Generating Evaluation Rubrics

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed classroom rubric generator with a minor dependency-installation caveat, not evidence of malicious behavior.

Install only if you are comfortable with a skill that may read lesson-plan files you provide and create local rubric files. Before allowing Excel generation, confirm any pip install request and note that the referenced helper script/example files may need to exist for the skill to work fully.

Missing User Warnings

Confidence
97% confidence
Finding
The skill explicitly instructs the agent to run `pip install openpyxl>=3.0.0` automatically when the dependency is missing, without requiring prior user confirmation. Even though the package appears legitimate and the context is a rubric-generation tool, automatic dependency installation expands the execution surface, can modify the environment unexpectedly, and may expose the system to package-supply-chain or policy violations.
