+# Tool Use Guide
+
+## Overview
+
+The Tool Use feature allows agents to call external tools during training to enhance reasoning capabilities. ROLL uses the [GEM](https://github.com/axon-rl/gem) environment definition for environment interfaces, and Tool Use utilizes the [Tool Env Wrapper](https://axon-rl.github.io/gem/features/#wrappers) provided by GEM. Tools are extended based on the `gem.tools.base_tool.BaseTool` interface.
+
+### Core Components
+
+1. **BaseTool Interface** (`gem.tools.base_tool.BaseTool`): The fundamental interface that all tools must inherit from
+2. **Tool Env Wrapper** (`roll.pipeline.agentic.tools.tool_env_wrapper.ToolEnvWrapper`): A wrapper that adds tool calling capabilities to environments
+3. **Tool Registration Mechanism** (`roll/pipeline/agentic/tools/__init__.py`): Unified management and registration of available tools
+
+### Default Supported Tool Types
+
+Currently, ROLL supports three default tools:
+
+#### PythonCodeTool
+- **Function**: Execute Python code
+- **Purpose**: Mathematical calculations, data processing, algorithm implementation, etc.
+- **Implementation location**: `roll/pipeline/agentic/tools/python_code_tool.py`
+```python
+class PythonCodeTool(GEMPythonCodeTool):
+
+    def __init__(
+        self,
+        timeout: int = 5,
+        sandbox_type: str = "none",
+        keep_error_last_line: bool = False,
+        tool_instruction=None,
+        patterns=None,
+    ):
+        pass
+```
+
+#### SearchTool
+- **Function**: Search for external information
+- **Purpose**: Q&A systems, knowledge retrieval, fact verification, etc.
+- **Implementation location**: `gem.tools.search_tool.SearchTool`
+```python
+class SearchTool(BaseTool):
+    def __init__(self, num_workers=1, search_url=None, topk=3, timeout=TIMEOUT):
+        pass
+```
+
+#### McpTool
+- **Function**: Model Context Protocol tool
+- **Purpose**: Interact with external models or services
+- **Implementation location**: `roll.pipeline.agentic.tools.mcp_tool.MCPTool`
+```python
+class MCPTool(BaseTool):
+    def __init__(self, 
+                num_workers=1, 
+                server_url: Optional[str] = None, 
+                client: Optional[MCPClient] = None,
+                tool_names_subset: Optional[List[str]] = None,
+                custom_prompt: Optional[str] = None):
+        pass
+```
+
+## Tool Registration and Custom Extensions
+
+Tool registration is located in `roll/pipeline/agentic/tools/__init__.py`. Users can customize tool implementations as needed and register them using `register_tools`.
+
+### Custom Tool Example
+
+```python
+from gem.tools.base_tool import BaseTool
+
+class MyCustomTool(BaseTool):
+    """Custom tool example"""
+
+    def __init__(self, **kwargs):
+        super().__init__(**kwargs)
+
+    def execute(self, input_data):
+        # Implement the specific logic of the tool
+        return {"result": "custom tool output"}
+```
+
+## Tool Wrapper Configuration and Usage
+
+The tool wrapper code in ROLL is located at `roll/pipeline/agentic/env_manager/traj_env_manager.py:73`. When users customize env_manager, adding the wrapper enables tool calling capabilities for the environment.
+
+### YAML Configuration Example
+
+Configure the tools used by the environment through yaml files, as shown in the example (`examples/config/traj_envs_gem_math.yaml`):
+
+```yaml
+dapo_17k_with_python_code:
+  env_type: "roll_math"
+  max_steps: ${max_actions_per_traj}
+  max_tokens_per_step: ${max_tokens_per_step}
+  env_manager_cls: ${env_manager_cls}
+  agent_system_template: ${math_agent_system_template}
+  agent_template: ${math_agent_template}
+  env_config:
+    max_steps: ${max_actions_per_traj}
+    dataset_name: open-r1/DAPO-Math-17k-Processed
+    question_key: prompt
+    answer_key: solution
+  tool_wrapper:
+    wrapper_args:
+      tool_reward: 0
+      tool_success_reward: 0
+      max_tool_uses: 1
+    tool_configs:
+      - tool_id: python_code
+        tool_args:
+          timeout: 5
+          sandbox_type: none
+          keep_error_last_line: false
+```
+

+- **wrapper_args**: General wrapper parameters
+  - `tool_reward`: Tool calling reward value
+  - `tool_success_reward`: Reward value for successful tool execution
+  - `max_tool_uses`: Maximum number of tool calls
+- **tool_configs**: List of specific tool configurations

+
+![qa + search](../../../../static/img/qa_search.png)
+
+#### Search Engine Startup Method
+
+Before using SearchTool, you need to start the local search engine. Here we use the local dense retriever provided in search-R1 as the search engine. Detailed instructions are in [search-R1 documents](https://github.com/PeterGriffinJin/Search-R1/blob/main/docs/retriever.md).
+
+The local dense retriever in ROLL is located at `examples/qwen3_agentic_gem/start_retrieval_server.sh`.
+
+##### Data Preparation
+
+First, download the corpus and index files required for searching:
+
+```bash
+save_path=/the/path/to/save
+huggingface-cli download PeterJinGo/wiki-18-corpus --repo-type dataset --local-dir $save_path
+huggingface-cli download PeterJinGo/wiki-18-e5-index-HNSW64 --repo-type dataset --local-dir $save_path
+
+gzip -d $save_path/wiki-18.jsonl.gz
+cat $save_path/part_* > $save_path/e5_HNSW64.index
+```
+
+##### Start Search Engine
+
+```bash
+# Before running the script, modify the SAVE_PATH_RETRIEVER variable 
+# in start_retrieval_server.sh to your downloaded index and corpus directory path
+export SEARCH_URL="http://localhost:8000/retrieve"
+
+bash examples/qwen3_agentic_gem/start_retrieval_server.sh
+```
+
+##### Environment Variable Configuration
+
+Make sure to set the following environment variables:
+- `SEARCH_URL`: Search engine service address, default is `http://localhost:8000/retrieve`
+- `SAVE_PATH_RETRIEVER`: Local storage path for corpus and index files
