A tool for reading and extracting text from images, such as screenshots, scanned documents, and photographs, using optical character recognition (OCR).

Use it to digitize text from PNG, JPEG, TIFF, BMP, and WebP images, including screenshots and scanned paperwork.

It turns text locked inside an image into searchable and editable text without requiring manual transcription.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.00986
Opus 5	$0.00025	$0.00493
Sonnet 5	$0.00010	$0.00197
Haiku 4.5	$0.00005	$0.00099

Security

Grade B, and why

image-ocr scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/ocr_extract.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Image OCR

Extract text from images using Tesseract OCR via Python.

When to use this skill

User asks to read or extract text from an image
User has a screenshot with text they want to process
User has scanned documents that need text extraction
User wants to digitize text from photos

Scripts overview

Script	Purpose	Dependencies
`ocr_extract.py`	Extract text from images with multiple options	`pytesseract`, `Pillow`

Steps

1. Install dependencies (first time only)

Install the Python packages:

pip install pytesseract Pillow

Install Tesseract OCR engine:

Windows: Download installer from https://github.com/UB-Mannheim/tesseract/wiki
macOS: brew install tesseract
Linux (Ubuntu/Debian): sudo apt install tesseract-ocr
Linux (Fedora): sudo dnf install tesseract

For additional language support:

Windows: Select languages during installation
Linux: sudo apt install tesseract-ocr-chi-sim (Chinese Simplified), tesseract-ocr-jpn (Japanese), etc.

CRITICAL — Dependency Error Recovery: If the script fails with an ImportError or "tesseract not found" error, install the missing dependencies using the commands above, then re-run the EXACT SAME script command that failed.

2. Extract text from an image

python scripts/ocr_extract.py "IMAGE_PATH"

Options:

--lang LANG — OCR language (default: eng). Use chi_sim for Chinese, jpn for Japanese, eng+chi_sim for multiple.
--save OUTPUT_PATH — Save extracted text to a file
--preprocess MODE — Image preprocessing: none (default), grayscale, threshold, blur
--dpi DPI — Set image DPI for better accuracy (default: auto-detect)
--psm MODE — Tesseract page segmentation mode (0-13, default: 3 = auto)

Examples:

# Basic text extraction
python scripts/ocr_extract.py "screenshot.png"

# Chinese text extraction
python scripts/ocr_extract.py "document.jpg" --lang chi_sim

# Mixed English and Chinese
python scripts/ocr_extract.py "mixed.png" --lang eng+chi_sim

# Preprocess noisy image for better accuracy
python scripts/ocr_extract.py "noisy_scan.png" --preprocess threshold

# Save output to file
python scripts/ocr_extract.py "scan.tiff" --save output.txt

# Single line of text (e.g., license plate, serial number)
python scripts/ocr_extract.py "plate.jpg" --psm 7

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

image-ocr is a skill published in the GitHub repository AIDotNet/OpenCowork (634 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 986 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
