Prettierrc Validator

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward local Prettier configuration validator with no evidence of hidden, destructive, network, credential, or persistence behavior.

Install this only if you are comfortable running a local Python validator against Prettier configuration files. Review its lint output before using it in CI, because it exits nonzero on errors by design.

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
