Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers and stand the test of time.
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
# API Design Principles Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers and stand the test of time. ## Use this skill when - Designing new REST or GraphQL APIs - Refactoring existing APIs for better usability - Establishing API design standards for your team - Reviewing API specifications before implementation - Migrating between API paradigms (REST to GraphQL, etc.) - Creating developer-friendly API documentation - Optimizing APIs for specific use cases (mobile, third-party integrations) ## Do not use this skill when - You only need implementation guidance for a specific framework - You are doing infrastructure-only work without API contracts - You cannot change or version public interfaces ## Instructions 1. Define consumers, use cases, and constraints. 2. Choose API style and model resources or types. 3. Specify errors, versioning, pagination, and auth strategy. 4. Validate with examples and review for consistency. Refer to `resources/implementation-playbook.md` for detailed patterns, checklists, and templates. ## Resources …

How to install
mdr add hybridlabor-api/bdb-dev-optimized-agent-skills/api-design-principles@sha256:494cebe326fff52cThe line at the top of this page pins the label git:20260827.e4036aa, 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.
