The only AI coding agent that shows you exactly why it answered the way it did.

Prism Agent is a standalone terminal AI coding agent that makes the routing layer visible. The left pane shows a live knowledge graph that updates in real time as you work, showing exactly which domains activated and why.

What makes it different

Every other coding agent is a black box. You type a prompt, it thinks somewhere off-screen, and you get an answer with no visibility into why that answer happened.

Prism Agent makes the routing layer visible. You can see which domains activated, why they ranked highly, and how they relate to each other. You can also steer the agent directly by pinning domains you always want active or suppressing domains you do not want influencing the next turn. Prism Agent is not just answering your request. It is showing its work.

Configuration

Set one of these environment variables before starting the full TUI:

• ANTHROPIC_API_KEY
• PRISM_API_KEY

You can keep the key in a local .env file or export it in your shell.
