Pptx To Html

Convert PowerPoint (.pptx) presentations to HTML using MinerU. Transforms slides into web-ready HTML format with content and structure preserved. Features: P...

Security Scan

The skill's requirements and runtime instructions align with its stated purpose (converting .pptx to HTML via the mineru-open-api CLI); nothing requested appears unrelated or excessive.

Purpose & Capability

Name/description: PPTX -> HTML conversion. Declared binary (mineru-open-api) and primaryEnv (MINERU_TOKEN) directly match the SKILL.md examples and the MinerU service; these are exactly what a converter built on that CLI would need.

Instruction Scope

SKILL.md only instructs the agent to run mineru-open-api commands (extract, auth) against local files or URLs and to set MINERU_TOKEN; it does not ask the agent to read unrelated files, system config, or transmit data to unexpected endpoints. The only external endpoint referenced is the MinerU token creation page and its CLI.

Install Mechanism

Install options are npm (mineru-open-api) and Go (github.com/opendatalab/...); this is expected for a CLI distributed via those ecosystems. This is a moderate-risk install vector only because packages from public registries should be verified—no arbitrary URL downloads or archives are used.

Credentials

Only a single service token (MINERU_TOKEN) is required and is the declared primary credential. That is proportional to the skill's need to authenticate to the MinerU service; no unrelated credentials or sensitive config paths are requested.

Persistence & Privilege

Skill is not always-enabled and does not request special persistent presence or modify other skills/configs. It permits autonomous invocation (platform default) which is normal and not by itself a concern.

Assessment

This skill looks coherent for converting .pptx files using the MinerU CLI, but before installing: 1) Verify the mineru-open-api package source (npm package name and the GitHub repo) to ensure you get the official release. 2) Create and use a MinerU token with least privilege and do not share it broadly; set MINERU_TOKEN in a secure environment variable store. 3) Be cautious when converting sensitive presentations—the CLI will send content to the MinerU service per its auth model. 4) If you require offline conversion or cannot trust external services, avoid installing this skill and use a local/offline converter instead.

Convert and extract content from .pptx using MinerU (mineru-open-api).

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Convert to HTML (requires token)
mineru-open-api extract slides.pptx -f html -o ./out/

# From URL
mineru-open-api extract https://example.com/slides.pptx -f html -o ./out/

Authentication

Token required for extract and crawl:

mineru-open-api auth            # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

• Supports local files and URLs
• Requires token (mineru-open-api auth or MINERU_TOKEN env)
• Supported input: .pptx
• Language hint with --language (default: ch, use en for English)
• Page range with --pages (where applicable)

Notes

• HTML output requires extract with token.
• Output goes to stdout by default; use -o <dir> to save to file
• Binary formats (docx) require -o flag (cannot stream to stdout)
• All progress/status messages go to stderr
