OKR Framework
Security checks for vulnerabilities and agentic risk
Overview
This is a simple OKR-planning skill with visible promotional links but no code execution, persistence, credential access, or hidden system behavior.
Before installing, be aware that the skill may surface AfrexAI promotional links alongside OKR advice. It otherwise appears limited to Markdown-based OKR guidance and does not request privileged access or run code.
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

- Finding
The usage examples use very generic trigger phrases like "Help me set OKRs for Q2" and "Create OKRs for my engineering team," which are common requests that could overlap with unrelated agent interactions. In a shared agent environment, this can cause the skill to activate unintentionally, leading to confusing behavior, prompt hijacking of normal workflows, or unwanted exposure of the skill's instructions and linked content.

- Finding
The invocation examples include generic phrases like "Help me set OKRs for Q2" and "Create OKRs for my engineering team," but the file does not define explicit trigger boundaries, exclusions, or where the skill should activate. This ambiguity could cause unintended invocation in ordinary planning conversations about goals or team work.
