// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "omnial/stablecoins" })

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

// 5. settle: the call is charged when it finishes, nothing to do
