typescript-advanced-types loads a TypeScript type-system reference into Claude. It covers generics, conditional types, mapped types, template literal types and utility types, with code examples, best practices, type testing, common pitfalls and performance tips.

It triggers when you build complex type logic, reusable type utilities, type-safe API clients, form validation or typed configuration, or migrate JavaScript to TypeScript. Longer worked examples sit in references/details.md, which Claude reads when the summary is not enough. The skill bundles no scripts.

Good for

  • TypeScript developers writing library or framework types
  • Teams migrating a JavaScript codebase to TypeScript
  • Anyone building typed API clients, forms or config objects

Then check that it loaded and tell me how to use it.
  2. 2

    Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js.

The README documents both the skills installer and the plugin marketplace route. The plugin name and marketplace name come from the repo's marketplace.json. The plugin also adds 2 agents and 1 command, and 3 other skills.

Permissions

Low risk

The skill folder holds SKILL.md and references/details.md. Claude reads them as guidance; the plugin route is the only way this page's install adds agents or a command.

What it can do

  • Read your data
  • Create and change things
  • Delete things
  • Read-only mode

Watch out for

  • The plugin route adds more than this skill

    /plugin install javascript-typescript@claude-code-workflows installs the whole plugin: 4 skills, the javascript-pro and typescript-pro agents and the typescript-scaffold command. The skills installer takes this skill alone.

Questions

What does the typescript-advanced-types skill do?

It gives Claude a structured reference for TypeScript's advanced type system: generics, conditional types, mapped types, template literal types and utility types. Claude uses it when you build complex type logic or reusable type utilities.

How do I install it?

Use the install box at the top of this page. The repo's README also documents installing a single skill with the gh skill command or the skills CLI, and a Claude Code plugin marketplace route.

Does it run any code or need an API key?

No key is named in SKILL.md. The skill folder has just SKILL.md and one reference file, so it bundles no scripts.

Where do the long examples live?

In references/details.md. SKILL.md tells Claude to read that file when the summary above it is not enough.

Is it safe?

The folder holds only two markdown files and bundles no scripts. It adds guidance for Claude to follow.

Is it part of a bigger set?

Yes. It sits under the plugins/javascript-typescript folder of the wshobson/agents repo, which the README describes as a catalog of many plugins, agents and skills. You can install this one skill on its own.
