## What it does

DeerFlow is an agent platform built on LangGraph that orchestrates sub-agents for research, code execution and web browsing. The skill talks to it over HTTP: checks health, creates a thread, streams a run and pulls the final answer out of the SSE events. It also lists models, skills and agents, toggles skills on and off, reads memory and uploads files into a thread.

Before any request the skill resolves environment variables. `DEERFLOW_URL` defaults to `http://localhost:2026`, and `DEERFLOW_GATEWAY_URL` plus `DEERFLOW_LANGGRAPH_URL` (`$DEERFLOW_URL/api/langgraph`) derive from it. Nothing answers on that port and the health check fails — the skill then tells you the instance has to be started. Behaviour is set in `context`: flash skips thinking and planning, standard adds thinking, pro adds a plan, ultra also enables sub-agents. Quick questions fit flash; research wants pro or ultra.

A helper script ships with it: `scripts/chat.sh` checks health, creates a thread, streams the run and prints the result. Uploads accept PDF, PPTX, XLSX and DOCX and convert them to Markdown. Thread IDs stick around, so you can come back to a conversation later.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash

```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bytedance/deer-flow --skill claude-to-deerflow -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bytedance/deer-flow --skill claude-to-deerflow -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bytedance/deer-flow claude-to-deerflow
```

2. **Manually: put the files in place**
- File: `.github/skills/claude-to-deerflow/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bytedance/deer-flow --skill claude-to-deerflow -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bytedance/deer-flow --path skills/public/claude-to-deerflow
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bytedance/deer-flow --skill claude-to-deerflow -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/bytedance/deer-flow/tree/HEAD/skills/public/claude-to-deerflow/SKILL.md

## When to use it
- ask DeerFlow a question and get the answer in the terminal
- start a thread for a deep research task
- confirm the DeerFlow instance is up
- list available models, skills and agents
- upload a PDF or DOCX into a thread and reference it

## Example prompts
- Ask DeerFlow what changed in LangGraph and show me the answer
- Run a deep research task on the EV market in ultra mode
- Upload `report.pdf` to the thread and summarize it

description: "Interact with DeerFlow AI agent platform via its HTTP API. Use this skill when the user wants to send messages or questions to DeerFlow for research/analysis, start a DeerFlow conversation thread, check DeerFlow status or health, list available models/skills/agents in DeerFlow, manage DeerFlow memory, upload files to DeerFlow threads, or delegate complex research tasks to DeerFlow. Also use when the user mentions deerflow, deer flow, or wants to run a deep research task that DeerFlow can handle."

# DeerFlow Skill

Communicate with a running DeerFlow instance via its HTTP API. DeerFlow is an AI agent platform
built on LangGraph that orchestrates sub-agents for research, code execution, web browsing, and more.

## Architecture

DeerFlow exposes two API surfaces behind an Nginx reverse proxy:

| Service        | Direct Port | Via Proxy                        | Purpose                          |
|----------------|-------------|----------------------------------|----------------------------------|
| Gateway API    | 8001        | `$DEERFLOW_GATEWAY_URL`          | REST endpoints and embedded agent runtime |
| LangGraph-compatible API | 8001 | `$DEERFLOW_LANGGRAPH_URL`       | Agent threads, runs, streaming   |

## Environment Variables

All URLs are configurable via environment variables. **Read these env vars before making any request.**

| Variable                | Default                                  | Description                        |
|-------------------------|------------------------------------------|------------------------------------|
| `DEERFLOW_URL`          | `http://localhost:2026`                  | Unified proxy base URL             |
| `DEERFLOW_GATEWAY_URL`  | `${DEERFLOW_URL}`                        | Gateway API base (models, skills, memory, uploads) |
| `DEERFLOW_LANGGRAPH_URL`| `${DEERFLOW_URL}/api/langgraph`          | LangGraph API base (threads, runs) |

When making curl calls, always resolve the URL like this:

```bash
# Resolve base URLs from env (do this FIRST before any API call)
DEERFLOW_URL="${DEERFLOW_URL:-http://localhost:2026}"
DEERFLOW_GATEWAY_URL="${DEERFLOW_GATEWAY_URL:-$DEERFLOW_URL}"
DEERFLOW_LANGGRAPH_URL="${DEERFLOW_LANGGRAPH_URL:-$DEERFLOW_URL/api/langgraph}"
```

## Available Operations

### 1. Health Check

Verify DeerFlow is running:

```bash
curl -s "$DEERFLOW_GATEWAY_URL/health"
```

### 2. Send a Message (Streaming)

This is the primary operation. It creates a thread and streams the agent's response.

**Step 1: Create a thread**

```bash
````
