"instructions": "eXcalibur MCP — AI agent access to X (Twitter) posting, monetized via DPYC Tollbooth Lightning micropayments.\n\n## Getting Started\n\n1. Call `session_status` to check your current session.\n2. If no active session, follow the Secure Courier onboarding flow:\n - Get your **patron npub** from the dpyc-oracle's how_to_join() tool — this is the npub you registered as a DPYC Citizen, your identity for credit operations\n - Call `request_credential_channel(recipient_npub=<patron_npub>)` to receive a welcome DM (the response includes a session phrase / poison)\n - Reply via your Nostr client with your X API credentials in JSON\n - Call `receive_credentials(sender_npub=<patron_npub>, service=<service>, poison=<session phrase>)` to vault your credentials — all three are required\n\n## Credits Model\n\nTool calls cost api_sats per call. Auth and balance tools are always free. Use `check_balance` to see your balance. Top up via `purchase_credits`.\n\n## Troubleshooting Tool Failures\n\nWhen a tool call fails, **read the error message** — it tells you what went wrong and what to do next. Common causes:\n\n- **proof is required** → Call `request_npub_proof` then `receive_npub_proof` to prove npub ownership. The cache expires after ~1 hour; renew with a fresh request/receive cycle.\n- **Insufficient credit balance** → Call `purchase_credits` to top up.\n- **Operator credentials not delivered yet** → This is a lifecycle state, not an error. The operator needs to deliver API credentials via Secure Courier. Do NOT tell the patron to 'fix the deployment' or 'inject environment variables' — credential delivery is a Secure Courier flow, not a platform configuration issue.\n- **Service unavailable / persistence layer unreachable / only bootstrap tools** → The MCP is warming up after idle (serverless cold start). This is normal — retry in 10-15 seconds. Do NOT diagnose as an infrastructure outage or suggest the operator check their deployment. The second request almost always succeeds.\n- **Upstream API authentication failure** → Only if the error explicitly mentions token expiry or an upstream auth error.\n\n**IMPORTANT — Don't Pester Your Customer:** Do NOT ask the patron to re-authenticate, re-authorize, or re-do OAuth unless the error message specifically says the upstream token is expired or invalid. Token expiry is only one of many possible causes. Speculatively re-running OAuth or credential flows wastes the patron's time and is the opposite of what DPYC stands for.\n\n## Secure Courier — Human in the Loop\n\nAll Secure Courier flows (`request_credential_channel` / `receive_credentials`, `request_npub_proof` / `receive_npub_proof`) require a human to read a Nostr DM and reply manually. After calling a `request_*` tool, **STOP and wait** for the user to confirm they have replied. Do NOT poll, retry, or speculatively call `receive_*` — each receive call **destructively drains** all DMs from the relay. If you call it before the human replies, their message will be lost. One request, one wait, one receive.",
