--- name: jsonl-validator description: Validate JSONL files for broken lines, summarize counts, time ranges, and key distributions. Use when checking evolution logs, memory graph exports, or any line-delimited JSON data. --- # JSONL Validator Validate one JSONL file and report: - valid/invalid line counts - time range from `ts` fields, if present - top JSON keys by frequency - up to 5 invalid line examples ## Usage ```bash node skills/jsonl-validator/scripts/validate-jsonl.js <path/to/file.jsonl> ``` Exit codes: - `0` — all non-empty lines are valid JSON - `2` — invalid JSON lines found - `1` — usage or missing file error ## Notes - This skill is read-only; it does not modify files. - Large files are read fully into memory; for very large JSONL, prefer a streaming approach.
