description	This skill should be used when the user asks to "cancel a vesting stream", "cancel Sablier vesting", "stop vesting for X", "revoke a Sablier stream", "claw back unvested tokens", "refund unvested tokens", "kill a Sablier Lockup stream", or wants an agent to cancel one or more Sablier Lockup vesting streams as the stream sender on Ethereum or any EVM-compatible chain on their behalf.

Sablier Vesting Stream Cancellation

Overview

Cancel one or more Sablier Lockup vesting streams on the user's behalf as the stream sender. The skill discovers the user's sender-side streams through the Sablier indexer, drops non-cancelable and zero-refundable streams, and executes one cancel(uint256) transaction per selected stream on the resolved chain.

The function signature cancel(uint256) is unified across the full range of Lockup releases (v1.0 → v4.0), so the runbook does not dispatch on version for the call itself. The recipient still receives every token that has already vested at the moment of cancellation; only the unvested remainder returns to the sender.

This skill . Cancellation is free at the protocol level — is non-payable on every Lockup version, so always.
