Quick Setup (< 1 hour)

You can use Mistle to run autonomous coding agents that handle routine development work in the background. The agents work in sandboxed environments with full access to your codebase, tools, and services. They can investigate bugs, increase test coverage, refactor code, and build features while verifying their own output. Teams can assign tasks through Slack, GitHub, or Linear and get results with minimal supervision since agents validate their work before handoff.
