Live repository

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 thebushidocollective/han at 19caa51d5f.

    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 NestJS Guards and Interceptor functionality to your AI agent, enabling robust backend validation and modification of incoming requests. It allows you to implement authentication, authorization, logging, and request/response transformation within a NestJS application. The skill demonstrates how to create custom guards using CanActivate and access the ExecutionContext for contextual information during request processing.

When to use it

  • Implementing authentication checks (e.g., verifying an API key or JWT token).
  • Authorizing access to specific routes based on user roles or permissions.
  • Logging incoming requests and responses for debugging or auditing purposes.
  • Transforming request bodies or response data before processing or sending.
  • Gaining insight into the current handler and controller being executed within a NestJS application.

Key capabilities

  • Creation of custom guards implementing the CanActivate interface.
  • Access to the ExecutionContext for retrieving information about the current request.
  • Implementation of authentication patterns like JWT, session, and API key verification.
  • Method-level guard usage within controllers.
  • Logging handler and controller names during execution.

Example prompts

  • "Show me how to create a NestJS guard that checks for an authorization header."
  • "Explain how to use ExecutionContext to access the request object in a NestJS guard."
  • "Give me an example of implementing JWT authentication using a NestJS guard."

Tips & gotchas

  • Requires familiarity with NestJS concepts and TypeScript.
  • The skill provides code examples; you'll need to adapt them to your specific application logic.
  • ExecutionContext offers access to request, response, handler, and controller information – use this for context-aware validation or modification.
