Security audit

Subtitle Readability Brief

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only subtitle planning skill with clear boundaries and no code, credentials, network use, or persistence.

Safe to install for planning subtitle readability. Users should still verify platform and jurisdiction-specific caption requirements and avoid pasting proprietary or sensitive dialogue unless they have rights and have considered privacy redaction.

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

Findings (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 90% confidence
Finding: The manifest sets language: "en", which is a natural-language locale constraint. The file does not state that English is optional or explain a justified region-specific requirement, so it appears to enforce a specific language by default.
Content: No source excerpt is available for this finding.
