Creates an Architecture Decision Record following the Nygard format to document significant technical decisions, their context, and consequences. Use when making technical choices that affect system architecture, technology selection, or development patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- PM-Skills | https://github.com/product-on-purpose/pm-skills | Apache 2.0 --> # Architecture Decision Record (ADR) An Architecture Decision Record documents a significant technical decision along with its context and consequences. ADRs capture the "why" behind architectural choices so future team members understand the reasoning - especially important when they question why something was done a particular way. This skill follows Michael Nygard's lightweight ADR format. ## When to Use - Making significant technical decisions that affect system architecture - Choosing between technology options (frameworks, databases, services) - Establishing patterns that future development should follow - Documenting the rationale for constraints or non-obvious approaches - Preserving institutional knowledge about past decisions ## When NOT to Use - The decision is a product or UX design choice, not architecture or technology -> use `develop-design-rationale` - You are still exploring whether an approach is feasible -> time-box the exploration and record it with `develop-spike-summary` first …

How to install
mdr add product-on-purpose/pm-skills/develop-adr@sha256:acab95233131e1cdThe line at the top of this page pins the label v3.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
