Assessment
Verdict
Document-skills is the most polished of the Anthropic example-skill bundles: four coordinated SKILL.md files and Python renderers covering the full Office document surface, with production-grade conventions baked in. The xlsx skill ships with professional financial modeling standards — industry color-coding, SEC citation templates, formula error prevention rules — that signal the target user is finance and consulting, not hobbyists. LibreOffice subprocess calls use list-form argument arrays throughout, preventing shell injection. No network calls at runtime; everything executes locally against the user's files.

Evidence
Audit receipts
This listing is tied to a specific source commit and records both installation and risk checks.
Install check
✓ Pass
Installed via anthropics/skills GitHub marketplace (reserved name requires org source). All four sub-skills (xlsx, docx, pdf, pptx) resolved. No runtime deps beyond Python stdlib + python-docx/openpyxl.
Risk scan
✓ Clean
subprocess used in recalc.py, soffice.py, accept_changes.py to invoke LibreOffice and pdftoppm — all use list-form args with no shell=True; user-supplied filenames are list elements, not interpolated into a shell string. HTTP strings in xlsx SKILL.md are XML namespace URIs (openxmlformats.org), not live endpoints.
