// Package basic implements the built-in foundation tools for Cyrene v2
// (DevDocs/design/09-插件生态.md, DevDocs/开发时间线.md M5): calculator,
// datetime, random, text, json and markdown.
//
// Each tool is an sdk.Tool that is registered through the capability registry
// via Register, and all of them are stateless values, so they are safe for
// concurrent use. The tools are pure — no I/O and no network — so they can be
// invoked from any role, any mode and any channel without sandboxing.
