Run support queries and bug checks from Slack threads
Doozy, a Slack agent, takes tasks from support staff and runs them against Postgres, Stripe, GitHub and Linear in a sandbox, then posts results in the thread; 13 people use it daily.
Done with a custom-built or unnamed agent
- What they did
- At Spur, support staff mention Doozy in a Slack thread with a task. It runs in a fresh sandbox (E2B) holding no credentials, while gateways outside add them per request. It queries Postgres, Stripe, GitHub, Linear, PostHog, MCP servers or the web, then posts results and files back in the thread. Destructive tools start denied until owners enable them.
- How it went
- 13 people at Spur use it daily, mostly support and success rather than engineers, and the author calls it a critical part of the team. The first version was hacky and barely read files sent in a thread.
- Worth knowing
- Keep credentials outside the sandbox and deny destructive tools by default; the author says injection can still misuse granted tools, though it can't leak a key.
Try it yourself with Claude Code
Set up a helper I can hand support tasks to. When I describe a problem, like [a customer's failed payment or a suspected bug], look it up using read-only access to [your database, Stripe, GitHub and Linear] and write up what you found with links to the records. You're done when you've given me a short summary I could post in a Slack thread. Never change or delete any data, and pause and show me anything you'd write or send before doing it.
