soothe-nano 0.9.1

Soothe Nano — batteries-included Coding CoreAgent on deepagents

soothe-nano

A ready-to-run coding agent you can drop into a script or app.

Built on soothe-deepagents (filesystem, shell, subagents, skills, MCP). Nano adds the pieces you usually wire yourself: workspace safety, progressive tools/skills, research & explore subagents, and a config-driven factory.

Vision

Give builders a production-shaped coding CoreAgent in a few lines of Python.

• Start small — chat, tools, or full composition
• Stay portable — embed in notebooks, CLIs, or your own service
• Compose what you need — tools, memory, subagents, skills, and MCP via config

Features

Area	What nano provides
Tools	Builtin groups: shell, file ops, HTTP, search, data, …
Subagents	Ready: explore, plan, deep/academic research, browser
Skills / tools in context	Progressive loading — activate what the turn needs
Workspace	Scoped workspace + security defaults
Config	YAML / SootheConfig factory
Memory	Optional long-term memory via protocols
MCP	Registry and on-demand adapters

vs deepagents

	deepagents	soothe-nano
What you get	Opinionated harness	Harness plus coding product defaults
Tools	Bring your own	Builtin groups out of the box
Subagents	You define them	Ready explore / plan / research / browser
Skills / tools in context	Base support	Progressive loading
Workspace	Pluggable backends	Scoped workspace + security defaults
Config	Code-first	YAML / SootheConfig factory

Use deepagents when you want a minimal harness and full control.
Use nano when you want a coding agent that already knows how to work in a repo.

When to use nano

Scenario	Fit
Coding assistant in a repo	✅ Files, shell, explore/plan out of the box
Research / browsing agent	✅ Deep research, academic, browser subagents
Embed in your product	✅ Library API, no daemon required
Plugin / toolkit author	✅ Depends on nano only
Simple Q&A chat	✅ Strip tools/subagents as needed

Install

uv add soothe-nano

Quick start

from soothe_nano import create_nano_agent
from soothe_nano.config import SootheConfig

agent = create_nano_agent(SootheConfig())
# agent.ainvoke / streaming — see examples/

Examples live in examples/:

1. Pure model (no tools)
2. With tools
3. With memory
4. With subagents
5. Full composition
