What Crucible Alpha is
Crucible Alpha is an early release that came out of a couple weeks of intensive building. It works, it provides real productivity gains, and it represents only the tip of the iceberg of what's possible with structured AI development.
It's a best-effort system. The agents do a good job of following the workflow, creating documents, and managing tasks — but it's not 100% automated. You are an active participant, not a passive observer.
Set your expectations: Think of each agent as a capable but new team member. They'll do good work, but they need direction. You'll sometimes need to remind them to create tasks, update documents, or search the knowledge base. This is by design — Crucible Pro will lock this down with enforced structure and quality gates.

How to work with agents
Crucible gives you specialized AI personas — requirements, design, architecture, implementation, testing, security, DevOps, and more. Each one has a full chat interface through Claude Code and access to specialized MCP tools.
Treat each agent like a person. Ask questions. Give feedback. Push back on decisions you disagree with. The agents work best when you're actively guiding them, not just watching.
The key things you need to do:
- Create tasks — tell the agent what you want built, and ask it to create a Crucible task using the MCP tools
- Remind agents to use MCP functions — sometimes the LLM will try to do things manually instead of using Crucible's tools. Nudge it: "use the Crucible tools to create that task" or "search the knowledge base first"
- Ensure documents get created — requirements, designs, and architecture docs should be written as part of the workflow. If the agent skips this, ask for it
- Complete tasks — when work is done, make sure the agent marks the task as complete with proper documentation
- Search before creating — remind agents to search the knowledge base for existing work before starting something new
- Review and sign off — the quality gates are there for a reason. Review what agents produce before moving on
Tips for getting the most out of it
What to expect
Crucible Alpha will sometimes surprise you with how well it handles complex multi-file development. It will also sometimes forget to update a task or skip a documentation step. That's normal at this stage.
The system is genuinely useful — it was used to build significantly more complex systems on top of itself. But it requires an engaged human operator who understands what good software development looks like.
Crucible Pro is in active development and will address these gaps with enforced process structure, locked-in quality gates, multi-LLM support, and predictable file organization. Alpha is the foundation.
