• Ship the full experience: Build in-product chat, streaming responses, permission-aware APIs, and our external MCP server.
• Make quality measurable: Build evals, catch regressions, and use production feedback to improve quality, latency, and cost.
• Help shape the platform: Make decisions about how we build, deploy, and run agents as the product grows.
