// 1. search: find the tool
omnial_search({ query: "what you need" })
// 2. inspect: price and input schema
omnial_inspect({ tool: "nuget/registration-page" })
// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "nuget/registration-page" })
// 4. run: price the exact call first, then run it
omnial_execute({ tool: "nuget/registration-page", input: { /* see input_schema */ }, dry_run: true })
