Show HN: PicoFlow - a tiny DSL-style Python library for LLM agent
workflows
Hi HN, I'm experimenting with a small Python library called
PicoFlow for building LLM agent workflows using a lightweight DSL.
I've been using tools like LangChain and CrewAI, and wanted to
explore a simpler, more function-oriented way to compose agent
logic, closer to normal Python control flow and async functions.
PicoFlow focuses on: - composing async functions with operators -
minimal core and few concepts to learn - explicit data flow through
a shared context - easy embedding into existing services A typical
flow looks like: flow = plan >> retrieve >> answer
await flow(ctx) Patterns like looping and fork/merge are also
expressed as operators rather than separate graph or config layers.
This is still early and very much a learning project. I'd really
appreciate any feedback on the DSL design, missing primitives, or
whether this style feels useful for real agent workloads. Repo:
