Add workflow to post Dependabot alerts to Slack#20
Merged
Conversation
Manual sync of the workflow from the internal repo (no version bump). Fires on the dependabot_alert event and posts a Block Kit message to a Slack incoming webhook, guarded to the public repo. Requires the SLACK_WEBHOOK_URL secret.

Summary
This is a CI only change, not a release, so I'm not bumping the version. I'm just syncing over this file from https://github.com/Hyperbase/airtable-mcp-cli-internal/pull/31.
Claude summary
This uses the SLACK_WEBHOOK_URL secret which is already set on this repo.
Test Plan
No additional testing here. Verified in the internal PR (Hyperbase/airtable-mcp-cli-internal#31): event/action types, payload field paths (against GitHub's REST schema and a live alert), and that the jq-built Slack payload is valid JSON. A real
dependabot_alertevent can't be fired on demand, so the first real alert is the true test.I also verified the curl works with the webhook URL in question.
