Ramp developed its own background coding agent called Inspect to enhance coding efficiency. Inspect operates in a sandboxed virtual machine environment, integrating essential tools and context for backend and frontend tasks. For backend work, it runs tests and reviews telemetry, while for frontend tasks, it visually verifies results with screenshots and live previews. This setup ensures that Inspect is only limited by its model intelligence, not by missing resources. Speed is a priority for Inspect sessions, which start quickly due to pre-session preparations. Currently, around 30% of all pull requests in Ramp’s repositories are generated by Inspect, indicating rapid internal adoption. The team focused on user needs and allowed Inspect to function in public spaces to encourage organic usage. They also aim to make Inspect's functionality replicable, providing a specification for others to build similar tools. The execution environment is critical, and Ramp uses Modal’s cloud platform to rapidly spin up development environments. They maintain an image registry that builds images every 30 minutes to keep data synchronized. Each coding session starts from a snapshot, ensuring minimal lag in repository updates. For agent functionality, Ramp recommends using OpenCode, an open-source coding agent that allows for extensive customization and has a fully typed SDK. To enhance performance, Ramp has implemented strategies for session management, including queuing follow-up prompts and allowing agents to spawn new sessions autonomously. They also emphasize building an API that accommodates various client inputs, leveraging Cloudflare’s Durable Objects for efficient session management. Each session operates independently, ensuring high performance even under heavy load.
