API Design Principles
SkillMediaapi-design-principles is a skill that teaches an AI agent REST and GraphQL API design principles. When you ask it to design claude skill APIs or any other API, the agent applies established best practices so the resulting interfaces are intuitive, scalable, and maintainable.
Available today. Use it from your connected AI after setup.
No other account needed.
Have an AI agent that supports loading skills.
Then ask your AI: use the API Design Principles skill
What your AI can do with it
- Applies REST design best practices when the agent designs an API
- Applies GraphQL design best practices
- Guides the agent toward intuitive API interfaces
- Helps produce scalable API designs
- Helps produce maintainable API designs
Getting started
- Have an AI agent that supports loading skills.
- Add the api-design-principles skill to the agent's available skills.
- Ask the agent to design an API; it will apply REST and GraphQL design principles to the task.
What this skill tells your AI
The instructions your AI receives, as published by davila7/claude-code-templates in cli-tool/components/skills/development/api-design-principles/SKILL.md and read by ahel’s review.
Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs that delight developers and stand the test of time.
