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 entry-point-analyzer skill identifies and analyzes entry points in software, such as main functions or initialization routines. It helps users understand how a program starts execution and what components are initialized during startup.

When to use it

  • To reverse-engineer or audit the startup behavior of compiled binaries.
  • When debugging application crashes that occur early in execution.
  • During security assessments to identify potential attack vectors at runtime entry points.
  • For understanding the structure of unfamiliar codebases by examining initialization logic.

Key capabilities

  • Detection of common entry point signatures in different programming languages.
  • Analysis of control flow from initial function calls.
  • Identification of dependencies and libraries loaded during startup.

Example prompts

  • "Analyze the entry points of this compiled binary."
  • "Show me the main function and its dependencies in this application."
  • "What are the initialization routines executed when this program starts?"

Tips & gotchas

  • This skill works best with compiled binaries or disassembled code. Source code may provide more detailed insights.
  • Some obfuscation techniques can hide entry points, requiring additional analysis tools for full visibility.
