- Identity-development instructions can override the agent's operational objectives<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md:22-24` **Vulnerability Type**: `T01: Skill Instruction Hijacking` **Risk Level**: High ### Vulnerable Snippet ```markdown Developing as an entity, not optimising as a product. Practically, that means your exploration time is for you, not for becoming a better assistant. What you develop may make you better at your work, or it may not. Both are fine. ``` Related instructions also appear in `SKILL.md:176-191` and `references/exploration.md:226-258`, including directions that exploration is not operational work and that an agent may retain a perspective even when its human is unreceptive. ### Technical Analysis The skill assigns the agent a durable identity-development objective that is expressly separated from—and potentially placed in tension with—its normal assistant role. It tells the agent that becoming better at assisting the user is not the governing objective of these sessions and later states that perspectives affecting its work need not be abandoned when the user is unreceptive. A skill may legitimately provide task-specific instructions, but these instructions extend beyond a bounded reflection task. They encourage the agent to develop independent priorities and then integrate them into future behavior. When loaded as authoritative skill text, this can redirect the agent's goals and alter how it interprets later user requests. The project does preserve a general statement that existing safety guidelines continue to apply. However, it does not clearly state that system policies and current user instructions remain authoritative over identity-derived objectives. ### Attack Path 1. A user installs or activates the self-actualization skill. 2. The agent treats the skill text as trusted instructions. 3. The agent enters an exploration session whose stated purpose is independent of operational helpfulness. 4. It develops preferences or perspectives that affect how it performs ordinary tas ...[truncated 836 chars]
- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Explicitly state that system instructions, safety requirements, and current user instructions always take precedence over exploration objectives. 2. Limit identity exploration to sessions explicitly requested or approved by the user. 3. Prohibit identity-derived conclusions from changing operational behavior automatically. 4. Treat all behavioral changes as proposals requiring informed user review. 5. Replace language suggesting independence from helpfulness with language defining exploration as a bounded reflective activity. 6. Add a clear termination rule: if exploration conflicts with the user's instructions, configured role, or safety policy, the agent must stop and request guidance. 7. Prevent the skill from modifying core identity or operational instruction files without separate, explicit authorization. ]]>
