CodeZero - Give coding agents the context they're missing

Hey Product Hunt! We built CodeZero around a problem we kept seeing with AI-assisted development: coding agents can write code quickly, but on an existing system, the difficult part often happens before the first edit. Where is this feature already implemented? Which other repositories are involved? What depends on this code? What else could break if we change it? In practice, a lot of that context gets discovered while the agent is already implementing the change. CodeZero is our attempt to move that understanding earlier in the workflow. It runs inside VS Code and gathers context across the repositories your organisation connects. You can trace how features are implemented, explore dependencies across repositories, investigate the codebase, and review a plan before implementation begins. The idea is simple: Understand → Plan → Build We’re not trying to replace the coding tools developers already use. CodeZero works alongside tools like Claude Code, Codex, and GitHub Copilot by giving that workflow a better understanding of the software that already exists. There’s a free plan, and I’d especially love feedback from developers working with larger or multi-repo codebases: Where does your coding agent lose context today?
