Bkit Claude Code

bkit is an open source plugin that adds a structured development workflow to Claude Code, with support for Gemini CLI as well. It applies a plan, do, check, act cycle to AI generated code: the plugin produces a design document first, builds against it, measures how closely the generated code matches the design, and automatically repairs gaps over up to five improvement cycles per session. It is aimed at first time vibe coders, solo developers and team leads who want AI output held to a specification. Installation is two commands through the Claude Code plugin marketplace. The current README lists dozens of skills and specialist agents, eleven quality gates covering match rate, conventions, test coverage and security, and memory that carries decisions across sessions. A team command has a lead agent split work across several specialist agents running in parallel, in leader, swarm or council modes. Sprint management divides a release into sprints sized to fit one Claude Code session and resumes after interruptions, and natural language commands are recognized in eight languages. It runs on macOS, Linux and Windows. bkit is free. The source is published on GitHub under the Apache 2.0 license, and no paid tier is listed on the website. Use of Claude Code or Gemini CLI themselves is billed separately by those providers. The plugin is developed by DubDubDub Corp., and the repository has moved from its original popup studio organization. Recent versions require Claude Code 2.1.143 or later, and older versions reject the plugin manifest during installation.
