repeat cannot block linking progress. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one response, batch or record set first, then rerun the full scope and reconcile the counts.

agent stuck loop - repeating the same verbatim theme tag while linking an NPS response
```

## Use this when
- The operation in Salesforce linking agent fails with this exact problem or symptom: agent stuck loop - repeating the same verbatim theme tag while linking an NPS response.
- The same failure repeats on retry with unchanged inputs.
- NPS follow-up, routing or reporting 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 its output quality. That is a quality review, not this failure.

## Steps
1. Reproduce the failure with the smallest scope that still shows it in Salesforce linking agent, and copy the full problem plus the response, contact or job 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: break the loop by separating theme tagging from account linking into two steps, link on contact and account identifiers only, and add a done marker per response so a tagging repeat cannot block linking progress. Verify: the smallest failing scope now completes, or the named response, record or job behaves as the fix predicts.
3. Check the neighbouring responses, records or jobs that share the same config, segment 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. Rerun the original operation in Salesforce linking agent 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 counts or status against the source in Salesforce linking 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
The agent coupled an unrelated tagging repeat to the linking step, so the loop in tagging starved the link write that never needed the tag at all.

## Variant phrasings

### agent stuck loop - repeating the same verbatim theme tag while linking an NPS response
The verbatim form searchers paste from the console or report. Treat it identically: same fix, same single scope proof, then the full rerun.

### How to fix - agent stuck loop detected repeating the same verbatim theme tag while trying to link an NPS response to a Salesforce account error failure
The how-to phrasing for the same failure in Salesforce linking agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### Salesforce linking agent troubleshooting for this failure
The symptom-first phrasing used when the console hides the full message. Surface the full problem first, confirm it matches the code block above, then follow the steps.

Compatibility: Salesforce linking agent at current versions, plus the platform API or console the query names; no extra tooling beyond the source system access needed to verify counts.

Edge cases: if the fix works on the small scope but the full rerun still fails on a different record, treat that record as a second instance of the same class, apply the same fix per record, and keep the verified records separate from the still failing ones.
