What
When the automatic pull-request-fixing flow can't subscribe a session to GitHub pull-request webhooks (notifications GitHub sends about PR activity), and the reason isn't simply that the GitHub app isn't installed, Claude Code now shows the specific detail explaining why, trimmed to 300 characters, in both the flow itself and its warning banner. Previously it only showed the generic message "Couldn't subscribe this session to PR webhooks."
Why
This gives users a concrete reason when webhook subscription fails, instead of an unhelpful generic message that gave no clue about what went wrong.
