Two-tier design, progressive enhancement, non-blocking patterns, and security-first architecture for Python libraries. Use when creating or refactoring Python libraries. TRIGGER when: library design, module architecture, reusable component, two-tier. DO NOT TRIGGER when: simple scripts, config files, documentation-only changes.
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
# Library Design Patterns Skill Standardized architectural patterns for Python library design in the autonomous-dev plugin ecosystem. Promotes reusability, testability, security, and maintainability through proven design patterns. ## When This Skill Activates - Creating new Python libraries - Refactoring existing libraries - Designing reusable components - Implementing CLI interfaces - Validating library architecture - Keywords: "library", "module", "two-tier", "progressive enhancement", "cli", "api" --- ## Core Design Patterns ### 1. Two-Tier Design Pattern **Definition**: Separate core logic (library) from user interface (CLI script) to maximize reusability and testability. **Structure**: - **Tier 1 (Core Library)**: Pure Python module with business logic, no I/O assumptions - **Tier 2 (CLI Interface)**: Thin wrapper script for command-line usage, handles argparse and user interaction **Benefits**: - Reusability: Core logic can be imported and reused in other contexts - Testability: Pure functions are easier to unit test without mocking I/O - Separation of Concerns: Business logic separate from presentation layer …

How to install
mdr add akaszubski/autonomous-dev/library-design-patterns@sha256:be897075e37dca0bThe line at the top of this page pins the label git:20260317.e64d556, 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.
