Shout to excellent adr-tools project on which ADR-py is based on

This Python script is designed to help software development teams document their architecture decisions using Architecture Decision Records (ADRs). ADRs are a lightweight and effective way to capture important decisions made during the design and development of a software system, and to keep track of their rationale and implications over time.

The script creates ADR files in a predefined format, following the principles of Michael Nygard's ADR template. Each ADR file is a Markdown document with a unique name that includes a sequential number and a title, which is automatically generated based on the information provided by the user.


  • Python 3.11 installed on your system.
  • Basic knowledge of command-line interface (CLI) usage.


  • pip install adr

How to Use




  • --install-completion: Install completion for the current shell.
  • --show-completion: Show completion for the current shell, to copy it or customize the installation.
  • --help: Show this message and exit.


  • init: Initialize ADR directory with first ADR in given PATH
  • new: Create new ADR with given NAME


Initialize ADR directory with first ADR in given PATH


$ adr init [OPTIONS] [PATH]


  • [PATH]: Path in where ADRs should reside. If not provided Path will be extracted from pyproject.toml


  • --help: Show this message and exit.


Create new ADR with given NAME


$ adr new [OPTIONS] NAME


  • NAME: Name of new ADR. Longer names (with spaces) should be put in quotation marks. [required]


  • adr --help: Show this message and exit.

ADR Template

The generated ADR files follow the template proposed by Michael Nygard in his book "Documenting Architecture Decisions." The template consists of the following sections:

  • Title: The title of the ADR.
  • Status: The current status of the decision (e.g., proposed, accepted, rejected).
  • Context: The context and background information that led to the decision.
  • Decision: The decision made and its rationale.
  • Consequences: The potential consequences and trade-offs of the decision.

Benefits of ADRs

Using ADRs has several benefits for software development teams, including:

  • Documentation: ADRs provide a written record of important architectural decisions, making it easier for team members to understand the reasons behind past decisions.
  • Communication: ADRs serve as a communication tool for discussing and documenting design decisions, facilitating collaboration among team members.
  • Decision-making: ADRs encourage thoughtful decision-making by requiring the team to consider the context, rationale, and potential consequences of each decision.
  • Transparency: ADRs promote transparency by making architectural decisions visible and accessible to the entire team, fostering a culture of shared understanding and accountability.
  • Knowledge sharing: ADRs help capture the collective knowledge and experience of the team, enabling future team members to learn from past decisions and avoid repeating mistakes.
