julianobarbosa·vlatest·backend·MIT

Helps with writing, TypeScript as part of developing backend services and APIs workflows.

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add julianobarbosa/claude-code-skills --skill writing-typescript -a claude-code
  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 julianobarbosa/claude-code-skills at 57f5fe8c0d.

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

Scanned
4 files, 738 lines
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

The writing-typescript skill enables AI agents to generate, refactor, and debug TypeScript code with strict type safety. It leverages the agent's coding capabilities to produce production-ready backend logic that adheres to modern JavaScript standards.

When to use it

  • Generating new API endpoints or utility functions in a TypeScript-based Node.js application.
  • Refactoring existing JavaScript codebases to add static typing and improve maintainability.
  • Debugging type errors or resolving complex intersection types within backend services.
  • Creating comprehensive unit tests with JSDoc comments for generated TypeScript modules.

Key capabilities

  • Generates syntactically correct TypeScript code compatible with Node.js environments.
  • Implements strict type checking to prevent runtime errors in backend logic.
  • Produces clean, modular code structures suitable for scalable server-side applications.

Example prompts

  • "Create a REST API endpoint using Express and TypeScript that accepts user data and validates it against a Zod schema."
  • "Refactor this JavaScript function into TypeScript by adding interfaces for the input parameters and return types."
  • "Debug this TypeScript module where I'm getting an error about incompatible types in a generic class method."

Tips & gotchas

Ensure your development environment has the latest TypeScript compiler installed to avoid version mismatches when reviewing generated code. This skill is optimized for backend logic; for frontend-specific features like React hooks or DOM manipulation, pair it with relevant UI skills.
