python-development skillB

python-development is agent-read markdown (skill) from d-padmanabhan/agent-engineering-handbook: Python development standards for code review and generation. Covers Python 3.14+ patterns including template strings (t-strings), deferred annotations, free-threading, type hints, async/await, testing with pytest, package management with uv, AWS Lambda/boto3 patterns, and Pydantic validation. Use when working with .py files, pyproject.toml, requirements.txt, Lambda functions, or when asking about Python best practices, code review, or generation..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add d-padmanabhan/agent-engineering-handbook/python-development@git:20260906.0766fec
Exact content
mdr add d-padmanabhan/agent-engineering-handbook/python-development@sha256:0fea08edf97605d8

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
