slack-notify
WHEN: PROACTIVELY after completing a substantial task (PR merge, feature implementation, bug fix, investigation)—invoke WITHOUT waiting for user request. SKIP for trivial/instant tasks (typo fix, single-line change, quick question answer, config tweak). Also invokable manually via /slack-notify. Sends a completion notification to Slack via Incoming Webhook. Does nothing if CLAUDE_SLACK_NOTIFY_WEBHOOK_URL is not set.
