Checked
jwynia·vlatest·backend

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

Repository

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 jwynia/agent-skills --skill typescript-best-practices --full-depth -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 jwynia/agent-skills at e02ec7e226.

    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

The TypeScript best practices skill enforces strict coding standards and architectural patterns to ensure robust, maintainable backend codebases. It automatically applies linting rules, type safety checks, and design principles common in professional TypeScript development environments.

When to use it

  • Refactoring legacy JavaScript codebases to enforce strong typing and reduce runtime errors.
  • Standardizing team workflows by applying consistent naming conventions and file structures.
  • Preparing code for production deployment by validating against industry-standard security and performance guidelines.
  • Generating boilerplate code that adheres to specific project architecture requirements from the start.

Key capabilities

  • Applies comprehensive ESLint configurations tailored for TypeScript projects.
  • Enforces strict type checking to catch errors during development rather than runtime.
  • Implements design patterns like Dependency Injection and Repository patterns automatically.
  • Generates unit test scaffolds with proper type coverage.
  • Configures build pipelines for optimal bundling and tree-shaking.

Example prompts

"Refactor this function to use TypeScript interfaces and add JSDoc comments explaining the logic." "Set up a new project structure following enterprise-grade TypeScript best practices with separate modules." "Analyze this codebase and suggest improvements based on common TypeScript anti-patterns."

Tips & gotchas

Ensure your development environment has the latest TypeScript compiler installed to avoid compatibility issues with modern syntax features. This skill works best when integrated early in the development lifecycle rather than applied as a post-hoc fix to large, untyped systems.
