pydantic-ai-todo
Todo/task planning toolset for pydantic-ai agents
Decision gist · record as of 2026-08-14
Yes, with conditions. Install if you are building Pydantic AI agents that need task planning, hierarchical task management, or persistent multi-tenant task storage. The low install friction, active maintenance, permissive MIT license, and zero known vulnerabilities make it safe to adopt. Beta status is appropriate for a specialized toolset; verify PostgreSQL backend requirements and compatibility with your Pydantic AI version before production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; Pydantic AI agent framework must be installed and configured with a valid model provider (e.g., OpenAI API key for gpt-4.1).
- Low friction install with three runtime dependencies.
- Package is actively maintained with recent releases; last commit 2026-08-14.

What it is and what it does
pydantic-ai-todo is a task management library that plugs into Pydantic AI agents via a single-line Capabilities API. It gives agents the ability to create, read, update, and delete tasks—with optional support for subtasks, task dependencies, and automatic cycle detection. Tasks can be stored in memory (default), async memory, or PostgreSQL with multi-tenant isolation.
The package provides both a high-level Capabilities API (recommended) and a lower-level Toolset API for integration flexibility. It includes an event system for reacting to task state changes via webhooks and callbacks. Storage backends are pluggable, and the system prompt can be static (for LLM prompt caching) or dynamic (embedding live task lists). Runtime dependencies are pydantic-ai-slim, pydantic, and redis.
Use it for
- Enable an AI agent to plan and track subtasks for a complex project, with automatic dependency resolution and cycle detection.
- Build a multi-tenant task management system where different users' agents maintain isolated task lists in PostgreSQL.
- Integrate task completion events with external webhooks to trigger notifications or downstream workflows when agent-created tasks change state.
- Use in-memory task storage for lightweight agent-driven planning in development or single-session scenarios without database setup.
- Combine with Pydantic AI's YAML agent definitions to declaratively enable task planning in agent configurations.
