// Geoffrey Process Draft - Drafts Action
// Processes a single draft based on routing instructions
//
// Call via URL with JSON in text parameter:
// drafts://x-callback-url/runAction?action=Geoffrey%20Process%20Draft&text={"uuid":"...","destination":"..."}
//
// JSON parameters:
// - uuid: Draft UUID to process
// - destination: "omnifocus", "obsidian", "archive", or "trash"
// - project: OmniFocus project name (for omnifocus destination)
// - tags: Comma-separated OmniFocus tags (for omnifocus destination)
// - dueDate: Due date string (for omnifocus destination)
// - folder: Obsidian folder path (for obsidian destination)
//
// To install:
// 1. Create new action in Drafts named "Geoffrey Process Draft"
// 2. Add a "Script" step
// 3. Paste this code

// Parse parameters from draft content (passed as JSON via URL text parameter)
