/install universal-extractor
Description
Extract clean text from URLs, articles, documents, and files. Four extraction micro-services. Use when you need to pull content from web pages, PDFs, or any...
Usage Guidance
Do not send sensitive documents or secrets to this skill until the following are clarified: (1) what is the full API host/URL to which POST requests will be sent (domain, TLS expectations), (2) how are payments actually performed (does the agent need a wallet/private key or will billing be handled outside the agent?), (3) who operates the service and what is their privacy policy/retention rules, and (4) whether data is stored or logged by the service. If you still want to try it, test with non-sensitive sample files first, confirm expected costs, and prefer using a sandbox or throwaway account/wallet. If the publisher cannot supply API docs, host name, and a clear payment flow, do not install or use the skill for private data.
Capability Analysis
Type: OpenClaw Skill
Name: universal-extractor
Version: 1.0.0
The skill bundle consists of documentation (SKILL.md) for a 'Universal Extractor' service that processes URLs and documents via external API endpoints (/x402s/). No executable code is provided, and the instructions are clearly aligned with the stated purpose of text extraction without any signs of prompt injection, malicious intent, or unauthorized data access.
Capability Tags
Capability Assessment
Purpose & Capability
Name/description (text extraction) aligns with the provided endpoints (clean-url, extract-article, extract-document, extract-file). However the SKILL.md omits the host/URL root for the POST endpoints (it only gives paths like /x402s/clean-url) and also references a paid 'x402' protocol without declaring any credentials or wallet requirements — this is inconsistent with a self-contained extractor skill and suggests missing integration details.
Instruction Scope
Instructions explicitly tell the agent to POST base64-encoded files and URLs to external endpoints, which would transmit arbitrary user content (including sensitive data). There is no guidance on which hostname to use, how to authenticate, or how to handle clearance/consent. The instructions grant the agent broad discretion to send user content to an unspecified external service.
Install Mechanism
No install spec and no code files — instruction-only skill. This minimizes on-disk risk because nothing will be written or executed by an installer, which is appropriate for a simple API-invoking skill.
Credentials
The SKILL.md claims 'No API keys needed' but indicates requests are paid in USDC via an 'x402' protocol on Base — this implies a wallet/transaction signing mechanism or external payment flow that is not declared. The skill requests sending content but declares no credentials; the absence of any declared credential or payment mechanism is disproportionate to the stated paid API behavior and is an unresolved inconsistency.
Persistence & Privilege
The skill does not request always-on presence and uses normal agent invocation rules. It does not declare changes to other skills or system-wide settings.
