Install target

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 trailofbits/skills at 82fe822625.

    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

The CodeQL skill enables AI agents to analyze and query code using the CodeQL language, which is designed for semantic code analysis. It allows users to detect vulnerabilities, understand code structure, and perform complex queries across multiple programming languages.

When to use it

  • To identify security vulnerabilities in large codebases
  • For performing static analysis on software projects
  • When building tools that require deep understanding of code semantics

Key capabilities

  • Supports querying code in multiple programming languages
  • Enables detection of security issues and logical errors
  • Integrates with CodeQL's powerful semantic analysis engine

Example prompts

  • "Find all instances where user input is used without validation in this Python project."
  • "Analyze the JavaScript code for potential SQL injection vulnerabilities."
  • "Generate a report on code complexity across the entire C++ repository."

Tips & gotchas

  • Ensure that the CodeQL environment and dependencies are properly installed before use.
  • Query performance may vary depending on the size of the codebase and available resources.
