What it does

Guide AI agents through TypeScript coding best practices including type safety, error handling, code organization, and architecture patterns. This skill should be used when generating TypeScript code, reviewing TypeScript files, creating new TypeScript modules, refactoring JavaScript to TypeScript, or when the user asks about TypeScript patterns, types, or coding standards.

Keywords: typescript, types, coding standards, best practices, type safety, generics, architecture, refactoring.

What it can touch

  • Includes 3 scripts

    Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.

    How we know

    Found in the skill’s folder: scripts/analyze.ts, scripts/generate-types.ts, scripts/scaffold-module.ts.

  • Uses terminal commands

    It shows your AI commands to run. In a coding agent that means your terminal; in a chat app it usually can’t.

    How we know

    The SKILL.md contains shell code blocks.

  • 1 smaller thing worth knowing

    Contains commands that delete or overwrite. Usually legitimate — listed so nothing is hidden.

    How we know

    Contains commands that delete or overwrite — references/architecture/project-structure.md line 351. Read 2026-10-10, commit e02ec7e.

  • No serious risk pattern found

    Launch7’s automated check read all 18 text files in this skill and matched none of its serious risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.

    How we know

    Read 2026-10-10, commit e02ec7e by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.

  • Updated this year

    Its repository has had changes recently.

    How we know

    Last push to jwynia/agent-skills: 2026-02-24 (228 days before the scan).

Read automatically from the skill’s own files on GitHub on 10 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check

Add it to your AI

Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.

  1. Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.

  2. In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.

  3. Make sure code execution is switched on (Settings → Capabilities). Skills need it.

  4. Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.

This skill ships 3 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
