功能描述
调用 OCR.space 免费 API 识别图片中的文字
安全使用建议
This skill appears to do what it says: it reads images and uploads them to OCR.space using the free test key. Before installing, consider: (1) it will transmit image data to a third-party server — don't send sensitive images unless you accept that. (2) You need Python packages 'requests' and 'Pillow' installed; SKILL.md doesn't list them, so install them (pip install requests pillow) or run the script in a controlled environment. (3) If you plan to use a paid API key, remove the hardcoded 'helloworld' and provide your key securely (avoid committing it into the file). (4) Test the script locally to confirm behavior and network calls before allowing any agent to invoke it autonomously.
功能分析
Type: OpenClaw Skill
Name: ocr-space
Version: 1.0.0
The skill bundle provides legitimate OCR functionality by interfacing with the OCR.space API. The Python script (ocr_space.py) uses the service's documented 'helloworld' test key and performs standard image processing and network requests to extract text from images. No evidence of malicious intent, data exfiltration, or prompt injection was found; the code logic aligns perfectly with the stated purpose in SKILL.md.
能力评估
Purpose & Capability
Name/description match implementation: the script posts images to https://api.ocr.space/parse/image using the free test key ('helloworld') and returns parsed text. No unrelated services, binaries, or credentials are requested.
Instruction Scope
SKILL.md and the script confine actions to reading the provided image path (or accepting base64), optionally compressing it, and POSTing it to the OCR.space API. There are no instructions to read other system files, environment secrets, or to exfiltrate data to unexpected endpoints.
Install Mechanism
No install spec (instruction-only) and no network downloads, which is low risk. However the included Python script requires third-party packages ('requests' and Pillow) that are not declared in the metadata or SKILL.md; the skill will fail or raise import errors unless those are installed.
Credentials
No environment variables or credentials are required. The script hardcodes API_KEY='helloworld' (the documented free test key) which matches the SKILL.md. If a user wants to use a private paid key they would need to change the script or add a mechanism to supply it.
Persistence & Privilege
Skill is not always-enabled, does not request persistent platform-wide privileges, and does not modify other skills or global agent settings.
