Security checks for vulnerabilities and agentic risk

Overview

This local PII redaction skill is mostly coherent, but its JSON workflow can automatically persist raw sensitive data in a predictable sidecar file without strong file-safety controls.

Use this only on trusted local paths, and avoid the JSON + --output workflow unless you explicitly need the raw entity map. Treat any *.entity-map.json file as highly sensitive, delete it when no longer needed, and do not place outputs in shared, synced, indexed, or backed-up directories.

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: 87% confidence
Finding: The skill declares executable behavior that reads and writes files but does not specify any explicit tool scope or permission boundaries. In an agent environment, this can allow broader-than-intended file access, increasing the risk that the agent reads unsanitized sensitive inputs or writes sensitive sidecar outputs without policy enforcement.
