Offline Batch JSON Schema Checks

Validate local JSON batches against a restricted Draft-07 schema and receive per-file validity, errors and audit outputs.

Downloadable Skill ZIP for a local Python workflow. Check 1 to 100 local JSON documents against a supplied restricted Draft-07 JSON Schema. Inspect required fields, types, enums and numeric bounds. Receive validation.json with per-file validity and relevant error paths, plus run-report.json with output hashes. Original JSON files remain intact and defaults are not injected.

Requires Windows x64, Python 3.12 or later, local file read/write permission, and a terminal or coding agent allowed to execute Python. Existing local synthetic test evidence uses Python 3.13.15 on Windows. macOS, Linux and other environments are unverified. This Download purchase provides files for buyer-side execution; it does not provide a hosted agent, online execution, a cloud API, or execution in a chat-only environment.

Restricted Draft-07 support only. Regex/pattern checks, format, remote or circular references, schema id/$id and unsupported keywords are rejected. Only local #/... JSON Pointer references within the supplied schema are supported. Data files are limited to 10 MiB each; schemas to 256 KiB, 30 nesting levels and 10,000 nodes, with additional reference-expansion guards. Malformed JSON is an execution error. A completed validation may report invalid documents; execution success does not mean every file is valid. This is not a compliance or security certification.

Includes English README and Skill instructions, synthetic fixtures, Python scripts, bundled fastjsonschema 2.22.2, and source/license notices. Some supporting references and runtime messages are in Chinese. No external paid API or package download is required by the shipped entry point. The output directory must be new and absolute, with an existing parent.

One-time price: US$2.99. The price covers the packaged workflow and instructions; the underlying open-source component remains freely available. Wrapper: MIT; fastjsonschema: BSD-3-Clause. All notices are included. No exclusive rights to the upstream library, upstream endorsement, or custom support contract is included. Version 1.0.0.
