在 OpenClaw 中安装
/install tesseract-ocr
功能描述
Extract text from images using the Tesseract OCR engine directly via command line. Supports multiple languages including Chinese, English, and more. Use this...
安全使用建议
Install Tesseract only from trusted package managers, run OCR only on files you intend to process, and review output paths before saving results. The skill is local-command based, but its behavior is disclosed and proportionate to OCR.
功能分析
Type: OpenClaw Skill
Name: tesseract-ocr
Version: 1.0.0
The skill bundle is designed to use the Tesseract OCR command-line tool, which is a legitimate utility. However, the `SKILL.md` instructions demonstrate executing `tesseract` with user-provided file paths and language codes. This inherently introduces a shell injection vulnerability if the OpenClaw agent does not properly sanitize user input before constructing and executing the `tesseract` command. While the skill itself does not contain malicious code or explicit prompt injection attempts, the direct exposure of a command-line interface with user-controlled arguments creates a high-risk scenario for potential Remote Code Execution (RCE) via shell injection, classifying it as suspicious due to this critical vulnerability risk.
能力评估
Purpose & Capability
The stated purpose is extracting text from images, and the documented capability is limited to Tesseract OCR commands for image input, language selection, stdout, or an optional output file.
Instruction Scope
The skill uses local command execution with user-chosen file paths and language codes, which is expected for a CLI OCR skill; the artifact does not include a wrapper script or evidence of hidden command construction.
Install Mechanism
It asks users to install Tesseract and language packs through apt or Homebrew, including sudo on Debian/Ubuntu; this is disclosed and purpose-aligned but depends on trusted system package sources.
Credentials
No credentials, tokens, network APIs, broad indexing, unrelated file access, or external data transmission are requested.
Persistence & Privilege
No persistence, background agents, privilege retention, account access, or autonomous mutation behavior is described.
如何使用

/install tesseract-ocr - 安装完成后，直接呼叫该 Skill 的名称或使用
/tesseract-ocr触发 - 根据 Skill 的参数说明提供必要输入，即可获得结构化输出
