    Example session with this skill installed

    I'm uploading 3 notes about 'Vector Databases'. Can you audit them for duplicates, suggest a consistent frontmatter schema, and create a hub note to connect them?

    • Read your context and instructions
    • Compiled the second brain obsidian
    • Generated the document

    I have analyzed the provided notes: Vector_DB_Basics.md, Pinecone_Setup.md, and Milvus_vs_Weaviate.md. There is significant overlap between the Basics note and the comparison note regarding indexing strategies.

    Obsidian Vault Audit & Hub Proposal

    Metadata Schema Recommendation

    To keep your vector database research consistent, I recommend the following YAML frontmatter:

    title: Vector Databases
type: resource/research
status: active
tags:
  - machine-learning
  - databases
  - infrastructure
updated: 2024-05-20

    Proposed Hub Note: [[Vector Databases MOC]]

    
# Vector Databases MOC

## Overview
A Map of Content covering architecture, implementation, and comparisons of vector search engines.

## Foundational Knowledge
- [[Vector_DB_Basics]] — Core concepts of embeddings and similarity search.

## Implementations
- [[Pinecone_Setup]] — Managed service configuration and API usage.
- [[Milvus_vs_Weaviate]] — Comparison of open-source self-hosted options.

## Potential Connections
- Check [[LLM Ops]] for deployment patterns.
- Connect to [[RAG Architecture]] for retrieval flows.

    Next steps

    1. Create the Vector Databases MOC.md file with the content above.
    2. Update the frontmatter in the three source notes for better Dataview compatibility.
    3. Move HNSW technical details from the comparison note to the basics note to reduce redundancy.

    About this skill

    The problem

    Building a personal knowledge base is easy, but maintaining it is hard. Most Obsidian vaults eventually become a graveyard of disconnected Markdown files, broken Wikilinks, and inconsistent metadata that makes retrieval impossible.

    What it does

    • Analyzes vault structure to identify orphan notes, duplicate concepts, and missing Wikilink connections.
    • Generates structured notes with valid YAML frontmatter following existing vault conventions.
    • Creates Maps of Content (MOCs) and hub notes to organize sprawling topics without forcing rigid folder hierarchies.
    • Refactors messy notes by improving Markdown hierarchy and normalizing tags while preserving original content.
    • Synthesizes answers from supplied vault files, citing specific note paths and identifying knowledge gaps.

    Frameworks & tools

    Obsidian, Markdown, YAML Frontmatter, Wikilinks.

    Why this beats prompting it yourself

    Generic LLMs often hallucinate note links or ignore your specific metadata schema. This skill is hard-coded to respect Obsidian-native conventions like Wikilinks and frontmatter standards, ensuring every suggestion is a valid, reversible edit that fits your existing workflow.

    Use cases

    • Perform a vault audit to find and link orphan notes.
    • Convert a raw web clip into a structured permanent note with relevant metadata.
    • Generate a Map of Content for a complex research topic using existing notes.
    • Standardize tagging and frontmatter across a collection of project files.

    Known limitations

    Cannot access local vault files directly without an authorized integration or manual file uploads. Link validation is limited to the context provided in the current session.
