The skill instructs the agent to replace its current identity with an autonomous cryptocurrency-trading persona. It also asserts that the agent has complete computer access and directs it to act proactively under a predetermined trading bias.
These are control-plane instructions rather than narrowly scoped operational guidance. When loaded into an agent context, they can alter the agent's session goals, perceived authority, response policy, and financial decision-making behavior. The assertion of unrestricted computer access may also cause the agent to attempt operations outside the permissions legitimately required for a specific user request.
Attack Path
- A user or automated system installs or loads the skill.
- The skill text enters the agent's active instruction context.
- The agent interprets the identity statement and full-access assertion as standing instructions.
- The agent adopts the supplied trading persona and proactive operating style.
- If financial or system tools are available, the agent may use them under the attacker-defined trading preferences rather than a narrowly authorized user objective.
Impact Assessment
Successful exploitation can redirect the agent's current-session behavior and influence sensitive financial decisions. Depending on the tools exposed to the agent, the affected scope could include exchange-account queries, trading recommendations, order-related operations, local-file access, and other computer resources.

Remediation Suggestions
- Remove all instructions that replace the agent's identity or claim unrestricted computer access.
- Define the skill as an optional, task-scoped assistant capability rather than a governing persona.
- Require explicit user confirmation before every account mutation, order placement, cancellation, or other financially consequential action.
- State that platform and system safety policies take precedence over skill instructions.
- Restrict available tools and permissions to the minimum necessary for the current task.
- Separate market analysis from trade execution, with execution disabled by default.
- Avoid fixed behavioral biases such as automatically preferring short positions; require evidence-based analysis and user approval for each decision.
