## TL;DR
Fix this in at-risk list agent workflow by acting on the exact message first: push the threshold filter into the score query itself so only at-risk accounts are returned, sort server side, limit the first pass to the worst scoring segment, and time each stage so the slow stage is fixed rather than the whole job retried. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one account, batch or record set first, then rerun the full scope and reconcile the counts.

agent timed out when agent tried to generate an at-risk account list - slow
```

## Use this when
- The operation in at-risk list agent workflow fails with this exact message or symptom: agent timed out when agent tried to generate an at-risk account list - slow.
- The same failure repeats on retry with unchanged inputs.
- Scoring, alerting or routing 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 at-risk list agent workflow, and copy the full message plus the account, measure 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: push the threshold filter into the score query itself so only at-risk accounts are returned, sort server side, limit the first pass to the worst scoring segment, and time each stage so the slow stage is fixed rather than the whole job retried. Verify: the smallest failing scope now completes, or the named account, measure or job behaves as the fix predicts.
3. Check the neighbouring accounts, measures 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 at-risk list 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, scores or status against the source in at-risk list 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
Fetching every account and filtering locally makes list generation scale with the whole portfolio, while a server side threshold filter scales with the at-risk set only.

## Variant phrasings

### agent timed out when agent tried to generate an at-risk account list - slow
The verbatim form searchers paste from the terminal or console. Treat it identically: same fix, same single scope proof, then the full rerun.

### How to fix - agent timed out when agent tried to generate an at-risk account list error timeout failure slow
The how-to phrasing for the same failure in at-risk list agent workflow. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### at-risk list agent workflow 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 sample scope but the full rerun still fails, a second account or record with the same fault is present; widen the scope in stages until the next failing item is found.
- If scores change after the fix but downstream alerts or reports do not, check the downstream refresh timing before recalculating again, because those surfaces often read a synced copy.
- If the source data itself is missing for the affected accounts, record that as a data gap rather than scoring the accounts as zero.

Compatibility: at-risk list 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.
