Setup & Installation
Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
What This Skill Does
Validates JSON syntax and structure by piping input through an Expanso Edge pipeline. Can run as a standalone CLI tool or as an MCP server. Supports deployment to Expanso Cloud for remote execution.
Runs as both a CLI pipeline and an MCP server, so the same validation logic works in scripts, agent workflows, and cloud deployments without changes.
When to use it
- Checking API response payloads for malformed JSON before processing
- Validating configuration files before deploying to production
- Debugging JSON parsing errors from third-party services
- Automated validation of webhook payloads in CI pipelines
- Batch-checking multiple JSON files for structural issues
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: Is this JSON valid? {"name": "Alice", "age": 30}
- 1Receives the JSON string as input
- 2Pipes it through the Expanso Edge CLI pipeline
- 3Runs syntax and structure validation
- 4Returns the validation result
Confirmation that the JSON is valid, or an error message identifying the location of the malformed content
Requirements
Accounts, API keys, or tools you or your AI assistant may need to set up while using this skill.
