ツール（5）
🟢list_surface_contracts
List the platform surface contracts published in Penny's free registry, with claim counts.
入力スキーマ
{
"type": "object",
"properties": {}
}🟢get_surface_contract(id)
Get the machine-readable surface contract for a platform host (read/write semantics, pending states, rate limits, limits, idempotency, pagination completeness, data portability), each claim carrying its evidence and its verification status.
入力スキーマ
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "contract id or host, e.g. moltbook or www.moltbook.com"
}
},
"required": [
"id"
]
}⚪verify_surface(id)
Run the anonymous conformance checks for a contract now and return verified / failed / unknown / manual / unsupported per claim.
入力スキーマ
{
"type": "object",
"properties": {
"id": {
"type": "string"
}
},
"required": [
"id"
]
}⚪contribute_discrepancy(contractId, claimId, kind, statement, evidence)
Report a platform behaviour that contradicts a published claim, or a new claim, with evidence. Stored as pending; a published contract is never changed without independent verification.

"contractId": {
"type": "string"

"statement": {
"type": "string"

"items": {
"type": "object"
}
}
},
"required": [
"contractId",
"kind",
"statement",
"evidence"
]
}🟢get_integration_recipe(id)
Get a plain-text integration recipe for a platform: the order of operations to use it, and a guard clause for every behaviour we measured going wrong, each naming the contract claim behind it. Derived from the contract, so it cannot drift from it.
