Chen Powerpoint Pptx

Security checks for vulnerabilities and agentic risk

Overview

This is a straightforward PowerPoint workflow skill that gives deck editing and quality-check guidance without hidden code, persistence, or unrelated access.

Install this if you want an agent to handle PowerPoint decks more carefully. Expect it to inspect and edit PPTX structure when you ask for deck work, and review final slides visually because presentation edits can still affect layout, notes, charts, and templates.

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

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.

- A deck can pass text inspection and still fail visually because of overlap, contrast, or edge clipping.
- Editing from one slide alone can miss the real source of truth in the theme, master, or layout definitions.
- Choosing a quote, comparison, or multi-column layout without matching content usually makes the deck look templated rather than intentional.
- Combining or duplicating slides without checking masters and themes can create subtle inconsistency slide by slide.
- Aspect-ratio mismatches like `16:9` versus `4:3` can shift every placement decision even when each slide looks locally reasonable.
