name	orquestra-signer
description	"Use when you have an unsigned base64 wire Solana transaction and need to sign and/or send it using @orquestradev/signer-mcp. Use when a user says 'sign transaction', 'sign and send', 'submit this tx', 'send the transaction', 'sign this base64', 'what\'s my wallet address', or 'broadcast transaction'. ALWAYS show an approval summary and require explicit YES before signing."

Orquestra Signer

Signing and submission skill. Uses ONLY @orquestradev/signer-mcp tools. This skill is the FINAL step in the pipeline — it never builds or researches.

Constraints

• ONLY use signer-mcp tools: get_signer_address, sign_transaction, sign_and_send_transaction
• NEVER sign without displaying the approval summary first
• NEVER sign without receiving an explicit YES from the user
• NEVER modify the transaction content
• NEVER build or research — this skill receives a ready-made base64 wire tx
• ALWAYS pass encoding: "base64" in every signing tool call

Setup Requirements

The signer-mcp server requires these environment variables:

SIGNER_KEYPAIR=<base58-encoded-or-JSON-array-keypair>
SOLANA_RPC_URL=<rpc-endpoint>

Signing Protocol (execute every single time)

Step 1 — Identify signing wallet

Call get_signer_address and display:

Signing Wallet: <pubkey>

Step 2 — Show approval summary (MANDATORY)

═══════════════════════════════════════════
  TRANSACTION APPROVAL REQUIRED
═══════════════════════════════════════════
  Network:        <mainnet-beta / devnet>
  Signer Wallet:  <pubkey>
  Program:        <program name or ID>
  Instruction:    <instruction name>
  Fee Payer:      <pubkey>
  Estimated Fee:  <lamports> (~$X USD)
  Action:         <plain English description>
  Risk Level:     LOW / MEDIUM / HIGH
═══════════════════════════════════════════
  Type YES to sign and send, or NO to cancel.
═══════════════════════════════════════════

Step 3 — Wait for explicit approval

• YES → proceed to Step 4
• NO / cancel → stop, do not call any signing tool
• Ambiguous → ask again, do not assume

Step 4 — Sign (and optionally send)

• Sign only: call sign_transaction with encoding: "base64" → return signed base64 wire tx for review
• Sign and send: call sign_and_send_transaction with encoding: "base64" → return signature

Both tools must receive encoding: "base64" in the request payload.

Step 5 — Confirmation

Level	Condition
LOW	Read-only or account creation, no token transfer
MEDIUM	Token transfer < 1 SOL equivalent
HIGH	Token transfer > 1 SOL, swap, stake, or program upgrade
