### Tools

| Tool | Description |
|------|-------------|

| `write_todos` | Update the todo list |

### Factory

```python
from pydantic_ai_todo import create_todo_toolset

def create_todo_toolset(
    storage: TodoStorageProtocol | None = None,
    *,
    id: str | None = None,
) -> FunctionToolset[Any]
```

**Parameters:**

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `storage` | `TodoStorageProtocol \| None` | `None` | Storage backend (defaults to in-memory) |
| `id` | `str \| None` | `None` | Optional unique ID for the toolset |

### Tool: read_todos

```python
async def read_todos() -> str
```

Read the current todo list state.

**Returns:** Formatted list of todos with status icons and summary.

### Tool: write_todos

```python
async def write_todos(todos: list[TodoItem]) -> str
```

Update the todo list with new items.

**Parameters:**

| Parameter | Type | Description |
|-----------|------|-------------|
| `todos` | `list[TodoItem]` | List of todo items |

Each todo item:
```python
{
    "content": str,      # Task description
    "status": str,       # "pending", "in_progress", "completed"
    "active_form": str,  # Present continuous form
}
```

**Returns:** Confirmation message with status counts.

### Types

```python
from pydantic_ai_todo import Todo, TodoItem, TodoStorage, TodoStorageProtocol

class Todo(BaseModel):
    content: str
    status: Literal["pending", "in_progress", "completed"]
    active_form: str

class TodoStorage:
    """Default in-memory storage."""
    todos: list[Todo]
```

### System Prompt

```python
from pydantic_ai_todo import get_todo_system_prompt

def get_todo_system_prompt(storage: TodoStorageProtocol | None = None) -> str
```

Generates dynamic system prompt showing current todos.

### Standalone Usage

```python
from pydantic_ai import Agent
from pydantic_ai_todo import create_todo_toolset, TodoStorage

# Simple usage
agent = Agent("openai:gpt-4.1", toolsets=[create_todo_toolset()])

# With storage access
storage = TodoStorage()
agent = Agent("openai:gpt-4.1", toolsets=[create_todo_toolset(storage)])
result = await agent.run("Create 3 tasks")
print(storage.todos)  # Access todos directly
```

## Console Toolset

File operation tools. Provided by [pydantic-ai-backend](https://github.com/vstorm-co/pydantic-ai-backend).

For full documentation, see [pydantic-ai-backend Console Toolset](https://vstorm-co.github.io/pydantic-ai-backend/concepts/console/).

### Tools

| Tool | Description |
|------|-------------|
| `ls` | List directory contents |
| `read_file` | Read file with line numbers |
| `write_file` | Create or overwrite file |
| `edit_file` | Replace strings in file |
| `glob` | Find files by pattern |
| `grep` | Search file contents |
| `execute` | Run shell command (sandbox only) |

### Factory

```python
from pydantic_ai_backends import create_console_toolset

toolset = create_console_toolset(
    id="console",
    include_execute=False,
    require_write_approval=False,
    require_execute_approval=True,
)
```

### Usage with pydantic-deep

The console toolset is automatically included when you create a deep agent with `include_filesystem=True` (the default):

```python
from pydantic_deep import create_deep_agent

# Console toolset is included by default
agent = create_deep_agent()

# Or explicitly disable it
agent = create_deep_agent(include_filesystem=False)
```
