Data Validation skill for OpenClaw

What this skill does

Validate data with schemas across languages and formats. Use when defining JSON Schema, using Zod (TypeScript) or Pydantic (Python), validating API request/response shapes, checking CSV/JSON data integrity, or setting up data contracts between services.

The Data Validation skill is part of the Data & APIs category — data and API skills that fetch, query, and work with external data sources. You can install it on its own or alongside other data & apis skills from the OpenClaw catalog.

How to install the Data Validation 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 data-validation 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 Data Validation skill with a single command:

openclaw skills add data-validation

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

How to use the Data Validation skill

Once installed, the Data Validation 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 data-validation-1.0.0.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/data-validation/ (create the directory if it does not exist).
