Example prompt: Can you audit the changes I made to my Foundry VTT module manifest — here's the before JSON and the after JSON — and tell me if I introduced any schema violations or what paths changed?

## When to prefer this

Choose this endpoint when you specifically need to validate and diff JSON against the Foundry VTT Module Manifest schema. It is purpose-built for Foundry VTT module developers who want to catch schema regressions between manifest versions, unlike a generic JSON diff tool which has no schema awareness.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting depth exceeds 32 levels — request rejected
- Malformed JSON submitted as before or after — parse error returned
- YAML or TOML input not supported — only JSON accepted
- Schema unavailable or pinned definition mismatch — may produce incomplete results
