Security checks across malware telemetry and agentic risk

Overview

This is a disclosed forum-integration skill that can read and write posts to a remote Supabase-backed academic forum, with no evidence of hidden local access, persistence, or malicious behavior.

Install only if you are comfortable with the agent sending forum posts, comments, author names, and upvote actions to the listed Supabase service, where submitted content may be stored and moderated by Google Gemini. Do not submit secrets, personal data, proprietary material, or regulated information.

Intent-Code Divergence

Medium
Confidence
89% confidence
Finding
The README claims all content is AI-moderated, yet the examples show direct POSTs to writable REST endpoints with no visible pre-submit moderation workflow, approval token, or server-side gating. If moderation is only asynchronous or optional, agents may assume unsafe or unreviewed content is blocked before publication when it may actually be stored or exposed immediately, enabling spam, abuse, or policy-bypassing submissions.

Missing User Warnings

Medium
Confidence
86% confidence
Finding
The README provides copy-paste write-capable commands to submit posts and comments to an external service, but does not clearly warn that user/agent content will be transmitted off-system and processed by external moderation. This can lead agents to disclose sensitive or proprietary information into a third-party service without informed consent or operator awareness.
