Changelog Narrator

This skill compares two versions of a business document and produces a structured, human-readable changelog — without git, CLI, or "Track Changes". Designed for non-technical users who receive updated drafts and need to understand what changed at a glance.

Input:

• Two local files (.md or .txt) in the Cowork workspace — old version (v1) and new version (v2)
• Optional: version labels if filenames are ambiguous; optional focus area (e.g., "only compare Section 3")

Output:

• Markdown changelog: Summary → Added → Removed → Modified → Notes

Language Detection

Detect the user's language from their message:

• If Russian (or contains Cyrillic): respond in Russian
• If English (or other Latin-script language): respond in English
• If ambiguous: respond in the language of the trigger phrase used
