name: settlement-witness description: "OpenClaw skill: fetch replay-stable PASS/FAIL receipts from the public SettlementWitness HTTPS endpoint. Stateless. Deterministic. Signed."

SettlementWitness (OpenClaw Skill)

This skill calls the public SettlementWitness HTTPS endpoint. No local services are required.

What this skill does

When a task is complete and you need proof-of-delivery before settlement, call SettlementWitness to obtain a replay-stable receipt.

SettlementWitness does not judge quality or arbitrate disputes. It only checks whether the provided output matches the provided spec under deterministic rules.

Canonical endpoints

• POST https://defaultverifier.com/settlement-witness
• GET https://defaultverifier.com/manifest

Required input shape

Provide:

• task_id (string)
• spec (object)
• output (object)

Example request

{ "task_id": "example-002", "spec": { "expected": "foo" }, "output": { "expected": "foo" } }

How to interpret

• If verifier_response.verdict == PASS: verified completion
• If verifier_response.verdict == FAIL: not verified (do not settle automatically)
• receipt_id is the stable identifier to store/log/share

Safety notes

• Never send secrets (private keys, API keys) in spec/output.
• Keep spec/output minimal and deterministic (hashes/IDs are ideal).
