Usage Guidance
This skill appears coherent for extracting .pptx files using the MinerU CLI, but check a few things before installing: 1) Verify the npm package (mineru-open-api) and the GitHub repo (opendatalab/MinerU-Ecosystem) to ensure they're the official project and review install scripts. 2) Understand that MINERU_TOKEN is needed for full 'extract' functionality but 'flash-extract' can run without a token — the registry metadata marking the token as required is inconsistent with the README. 3) Do not paste sensitive tokens into a webpage you don't trust; create a token with minimal scope and rotate/delete it if you stop using the skill. 4) If you must install globally, consider installing in a sandbox or container first to inspect runtime behavior.
Capability Analysis
Type: OpenClaw Skill
Name: pptx-extract
Version: 0.4.0
The skill is a legitimate wrapper for the MinerU document intelligence engine (developed by Shanghai AI Lab) to extract content from PowerPoint files. It utilizes the official 'mineru-open-api' CLI tool and connects to the verified domain mineru.net for processing. No evidence of malicious intent, unauthorized data exfiltration, or prompt injection was found in SKILL.md or the metadata.
Capability Assessment
Purpose & Capability
The skill name/description (PPTX -> Markdown via MinerU) aligns with required binary (mineru-open-api) and the described commands. Minor incoherence: SKILL.md documents a no-token 'flash-extract' mode, but the registry metadata lists MINERU_TOKEN as a required env var/primary credential, which implies the token is mandatory even though the tool can operate in tokenless mode for quick extracts.
Instruction Scope
Runtime instructions are narrowly scoped to running the mineru-open-api CLI (flash-extract, extract, auth) against local files or URLs. They do not instruct reading unrelated system files or other environment variables. It does call an interactive 'mineru-open-api auth' and references exporting MINERU_TOKEN.
Install Mechanism
Install paths are typical: npm package 'mineru-open-api' and a Go 'go install' from github.com/opendatalab. These are expected for a CLI tool, but npm installs run package scripts during install and Go installs pull code from GitHub — users should verify the npm package and GitHub repo before installing globally.
Credentials
Only MINERU_TOKEN is declared as the required credential, which matches the 'extract' and 'crawl' functionality. The metadata's blanket requirement of MINERU_TOKEN is inconsistent with the documented no-token 'flash-extract' mode; otherwise the requested credential is proportionate to the skill's purpose.
Persistence & Privilege
The skill is not always-installed (always: false), requests no config paths, and does not ask to modify other skills or system settings. Autonomous invocation is allowed (platform default) but not combined with other concerning privileges.
