# JSON Repair Kit A utility to repair broken or "loose" JSON files (like those with trailing commas, single quotes, or unquoted keys) by parsing them as JavaScript objects and re-serializing as valid JSON. ## Usage ```bash # Repair a file in place (creates .bak backup) node skills/json-repair-kit/index.js --file path/to/broken.json # Repair and save to a new file node skills/json-repair-kit/index.js --file broken.json --out fixed.json # Scan directory and repair all .json files (recursive) node skills/json-repair-kit/index.js --dir config/ --recursive ``` ## Supported Repairs - **Trailing Commas**: `{"a": 1,}` -> `{"a": 1}` - **Single Quotes**: `{'a': 'b'}` -> `{"a": "b"}` - **Unquoted Keys**: `{key: "value"}` -> `{"key": "value"}` - **Comments**: Removes JS-style comments `//` (if parser supports it, standard Node `eval` may strip them if they are line comments outside of strings). - **Hex/Octal Numbers**: `0xFF` -> `255` ## Safety - **Backup**: Always creates a `.bak` file before overwriting (unless `--no-backup` is used, but default is safe). - **Validation**: Verifies the repaired content is valid JSON before writing. - **Eval Sandbox**: Uses `vm.runInNewContext` to parse, ensuring no access to global scope or process. It is safer than `eval()`.
