dna-sdk (Python)
Python SDK for DNA — Domain Notation of Anything: a microkernel + extensions runtime for declarative agent notation. See the repository README for the thesis, the architecture and the full Kind catalog.
Install
pip install dna-sdk # or: uv add dna-sdk
Pre-release / exact-pin alternative — from the repo:
cd packages/sdk-py
uv sync # or: pip install -e .
Optional extras: postgres, sqlite, sql (SqlAlchemySource — one
adapter for both SQL dialects, same tables; see docs/PORT-CONTRACT.md
§ "Using the SQLAlchemy adapter")
safety-ml (PII/toxicity models),
all, dev.
Minimal example
from dna import Kernel
# Scan a scope (directory of YAML/Markdown manifests under .dna/)
mi = Kernel.quick("hello-genome", base_dir="examples/hello-genome/.dna")
# Every document is identified by (apiVersion, kind, name)
for d in mi.documents:
print(d.api_version, d.kind, d.name)
# Compose agent + soul + skills + guardrails into one system prompt
print(mi.build_prompt(agent="greeter"))
Runnable version: examples/hello-genome/run.py.
