Build a personal LLM powered knowledge base where you collect raw sources, an LLM compiles them into a structured wiki, and Obsidian serves as your read only IDE. You never edit the wiki manually — the LLM writes everything. Based on Andrej Karpathy's LLM Knowledge Bases setup (April 2026). Folder structure:

Turns any raw capture — forwarded emails, quick notes, meeting transcripts, or recordings — into structured next actions. Extracts and classifies every item, generates draft replies and summaries, creates Epismo tracks for tasks, saves decisions and references as context packs, then routes outputs to the right people and channels.

A "start my day" workflow that aggregates calendar events, open tasks, unread or unanswered emails, and recent notes into a single structured daily brief. Produces prioritized focus areas, suggested time blocks, meeting prep notes, and carry overs from previous days. Works especially well combined with voice capture. When to run: First thing each morning, before your first meeting or focused work block. Integrates well with: Calendar (Google/Outlook), task managers (Todoist, Linear, Epismo), email clients, note taking apps (Obsidian, Notion), and voice to text tools.

This workflow is a reproducible, introduction to Anthropic managed Agent Skills using only the built in document Skills: pptx, xlsx, docx, and pdf, with the hands on focus on pptx, xlsx, and pdf. It follows the official patterns from the Agent Skills Quickstart, Using Agent Skills with the API, and the Skills Introduction Cookbook notebook. The public anthropics/skills repository is also useful as a reference because it includes the document Skills folders and explains that the repo is educational and may not match Claude production behavior exactly. Goal Enable a team to run a shared, low friction Agent Skills intro with official code patterns Produce one .pptx, one .xlsx, and one .pdf file that anyone can open locally Keep the workflow parallelizable so people can split work by track Success criteria 1. skills.list(...) returns the Anthropic managed Skills and shows pptx, xlsx, docx, pdf 2. A shared runner script can create a file and download it through the Files API 3. Outputs are stored in predictable folders and open successfully
