sablier-cancel-vesting

sablier-cancel-vesting is a skill for Claude Code from sablier-labs/sablier-skills. It costs 108 tokens per session (1,815 once invoked), scanned A, original, MIT.

A procedure for cancelling Sablier Lockup vesting streams, which are blockchain arrangements that release tokens to a recipient over time. It returns the unvested portion to the sender while leaving already vested tokens with the recipient.

In plain words
What is it for?
Finding eligible Sablier streams on one EVM blockchain, cancelling selected streams, and recovering their unvested tokens.
Why use it?
It identifies which sender-owned streams can be cancelled and handles the required blockchain transactions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sablier-cancel-vesting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/filter-cancelable.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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 charges no markup. Cancellation is free at the protocol level — cancel(uint256) is non-payable on every Lockup version, so MSG_VALUE = 0 always.

This skill is a coordinator for vesting cancellation and execution routing.

Arguments

Argument Description
chain_name EVM chain where the streams live (e.g. "Ethereum", "Base", "Polygon"). One chain per invocation.
wallet_address The user's wallet. Must be the streams' sender — only senders can call cancel. The skill never surfaces streams where the wallet is not the sender.
token_symbol Token symbol to narrow the search (e.g. "USDC", "SABL"). If omitted, every token the wallet has an active sender-side stream in is shown.

Workflow

1. Confirm product fit

  1. Verify the user wants to cancel existing Sablier vesting streams as the sender.

  2. If the user wants to create a vesting stream instead, route to sablier-create-vesting. If that skill is unavailable, recommend installing it with:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
