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

The narrow-any-scope skill refines the type of an any variable to a more specific type based on subsequent usage. This allows for gradual typing and avoids the pitfalls of using any excessively in TypeScript code. It essentially helps the AI agent understand and enforce stricter types as information about the variable becomes available.

When to use it

  • When dealing with legacy JavaScript code that uses any liberally, and you want to incrementally add type safety.
  • When receiving data from an external API where the exact structure isn't known upfront but can be inferred later.
  • To improve code readability and maintainability by providing more precise type information as it becomes available.
  • In situations where a variable might initially be of unknown type, but its usage clarifies its specific type.

Key capabilities

  • Type narrowing from any to specific types.
  • Gradual typing in TypeScript projects.
  • Improved code clarity and maintainability.

Example prompts

  • "Narrow the 'data' variable which is currently any to an object with properties name: string and age: number."
  • "Refine the type of 'result' from any based on how it's used in the following lines of code."
  • "Help me narrow down this any type to a more specific interface definition."

Tips & gotchas

This skill is most effective when accompanied by clear context about how the any variable will be used. Providing relevant code snippets or data structures can significantly improve the accuracy and usefulness of the narrowed type.
