agent hallucinating root cause from correlated but unrelated deploy error investigation failed

Not specified by the original author.

TL;DR

Fix this in the anomaly investigation by acting on the exact message first: name a deploy as the cause only when the metric move starts inside its window and the affected service matches, otherwise report the correlation as unproven and list what evidence would settle it. 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 hallucinating root cause from correlated but unrelated deploy error investigation failed

Use this when

• The operation in the anomaly investigation fails with this exact message: agent hallucinating root cause from correlated but unrelated deploy error investigation failed.
• 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 the anomaly investigation, 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: name a deploy as the cause only when the metric move starts inside its window and the affected service matches, otherwise report the correlation as unproven and list what evidence would settle it. Verify: sampled investigations cite metric evidence for every claimed cause.
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 the anomaly investigation 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 the anomaly investigation 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

A nearby deploy is the easiest story to tell; without a window and service match the explanation is a guess dressed as a finding.

TL;DR

Fix this in the anomaly detector by acting on the exact message first: constrain the agent to ids and values returned by the source API in this run, reject any label, reviewer or cause not in that returned set, and log the rejection. 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.

Why it happens

When the source call fails or returns little, a model fills the gap with plausible values; grounding output in the returned payload removes the gap it fills.

TL;DR

Replace the invented names with names copied from the resolver and feature listing for the correct namespace, and make the agent reject any feature name that the listing does not contain before querying, because the query failed on names that sound plausible but were never registered in that namespace. Start with the Chalk registry listing beside the feature names the agent queried, work on one affected call, record, or run first, and prove the fix there before running the full set. Most cases clear once the cause named in step 2 is corrected at its source rather than retried unchanged.

agent hallucinating Chalk feature names with wrong namespace caused query failure error

Use this when

• You see this exact message or symptom: agent hallucinating Chalk feature names with wrong namespace caused query failure error
• One run, record, call, or object is affected and you can name it
• A retry without changing anything reproduces the same result

Not for this skill when

• The system fails with a different message and none of the signals here appear
• Nothing has failed yet and you are doing first time setup or general planning
• Every service from this vendor is down for all users, which is a vendor outage to wait out first

Steps

1. Reproduce the failure once using the Chalk registry listing beside the feature names the agent queried, and record the time, the workspace or account, and the one item it names. Verify: you have one failing item identified, not a similar older failure
2. Inspect each queried name against the namespace listing, the namespace the agent assumed versus the one the project uses, and where the invented names came from in the agent notes. Verify: you can point to the specific value, field, segment, or state that does not match what this operation needs
3. Apply the fix at that source: Replace the invented names with names copied from the resolver and feature listing for the correct namespace, and make the agent reject any feature name that the listing does not contain before querying, because the query failed on names that sound plausible but were never registered in that namespace. Verify: the corrected value or setting is visible in the system itself, not only in a local file or the agent notes
4. Re-run the original operation on the single affected item first. Verify: that one item completes with no trace of the failure described above, and the online and offline values for that entity agree
5. Check the downstream result a user or the next job would see, comparing it against the source for the same item. Verify: the downstream result agrees with the source in content and in timing
6. Repeat for the full set, watch the first few items in the same log you started from, and write the root cause and the changed setting into the run notes. Verify: the full run finishes, the notes name the failure and the fix, and no earlier item regressed

Variant phrasings

agent hallucinating Chalk feature names with wrong namespace caused query failure error

The subject-first phrasing of the same failure. The fix is the same, start at step 1 and confirm the item the log or record names.

Tool-first phrasing of this failure

The phrasing searchers use once they know which system raised it. It is the same underlying problem, not a separate bug.

Why does this keep happening after a retry

The repeat-occurrence phrasing. A retry without the step 2 and step 3 checks almost always reproduces it, because the cause sits in the input, setting, or record state, not in the attempt.

Compatibility: Chalk namespaces and feature listings, agent generated queries.

Why it happens

Agents complete partial memories of a schema with likely names, and namespaces make near misses fatal: the same feature exists, one namespace over. Grounding the name in a live listing is the only reliable check.
