Test Mode lets you have a conversation with an agent inside the dashboard, exactly the way Slack would, but without posting anything to a real channel. MCPs work, boss delegation works, memory works - it’s a safe sandbox for iterating.Documentation Index

Open the Test tab
- Go to the agent’s detail page
- Click Test in the tab bar
- You’ll see an empty conversation pane
Start a test session
Type your prompt at the bottom and press Enter:Use MCPs in the test
MCPs assigned to the agent work in Test Mode. If the agent hasplaywright, asking it to browse a URL actually opens a browser. If it has notion, it reads real Notion pages. No mocking - real tools, real side effects.
Side effects are real. Test deletes, writes, or postings are not isolated. Use a sandbox workspace for destructive MCPs.
Delegate to other agents
Type@another-agent-slug in your message and Test Mode routes the request through your Boss agent, exactly like Slack would. You’ll see:
- Your original message
- Boss’s delegation line
- The specialist’s reply streaming in
- Boss’s summary
Inspect the trace
Each turn shows:- Tool calls - chips with the tool name, args, and result
- Cost - total tokens and dollar estimate
- Duration - wall-clock time for the turn
- Session ID - click to tie back to the log stream
When to use Test Mode
- Before first deployment - confirm the agent replies the way you expect
- After a Coach-driven change - sanity-check the new prompt
- When an MCP seems off - reproduce without the Slack round-trip
- Debugging delegation - exercise
