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 giuseppe-trisciuoglio/developer-kit at fe73fb33a0.

    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 helps AI agents identify and test boundary conditions in software code. It focuses on edge cases such as minimum, maximum, or out-of-range inputs to ensure robustness and reliability of functions.

When to use it

  • Testing a function that handles numerical ranges (e.g., validating user input within specific limits).
  • Ensuring a system behaves correctly when receiving unexpected or extreme values.
  • Preparing for code reviews by identifying potential edge cases that may not be covered in existing test suites.

Key capabilities

  • Detects boundary conditions such as minimum and maximum values.
  • Generates test cases for edge scenarios like empty inputs, null values, or overflow/underflow situations.
  • Analyzes function parameters to determine valid ranges and constraints.

Example prompts

  • "Generate unit tests for the calculateDiscount function that checks behavior when the discount percentage is 0% or 100%."
  • "Identify boundary conditions in the validateEmail function, including empty strings and invalid formats."
  • "Test edge cases for a function that processes user age input, such as negative numbers or values above 120."

Tips & gotchas

  • Ensure the code being tested has clear constraints defined (e.g., input ranges) to get accurate results.
  • This skill works best with well-documented functions; ambiguous logic may lead to incomplete test coverage.
