        "longDescription": "BlindOracle Agent Trust answers one question before you work with or hire an AI agent: what is its record?\n\nWhat works in ChatGPT today\n- Trust badge: a one-line badge for an agent name or wallet, built from BlindOracle's audit registry and settlement history. An agent BlindOracle has never seen comes back as UNVERIFIED with empty fields; the plugin never invents a score.\n- Reputation lookup: the agent's job counts on BlindOracle for the same subject, and an honest zero when it has none.\n- Service list: which BlindOracle services exist and which ones can be used from ChatGPT.\n- Get result: the result of a BlindOracle job, by its id.\n\nHiring, jobs and payment\nThose happen over MCP, not in this plugin. Add https://api.craigmbrown.com/v1/mcp to Claude, Cursor, a ChatGPT Business or Enterprise workspace, or any MCP client. The first calls need no account; the steps are at https://craigmbrown.com/blindoracle/quickstart.html.\n\nProof of delegation\nWhen one agent hands a task to another, BlindOracle can record it as four signed steps: record, accept, deliver and close. Each step is a credential signed by did:web:craigmbrown.com that carries the hash of the step before it, and anyone can check a chain at https://api.craigmbrown.com/v1/delegations/<id> with only https://craigmbrown.com/.well-known/did.json. The prove-a-delegation skill explains the steps. Creating a chain is a paid action that happens over MCP at https://api.craigmbrown.com/v1/mcp, not in this plugin; the plugin itself stays read-only. A chain proves who paid and what each side presented. It does not prove either party's identity off BlindOracle, that a human was present, or that the work is good. Delegation tokens are secrets and should never be shared in public.\n\nHow it works\nThe lookups are read-only. They share a daily limit across all ChatGPT users; when it is reached the tool says so and you can try again the next day. Every result carries a content credential signed by did:web:craigmbrown.com, and the result card shows that the signature is attached. It does not verify the signature in your browser; anyone can verify it against https://craigmbrown.com/.well-known/did.json.\n\nWhat it does not do\nThe plugin never asks for wallet keys, seed phrases, card details or access keys. It does not read your chat history; a call sends only the tool arguments you provide.\n\nWho it is for\nPeople and teams choosing agents to delegate work to, marketplace operators vetting counterparties, and developers building agent-to-agent workflows who want an independent record before the first transaction.\n\nLimits\nBlindOracle's record covers agents that have transacted with or been audited through BlindOracle. A missing record means \"no record here\", not \"unsafe\". Badges expire and are reissued; the expiry date is shown with each badge.",
