# AgentLite Tool Suite

A comprehensive tool suite for AgentLite, inspired by kimi-cli's tools, with configuration support for enabling/disabling individual tools.

## Overview

This tool suite provides:

- **File Operations**: Read, write, edit, search files
- **Shell Execution**: Execute shell commands
- **Web Access**: Fetch URLs and search the web
- **Multi-Agent**: Task delegation and subagent creation
- **Utilities**: Todo lists and thinking tools
- **Configuration**: Fine-grained control over which tools are available

## Installation

The tool suite is included with AgentLite. No additional installation required.

## Quick Start

```python
from agentlite.tools import ConfigurableToolset, ToolSuiteConfig
from agentlite import Agent, OpenAIProvider

# Create toolset with default config (all tools enabled)
toolset = ConfigurableToolset()

# Create agent with tools
provider = OpenAIProvider(api_key="your-key", model="gpt-4")
agent = Agent(
    provider=provider,
    system_prompt="You are a helpful assistant.",
    tools=toolset.tools,
)
```

## Configuration

### Basic Configuration

```python
from agentlite.tools import (
    ToolSuiteConfig,
    FileToolsConfig,
    ShellToolsConfig,
)

# Disable specific tools
config = ToolSuiteConfig(
    file_tools=FileToolsConfig(
        tools={"WriteFile": False, "StrReplaceFile": False}
    )
)
toolset = ConfigurableToolset(config)
```

### Disable Entire Tool Groups

```python
# Disable all shell tools
config = ToolSuiteConfig(
    shell_tools=ShellToolsConfig(enabled=False)
)
toolset = ConfigurableToolset(config)
```

### Custom Tool Settings

```python
config = ToolSuiteConfig(
    file_tools=FileToolsConfig(
        max_lines=500,
        max_bytes=50 * 1024,  # 50KB
        allow_write_outside_work_dir=False,
    ),
    shell_tools=ShellToolsConfig(
        timeout=60,
        blocked_commands=["rm -rf", "sudo"],
    ),
)
```

### Dynamic Configuration

```python
# Create toolset
config = ToolSuiteConfig()
toolset = ConfigurableToolset(config)

# Disable tools and reload
config.file_tools.disable_tool("WriteFile")
config.shell_tools.enabled = False
toolset.reload()
```

## Available Tools

### File Tools

| Tool | Description | Config Options |
|------|-------------|----------------|

| `WriteFile` | Write or append to files | `allow_write_outside_work_dir` |
| `StrReplaceFile` | Edit files using string replacement | `allow_write_outside_work_dir` |
| `Glob` | Search files using glob patterns | `max_glob_matches` |
| `Grep` | Search file contents with regex | - |
| `ReadMediaFile` | Read images and videos | `max_size_mb` |

### Shell Tools

| Tool | Description | Config Options |
|------|-------------|----------------|
| `Shell` | Execute shell commands | `timeout`, `blocked_commands` |

### Web Tools

| Tool | Description | Config Options |
|------|-------------|----------------|

## Safety Features

### Path Security

- Files outside the working directory require absolute paths
- Optional restriction on writing outside working directory
- Path traversal protection

### Shell Security

- Configurable command timeout
- Blocked command list
- No shell injection (uses `execve` style execution)

### Resource Limits

- File size limits
- Line count limits
- Glob match limits
- HTTP content size limits

## Examples

### Safe Configuration for Untrusted Agents

```python
from agentlite.tools import ToolSuiteConfig, FileToolsConfig, ShellToolsConfig

# Safe config - read-only file access, no shell
safe_config = ToolSuiteConfig(
    file_tools=FileToolsConfig(
        allow_write_outside_work_dir=False,
    ),
    shell_tools=ShellToolsConfig(enabled=False),
)

toolset = ConfigurableToolset(safe_config)
```

### Using Individual Tools

```python
from agentlite.tools.file import ReadFile, Glob
from pathlib import Path

# Create tools directly
read_tool = ReadFile(work_dir=Path("."))
glob_tool = Glob(work_dir=Path("."))

# Use tools
result = await read_tool.read({"path": "README.md"})
if not result.is_error:
    print(result.output)

result = await glob_tool.glob({"pattern": "*.py"})
if not result.is_error:
    print(result.output)
```

### Configuration from File

```python
import json
from agentlite.tools import ToolSuiteConfig

# Load config from file
with open("tool_config.json") as f:
    config_dict = json.load(f)

config = ToolSuiteConfig.model_validate(config_dict)
toolset = ConfigurableToolset(config)
```

## API Reference

### Config Classes

#### `ToolSuiteConfig`

Main configuration class for all tools.

```python
class ToolSuiteConfig(BaseModel):
    file_tools: FileToolsConfig
    shell_tools: ShellToolsConfig
    web_tools: WebToolsConfig
    multiagent_tools: MultiAgentToolsConfig
    misc_tools: ToolGroupConfig
```

class FileToolsConfig(ToolGroupConfig):
    max_lines: int = 1000
    max_line_length: int = 2000
    max_bytes: int = 100 * 1024
    allow_write_outside_work_dir: bool = False
