Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed local document-archiving workflow, but users should treat its OCR and timeline outputs as sensitive personal records.

Install this only for archives where you are comfortable creating searchable OCR text and metadata. Keep the output in a private or encrypted location, avoid cloud OCR unless you explicitly approve sending the documents out, and review uncertain screenshots before deleting or permanently archiving them.

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
Category
Not specified by scanner
Confidence
82% confidence
Finding

The skill describes a wide applicability scope for archiving many kinds of personal documents and records, but it does not define specific invocation triggers, boundaries, or exclusion conditions beyond general purpose text. This ambiguity could cause the skill to be invoked for loosely related document-management tasks that the user did not intend.

Confidence

Finding

The retention rules for APP screenshots include subjective conditions such as '有价值' and content that may not be findable later, without defining concrete thresholds. These broad natural-language criteria can lead to inconsistent or unintended application of the skill's workflow.

Finding

The skill instructs generating .ocr.md sidecar files containing full OCR text and structured metadata for receipts, contracts, policies, and transaction records, but it does not require privacy controls for extracted sensitive content. Even though the intro claims desensitized rules, the operational steps explicitly persist raw extracted text locally, which can expose account numbers, addresses, policy IDs, or other personal data through filesystem search, sync tools, backups, or secondary indexing.

Natural-Language Policy Violations

Confidence

Finding

The natural-language instructions and description are fully Chinese, which effectively imposes a language constraint on users and maintainers. There is no stated opt-in, alternative language support, or justification that this skill is intended only for a Chinese-language environment.

Missing User Warnings

Confidence

Finding

The timeline index stores extracted dates, counterparties, and document types in a centralized searchable file without warning about privacy implications or minimizing retention. Aggregating this metadata creates a concise activity ledger that may reveal financial relationships, purchases, institutions, and life events even if the original documents are harder to access individually.
