docs(swap): document the --refuel flag for cross-chain bridges#19
Merged
Conversation
Add the --refuel flag to the swap command reference (quote + execute), a dedicated Refuel section, the bridge workflows, and the SKILL.md validation and confirmation tables. Key caveats documented: refuel is opt-in and cross-chain only, is best-effort across aggregators, and must not be used when the destination token is the destination chain's native gas asset (the backend returns 0 quotes / NO_QUOTES in that case).

Summary
Documents the
--refuelflag for cross-chain bridges across the swap skill surface. Refuel bundles a small destination native-gas top-up into a cross-chain quote so the recipient lands with gas even when their destination native balance is zero.Pairs with the SDK/CLI support in MetaMask/agentic#204.
