Description
I built SpecMind, an open source developer tool for spec driven vibe coding. It keeps architecture and implementation aligned from the first commit instead of letting them drift apart.With AI assistants writing more of our code, projects move faster but architectural consistency is often lost. Each developer or AI can introduce new patterns, and after a few sprints, the structure becomes fragmented. SpecMind helps prevent that by generating and maintaining living architecture specs directly from your code.It works in three steps: 1. analyze – scans your codebase and generates .specmind/system.sm with architecture diagrams and relationships, 2. design – creates a spec describing how the feature will change the system, 3. implement – applies the spec, updates diagrams, and logs what changedAll specs are plain text files with Markdown and Mermaid diagrams, stored alongside your code. A VS Code extension lets you preview them visually.Supports TypeScript, JavaScript, Python, and C#, with Go and Rust coming next. Works with Claude Code and Windsurf today, Cursor and Copilot soon.Demo: https://www.youtube.com/watch?v=4-9gQxw8DQURepo: https://github.com/specmind/specmindWould love to get feedback from engineers working on large or complex codebases.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
