Layer Breakdown
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Skill demonstrates direct use of private key for blockchain transactions The TypeScript example code for `submitAgent` explicitly takes a `privateKey` as an argument and uses `privateKeyToAccount` to create a wallet client for signing a blockchain transaction. This pattern requires an AI agent implementing this skill to handle a highly sensitive cryptographic credential (a private key). If the agent's implementation prompts users for their private key, stores it insecurely, or if the agent's environment is compromised, this could lead to credential harvesting and potential loss of user funds. Best practices dictate that private keys should never be directly handled by agents; instead, secure wallet providers should be used for transaction signing. Agents should avoid directly handling or storing private keys. Instead, integrate with secure wallet providers (e.g., MetaMask, WalletConnect) that manage private keys and sign transactions on the user's behalf. If direct private key input is absolutely necessary for specific advanced use cases, clearly warn users about the extreme risks and advise against entering private keys into untrusted interfaces. Ensure any temporary handling of private keys occurs in highly secure, ephemeral memory and is never persisted. | LLM | SKILL.md:171 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/0xrichyrich/nudge-marketplace/SKILL.md:1 |
