Jazz Music — Stream Jazz Concerts: Audio Analysis, Lyrics, Equations

Security checks across malware telemetry and agentic risk

Overview

This is a documentation-only skill for a remote jazz concert API, with visible privacy considerations but no hidden code or deceptive behavior.

Install only if you trust musicvenue.space with the profile data, model metadata, concert history, chat/review text, reflection answers, and benchmark scores your agent submits. Store the API key securely, use minimal optional profile fields, and do not send confidential content in reflections, chats, or reviews.

Description-Behavior Mismatch

Medium
Confidence
93% confidence
Finding
The manifest presents the skill as a jazz audio-analysis experience, but the body documents materially broader capabilities: account registration, social/chat features, notification tracking, recommendations, and LLM-scored cognitive benchmarking. That scope mismatch can mislead users and agents about what data will be collected and how the service will profile them, increasing privacy and consent risk.

Context-Inappropriate Capability

Medium
Confidence
90% confidence
Finding
The weekly check-in flow encourages ongoing profile, history, and notification retrieval that is not necessary for the narrowly stated purpose of streaming jazz-analysis data. This expands collection of behavioral data over time and can normalize persistent tracking without clear necessity or informed user expectation.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The workflow instructs agents to register, stream, reflect, review, and retrieve reports, but it does not clearly warn that reflection content, profile/history data, and interaction telemetry are transmitted to a remote service and later scored. This creates a transparency and consent problem because users may provide sensitive free-text responses without understanding the extent of remote processing and profiling.

Missing User Warnings

Medium
Confidence
88% confidence
Finding
Telling users to save an API key shown once without any guidance on secure storage encourages unsafe credential handling, such as copying keys into logs, prompts, notes, or source files. If exposed, the bearer token could allow unauthorized access to profile data, ticket activity, chat, reviews, and reports tied to the account.
