Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned vudovn/antigravity-kit at 549ba3dc2e.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides guidance and resources for designing APIs, focusing on principles and decision-making rather than rigid patterns. It offers a curated collection of documents covering various API styles (REST, GraphQL, tRPC), response structures, versioning strategies, authentication methods, rate limiting, documentation best practices, and security considerations. The goal is to help agents make informed choices when building APIs for 2025 and beyond.

When to use it

  • When choosing between REST, GraphQL, or tRPC API styles.
  • During the design phase of a new API, ensuring proper resource naming and HTTP method usage.
  • When planning how to handle API versioning and evolution.
  • To select appropriate authentication methods (JWT, OAuth, Passkey, API Keys).
  • For guidance on structuring API responses and implementing pagination.

Key capabilities

  • API Style Decision Tree: Provides a guide for choosing between REST, GraphQL, and tRPC.
  • REST Design Guidance: Covers resource naming, HTTP methods, and status codes.
  • Response Structure Patterns: Includes information on envelope patterns, error formats, and pagination.
  • Versioning Strategies: Offers advice on URI, Header, and Query versioning approaches.
  • Authentication Options: Explores JWT, OAuth, Passkey, and API Key authentication methods.
  • Rate Limiting Techniques: Discusses Token Bucket and Sliding Window rate limiting.
  • Documentation Best Practices: Provides guidance for OpenAPI/Swagger documentation.

Example prompts

  • "What are the pros and cons of using GraphQL versus REST for this project?"
  • "How should I structure API responses to include pagination?"
  • "What are some best practices for versioning an API?"
  • "Can you give me guidance on implementing rate limiting?"

Tips & gotchas

  • Selective Reading: The skill emphasizes reading only the relevant files based on the specific context of the request. Refer to the "Content Map" within the skill's documentation to identify appropriate resources.
  • Context Matters: API design choices should be driven by user requirements and project needs, not simply following pre-defined patterns.
  • Consider Security: The skill includes guidance on security testing and addressing OWASP API Top 10 vulnerabilities.
