Newsletter Digest Builder

This skill takes a folder of saved articles and newsletters (.txt or .md files) and returns a structured weekly digest: articles scored by relevance to your role, grouped by topic, with a "Read This Week" shortlist at the top.

Input:

• A folder path (or list of files) containing .txt/.md articles — one article per file
• Your role or current focus area (stated in 1–2 sentences in your message)

Output:

• Markdown digest with a "Read This Week" shortlist (5–7 items), full list grouped by topic, and a "Can Skip This Week" section

---

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: Validate Input

1. Check that files have been provided (folder path, uploaded files, or pasted list)

   • If no files provided: stop and return — "Please provide a folder path or upload your saved article files (.txt or .md). I need at least 1 article to build a digest."
   • Accepted formats: .txt files, .md files, pasted markdown list

2. Check that the user's role or focus area is stated in their message

   • If missing: ask once before proceeding — "What's your current role or focus area? (e.g., 'PM focused on AI product launches' or 'Marketer working on B2B demand generation')"
   • Do not guess or assign a generic role — prioritization depends on it

3. Validate files: skip empty or unreadable files; note count at end of output

   • If all files are empty or unreadable: stop with — "No readable article files found. Check that files contain article text."

Step 2: Extract Articles

1. For each file, extract:
   • Title: first H1 heading, first bold line, or filename (as fallback)
   • Source domain: from URLs in the file if present (e.g., hbr.org, lenny.substack.com)
   • Body text: first 200–300 words for topic detection and relevance scoring
