image-ocr

name

image-ocr

description

Use this skill whenever the user sends an image and you cannot see it directly (e.g., you are running on a non-multimodal model like deepseek-v4-pro). This skill runs Tesseract OCR locally to extract text from images. Use when: the user pastes/sends an image, asks to "read" or "recognize" an image, or asks what's in a picture/screenshot. Also use when the user asks for OCR or text extraction from any image file.

Image OCR

When

The current model cannot process images directly. When the user sends an image, this skill extracts text from it using local Tesseract OCR.

How

Run scripts/ocr_image.py <image_path> with appropriate language and PSM settings:

• Default: chi_sim+eng with PSM 3 (auto page segmentation)
• For screenshots with dense text: PSM 6
• For sparse text (book covers, signs): PSM 11
• English only: --lang eng
• Chinese only: --lang chi_sim

PSM modes

PSM	Description	Best for
3	Fully automatic	General purpose, most screenshots
4	Single column of text	Book pages with variable text sizes
6	Uniform block of text	Dense paragraphs
11	Sparse text	Covers, posters, UI elements

Script location

scripts/ocr_image.py — takes image path, outputs UTF-8 text to stdout.

Notes

• Chinese output may display as garbled text in the bash terminal. Write to a file (stdout -> /tmp/ocr_result.txt) and read it instead.
• Tesseract is installed at C:\Program Files\Tesseract-OCR\tesseract.exe
• Available languages: chi_sim, eng, osd
