"""Contributed utilities for specific agent styles.

This package contains domain-specific tools and optimizers that extend
the core primitives. These are useful batteries for building agents but
are not part of the minimal core library.

Subpackages:

- ``contrib.mailbox``: Redis-backed mailbox implementation
- ``contrib.optimizers``: Workspace digest optimizer
- ``contrib.tools``: Planning tools, VFS, Podman sandbox, asteval, workspace digest

Example usage::

    from weakincentives.contrib.tools import (
        PlanningToolsSection,
        VfsToolsSection,
        AstevalSection,
        PodmanSandboxSection,
    )

    from weakincentives.contrib.mailbox import RedisMailbox
