Agent Flow

Agent Flow

Real-time visualization of Claude Code agent orchestration. Watch your agents think, branch, and coordinate as they work. [Demo video here](https://www.youtube.com/watch?v=Ud6eDrFN-TA).


Why Agent Flow?

I built Agent Flow while developing [CraftMyGame](https://craftmygame.com), a game creation platform driven by AI agents. Debugging agent behavior was painful, so we made it visual. Now we're sharing it.

Claude Code is powerful, but its execution is a black box — you see the final result, not the journey. Agent Flow makes the invisible visible:

• Understand agent behavior — See how Claude breaks down problems, which tools it reaches for, and how subagents coordinate
• Debug tool call chains — When something goes wrong, trace the exact sequence of decisions and tool calls that led there
• See where time is spent — Identify slow tool calls, unnecessary branching, or redundant work at a glance
• Learn by watching — Build intuition for how to write better prompts by observing how Claude interprets and executes them

Features

• Live agent visualization: Watch agent execution as an interactive node graph with real-time tool calls, branching, and return flows
• Auto-detect Claude Code sessions: Automatically discovers active Claude Code sessions in your workspace and streams events
• Claude Code hooks: Lightweight HTTP hook server receives events directly from Claude Code for zero-latency streaming
• Multi-session support: Track multiple concurrent agent sessions with tabs
• Interactive canvas: Pan, zoom, click agents and tool calls to inspect details
• Timeline & transcript panels: Review the full execution timeline, file attention heatmap, and message transcript
• JSONL log file support: Point at any JSONL event log to replay or watch agent activity
