Buy Vs Build
Stop your AI coding agent from reinventing the invoice. An always-on buy-vs-build ruleset that reuses built-ins, platform features, and existing dependencies first, picks the tool that fits, vets dependencies before you own them, and records the decision. Works across Codex, Claude Code, Gemini, Cursor, Copilot, and more.
