## TL;DR
Fix this in Slack by acting on the exact message first: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. 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.

auth token expired mid-Slack alert lookup error failed token refresh
```

## Use this when
- The operation in Slack fails with this exact message: auth token expired mid-Slack alert lookup error failed token refresh.
- 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 Slack, 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: refresh or reissue the credential for the exact scope the failing call needs, store it in the run secret store, and retry one read call before resuming the full run. Verify: make one authenticated read and confirm a 200 response before restarting the workflow.
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. Compare the result counts, decisions or alerts against the source in Slack so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in Slack 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.
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
Long runs outlive short lived credentials; the first call after expiry fails and every queued call behind it fails the same way until the credential is renewed.

## Variant phrasings

### auth token expired mid-Slack alert lookup error failed token refresh
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: auth token expired mid-Slack alert lookup error failed token refresh
The how-to phrasing for the same failure in Slack. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

### Slack 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: Slack 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.
