PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
High-level	PR is incomplete without image file The PR is incomplete as it only adds a template.json file for a new sample without the necessary corresponding image file, rendering the sample unusable. The suggestion is to add the missing image to the samples/sample99 directory. Examples: samples/sample99/template.json [1-17] { "bubbleDimensions": [30, 30], "preProcessors": [ { "name": "CropPage", "options": {"morphKernel": [10, 10]} } ], "fieldBlocks": { "Roll_Number": { ... (clipped 7 lines) Solution Walkthrough: Before: # Directory structure in the PR samples/ └── sample99/ └── template.json After: # Expected directory structure after applying the suggestion samples/ └── sample99/ ├── template.json └── corresponding_image.jpg Suggestion importance[1-10]: 10 __ Why: This suggestion correctly identifies a critical omission; the PR is unusable without the corresponding image file, failing to meet its primary objective.
