Crucible
Open source AI development environment — specialized persona agents coordinating through a structured software lifecycle
Crucible is an open source AI-assisted development environment that runs in VS Code with Claude Code. It coordinates specialized AI persona agents through a structured software development lifecycle — requirements, design, implementation, testing, security, and deployment.
Instead of one AI session trying to hold an entire project in context, Crucible breaks work into tasks handled by specialized personas. Each persona has domain-specific instructions, its own MCP tools, and access to shared project documentation. Work flows through structured handoffs with quality gates at each stage.
Key capabilities:
- Specialized AI personas for each phase of development
- Task management with handoffs and quality gates
- Knowledge graph and semantic search across project artifacts
- Document templates with structured frontmatter
- VS Code extension with persona sidebar and task board
