WakaWiki is a Rust-based CLI that uses LLM agents to auto-generate and maintain codebase documentation by reading files, searching patterns, and writing structured docs. It supports multiple LLM providers (OpenAI, Anthropic, DeepSeek, local) and integrates with GitHub Actions, positioning itself as a low-friction alternative to manual docs.

One insight: Zero revenue signals, minimal network traction (3 stars, 2 HN points), and no founder audience apparent—this is a very early technical experiment with no proven demand beyond the builder's own use case.
