Bestax: Optimize CSS
Security checks for vulnerabilities and agentic risk
Overview
The skill provides straightforward CSS optimization instructions and does not show hidden execution, data collection, persistence, or deceptive behavior.
Install only if you want an agent to inspect and edit a frontend project's CSS imports, Sass file, and possibly dev dependencies. Review any proposed package or import removals before applying them, especially if icon assets or helper classes may still be used indirectly.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
