Pptx To Markdown

Document to Markdown converter - convert DOCX, PPTX, Excel files to Markdown. Use when extracting content from Word documents, PowerPoint presentations, or E...

Security Scan

The skill is internally consistent: it wraps a CLI (mineru-open-api) to upload & convert office documents to Markdown and does not request unrelated credentials or system access.

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.

Assessment

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.
