Drop a task card in a list → Sergio picks it up, explores your codebase, and posts an implementation plan as a comment. Add feedback, move the card back, and iterate. When you're happy, move it to the Development list → Sergio creates a worktree, writes the code, runs tests, and opens a draft PR on GitHub.

It's a tool that can be used by teams of devs and product managers to cover the knowledge gaps between non technical and technical planning.

All triggered by dragging cards. It's basically Claude Code running as an autonomous teammate on a $5/month VM, orchestrated through Trello. The two-user sandbox architecture keeps the AI isolated from secrets and credentials (similar to OpenClaw's approach to secure agentic coding).

The roadmap includes pluggable engine support (OpenCode, Codex) and MCP servers for reading Google Docs, Figma, and Notion directly from cards.
