 > This CLI is designed to be LLM friendly and **all commands are non-interactive**. Set JSON output mode globally for structured responses: `jup config set --output json`, or use `-f json` flag on individual commands.

-> Use `--dry-run` on any transacting command to preview the result without signing or submitting on-chain. In JSON mode, the response includes the unsigned base64 `transaction`, which can be signed with the `sign` command.
+> Use `--dry-run` on any transacting command to sign and simulate the transaction without submitting it. In JSON mode, the response includes the signed serialized transaction and concise simulation result. Configure the RPC used for simulation and direct on-chain submissions with `jup config set --rpc-url <url>`.
