Snip Compressor

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local conversation-summary tool whose file access and output behavior match its stated purpose.

Install only if you are comfortable letting the tool process conversation transcripts you provide. Prefer explicit invocation for compression and avoid feeding sensitive chat histories unless the resulting Markdown summary is acceptable to store or share locally.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding

The skill advertises executable behavior through its usage instructions and metadata but does not declare an explicit tool scope such as permissions or allowed-tools. That creates an authorization ambiguity where a host may expose file read/write capabilities more broadly than intended, which is especially relevant here because the skill processes conversation files and writes compressed output.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The activation guidance includes broad, everyday phrases like "continue," "where were we," and similar variants that can match normal conversation rather than an intentional request to invoke this skill. This can cause accidental triggering in unrelated contexts, leading to unintended summarization of conversation history and possible exposure or transformation of sensitive context.
