pydantic-deep

Deep agent framework built on pydantic-ai with planning, filesystem, and subagent capabilities.

Demo

See the full demo application - a complete example showing how to build a chat interface with file uploads, skills, and streaming responses.

Features

• Multiple Backends: StateBackend (in-memory), FilesystemBackend, DockerSandbox, CompositeBackend
• Rich Toolsets: TodoToolset, FilesystemToolset, SubAgentToolset, SkillsToolset
• File Uploads: Upload files for agent processing with run_with_files() or deps.upload_file()
• Skills System: Extensible skill definitions with markdown prompts
• Structured Output: Type-safe responses with Pydantic models via output_type
• Context Management: Automatic conversation summarization for long sessions
• Human-in-the-Loop: Built-in support for human confirmation workflows
• Streaming: Full streaming support for agent responses

Installation

pip install pydantic-deep

Or with uv:

uv add pydantic-deep

Optional dependencies

# Docker sandbox support
pip install pydantic-deep[sandbox]

Quick Start

import asyncio
from pydantic_deep import create_deep_agent, create_default_deps
from pydantic_deep.backends import StateBackend

async def main():
    # Create a deep agent with state backend
    backend = StateBackend()
    deps = create_default_deps(backend)
    agent = create_deep_agent()

    # Run the agent
    result = await agent.run("Help me organize my tasks", deps=deps)
    print(result.output)

asyncio.run(main())

Structured Output

Get type-safe responses with Pydantic models:

from pydantic import BaseModel
from pydantic_deep import create_deep_agent, create_default_deps

class TaskAnalysis(BaseModel):
    summary: str
    priority: str
    estimated_hours: float

agent = create_deep_agent(output_type=TaskAnalysis)
deps = create_default_deps()

result = await agent.run("Analyze this task: implement user auth", deps=deps)
print(result.output.priority)  # Type-safe access

File Uploads

Process user-uploaded files with the agent:

from pydantic_deep import create_deep_agent, DeepAgentDeps, run_with_files
from pydantic_deep.backends import StateBackend

agent = create_deep_agent()
deps = DeepAgentDeps(backend=StateBackend())

# Upload and process files
with open("sales.csv", "rb") as f:
    result = await run_with_files(
        agent,
        "Analyze this sales data and find top products",
        deps,
        files=[("sales.csv", f.read())],
    )

Or upload files directly to deps:

deps.upload_file("config.json", b'{"key": "value"}')
# File is now at /uploads/config.json and agent sees it in system prompt

Context Management

Automatically summarize long conversations to manage token limits:

from pydantic_deep import create_deep_agent
from pydantic_deep.processors import create_summarization_processor

processor = create_summarization_processor(
    trigger=("tokens", 100000),  # Summarize when reaching 100k tokens
    keep=("messages", 20),       # Keep last 20 messages
)

agent = create_deep_agent(history_processors=[processor])
