# 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 --- ## Instructions ### Step 1: Identify and Validate Files 1.

Please provide both the old version (v1) and the new version (v2)." - If no files are given: scan the Cowork workspace for `.md` and `.txt` files; list them and ask the user to specify which two to compare 2. Read both files - If a file is unreadable (binary, corrupted, unsupported format): stop — "Could not read [filename]. changelog-narrator works with .md and .txt files only." 3. Determine version order (which is v1, which is v2) - Infer from filename markers:
