TypeScript skill for OpenClaw

What this skill does

Writes, reviews, and debugs type-safe TypeScript: type errors, narrowing, generics, tsconfig strictness, and declaration files. Use when a build hits type errors ("not assignable", "possibly undefined", "excessively deep", "cannot find module"), when eliminating any or unchecked as casts, designing generics or discriminated unions, writing .d.ts files or typing untyped npm packages, configuring tsconfig or module resolution, fixing ESM/CJS import crashes ("ERR_REQUIRE_ESM", "x is not a function"), validating API or JSON data at runtime, migrating JavaScript to TypeScript or upgrading the TypeScript version, or when tsc or the editor gets slow or runs out of memory.

The TypeScript skill is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install the TypeScript skill

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for typescript and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add the TypeScript skill with a single command:

openclaw skills add typescript

This pulls typescript from ClawHub and installs it into ~/.openclaw/skills/typescript/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use the TypeScript skill

Once installed, the TypeScript skill activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download skill .zip button above to grab typescript-1.0.5.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/typescript/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
