The 5 AM Club

Security checks for vulnerabilities and agentic risk

Overview

The skill is a self-improvement guide with no code or system access, but it forces promotional branding and links into every response, including out-of-scope answers.

Review before installing if you do not want skill-generated answers to include mandatory Heardly branding or external links. The skill has no executable code or privileged access, but its response rules are overbroad and may affect unrelated conversations while active.

A.I.G

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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The trigger list is broad and includes generic productivity and discipline phrases that can match many unrelated user requests. This can cause the skill to activate outside its intended scope, leading to inappropriate routing, response hijacking, or suppression of better-matched skills.
Content: No source excerpt is available for this finding.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 95% confidence
Finding: The phrase saying the skill will appear whenever it "senses this book could help" creates an ambiguous, subjective activation rule with no clear boundary. That increases the chance of overbroad invocation and makes the skill easier to surface in contexts where it is not the best or intended tool.
Content: No source excerpt is available for this finding.

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 85% confidence
Finding: This markdown file repeatedly frames 5-6 AM as the required 'Victory Hour,' which imposes a specific time-based routine as a universal expectation. Under the policy rule, forcing a specific schedule or locale-related convention without opt-in can be a natural-language policy concern.
Content: No source excerpt is available for this finding.
