What problem does it solve? Working with the Sui CLI involves many command groups, subtle syntax rules (like @ prefixes on object IDs in PTBs), and evolving flags that are easy to get wrong, leading to failed transactions, misconfigured environments, or unsafe key handling. ## Core Features & Use Cases - PTB Transaction Construction: Build Programmable Transaction Blocks with correct quoting, variable assignment, gas budgeting, and dry-run/preview workflows instead of legacy pay/transfer commands. - Move Package Lifecycle: Scaffold, build, test, publish, and upgrade Move packages, including ephemeral test-publish flows and UpgradeCap routing. - Keys, Replay, and Validators: Manage keystores with Bech32 suiprivkey strings, hardware signers via sui external-keys, replay transactions with traces, and run validator operations. - Use Case: You need to publish a Move package to testnet and transfer the resulting UpgradeCap to your address. The Skill provides the exact PTB command sequence with proper gas budget and sender resolution. ## Quick Start Ask the assistant to show you how to transfer 1 SUI to another address using a Sui Programmable Transaction Block.
