mark-json-audit

Send any JSON text — get back a structured report: validation result, issues list (empty objects/arrays, null values, mixed types, oversized nodes, whitespace keys) with JSON-path locations; metrics (depth, node count, root type, byte size); and a verdict. Pure Python — no LLM, no network, deterministic. Input: JSON string or JSON {"json": "..."}. Great for CI pipelines, config audits, and API response inspection.
