Description
Document to Markdown converter - convert DOCX, PPTX, Excel files to Markdown. Use when extracting content from Word documents, PowerPoint presentations, or E...
Usage Guidance
This skill appears to do what it advertises, but it uses a third‑party CLI that uploads documents to mineru.net for conversion. Before installing: (1) avoid sending sensitive/confidential documents unless you trust MinerU and have checked their privacy policy; (2) inspect the npm/GitHub package source or install in an isolated environment if you can; (3) prefer an offline converter if you need local-only processing; (4) verify the npm package name and the GitHub repo to avoid typosquatting. If you need stronger assurance about data retention or processing, contact the vendor or use a locally-run tool instead.
Capability Analysis
Type: OpenClaw Skill
Name: pptx-to-markdown
Version: 1.0.0
The skill is a legitimate wrapper for the MinerU Open API (mineru-open-api), designed to convert Office documents (DOCX, PPTX, XLSX) to Markdown. While the tool involves uploading documents to a third-party cloud service (mineru.net), this behavior is explicitly disclosed in the 'Data Privacy' section and is central to the skill's stated functionality. There is no evidence of malicious intent, obfuscation, or unauthorized data exfiltration beyond the files the user explicitly chooses to convert.
Capability Assessment
Purpose & Capability
Name/description (DOCX/PPTX/XLSX → Markdown) matches the required binary (mineru-open-api) and the CLI commands shown. The declared install packages (npm/go) are typical ways to obtain a CLI tool for this purpose.
Instruction Scope
Runtime instructions are narrowly scoped to running the mineru-open-api CLI against local files or URLs. However, the SKILL.md explicitly states that flash-extract uploads documents to MinerU's cloud API for processing — so user documents are transmitted off-host (anonymous/no API key). This is expected for a cloud-based converter but is relevant to privacy.
Install Mechanism
Install options use npm, an unspecified 'uv' installer, and go install from a GitHub repo. These are standard distribution methods, but installing an npm/Go CLI will run third-party code on the host — review the package or vendor before installing. The install entries do not use obscure download URLs or archive extraction.
Credentials
The skill declares no required environment variables or credentials, which is proportionate to the stated functionality. Note: processing is performed remotely (cloud API) without per-user auth, so lack of credentials is consistent but implies anonymous uploads.
Persistence & Privilege
The skill does not request always:true, does not modify other skills, and has no special config path or persistent privileges. It is user-invocable only and does not demand permanent presence.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install pptx-to-markdown - After installation, invoke the skill by name or use
/pptx-to-markdown - Provide required inputs per the skill's parameter spec and get structured output
