# Transactions (/docs/tx) Every mutation is an **intent**: preview it with `plan` / `--dry-run`, submit it with `execute`. Each CLI command below is `btcli tx `; each Python class is `sub.`. The machine-readable catalog of all of these (with JSON schemas) is at [`/catalog/intents.json`](/catalog/intents.json) or via `btcli tools` / `sub.intents.list_tools()`. ## AdminUtils [#adminutils] |
