✓
Purpose & Capability
Name/description (generate formatted Excel files) align with the provided SKILL.md and the included Python implementation. Nothing requested by the skill is unrelated to spreadsheet generation.
✓
Instruction Scope
SKILL.md limits behavior to constructing a 2D list and calling create_excel_file; it does not instruct the agent to read unrelated files, environment variables, or contact external endpoints beyond dependency installation.
ℹ
Install Mechanism
There is no registry install spec, but the included script will attempt to auto-install 'openpyxl' via subprocess pip install at runtime. The package is a well-known PyPI package (no arbitrary URL), but runtime installation requires network access and writes to the Python environment.
✓
Credentials
The skill requests no environment variables, credentials, or config paths. The code does not read secrets or external configuration.
✓
Persistence & Privilege
always is false; the skill does not modify other skills or system-wide settings. It writes only the generated .xlsx file to the current filesystem.
Assessment
This skill appears to do exactly what it says: generate formatted .xlsx files. Before installing or running it, be aware the bundled script will try to run 'pip install openpyxl' if the package is missing—which requires network access and will install into the agent's Python environment. If you prefer not to allow runtime installs, pre-install openpyxl in the environment or review/modify the script to remove the auto-install behavior. Also run the skill in a safe environment if you are concerned about where files are written (it saves files to the current working directory and will create/overwrite the named .xlsx). Otherwise there are no signs of data exfiltration, hidden endpoints, or unrelated credential access.

Like a lobster shell, security has layers — review code before you run it.
