SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It eliminates the difficulty of turning scattered conversation details into an organized, searchable knowledge base that an AI can reliably reference later.

Core Features & Use Cases

  • Lightweight markdown knowledge base: Store books, people, concepts, meetings, ideas, articles, projects, and news as structured .md entries under a brain/ workspace.
  • Proactive ingestion workflow: Check what the conversation mentions, search for existing entries, and create new ones when important information is missing.
  • Cross-referencing with validation rules: Update related entries’ links and enforce required frontmatter fields (title, type, date, tags, summary) and news deduplication using item_id.
  • Use Case: As you discuss a new product idea and a specific author, the skill adds them immediately as entries, links them together, and ensures the news item can be deduplicated over time.

Quick Start

Create a searchable personal knowledge base entry by organizing the attached notes into structured markdown under brain/ with required frontmatter and cross-references.

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

FAQPage Schema
How do I build a markdown knowledge base from conversation content?▼

To build a markdown knowledge base, the skill creates structured `.md` entries under a `brain/` workspace from conversation content. It enforces required YAML frontmatter and applies cross-referencing for books, people, and concepts.

What is proactive knowledge capture and how does it work for personal notes?▼

Proactive knowledge capture checks what a conversation mentions, searches for existing entries, and creates new ones when important information is missing. This ensures your personal notes are automatically updated without manual data entry.

How do I cross-link related markdown notes with YAML frontmatter?▼

Cross-link related markdown notes by updating the `links` field in their YAML frontmatter. The skill enforces required frontmatter fields like title, type, date, tags, and summary while automatically patching links between related entries.

Can I use ripgrep-style full-text search on a personal knowledge graph?▼

Yes, you can perform ripgrep-style full-text search on your personal knowledge graph. The skill maintains a lightweight markdown workspace that supports search behavior to retrieve stored books, people, concepts, and news entries.

How do I deduplicate news entries in a markdown knowledge base?▼

Deduplicate news entries using a strict `item_id` field and validation rules in the YAML frontmatter. This ensures recurring news items are identified and deduplicated over time, preventing duplicate entries in your knowledge base.

Do I need any dependencies to set up a personal knowledge graph?▼

No external dependencies are required to set up this personal knowledge graph. The skill operates independently to create and maintain structured markdown entries with cross-referencing and full-text search capabilities.
