Cohort-specific rate/pagination
Slack conversations.history default limit 15 maximum limit 15 May 29 2025
Sync completes without errors but silently indexes only 15 messages per page.
Agent Quick Fix
Repair against the current Slack Web API contract, then keep the change narrow and source-backed.
Product: Slack Web API
Current-contract area: Slack conversations.history default/max limit drops to 15
Likely root cause: Sync completes without errors but silently indexes only 15 messages per page.
Repair direction: Verifier checks backoff, pagination completeness, and installation-aware behavior under the current limits. Verify complete synchronization under each cohort without hard-coding one global throttle.Symptom
Sync completes without errors but silently indexes only 15 messages per page.
Why This Happens
The code can work for existing/internal installations yet fail for newly created or unlisted apps; account cohort and current service policy are external.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
