JSON

Description

Parses, validates, transforms, and designs JSON payloads that survive real parsers, real clients, and real data sizes. Use when a parse fails at a byte offset or on a trailing comma, an id or an amount loses precision, accents and emoji come back as mojibake, a field is null when it should be absent, duplicate keys silently win, a JSON Schema passes what it should reject or a `$ref` will not resolve, a multi-gigabyte file will not fit in memory, a jq, JMESPath, or JSONPath expression returns nothing, two documents must be diffed or patched, a webhook signature fails after the body was re-serialized, untrusted input must be parsed safely, or a response shape has to change without breaking existing clients. Covers NDJSON, JSON Patch, canonical form, JSON columns in SQL, and JSON5/JSONC config files. Not for constraining LLM output (`structured-output`), for YAML, TOML, XML, or CSV (their own skills), or for designing REST endpoints (`rest-api`).
