vara-eth-skills

Build and verify Vara.eth deploy, interaction, and integration examples after a contract already exists. Use when an AI agent is asked to upload or create a program, initialize it, fund executable balance, send messages, read state, handle replies, use `ethexe` CLI, script flows with `@vara-eth/api`, or create/interact through a Solidity ABI interface.

Write and review Rust Sails contracts for Vara.eth. Use when an AI agent is asked to scaffold a new contract with `cargo sails new --eth`, implement or explain `Program` and `Service` structure, add events and exported methods, define payable methods, choose ABI-safe public types, or flag `ethexe` runtime limitations and forbidden patterns in contract design.

Build and verify complete user-facing Vara.eth applications. Use when Codex is asked to create, organize, repair, or review a full app or dApp that spans Rust/Sails contracts, Vara.eth deploy or attach flows, TypeScript interaction modules, wallet-based frontend UX, ABI-enabled calls, Solidity adapters, environment configuration, scripts, and end-to-end validation.

Build, repair, deploy, activate, or review Vara.eth apps that use injected transactions for writes and Vara.eth RPC state reads. Use when Codex is asked to make a browser/frontend dApp where MetaMask or another EIP-1193 wallet signs an injected Vara.eth transaction, when configuring `createInjectedTransaction`, when preparing an existing Rust/Sails program for injected frontend use, or when measuring injected transaction latency/cost through executable balance reads.

Build, repair, or review browser frontends that interact with a Solidity adapter contract whose backend is an ABI-enabled Vara.eth Mirror/Program. Use when user writes go through normal Ethereum wallet transactions to an adapter, the adapter calls Vara.eth asynchronously, callbacks finalize adapter state, and the frontend must read both adapter state through Ethereum RPC and optional Vara.eth state through Vara.eth RPC.

Design and review Solidity contracts that integrate with Vara.eth programs through generated Solidity ABI interfaces. Use when an AI agent is asked to build an Ethereum-side adapter, escrow, bridge-like flow, callback handler, or Solidity contract that calls a Vara.eth Mirror/ABI contract and processes async replies.
