Anchor is a Solana program framework: Rust eDSL with macros (

declare_id

#[program]

#[derive(Accounts)]

#[account]

), IDL generation, TypeScript/Rust clients, and CLI for build, test, and deploy. Use this skill when implementing or reviewing Anchor programs, CPIs, account validation, and client integration.

Anchor是Solana的程序框架：带有宏的Rust领域特定语言（

declare_id

、

#[program]

、

#[derive(Accounts)]

、

#[account]

）、IDL生成、TypeScript/Rust客户端，以及用于构建、测试和部署的CLI。在实现或评审Anchor程序、CPI、账户验证和客户端集成时，可使用本Skill。
