Toolang v0.4 writes agent loops as functions and flows in plain-text .too files you can run from the CLI

Shown on HN, uv tool install toolang adds a runtime where an agic is a reusable agent loop with typed inputs and outputs, flow composes them in sequence, parallel lanes or loops, and skills, psyches and MCP services plug in with with lines; any .too file's agics become CLI commands with --model, --allow tools=none and token limits. It works with models.dev cloud providers plus Ollama and llama.cpp, needs Python 3.11+, and is untested on Windows.
