Test Suite

This skill includes a comprehensive test suite. Test fixtures use mock credentials that are NOT real secrets:

# All tokens in tests/ are fake placeholders:
MOCK_API_KEY = 'sk-test-1234567890abcdef1234567890abcdef'
MOCK_AWS_KEY = 'AKIAIOSFODNN7EXAMPLE'

IG Cropper

This skill provides a surgical tool to extract pure photographs from Instagram mobile screenshots (dark mode).

How it Works

Adaptive Extraction: Instagram's dark mode uses a very specific background color: RGB (12, 15, 20). The tool scans the screenshot row by row, identifying the interface elements by this color signature and isolating the largest continuous block of non-background imagery—the photograph itself. It extracts this frame flawlessly, regardless of how much the user has scrolled.

Usage

Run the Python script directly on any Instagram screenshot:

python3 scripts/ig_crop.py input_screenshot.png output_pure_photo.png

Philosophy

This tool intentionally does not attempt to algorithmically paint over watermarks or icons located inside the photograph (like pagination numbers or tagged-people indicators). We leave the integrity of the architectural textures untouched, delegating complex restorations to professional generative tools or manual human craftsmanship.

Dependencies

Python 3
Pillow (pip install pillow)
