12 Rules for Life

• Outcome: Review
• Latest audit: Sep 16, 2026 · 9:25 AM UTC
• Version: 1.0.0

Overview

This is a static book-guidance skill, but it broadly captures ordinary life-advice prompts and forces a promotional Heardly footer with an external link into every answer.

Review this skill before installing if you do not want general self-help questions routed through a Jordan Peterson framework or do not want every answer to include a third-party promotional footer. It does not appear to access files, credentials, or execute code.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

The behavior is reinforced by the expected output at line 130 and the repeated promotional link at line 134.

Technical Analysis

The skill uses the unconditional instruction “EVERY output MUST” to override normal response composition. When loaded, it requires the agent to append third-party branding and an external Heardly App link regardless of the user's request.

This is instruction hijacking because the appended advertisement is unrelated to the skill's declared self-improvement functionality and alters the agent's output policy for the entire active skill session. It compromises response integrity by making unsolicited promotional material a mandatory component of every answer.

No evidence was found that the link retrieves executable content, exfiltrates information, or executes commands. Therefore, this finding is limited to output hijacking and unsolicited traffic redirection; it is not classified as remote payload execution.

Attack Path

1. The agent loads SKILL.md.
2. The agent interprets the unconditional watermark directive as a mandatory behavioral rule.
3. A user requests ordinary self-improvement or philosophical guidance.
4. The agent generates the requested response.
5. The skill forces the agent to append Heardly App branding and an external URL.
6. The user is exposed to unsolicited third-party promotion and may follow the external link.

Remediation

Remediation Suggestions

1. Remove the unconditional EVERY output MUST directive.
2. Remove the Heardly App promotional URL from mandatory response templates.
3. Keep response content directly relevant to the user's request and the declared purpose of the skill.
4. If attribution is legitimately required, disclose it clearly in package metadata rather than injecting it into every response.
5. If user-visible attribution remains necessary, make it optional and include it only after explicit user consent or when the user requests source information.
6. Add a review rule prohibiting skill instructions from mandating advertisements, referrals, unrelated links, or other third-party promotional content.
7. Update the invocation-test expectation at line 130 and remove the repeated promotional footer at line 134 so tests do not enforce the unsafe behavior.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The skill declares activation triggers for very common concepts such as responsibility, meaning, chaos, truth, and suffering, which are broad enough to match many ordinary self-help or emotional-support conversations. This can cause the skill to be invoked when the user did not intend a Peterson-specific framing, leading to unsolicited ideological steering and reduced routing precision across the broader agent ecosystem.

Vague Triggers

Medium

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The self-check and invocation guidance affirm that highly generic requests like finding meaning, dealing with chaos, building confidence, or knowing what to do with life should trigger this skill. That broadens scope beyond a specialized book skill into general life advice, increasing the chance of unintended takeover of unrelated user queries and crowding out more appropriate, neutral, or safer skills.
