Repository permission issues
Fix PAT scopes, webhook / service-hook delivery, and connection errors.
Most "connected but silent" repos come down to a missing token scope or a webhook that isn't reaching us.
Azure DevOps
Check the PAT scopes
The Personal Access Token needs Code (read) and Pull request threads (read & write). A token missing thread write can read PRs but never post a verdict. Rotate it from Settings → Integrations → Azure DevOps.
Verify the service hook
codingassist.bot registers a service-hook subscription for Pull request created / updated. If it was removed on the ADO side, disconnect and reconnect the project to recreate it. See Connect Azure DevOps.
GitHub
Webhook secret mismatch
If deliveries are rejected as unauthorized, the webhook secret is stale. Rotate it — see Rotate webhook secret. Tokens and secrets are stored encrypted and never returned; rotating issues a fresh value.
