Use cases
Build production-grade tool-using assistants
Engineers can compose agents with pluggable tools, typed schemas, and memory modules to create reliable assistants that go beyond demos and run in production environments.
Design custom multi-step agent pipelines
Developers can chain composable building blocks into multi-step workflows, swapping components like LLM providers or tools without rewriting surrounding code.
Prototype provider-agnostic AI workflows
Teams can experiment with different LLM providers behind a consistent interface, making it easy to compare models or switch vendors as requirements evolve.
Create testable, maintainable agent systems
Python teams that prioritize type safety and predictability can build agentic systems with clear interfaces, making each component straightforward to unit test and maintain.

- Strong typing improves reliability
- Good fit for production use cases
Cons
- Requires Python development skills
- Less plug-and-play than higher-level platforms
- Smaller ecosystem than larger frameworks

Solid for our team
We rolled this out across the team last quarter and good fit for production use cases. Composable agent building blocks fits neatly into how we already work, and pluggable tools and memory modules removed a step we used to do by hand. Less plug-and-play than higher-level platforms, which is the main caveat, but it has held up under daily use.
Does the job
Pretty happy overall. Pluggable tools and memory modules just works and minimal, transparent abstractions. Less plug-and-play than higher-level platforms can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space
I've evaluated a lot of these over the years. What stands out here is composable agent building blocks — handled better than most — and modular components are easy to swap. Requires Python development skills is my one real gripe. Worth the time if this is your use case.
