Security audit

Churn Prevention

Security checks for vulnerabilities and agentic risk

Overview

This skill is a plain-language SaaS churn and payment-recovery guide with no executable code or hidden system access.

Installers should treat this as business and product guidance, and should still review any billing-provider or cancellation-flow changes before applying them in production, especially where cancellation and data-retention laws apply.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill description is unusually broad and includes many generic churn/retention phrases, which can cause the agent to invoke this skill in loosely related conversations. Over-broad routing is a real security and safety issue because it increases the chance of unintended file reads, tool suggestions, or persuasive business guidance being applied outside the user's actual intent.

Vague Triggers

Confidence
95% confidence
Finding

This JSON eval file is a manifest-type file, so vague-trigger checks apply. The expected output and assertion explicitly require the skill to 'trigger on casual phrasing,' but they do not define boundaries, specific allowed phrases, or negative examples, creating a risk of unintended invocation from everyday language.

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.

md
- Inform users about data retention period post-cancel
- Offer data export before account deletion
- Honor deletion requests within 30 days
- Don't use post-cancel data for marketing without consent

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