Hey Product Hunt! 👋 I built SpecLock because I was tired of my AI "helpfully" breaking my code. You tell Claude: "Never touch auth files" Three sessions later: *rewrites your entire auth flow* Sound familiar? SpecLock fixes this with active constraint enforcement. Not just memory — actual blocking. When you lock something, the AI gets stopped before the damage happens. The best part? It works everywhere: • Bolt.new (just say "install speclock" — no MCP needed!) • Claude Code (19 MCP tools) • Cursor, Lovable, Windsurf, Cline Free. Open source. Try it: https://github.com/sgroy10/speclock What constraint would you lock first?
