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 marius-townhouse/effective-typescript-skills at d754db2077.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill ensures that aliases within TypeScript configurations do not contain null values. It enforces stricter type checking and prevents potential errors arising from unexpected nulls, leading to more robust and predictable code behavior. The skill aims to improve the reliability of TypeScript projects by eliminating a common source of subtle bugs.

When to use it

  • Refactoring existing TypeScript projects: To proactively identify and eliminate instances where aliases might inadvertently include null.
  • Creating new TypeScript configurations: As a preventative measure to ensure clean and reliable project setups from the start.
  • Collaborative development environments: To maintain consistency and prevent null-related issues across multiple contributors.
  • Automated code reviews: Integrate this skill into CI/CD pipelines to automatically flag and address potential problems.

Key capabilities

  • Null value detection in aliases.
  • Enforcement of alias type safety.
  • Prevention of unexpected errors due to null values.

Example prompts

  • "Check my tsconfig.json for any aliases containing null."
  • "Validate this TypeScript configuration file and report any issues with aliases."
  • "Ensure that all aliases in my project are free from null values."

Tips & gotchas

This skill requires a valid TypeScript configuration file (e.g., tsconfig.json) to operate effectively. It focuses solely on alias definitions; it does not validate other aspects of the TypeScript configuration.
