# Tool Schemas Reference Integrity Map

Inspects declared tool-schema inheritance links to detect missing nodes, cycles, and cross-owner references without resolving external dependencies.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tool-schemas-reference-integrity-map-762651e6 -d '<json body>'
```

Example prompt: Can you check these 5 tool schema contracts for missing nodes, inheritance cycles, or cross-owner reference links? They're public non-personal metadata and I need to know if any declarations have broken or circular inheritance.

## When to prefer this

Choose this endpoint when you need a fast, offline structural integrity check of tool-schema inheritance declarations — specifically to catch missing nodes, cycles, and cross-owner links — without needing full JSON Schema or MCP validation. It is ideal for pre-deployment audits of non-personal, public or synthetic schema metadata where external reference resolution is not required.

## Known failure modes

- Input array exceeds 32 contracts — request rejected
- nonpersonalMetadata not set to true — validation fails
- dataClass not one of 'public' or 'synthetic' — enum validation error
- No contracts provided (minItems:1 violated) — bad request
- Malformed contract objects in array — schema parse error

## How this service works

Inspect declared tool-schema declaration inheritance links for missing nodes, cycles and cross-owner links. No external references are resolved; this is not complete JSON Schema or MCP validation. Offline typed nonpersonal metadata only. Result retention: 24 hours; minimal receipt metadata: 90 days.

## Output

A structured report identifying: missing referenced nodes in the schema inheritance graph, detected cycles in declaration links, and cross-owner reference links. Results are scoped to the submitted contracts with no external resolution. Results are retained for 24 hours; minimal receipt metadata for 90 days.
