A simple utility to recursively scan the workspace for .json files and validate their syntax using JSON.parse().

Usage

# Scan the entire workspace (from current working directory)
node skills/json-linter/index.js

# Scan a specific directory
node skills/json-linter/index.js --dir path/to/dir

Output

JSON report containing:

scanned_at: Timestamp
total_files: Number of .json files scanned
valid_files: Number of valid files
invalid_files: Number of invalid files
errors: Array of error objects:
- path: Relative path to file
- error: Error message (e.g., "Unexpected token } in JSON at position 42")

Example Output

  "scanned_at": "2026-02-14T21:45:00.000Z",
  "total_files": 150,
  "valid_files": 149,
  "invalid_files": 1,
  "errors": [
