JSON

What This Skill Does

The JSON skill for OpenClaw is a comprehensive toolset designed to standardize, validate, and manipulate JSON data structures within your AI agent workflows. It ensures that data interchange remains robust, secure, and predictable. This skill provides a framework for enforcing schema validation, managing strict naming conventions, handling complex data types like dates and large integers, and preventing common serialization errors such as circular references or prototype pollution. By integrating this skill, your agent gains the ability to reliably interact with external APIs, process configuration files, and generate well-formed JSON outputs that adhere to industry best practices.

Installation

You can integrate this skill into your agent environment using the ClawHub command line utility: clawhub install openclaw/skills/skills/ivangdavila/json

Use Cases

• API Integration: Automating data extraction from REST APIs while ensuring the response matches a predefined JSON Schema.
• Data Sanitization: Cleaning untrusted inputs to prevent security vulnerabilities like prototype pollution before data is processed.
• Serialization Management: Transforming complex class structures or BigInt values into valid, transportable JSON strings.
• System Configuration: Managing complex settings files where schema enforcement is necessary to prevent runtime configuration errors.

Example Prompts

1. "Validate this incoming payload against the provided user-schema and flag any missing required fields or incorrect data types."
2. "Transform this JavaScript object into a JSON-compliant string, ensuring that all BigInts are converted to strings and sensitive user email fields are stripped."
3. "Convert this list of system events into a strictly paginated JSON response format, including a next cursor and standard metadata headers."

Tips & Limitations

To get the most out of this skill, prioritize defining strict JSON Schemas with additionalProperties: false to avoid unexpected data injection. When dealing with dates, always convert to ISO 8601 strings early to maintain consistency. Be aware that this skill cannot automatically recover data lost in serialization; it relies on your explicit handling of BigInt and Map/Set structures via custom replacer functions. Always wrap JSON.parse calls in try/catch blocks, as malformed inputs are a constant risk when working with external data. Finally, remember that Unicode control characters and BOM markers at the start of files can cause silent parsing failures—sanitize your input buffers first.
