+#### Claude Code Integration
+
+The `claude-to-deerflow` skill lets you interact with a running DeerFlow instance directly from [Claude Code](https://docs.anthropic.com/en/docs/claude-code). Send research tasks, check status, manage threads — all without leaving the terminal.
+
+**Install the skill**:
+
+```bash
+npx skills add https://github.com/bytedance/deer-flow --skill claude-to-deerflow
+```
+
+Then make sure DeerFlow is running (default at `http://localhost:2026`) and use the `/claude-to-deerflow` command in Claude Code.
+
+**What you can do**:
+- Send messages to DeerFlow and get streaming responses
+- Choose execution modes: flash (fast), standard, pro (planning), ultra (sub-agents)
+- Check DeerFlow health, list models/skills/agents
+- Manage threads and conversation history
+- Upload files for analysis
+
+**Environment variables** (optional, for custom endpoints):
+
+```bash
+DEERFLOW_URL=http://localhost:2026            # Unified proxy base URL
+DEERFLOW_GATEWAY_URL=http://localhost:2026    # Gateway API
+DEERFLOW_LANGGRAPH_URL=http://localhost:2026/api/langgraph  # LangGraph API
+```
+
+See [`skills/public/claude-to-deerflow/SKILL.md`](skills/public/claude-to-deerflow/SKILL.md) for the full API reference.

 ### Sub-Agents
 
 Complex tasks rarely fit in a single pass. DeerFlow decomposes them.
