churn-prevention

Security checks for vulnerabilities and agentic risk

Overview

This is a plain Markdown guidance skill for SaaS churn prevention and payment recovery, with no hidden code or install-time behavior found.

Before installing, treat this as business-process guidance rather than legal or billing-system authority. Review any cancellation, payment retry, account pause, data retention, and deletion policies with the appropriate business and legal owners, especially for click-to-cancel, auto-renewal, and privacy requirements.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The description says to use the skill whenever a user wants to 'reduce churn' or 'implement retention strategies' and 'whenever someone is losing subscribers,' which are broad natural-language conditions rather than narrowly scoped triggers. This can overlap with general business, marketing, analytics, or product conversations and may cause unintended invocation.

Vague Triggers

Category

Confidence
93% confidence
Finding

The eval explicitly expects the skill to trigger on casual phrasing, which encourages broad and potentially imprecise activation. In an agent environment, overly broad routing can cause the churn-prevention skill to activate for loosely related retention or cancellation language, leading to incorrect tool/skill selection, reduced reliability, and possible bypass of more appropriate specialized skills.

Autonomous Decision Making

Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

- Inform users about data retention period post-cancel
- Offer data export before account deletion

- Don't use post-cancel data for marketing without consent

### General Best Practices
- Always show a clear path to complete cancellation

Missing User Warnings

Confidence
89% confidence
Finding

The playbook says data may be deleted after prolonged non-payment but does not consistently require an explicit, prominent warning before that destructive outcome occurs. In a churn-prevention and dunning context, this omission can lead teams to implement pause/cancellation flows that surprise users with irreversible data loss, increasing legal, trust, and customer-harm risk.
