A new pr_open alert carries the head commit SHA of each open, non-draft, same-repository pull request. An action with auto enabled sends its webhook once for each pull request and head commit. An authors list limits which pull requests trigger it. The alert never changes repository health.
An optional actions block in the config adds buttons to alerts. POST
/api/actions/{id} checks that the repository and the current alert match,
then sends the alert as JSON to the configured webhook with an optional
bearer token. The request refuses cross-site callers like POST /refresh.
GET /api/state lists the actions and merges per-alert status rows from an
optional status_url, cached for 10 seconds. Without an actions block the
API output does not change.
The ghtracker_action_requests_total counter records each result.
