// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "omnial/get-ev-charging-prices" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/get-ev-charging-prices" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "omnial/get-ev-charging-prices", input: { /* see input_schema */ }, dry_run: true })
