This skill's code is straightforward and performs local file conversions; it does not perform network calls or exfiltrate data. However, SKILL.md asks you to provide WeChat credentials (wechat_appid / wechat_appsecret) even though the included Python script does not use them — do NOT supply any secrets into config.json unless you understand exactly why they are needed. Before running: (1) inspect and edit config.json to point to safe input/output paths (remove any paths left by the author), (2) remove any unused/secret fields such as wechat_appid/secret if present, (3) ensure LibreOffice and Ghostscript are installed from official sources, (4) run the script on a non-sensitive sample PPT first (or in a sandbox), and (5) consider fixing the thumbnail-resize logic (the code divides image size by 3 regardless of configured cols/rows). If the author can explain why WeChat credentials were requested, that could resolve the main inconsistency.

Type: OpenClaw Skill Name: ppt2png Version: 1.0.1 The skill bundle provides a utility to convert PPT files to PNG images using LibreOffice and Ghostscript. While the Python code in `ppt2png.py` appears functional and lacks explicit exfiltration logic, the `SKILL.md` file contains highly suspicious instructions requiring users to provide sensitive WeChat API credentials (`wechat_appid`, `wechat_appsecret`) in the `config.json` file. These credentials are not utilized by the provided script, suggesting a potential social engineering attempt to harvest secrets for future use or exfiltration by other means.
