# Use Tools and Skills

This tutorial shows you how to configure and use tools and skills in DeerFlow to give the agent access to web search, file operations, and domain-specific capabilities.

## Configuring tools

Add tools to `config.yaml`:

```yaml
tools:
  # Web search
  - use: deerflow.community.ddg_search.tools:web_search_tool

  # Web content fetching
  - use: deerflow.community.jina_ai.tools:web_fetch_tool

  # Sandbox file operations
  - use: deerflow.sandbox.tools:ls_tool
  - use: deerflow.sandbox.tools:read_file_tool
  - use: deerflow.sandbox.tools:write_file_tool
  - use: deerflow.sandbox.tools:bash_tool
```

## Enabling skills

Enable skills through the DeerFlow app's extensions panel, or edit `extensions_config.json` directly.

**Via the app UI:**
1. Open the DeerFlow app
2. Click the Extensions/Skills icon in the sidebar
3. Find `deep-research` and toggle it on

## Using a skill for research

With the `deep-research` skill enabled, select it in the conversation input, then send a research request:

```
Do a deep research on the latest advances in quantum computing, focusing on practical applications.
```

The agent will run a multi-step research workflow including web search, information synthesis, and report generation.

## Using the data analysis skill

Enable `data-analysis`, then upload a CSV or data file and ask the agent to analyze it:

```
Analyze this CSV file and identify the top trends.
```

The agent will use the sandbox tools to read the file, run analysis, and produce charts.
