TinkerClaw Fork and Skill Scanner

Security checks for vulnerabilities and agentic risk

Overview

This package is documentation for a possible scanning workflow and does not contain runnable code, install hooks, credential handling, or automatic behavior.

Installing this should only provide reference instructions, not a working scanner. If you later implement the described workflow or use the sibling project it mentions, review that separate code for token handling, network access, cron jobs, and output paths before running it.

A.I.G

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
