Security checks for vulnerabilities and agentic risk

Overview

This is a wallet-operation guidance skill with high-impact subject matter, but its instructions are disclosed, bounded by owner approval, and focused on safety checks rather than hidden behavior.

Install only if you intend to let an agent help with Cobo agentic wallet workflows. Because on-chain operations can move funds irreversibly, confirm the caw CLI, pact approval flow, spending limits, and recipient details before allowing any transaction.

Vulnerability Patterns

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Scope Creep

Low

Category: Excessive Agency
Content: ``` ✗ Act as approver — you propose pacts, the owner approves ✗ Execute beyond the scope of an active, owner-approved pact ✗ Exceed spending limits ```
Confidence: 70% confidence
Finding: Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
