SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Manually aligning form fields on PDFs is a tedious, error-prone process, especially with varying resolutions and complex legal forms where precision is critical. This Skill automates visual field mapping and ensures pixel-perfect alignment, saving hours of manual adjustment and reducing errors.

Core Features & Use Cases

  • Visual Grid Mapper: Provides a click-and-map interface for precise field placement directly on PDF previews, eliminating guesswork.
  • Percentage-Based Coordinates: Automatically converts pixel clicks to resolution-independent percentages, ensuring fields scale correctly across all devices and viewers.
  • Automated Visual QA (Sentinel): Integrates with Gemini Vision to detect and auto-correct misalignments between mapped fields and the underlying PDF, guaranteeing accuracy.
  • Use Case: You need to map new fields for a California Judicial Council form. You can ask the AI to "Guide me through mapping the 'Petitioner Name' field on page 1 of the FL-320 form using the grid mapper, then run a visual audit."

Quick Start

Map the "Case Number" field on page 1 of the DV-100 form using the visual grid mapper, then run a visual audit to confirm alignment.
