OVERVIEW
How Cairn works with Slack
Trigger agents from messages, post approvals and send run summaries to any channel. Connect Slack with OAuth 2.0 in about 2 min — no code required — and choose exactly which scopes each agent can use.
What agents can do
Approve or reject agent actions with one click
Thread-level run summaries
Slash commands to start any agent
Channel-scoped permissions
Permissions and audit
Every call an agent makes to Slack is recorded in the run trace with its inputs, outputs and the policy that allowed it. Revoke access at any time from the integrations page and running agents stop immediately.
