## TL;DR
Fix this in New Relic by acting on the exact message first: draft the NRQL, run it in the query builder to prove it parses and returns data, and create the condition only from a query that ran clean. 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.

```

## Use this when
- The operation in New Relic fails with this exact message: agent hallucinating NRQL query syntax caused baseline condition creation failure error.
- The same failure repeats on retry with unchanged inputs.
- A review, export or check 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 New Relic, and copy the full message plus the item, user or metric 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: draft the NRQL, run it in the query builder to prove it parses and returns data, and create the condition only from a query that ran clean. Verify: the condition saves and its preview shows the expected signal.
3. Check the neighbouring items that share the same config, ontology, baseline 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 New Relic 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, decisions or alerts against the source in New Relic 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 error, the fix applied and the evidence of success.

## Why it happens
NRQL written from memory often invents event names or clause order; the condition builder rejects or silently empties on bad syntax.

## Variant phrasings

### agent hallucinating NRQL query syntax caused baseline condition creation failure error
The verbatim form searchers paste from the terminal or console. Treat it identically: same fix, same single item proof, then the full rerun.

### How to fix: agent hallucinating NRQL query syntax caused baseline condition creation failure error
The how-to phrasing for the same failure in New Relic. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### New Relic 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.

Compatibility: New Relic at current versions, plus the platform API or console the query names; no extra tooling beyond a text editor and the source system access needed to verify counts.
