python-api-design from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/python-api-design@git:20261103.8277e03Pins git:20261103.8277e03 in mdr.lock. Pin the fingerprint instead.

Use when designing or reviewing Python public APIs and compatibility, schema evolution, static-checker coverage, generic type contracts, Protocol/ABC boundaries, TypedDict schemas, dataclass invariants, dependency injection, or SOLID and design patterns: factories, builders, adapters, decorators, state machines, shallow immutability, cooperative MRO, and descriptors.
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
# Python API Design ## Route by decision | Need | Default / reference | |---|---| | Public exports, changed defaults, deprecation, HTTP/schema compatibility | Review actual consumers and generated contracts — [Evolution and public surface](references/evolution.md) | | Public types, generics, Protocol/ABC, external schemas | Concrete signatures; validate separately — [Typing contracts](references/typing-contracts.md), including the validated `ByteRange` example | | Establish or repair type-checking coverage; distribute typed libraries | Reuse the project's checker and verify downstream types — [Checker operations](references/checker-operations.md) | | Constructor, singleton, factory, builder, prototype, pool | Direct construction and explicit resource owner — [Creation](references/creational.md) | | Adapter, bridge, composite, decorator, facade, flyweight, proxy | Explicit composition — [Composition](references/structural.md) | | Chain, command, iterator, mediator, memento, observer, state, strategy, template, visitor | Ordinary control flow and owned state — [Behavior](references/behavioral.md) | …

How to install
mdr add lu1sdv/skillsmd/python-api-design@sha256:0f830e2b5d0388deThe line at the top of this page pins the label git:20261103.8277e03, 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.
