 ## Pre-flight Checks
 
 Before executing any write command, verify:
 
-1. **Binary installed**: `pancakeswap --version` — if not found, install the plugin via the OKX plugin store
-2. **Wallet connected**: `onchainos wallet status` — confirm wallet is logged in and active address is set
+1. **Binary installed**: `pancakeswap --version` — if not found, run the install script above
+2. **Wallet connected**: `onchainos wallet addresses` — confirm wallet is logged in and active address is set
 3. **Chain supported**: target chain must be BNB Chain (56), Base (8453), or Arbitrum (42161)
 
 If the wallet is not connected, output:
