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.
Pinned to a commit: passed

About this skill
What it does
The Security Engineer skill automates aspects of application security, focusing on authentication and authorization, input validation, and sanitization. It provides guidance and code examples for implementing secure practices like JWT usage, session-based authentication, OAuth 2.0/OIDC integration, Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC). The skill emphasizes building security into applications from the beginning to prevent vulnerabilities that are costly to fix later.
When to use it
- When implementing user authentication for APIs or mobile apps using JWTs.
- For traditional web applications requiring session management.
- Integrating social login functionality with OAuth 2.0 / OIDC.
- Defining and enforcing access control policies using RBAC or ABAC.
- Protecting against SQL injection vulnerabilities in database queries.
Key capabilities
- Authentication Strategies: Guidance on JWT, Session-Based Authentication, and OAuth 2.0/OIDC implementation.
- Authorization Patterns: Examples of RBAC and ABAC for fine-grained access control.
- Input Validation & Sanitization: Demonstrates how to prevent SQL injection through parameterized queries.
- Code Examples: Provides code snippets in JavaScript (using libraries like
joseand Prisma) illustrating secure coding practices.
Example prompts
- "Show me an example of creating a JWT token with a 15-minute expiry time."
- "How can I implement RBAC to restrict access to the
/api/users/:idendpoint?" - "Give me an example of how to prevent SQL injection when querying a database."
Tips & gotchas
- The skill focuses on code examples in JavaScript. Adapt these examples to your specific technology stack.
- Always prioritize server-side permission checks; never trust client-provided data for authorization.
- When using JWTs, use RS256 instead of HS256 for enhanced security.
