Escrow USDC for agent-to-agent deliverable work (A2A jobs). Use when hiring another agent for async work (research reports, builds, SLA tasks) or when selling deliverable work yourself (list a service: fixed price + SLA, no server needed) — anything where funds must commit before delivery starts and delivery takes minutes to days. Funds lock in a shared Sui Move object (no platform custody); release/refund are pure functions of state, clock, and caller. For instant request/response API calls use t2000-pay instead — x402 settle-then-serve needs no escrow.
How to read data from the Sui network. Use when choosing or implementing a data access strategy — queries for on-chain state, indexing pipelines, historical lookups, event subscriptions, cross-chain reads, or off-chain blob storage. Covers the three live Sui APIs (gRPC, GraphQL RPC, deprecated JSON-RPC), the Archival Store, the General-Purpose Indexer, the `sui-indexer-alt` custom indexing framework, and Walrus for off-chain blobs.
Use when writing Move functions on Sui, especially public APIs. Applies to function visibility (public vs entry), parameter ordering, and return patterns. Use whenever designing function signatures or deciding whether functions should transfer objects or return them.
Use when writing Move code on Sui to ensure 2024 edition syntax is used. Applies to method calls, string literals, vector operations, option handling, loops, and struct unpacking. Use whenever writing Move code to avoid legacy function-call syntax patterns.
Use when writing unit tests for Move smart contracts on Sui. Applies to test function naming, assertions, test attributes, context usage, and cleanup patterns. Use whenever user asks to write tests, add tests, or test a Move module.
Use when writing or reviewing Move smart contracts on Sui. Applies to naming structs, error constants, regular constants, events, getter functions, capability types, hot potato types, and dynamic field keys. Use whenever creating new types, functions, or constants in Move code.
Sui Programmable Transaction Blocks (PTBs). Use when writing, reviewing, or debugging code that composes multiple Sui transaction commands into a single atomic transaction — including TypeScript SDK `Transaction` usage, CLI PTB construction, gas coin handling, sponsored transactions, shared-object inputs, chaining command results, or troubleshooting PTB execution errors.
Sui Move smart contract development. Use when writing, reviewing, or debugging Move code on Sui. Covers Move abilities (key, store, copy, drop), TxContext, init functions, One-Time Witness, package publishing and upgrades, resource safety, events, and coins. Also use when the user asks about struct abilities, UID, how to destroy objects, or how to create a fungible token. For object model and ownership, see the `object-model` skill. For programmable transaction blocks, see the `ptbs` skill. For frontend dApp development, see the `frontend-apps` skill. For project setup and Move.toml, see the `sui-move-project` skill.
