SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Raw notes pile up into an unnavigable folder over time. This Skill turns a knowledge directory into a structured second brain by creating encyclopedic wiki pages, distilling recurring lessons, and maintaining domain index hubs that route every query to the right notes. ## Core Features & Use Cases - Wiki pages: Creates encyclopedic stub pages on first mention of a concept and enriches them incrementally with cited facts, never overwriting history. - Lessons distillation: Synthesizes durable patterns and anti-patterns from 3+ sources, decisions, and ingested documents into reusable knowledge notes. - Curator with domain hubs: Maintains Map-of-Content index notes per domain, updates them incrementally on every capture, and runs weekly sweeps to detect orphans, near-duplicates, stale pages, and clusters needing new hubs. - Use Case: After weeks of meeting notes mentioning "chargebee" and "pricing-tiers", ask to consolidate learnings and the Skill produces cited wiki pages, a lesson on pricing patterns, and an updated domain hub linking everything together. ## Quick Start Ask the assistant to build a wiki page on a topic or curate the knowledge base, for example: create a wiki page on our onboarding process and update the knowledge index.

Frequently Asked Questions about knowledge-build

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a personal knowledge base from meeting notes?▼

Capture notes through your normal workflow and let the Skill create wiki stubs on first mention of each concept, then enrich them with cited facts over time. Domain hubs index everything automatically so the knowledge base stays navigable as it grows.

How to distill lessons learned from project decisions?▼

The lessons mode scans for topics recurring across 3 or more meetings, documents, or decisions and drafts a synthesis note with cited evidence. Reversed decisions are treated as the richest lesson sources, and auto-created lessons are flagged for human review.

Does this work with Obsidian vaults and Markdown notes?▼

Yes, it operates entirely on plain Markdown files with YAML frontmatter and wikilinks in an Obsidian-compatible vault. All notes use standard types like wiki, knowledge, doc, and index, so they remain browsable and editable in Obsidian.

What is a Map of Content or domain hub in a knowledge base?▼

A domain hub is an index note that lists every wiki page, lesson, and source document tagged with a matching domain field. The curator updates hubs incrementally on each capture and rebuilds them during weekly sweeps, so navigation stays current without manual effort.

When should I not use automated knowledge base curation?▼

Do not use it when you want a direct answer to a question rather than a synthesis, since querying is handled by a recall workflow instead. It also never auto-creates hubs or merges duplicates without preview and confirmation, so fully hands-off automation is intentionally limited.
