Nanostack

Nanostack is a set of skills that adds a team style review process to AI coding agents, aimed at people building software with AI who are not engineers. The agent still writes the code, and Nanostack runs the checks a real team would, then reports each result in plain words. The default sprint runs through a series of phases. Think questions the idea and narrows it to the smallest version worth building, Nano plans the work, the agent builds, and then Review checks for mistakes, Security runs a safety check, QA tests the result by using it, and Ship prepares the pull request. Each phase saves a short note as a plain file on the user's computer, and the next phase reads it. Users can add their own phases or create custom skills to extend the sprint. It works with Claude Code, Cursor, OpenAI Codex, OpenCode and Gemini CLI, which each have a verified adapter in the repository, and because the skills are plain text other agents can load them too. Installation is a single npx command. The site states that it is free and open source, runs on the user's computer, works with the agent the user already has, and has no Nanostack cloud, so no plan prices are published.
