SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Important concepts, tools, teams, and jargon mentioned in meetings or notes often go undocumented, leaving gaps in your knowledge base. This Skill captures every new concept as a wiki page in your Obsidian vault's 06-knowledge/ folder, with cited sources, so nothing mentioned is ever lost. ## Core Features & Use Cases - Stub Creation: Creates a new wiki page with domain classification, aliases, confidence level, and a source citation the first time a concept is mentioned. - Incremental Enrichment: Appends new cited facts to existing pages under "What we know" and logs every addition in a "Sources" audit trail, never overwriting history. - Hub Routing: Files each page into its domain hub or an Unsorted index so the knowledge base stays organized. - Use Case: During a meeting recap you mention a new tool your team adopted. The Skill creates a wiki stub for that tool, cites the meeting note as the source, and links it into the relevant domain hub. ## Quick Start Ask the assistant to create a wiki page on a concept, for example by saying "wiki on retrieval-augmented generation" after discussing it in a meeting.

FAQPage Schema
How do I create a wiki page for a concept in my Obsidian vault?▼

Say something like "wiki on X" or "what do we know about X, write it down". The Skill searches 06-knowledge/ for an existing page, then either creates a cited stub or enriches the existing page with new sourced facts.

How does the knowledge wiki avoid duplicate pages for the same concept?▼

It runs sb_search on the concept name within 06-knowledge/ before creating anything, treating the same thing under another name as a match. Aliases and acronyms are stored in the page frontmatter to catch future variants.

Does the wiki skill overwrite existing notes when adding new information?▼

No, it is strictly append-only. New facts are appended to the "What we know" section with a dated citation, and each addition is logged in the "Sources" section, preserving the full history of the page.

What happens when a wiki page has no clear domain category?▼

The Skill reads the knowledge domains list from the session brief and picks the best fit. If none applies, the page is assigned the "unsorted" domain and listed in the _INDEX.md Unsorted section for later triage.

Can other skills trigger wiki page creation automatically?▼

Yes. When another skill encounters a wikilink pointing to a missing 06-knowledge/ page, it can invoke this Skill to create the stub. In that case the calling skill handles the commit afterward.
