Automated safety checks
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.

About this skill
What it does
This skill equips AI agents with a foundational understanding of core API design principles, enabling them to evaluate and critique RESTful architectures. It helps ensure that generated interfaces prioritize clarity, consistency, and maintainability for human developers.
When to use it
- Reviewing proposed API endpoints before implementation to catch structural flaws early.
- Generating documentation that enforces standard naming conventions and resource hierarchy.
- Auditing existing codebases to identify violations of RESTful best practices like proper HTTP method usage.
- Designing stateless interactions where the agent must ensure requests are self-contained without session dependencies.
Key capabilities
- Evaluates adherence to RESTful constraints (statelessness, cacheability, uniform interface).
- Suggests improvements for endpoint naming and resource representation.
- Identifies potential security risks related to improper access control or data exposure in API definitions.
- Assists in structuring error responses and status codes according to industry standards.
Example prompts
- "Critique this REST API design for compliance with standard principles and suggest specific improvements."
- "Generate a set of API endpoints for a user management system that strictly follows RESTful conventions."
- "Explain why using POST for updating resources violates API design best practices in this context."
Tips & gotchas
Ensure the agent has access to relevant schema definitions when evaluating complex APIs, as abstract principles may not apply uniformly without context. This skill focuses on architectural patterns rather than specific implementation languages or frameworks like Django or Spring.
