Csv Toolkit

Security checks for vulnerabilities and agentic risk

Overview

This is a local CSV utility whose file reading and writing match its stated purpose, with a spreadsheet-formula safety caveat for untrusted data.

Install only if you are comfortable with a local command-line helper reading input files and writing outputs you specify. Be careful opening generated CSVs from untrusted CSV or JSON in spreadsheet apps, because formula-like cells may remain active unless sanitized separately.

Vulnerability Patterns

Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 89% confidence
Finding: The skill advertises and demonstrates file read/write behavior through command usage, but it does not declare any tool scope such as permissions or allowed-tools. That omission weakens policy enforcement and reviewability, because consumers cannot easily tell that the skill operates on local files or constrain it appropriately before use.
Content: No source excerpt is available for this finding.
