Security audit

Impeccable ans Complete UX/UI Skill

Security checks for vulnerabilities and agentic risk

Overview

This is a UI design guidance skill with no executable code; its broad UI advice and context-gathering steps are disclosed and purpose-aligned.

Before installing, expect this skill to influence most UI-related work and to ask for design context, including checking a project-local .impeccable.md file or invoking a context setup command when context is missing. It does not ship executable code or request credentials, but users working in localized products should adapt its English UX-writing advice to their locale.

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
Confidence
96% confidence
Finding
The manifest description says to 'Use when building or reviewing any UI,' which is broad enough to overlap with many ordinary frontend-related requests. It does not provide clear trigger boundaries, exclusions, or negative examples, so the skill could be invoked in unintended situations.

Natural-Language Policy Violations

Medium
Confidence
83% confidence
Finding
The guidance bans labels like 'OK', 'Submit', and 'Yes/No' as universal rules, but these recommendations are framed from an English UX-writing perspective and may not transfer appropriately to other languages or locales. The file does discuss translation later, but it does not offer locale choice or clarify that these prescriptions should be adapted based on the user's language.
