3 findings — 1 high severity, 2 medium severity. You should review these findings carefully before considering using this skill.

High

W007: Insecure credential handling detected in skill instructions

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

Insecure credential handling detected (high risk: 1.00). The prompt instructs generating and printing a private key (console.log), storing it in .env, and shows embedding API keys / Bearer tokens in HTTP requests (Authorization: Bearer {your_doppel_api_key}), which requires handling and potentially outputting secret values verbatim.

Medium

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.80). The skill explicitly fetches public, third-party data (notably the ERC-8004 subgraph via The Graph Gateway at SUBGRAPH_URL and on-chain tokenURIs/BaseScan links) and uses that returned reputation/metadata as part of its workflow to make verification and reputation-driven decisions, so untrusted user-provided content could materially influence agent behavior.

Medium

W009: Direct money access capability detected (payment gateways, crypto, banking)

What this means

The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.

Why it was flagged

Direct money access detected (high risk: 1.00). The skill explicitly instructs creating and managing a crypto wallet (generate private key, derive address, store .env), funding it with ETH, and performing onchain transactions using viem (createWalletClient, estimateGas, walletClient.writeContract). It includes code to sign/send transactions (register, setAgentURI), parse receipts, and interact with specific contract addresses on Base mainnet. These are direct crypto/blockchain wallet and transaction operations (signing/sending), which meet the "Direct Financial Execution" criteria.
