Score: 6.3/10 (Innovation: 6, Technical: 6, Documentation: 7, Utility: 6)

Mycelium is a plugin for AI coding agents like Claude Code that forces structured discovery before building, ensuring the right thing is built by asking questions about purpose, audience, and assumptions. It's interesting because it addresses a common pain point of AI-generated code that solves problems nobody has, using a scale and diamond framework to guide decisions.

Target audience: backend devs, frontend devs, solo developers, small teams
