The Agent Skills Directory

[COMMAND_EXECUTION]: The skill provides templates and code patterns for the agent to generate and execute Python code and VBA macros to manipulate spreadsheet data.
[DATA_EXFILTRATION]: Contains implementation details for emailing generated Excel files using Python's smtplib, which is a documented feature for automated reporting workflows.
[EXTERNAL_DOWNLOADS]: References several reputable and widely-used software packages for spreadsheet processing, such as pandas, openpyxl, xlsxwriter, and exceljs.
[PROMPT_INJECTION]: The skill processes data from external Excel files, creating a surface for indirect prompt injection.
Ingestion points: Files are read using pd.read_excel as described in SKILL.md and references/python-automation.md.
Boundary markers: The skill lacks specific instructions to the model to ignore embedded commands in the Excel data, although it does recommend structural validation.
Capability inventory: The agent has the ability to write to the file system and perform network operations (SMTP email).
Sanitization: Includes basic data cleaning steps like stripping whitespace and type coercion, but does not explicitly sanitize for prompt-injection style strings.
