在 OpenClaw 中安装
/install ocr-local
功能描述
Extract text from images using Tesseract.js OCR (100% local, no API key required). Supports Chinese (simplified/traditional) and English.
安全使用建议
Install only if you are comfortable with npm dependencies and a first-run download of Tesseract language data. For restricted or offline environments, preload or vendor the language data through a controlled process before use, and avoid OCRing sensitive images unless you are comfortable with the extracted text appearing in the agent session.
能力评估
Purpose & Capability
The skill’s purpose is local OCR using Tesseract.js, and the script reads a user-specified image path, runs OCR, and prints text or JSON output without requesting credentials or unrelated access.
Instruction Scope
The wording “100% local” is somewhat imprecise because the docs also disclose first-run Tesseract language-data downloads and later local caching; this is a transparency caveat, not evidence of hidden behavior.
Install Mechanism
Installation uses Node/npm with the tesseract.js dependency and runtime language-data downloads. This is coherent for Tesseract OCR, though not ideal for strictly offline or pinned-supply-chain environments.
Credentials
Access is proportionate to OCR: it operates on image files the user passes in and does not show image upload, OCR-output exfiltration, environment-variable access, shell execution, or credential handling.
Persistence & Privilege
The only persistence indicated is local caching of downloaded language data. There is no evidence of background workers, privilege escalation, modification of other skills, or durable agent behavior.
