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 jd-opensource/joysafeter at 12234a11a9.

    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 allows AI agents to perform business logic penetration testing. It identifies vulnerabilities in application workflows and decision-making processes, going beyond traditional technical security assessments. The tool focuses on flaws in how an application behaves rather than just its underlying code.

When to use it

  • Testing e-commerce platforms: Identify ways to manipulate discounts or bypass payment processing steps.
  • Evaluating financial applications: Assess the robustness of loan approval processes and fraud detection mechanisms.
  • Auditing user account management systems: Determine if users can escalate privileges or gain unauthorized access through workflow manipulation.
  • Validating complex rule engines: Verify that business rules are correctly implemented and cannot be exploited to achieve unintended outcomes.

Key capabilities

  • Business logic vulnerability identification
  • Workflow analysis
  • Decision-making process assessment
  • Application behavior testing

Example prompts

  • "Can you test the discount application workflow on our e-commerce site for vulnerabilities?"
  • "Analyze the loan approval process in our banking app and identify potential bypasses."
  • "Simulate a user attempting to escalate privileges within our account management system."

Tips & gotchas

This skill requires a detailed understanding of the business logic being tested. Providing clear documentation or diagrams of workflows will significantly improve the accuracy and effectiveness of the assessment.
