Security audit

jev-calendar

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed calendar-classification workflow that uses user-approved WorkerKit and calendar connections without instructing calendar edits or hidden data transfer.

Install only if you are comfortable granting WorkerKit scoped access to read calendar event details and to install, deploy, and run its decision worker. Review the OAuth scopes, connected calendar identity, budget ceilings, and sample window before approving runs; do not paste OTPs, provider secrets, or manager keys into chat.

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

Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

If setup is complete, reuse the authorized connection and worker and proceed to readiness checks. This skill supports a new WorkerKit account but assumes OpenClaw is running. Otherwise the operator follows [OpenClaw setup](https://docs.openclaw.ai/start/getting-started) first. The person completes signup, terms acceptance, provider consent and any wallet funding.

Save this file as `skills/jev-calendar/SKILL.md` inside the active OpenClaw workspace, beside other skill folders. Do not nest it under workerkit-fleet: a discovered SKILL.md stops traversal below that directory. Run `openclaw skills list` to verify availability; start a new session if needed. Invoke `/skill jev-calendar` or ask for the classification task.
