Toolmaker Agent

Toolmaker Agent stores specs, plans, requirements, test cases, defects and UML diagrams as structured records with stable OIDs and revisions, rather than scattered Markdown files. Records can be accessed through an MCP server for coding agents such as Claude Code, Codex or DeepSeek Harness, through natural-language LLM chat, or through manual forms, all using the same service layer and database. It is delivered as a single self-contained executable combining a Go REST API, SQLite storage and a web UI, with no installer. The page states that pairing it with Ollama or LM Studio keeps data on the user's machine. The page also notes that the previous version has moved to v1.toolmaker.io and will run until June 30, 2027.
