UnknownUnknown. This template uses community nodes we can't verify statically. Uses community nodes that can't be verified statically (unverified community packages are off by default in 3.0). Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 18 nodes and runs on Slack events. Along the way it connects Slack, Anthropic Chat Model and Coresignal Api (community).

- Fetch Job Details from Coresignal (Coresignal): search es dsl (job)
- Post Acknowledgement on Slack (Slack): uses Slack
- Extract Job ID (Code): runs custom JavaScript code
- Retrieve Job Data from Coresignal (Coresignal): work with job

Services it uses
Before you upgrade to n8n 3.0
We can't fully verify this one: it relies on 1 community package, and n8n 3.0 turns unverified community packages off by default (N8N_UNVERIFIED_PACKAGES_ENABLED=false).
- Check that n8n-nodes-coresignal-api is verified or supports 3.0 (used in Fetch Job Details from Coresignal, Retrieve Job Data from Coresignal, Search Employees in Coresignal).
- Also check Slack Trigger requires a signing secret on the Slack API credential.
