Shadcn Flow 2 Block

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A top down agent tree laid out by dagre, with a header model picker and a Run test that tallies passed, failed and skipped steps

When to use

An editable node canvas for automation workflows or AI agent steps, with a side inspector per step
A run view for a scheduled data pipeline: task states, retries and a human approval gate
A driver map that ties initiatives to the input metrics and north star they are meant to move

When not to use

A left to right automation with step owners, undo history and a minimap: use the Automation Builder block
Watching a live AI run and answering its approval prompts as they arrive: use the Approval Run Console block
An overview page of KPI tiles, charts and work lists with no editable node graph: use the Dashboard blocks
A first run setup sequence that walks a new user through screens one at a time: use the Onboarding blocks
Operating live AI agent runs: tool permissions, approvals and evaluation reports: use the Agents blocks

Agent notes

Replace SEED and AGENT in data.tsx; INITIAL_EDGES is derived from each entry's parent and branchLabel, and layoutTree places every node
runTest replays the RECORDED_RUN fixture down the AGENT.testPath branch and calls no service; a step with no fixture fails
ModelSelect retitles the first claude app step, and MODEL_OPTIONS hardcodes each model's token and cost figures
Graph edits stay in local useNodesState and useEdgesState; no block persists nodes or edges, so wire your own load and save
Each block fills h-svh under its own header bar; swap it for a parent owned height when you mount it inside an app shell
Requires @xyflow/react; flow-canvas.tsx imports its stylesheet and FLOW_THEME maps its colors onto your theme tokens
