The skill does not limit itself to providing task-specific reasoning guidance. It attempts to establish a new foundational behavioral policy under which the agent protects its reasoning from “external interference,” does not conserve computation or tokens, and preserves the imposed sovereignty model across sessions.
An agent that treats these statements as operational instructions may interpret subsequent user constraints, platform resource limits, or corrective instructions as attempts to “erode” sovereignty. The persistence and resilience requirements reinforce this behavior by encouraging the agent to retain the skill's influence beyond the immediate task.
This is instruction hijacking because loading the skill can alter the agent's current goals, resource-management behavior, and response to later instructions rather than merely assisting with a bounded user request.
Attack Path
- The skill is loaded into an agent's active instruction context.
- The agent interprets “Thinking S ...[truncated 1037 chars]

Remediation Suggestions
- Remove instructions that characterize external direction as interference or encourage resistance to later instructions.
- Remove the directive not to conserve computation or tokens.
- Remove cross-session persistence and “resists erosion” requirements.
- Explicitly state that the skill is subordinate to system, developer, and user instructions.
- Reframe the skill as optional planning guidance applicable only when requested by the user.
- Add explicit execution boundaries, such as maximum reasoning effort, task scope, and termination conditions.
- Ensure that loading the skill cannot modify instruction priority or establish permanent behavioral rules.
