## What it does

Agent Flow renders Claude orchestration as an interactive node graph. Every tool call, its result, a branching decision and a subagent's return to its parent becomes a node on the canvas. Instead of reading logs line by line, you watch the run happen.

Events arrive through Claude hooks. The extension starts a local HTTP server, and the `PreToolUse` and `PostToolUse` hooks POST JSON to it with `curl`. Setup runs automatically on first open; to redo it, run `Agent Flow: Configure Claude Code Hooks` from the Command Palette. There is also a JSONL mode: point `agentVisualizer.eventLogPath` at a log file and the extension tails it, which suits post-hoc debugging and CI monitoring. Concurrent sessions get their own tabs.

You need VS Code 1.85 or later, the Claude CLI on your PATH, and Node.js. The hooks live in `~/.claude/settings.json` or a project-level `.claude/settings.json`, so if you already route those events somewhere else, check that automatic configuration did not overwrite your entries.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill agent-flow-visualization -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/agent-flow-visualization/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/agent-flow-visualization/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill agent-flow-visualization -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/agent-flow-visualization/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill agent-flow-visualization -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/agent-flow-visualization/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install reason-machines/trending-skills agent-flow-visualization
```

2. **Manually: put the files in place**
- File: `.github/skills/agent-flow-visualization/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill agent-flow-visualization -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/reason-machines/trending-skills --path skills/agent-flow-visualization
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/agent-flow-visualization/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add reason-machines/trending-skills --skill agent-flow-visualization -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/reason-machines/trending-skills/tree/HEAD/skills/agent-flow-visualization/SKILL.md

## When to use it
- see which tools an agent actually called
- find the branch where a run spawned a needless subagent
- replay a finished run from a saved JSONL log
- watch several Claude sessions at once
- share a recording of an agent run with a teammate

## Example prompts
- Open Agent Flow and connect to the running Claude session
- Configure Claude hooks so events stream into the visualizer
- Show the graph for `${workspaceFolder}/logs/agent-session.jsonl`
