Usage Guidance
Install only if you are comfortable running this in an isolated environment. Back up both Office documents and any existing LibreOffice macros first, and avoid using it on untrusted Office files until the LD_PRELOAD shim, persistent macro setup, and archive extraction limits are addressed.
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
Credentials
scripts/office/soffice.py attempts to work around sandbox socket restrictions by compiling a shared library in a predictable temp path and injecting it into LibreOffice with LD_PRELOAD, which is high-impact and under-contained for spreadsheet processing.
Install Mechanism
There is no separate installer, dependency list, or network retrieval in the package metadata; the risky behavior is in runtime helper scripts invoked by the documented recalculation workflow.
Instruction Scope
The skill discloses LibreOffice recalculation and automatic setup, but it does not clearly disclose that setup may compile a native shim, set LD_PRELOAD, or overwrite a persistent LibreOffice macro module.
Persistence & Privilege
scripts/recalc.py writes Module1.xba into the user's normal LibreOffice profile and can replace an existing module without backup or explicit consent; it does not request administrator privileges or install a service.
Purpose & Capability
The main instructions are coherent for creating, editing, and analyzing Excel files, but the shipped scripts also include DOCX/PPTX unpacking, validation, and tracked-change modification helpers that are not disclosed by the Excel-focused metadata.
