Shell
Open-source Office suite built for AI agents: a single binary (no Office install) that creates, reads and edits Word, Excel and PowerPoint from the command line, with built-in HTML/PNG rendering, an Excel formula engine, template merge and an MCP server.
Why it's interesting
I picked it because it fixes agents' blind spot with Office documents: without rendering, an agent generating slides flies blind — here the render → look → fix loop lives inside the binary and works headless in CI too. And the core is written in C#/.NET, which I quite like.
