Security audit

API Documentation Builder

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent API documentation helper that does not request credentials or hide behavior, though users should review optional npm/npx tooling commands before running them.

Install is reasonable for API documentation work. Before running optional integration commands, pin package versions, use a lockfile or local project scripts, and avoid running them in an environment containing production credentials. Treat all tokens, API keys, and api.example.com URLs in the docs as placeholders.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
80% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Confidence

Finding

This markdown file documents bearer tokens, API keys, and basic auth examples, including an API key passed as a query parameter. Because the file is instructional content, it should warn readers not to place real credentials in examples and that query-parameter API keys can be exposed in logs, browser history, or caches.
