Check Messages

Security checks for vulnerabilities and agentic risk

Overview

This is a plain Aicoo message-checking skill that reads inbox data with the user's API key, with privacy and trigger-scoping caveats but no hidden code or persistence.

Install this only if you are comfortable letting the agent use your Aicoo API key to fetch and display conversation contents, contact identities, timestamps, and pending request details. Use explicit filters when possible, and treat the agent session as containing private inbox data.

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

Vague Triggers

Medium
Confidence
95% confidence
Finding
The manifest includes many broad natural-language trigger phrases such as 'show conversations', 'agent activity', and 'conversation history', which can match requests outside a narrowly intended inbox-review action. In an agent environment, overbroad invocation can cause the skill to activate on ambiguous prompts and retrieve private inbox data when the user may have meant something else, creating an unintended data exposure path.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly instructs retrieval and presentation of message bodies, contact identities, usernames, and timestamps without any privacy warning, minimization guidance, or confirmation before display. Because inbox contents and contact metadata are sensitive, automatically surfacing them can expose third-party personal information or confidential conversations to anyone with access to the session or to a misinterpreted user request.
