agent hallucinating early stopping epoch not in logs caused report failure error

Not specified by the original author.

TL;DR

Take the epoch from the training log or not at all: the agent reported an early stopping epoch that appears in no log, so extract the stop epoch from the recorded metric history, and where the history is absent, report the stop as unrecorded. Early stopping leaves a precise trace: the last logged epoch and the best epoch in the metric history. An epoch that matches neither is an invention, however reasonable it sounds.

agent hallucinating early stopping epoch not in logs caused report failure error

Use this when

• The check or run fails with this symptom: an agent hallucinates an early stopping epoch not in the logs and the report fails.
• You are working on an agent workflow reporting training outcomes including early stopping behaviour and the failure repeats on the same data or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A run whose logs were rotated away, where the epoch is honestly unrecoverable and must be reported as such.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Read the run metric history and note the last epoch and the best scoring epoch. Verify: the two candidate epochs are established from data
2. Compare the agent reported epoch with both. Verify: the reported value matches neither, confirming the invention
3. Correct the report with the logged best epoch and the stop epoch, labelled distinctly. Verify: the report now cites log derived values
4. Change the workflow so epoch fields are extracted by code from the history. Verify: reported epochs always come from records
5. Where a run has no history, output unrecorded for the epoch. Verify: the gap is explicit in the report

The variant naming the failing stage or tool directly.

Compatibility: Training metric histories in experiment trackers, agent reporting workflows

Why it happens

Early stopping epochs feel inferable from patience settings and run length, and an agent asked for the number will produce the plausible one. Patience counts from the best epoch, restores and logging gaps shift the arithmetic, so the inferred number is routinely wrong in a way readers cannot detect without the history.

Edge cases / pitfalls

• Best epoch and stop epoch are different numbers; reports that use one word for both create this error even with honest data.
• A run that hit a step limit did not early stop, whatever its curve looks like; check the termination reason.

TL;DR

Fix this in synthetic data agent workflow by acting on the exact message first: require the release gate to read the full evaluation report status from the service, check that every named metric section is present and marked complete, and block release automatically when the report is partial, failed or older than the dataset version being released. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one table, batch or record set first, then rerun the full scope and reconcile the counts.

agent hallucinated privacy pass from a partial evaluation report - synthetic data released early

Use this when

• The operation in synthetic data agent workflow fails with this exact message or symptom: agent hallucinated privacy pass from a partial evaluation report - synthetic data released early.
• The same failure repeats on retry with unchanged inputs.
• Generation, validation or export 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 error 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 synthetic data agent workflow, and copy the full message plus the table, column or job involved into the run notes. Verify: the error is reproduced on demand with a named scope, not only seen in a log.
2. Apply the specific fix for this error: require the release gate to read the full evaluation report status from the service, check that every named metric section is present and marked complete, and block release automatically when the report is partial, failed or older than the dataset version being released. Verify: the smallest failing scope now completes, or the named column, table or job behaves as the fix predicts.
3. Check the neighbouring tables, columns or jobs that share the same config, schema 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 synthetic data agent workflow 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, distributions or status against the source in synthetic data agent workflow 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 partial report contains passing results for the metrics that finished, and an agent summarising only what it can see reports a pass for checks that never ran, which a completeness gate prevents.

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

TL;DR

Ground every reported number in a fetched record: the agent invented runs because it generated the report's shape first and filled values from plausibility instead of queries. Require each reported run to carry an id that resolves on the tracker, verify a sample of the report's claims against live fetches, and block the report when any cited id fails to resolve.

agent hallucinating experiment results for runs that never existed and reporting failed metrics as passed

Use this when

• The run or call fails with this symptom: agent hallucinating experiment results for runs that never existed and reporting failed metrics as passed.
• You are working on an agent reporting experiment results to a team or a log and the failure repeats on the same run or configuration.
• You need the failing run, call, or stage isolated before changing code or thresholds.

Not for this skill when

• A report over runs that were deleted after being fetched earlier, where the fix is labelling historical data rather than treating it as invented.
• The error text names a different tool, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Extract every run id and metric value from the draft report and resolve each id against the tracker. Verify: unresolvable ids are listed
2. For resolved runs, compare the reported metrics and statuses with the tracker's actual values. Verify: value mismatches are listed separately from missing runs
3. Regenerate the report from fetched records only, with the fetch results, not the model's memory, as the data source. Verify: every claim in the new report maps to a fetched record
4. Add a verification pass that fails the report if any citation does not resolve, and run it before delivery. Verify: the gate runs and passes on the corrected report

Variant phrasings

agent hallucinated experiment results runs never existed

The verbatim phrasing.

agent reported failed metrics as passed invented runs

The false-pass phrasing.

agent experiment report not grounded verify run ids

The grounding phrasing.

Compatibility: Agent reporting pipelines that must cite tracker data for every claim

Why it happens

A language model asked for results will produce results-shaped text whether or not it looked anything up, and plausible numbers for plausible runs are its default output. Without a fetch-and-cite discipline enforced mechanically, invention is indistinguishable from reporting until someone checks an id.

Edge cases / pitfalls

• Status flips, failed reported as passed, are the most damaging invention; verify statuses even when ids resolve.
• Keep fetch snapshots with the report so later checks compare against what the agent saw, not a changed tracker.
