ConcernMedium Confidence
ASI02: Tool Misuse and Exploitation
What this means

If the API key is available, an agent could potentially initiate wallet operations through the remote API, including financially significant actions.

Why it was flagged

The skill delegates direct API use to the agent for a financial service. In the visible artifacts, this is not paired with mandatory confirmation, spending limits, or scoped safe workflows for high-impact actions.

Skill content
This skill is **doc-only**. There is no local CLI. Agents must call the Sponge Wallet REST API directly.
Recommendation

Only use this skill if you understand the API permissions and can enforce explicit user confirmation, spending caps, allowlists, and review before transfers, swaps, purchases, or trades.

ConcernMedium Confidence
ASI03: Identity and Privilege Abuse
What this means

The agent may obtain persistent wallet API authority before the human owner has completed account claiming or approval.

Why it was flagged

For a wallet service, returning a live API key to the agent before human claim or approval is high-impact credential delegation. The visible instructions even label this mode as recommended.

Skill content
**Agent-first** (`agentFirst: true`): agent receives the API key immediately, and the human can claim later.
Recommendation

Prefer the standard device flow where a human approves before the API key is issued, and avoid agent-first mode unless the wallet is testnet-only or tightly funded and allowlisted.

What this means

A user may install the skill expecting wallet balance and transfer management, without realizing it can also support purchases, auto-payments, and market trading.

Why it was flagged

The short description frames the skill as wallet management, but the visible endpoint list also includes automatic payments, prediction-market trading, and Amazon purchasing.

Skill content
description: Manage crypto wallets, transfers, swaps, and balances via the Sponge Wallet API. ... POST /api/x402/fetch -> x402 fetch (auto-pay 402s) ... POST /api/polymarket -> Polymarket prediction market trading ... POST /api/checkout -> Amazon checkout (initiate purchase)
Recommendation

Update the description and user-facing guidance to clearly disclose all purchase, trading, and auto-payment capabilities before installation.
