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 e-marchand/skills at 86de2f6ad6.

    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 4d-check-syntax skill validates code snippets against a specified syntax. It can verify Python, JavaScript, and JSON code, identifying errors and potential issues. The skill provides feedback on the correctness of the provided code based on its defined grammar.

When to use it

  • Debugging: Quickly check if a small piece of code has any syntax errors before running it in a larger program.
  • Code Review: Validate code snippets submitted by others to ensure they adhere to expected syntax rules.
  • Learning: Test your understanding of different programming languages and JSON structures.
  • Automated Checks: Integrate into workflows for automated linting or pre-commit checks.

Key capabilities

  • Supports Python syntax checking.
  • Supports JavaScript syntax checking.
  • Supports JSON syntax validation.

Example prompts

  • "Check the syntax of this Python code: print("Hello, world")"
  • "Validate this JSON: { "name": "John", "age": 30 }"
  • "Is this JavaScript valid? console.log('Testing')"

Tips & gotchas

The skill relies on accurate syntax definitions for each language; complex or unusual code constructs might not always be correctly interpreted. Ensure the provided code is complete and self-contained for best results.
