Usage Guidance
Install only if you are comfortable with a spreadsheet helper that runs LibreOffice, modifies local Excel files during recalculation, writes a persistent LibreOffice macro into your user profile, and may compile/load a native compatibility shim. Prefer running it in a disposable or isolated environment and work on copies of important spreadsheets.
Capability Analysis
Type: OpenClaw Skill
Name: xlsx-cn
Version: 1.0.1
The skill is classified as suspicious primarily due to the use of `LD_PRELOAD` in `scripts/office/soffice.py` and potential shell injection in `scripts/recalc.py`. The `soffice.py` script dynamically compiles and loads a C shim using `gcc` and `LD_PRELOAD` to enable LibreOffice functionality in sandboxed environments. While the C code appears to be a legitimate workaround, this is a highly privileged and risky operation that could be abused if the skill bundle were compromised. Additionally, `scripts/recalc.py` passes the Excel filename directly to `soffice` via `subprocess.run`, creating a potential shell injection vulnerability if the filename were user-controlled.
Capability Assessment
Purpose & Capability
Creating, reading, editing, and recalculating .xlsx files matches the stated purpose, but the bundled office helpers also support DOCX/PPTX pack, unpack, and validation paths that are not advertised in the Excel-focused description.
Instruction Scope
The SKILL.md discloses use of scripts/recalc.py and says LibreOffice is automatically configured, but it does not clearly explain that recalculation installs a persistent LibreOffice macro, saves the workbook in place, and may use a gcc-built LD_PRELOAD shim.
Install Mechanism
There is no install-time execution or package-install hook in the artifact, but metadata declares no dependencies despite runtime reliance on local tools such as LibreOffice, gcc, timeout or gtimeout, and git for some helper paths.
Credentials
LibreOffice subprocess use is expected for formula recalculation, but dynamically compiling a shared object in a predictable temp location and injecting it into LibreOffice with LD_PRELOAD is high-impact and under-scoped for normal spreadsheet processing.
Persistence & Privilege
scripts/recalc.py writes Module1.xba into the user's LibreOffice application profile and leaves it there, creating persistent application state outside the target workbook.
