OAuth refresh failed mid meeting prep agent lost Slack access brief not delivered

TL;DR

Fix this in meeting prep agent with Slack by acting on the exact message first: restore the Slack connection through the workspace connected account flow before rebuilding delivery, queue finished briefs locally while access is down, and deliver the queued briefs in order once Slack access returns instead of discarding them.. 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 meeting prep agent with Slack fails with this exact message: OAuth refresh failed mid meeting prep agent lost Slack access brief not delivered.
• The same failure repeats on retry with unchanged inputs.
• A call, review or send 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 meeting prep agent with Slack, and copy the full message plus the account, contact or meeting 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: restore the Slack connection through the workspace connected account flow before rebuilding delivery, queue finished briefs locally while access is down, and deliver the queued briefs in order once Slack access returns instead of discarding them.. Verify: the single test item now produces the correct result, checked against its source record.
3. Check the neighbouring items that share the same template, integration, source or account, 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 against the source system so a silent partial success is caught before sign off. Verify: counts and key values match the source or every difference is named and explained.
5. Rerun the original operation in meeting prep agent with 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

Delivery was the last step of the run and the only copy of the finished brief lived in that delivery attempt, so losing Slack access at that moment lost the brief itself.
