Musik Tools AI Music Companion

Security checks for vulnerabilities and agentic risk

Overview

This is a document-only music helper skill with disclosed links and no code, credential access, persistence, or destructive behavior.

Installers should expect this skill to help structure music searches, lyric prompts, singing or pitch workflows, and AI music briefs. Review the linked external Musik Tools and GitHub pages before relying on them, and be aware that its generic music trigger terms could activate for broad music requests.

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
91% confidence
Finding
The trigger keywords are broad and overlap with common music-related user intents such as 'music finder', 'song finder', and 'lyrics generator', which can cause unintended invocation of the skill. In an agent ecosystem, this can redirect users into this skill when they did not explicitly request it, creating prompt-routing confusion, brand impersonation risk, and increased exposure to whatever instructions or links the skill contains.

Natural-Language Policy Violations

Low
Confidence
88% confidence
Finding
The manifest sets the skill language to "en" with no indication that users can select another language or that the English-only behavior is required for a documented regional or compliance reason. This can be a natural-language policy concern when locale is fixed without opt-in or justification.

Description-Behavior Mismatch

Low
Confidence
89% confidence
Finding
The manifest says this skill is a music discovery and audio-planning companion focused on songs, singing range, lyrics, and music-generation briefs. Including a product page for "AI Image" expands beyond that stated music-focused purpose, creating a semantic mismatch between the declared scope and the capabilities the skill appears to surface.
