Mdlens is a CLI tool for efficient Markdown retrieval by AI agents, replacing common patterns like find, rg, and cat with a focused scout command that returns a bounded evidence pack from natural-language queries. It's interesting because it optimizes token spend and retrieval accuracy for agent workflows, backed by detailed evals showing reduced tool calls and costs.

Target audience: backend devs, AI/ML engineers, devops
