SKILL: GraphQL and Hidden Parameters — Introspection, Batching, and Undocumented Fields

AI LOAD INSTRUCTION: Use this skill when GraphQL exists or when REST documentation suggests optional, deprecated, or undocumented fields. Focus on schema discovery, hidden parameter abuse, and batching as a force multiplier.

1. GRAPHQL FIRST PASS

query { __typename }
query {
  __schema {
    types { name }
  }
}

If introspection is restricted, continue with:

  • field suggestions and error-based discovery
  • known type probes like __type(name: "User")
  • JS and mobile bundle route extraction

2. HIGH-VALUE GRAPHQL TESTS

ThemeExample
IDORuser(id: "victim")
batchingarray of login or object fetch operations
hidden fieldsadmin-only fields exposed in type definitions
nested authz gapsrelated object fields with weaker checks

3. HIDDEN PARAMETER DISCOVERY

Look for:

  • fields present in admin docs but not public docs
  • additionalProperties or permissive schemas
  • frontend code using richer request bodies than visible UI controls
  • mobile endpoints carrying role, org, feature-flag, or internal filter fields

4. NEXT ROUTING
