## Quick Start

```python
from composio import Composio

composio = Composio(api_key="your-api-key")

# Get tools for a user
tools = composio.tools.get("user-123", toolkits=["github"])

# Execute a tool
result = composio.tools.execute(
    "GITHUB_GET_REPOS",
    arguments={"owner": "composio"},
    user_id="user-123"
)
```

## Decorators

### before_execute

[View source](https://github.com/composiohq/composio/blob/next/python/composio/core/models/_modifiers.py#L280)

```python
@before_execute(modifier: BeforeExecute | None = ..., tools: List[str | None] = ..., toolkits: List[str | None] = ...)
def my_modifier(...):
    ...
```

### after_execute

[View source](https://github.com/composiohq/composio/blob/next/python/composio/core/models/_modifiers.py#L241)

```python
@after_execute(modifier: AfterExecute | None = ..., tools: List[str | None] = ..., toolkits: List[str | None] = ...)
def my_modifier(...):
    ...
```

### before_file_upload

Build a ``Modifier`` for the file-upload hook (same scoping pattern as :func:`before_execute`).  Your callable may take **either**:  - a single ``context`` argument (:class:`BeforeFileUploadContext`) — the preferred form, exposes ``context["source"]`` (``"path"`` or ``"url"``), or - three positional arguments ``(path, tool, toolkit)`` — legacy form, kept for back-compat.  Return a new path/URL string to substitute, or ``False`` to abort the upload (raises :class:`~composio.exceptions.FileUploadAbortedError`).  Pass the returned ``Modifier`` in ``modifiers=[...]`` on :meth:`composio.core.models.tools.Tools.execute` or ``tools.get``. Multiple such modifiers are composed in list order.

```python
@before_file_upload(modifier: BeforeFileUploadLike | None = ..., tools: List[str | None] = ..., toolkits: List[str | None] = ...)
def my_modifier(...):
    ...
```

### schema_modifier

[View source](https://github.com/composiohq/composio/blob/next/python/composio/core/models/_modifiers.py#L377)

```python
@schema_modifier(modifier: SchemaModifier | None = ..., tools: List[str | None] = ..., toolkits: List[str | None] = ...)
def my_modifier(...):
    ...
```
