Security audit

PM Toolkit - Excalidraw - "Messy Thoughts" to "Visual Spec" in 30 seconds.

Security checks across malware telemetry and agentic risk

Overview

This skill appears to be a straightforward local diagram generator that creates an Excalidraw file from user-provided product notes.

Install only if you are comfortable with a bundled Python script creating a temporary JSON input, generating a local .excalidraw file, and deleting that temporary input afterward. Check the output path before use, since the workflow may overwrite an existing file with the same name.

MCP Least Privilege
Confidence
70% confidence
Finding
Without declared permissions the skill's intent is opaque and cannot be validated.

Missing User Warnings

Low
Confidence
88% confidence
Finding
This markdown skill instructs the agent to create a temporary JSON file as part of normal operation, which modifies user storage. Although the steps describe what to do, they do not explicitly warn the user that local files will be created and later removed, which is the kind of data-affecting behavior SQP-2 covers for markdown files.

Missing User Warnings

Low
Confidence
91% confidence
Finding
The cleanup step explicitly tells the agent to delete the temporary JSON input file, which is a destructive filesystem action. The document does not include a user warning or caution that temporary files will be removed during execution.
