# Knowledge Base Builder

The Knowledge Base Builder skill helps you create, structure, and maintain knowledge bases that AI agents can effectively query and utilize. It transforms scattered information—from project documentation to tribal knowledge—into organized, accessible knowledge that improves AI performance and team productivity.

This skill guides you through knowledge extraction, organization, structuring, and maintenance. It understands different knowledge formats (documentation, code comments, decision logs, schemas), helps you choose appropriate storage (markdown files, knowledge graphs, databases), and ensures knowledge remains current and useful.

Use this skill when starting new projects, onboarding AI to complex systems, preserving institutional knowledge, or improving AI agent effectiveness through better context.

## Core Workflows

### Workflow 1: Build Knowledge Base from Scratch
1. **Define** knowledge base purpose:
   - Who will use it? (AI agents, developers, both)
   - What problems does it solve?
   - What scope/boundaries?
2. **Identify** knowledge sources:
   - Existing documentation
   - Code repositories
   - Team conversations
   - Decision records
   - Tribal knowledge
3. **Extract** relevant information:
   - Key concepts and relationships
   - Architectural decisions
   - Domain terminology
   - Common patterns
   - Troubleshooting knowledge
4. **Structure** the knowledge:
   - Choose organization (hierarchical, graph, hybrid)
   - Define categories/taxonomies
   - Establish relationships
   - Create metadata schema
5. **Format** for consumption:
   - Markdown for documentation
   - Knowledge graph for relationships
   - Schema files for structure
   - Code comments for implementation
6. **Populate** the knowledge base:
   - Create initial content
   - Link related concepts
   - Add examples
   - Include references
7. **Validate** accessibility:
   - Can AI find information?
   - Is context sufficient?
   - Are relationships clear?
8. **Establish** maintenance process

### Workflow 2: Extract Knowledge from Codebase
1. **Analyze** codebase structure:
   - Architecture patterns
   - Module organization
   - Key abstractions
   - Data flow
2. **Identify** extractable knowledge:
   - Design decisions
   - API contracts
   - Data models
   - Business logic
   - Edge cases
3. **Generate** documentation:
   - Architecture overview
   - Component descriptions
   - API reference
   - Data dictionary
   - Integration guides
4. **Create** knowledge graph:
   - Entities (modules, services, models)
   - Relationships (depends on, implements, extends)
   - Observations (purpose, constraints, patterns)
5. **Link** to code:
   - File paths for reference
   - Function signatures
   - Configuration locations
6. **Maintain** synchronization:
   - Update on code changes
   - Version knowledge with code
   - Automate where possible

### Workflow 3: Organize Project Knowledge
1. **Audit** existing knowledge:
   - What documentation exists?
   - What's missing?
   - What's outdated?
   - What's scattered?
2. **Define** structure:
   - Documentation hierarchy
   - File organization
   - Naming conventions
   - Cross-referencing approach
3. **Create** core documents:
   - README.md (overview, getting started)
   - ARCHITECTURE.md (system design)
   - DECISIONS.md (ADRs)
   - PIPELINE_STATUS.md (project state)
   - CONTRIBUTING.md (development guide)
4. **Establish** conventions:
   - Document templates
   - Metadata standards
   - Update procedures
   - Review processes
5. **Populate** with content:
   - Migrate existing docs
   - Fill gaps with new content
   - Link related documents
   - Add navigation
6. **Integrate** with AI:
   - Add to context
   - Create knowledge graph entries
   - Enable discovery
   - Test accessibility

### Workflow 4: Build Knowledge Graph
1. **Identify** entities:
   - What are the key concepts?
   - What needs to be remembered?
   - What has relationships?
2. **Define** entity types:
   - Project (repos, services, apps)
   - Component (modules, features, functions)
   - Person (team members, stakeholders)
   - Decision (architectural choices)
   - Process (workflows, procedures)
   - Resource (docs, tools, dependencies)
3. **Extract** observations:
   - Facts about each entity
   - Properties and attributes
   - Context and purpose
   - Status and state
4. **Map** relationships:
   - How entities connect
   - Relationship types
   - Directionality
   - Strength/importance
5. **Store** in knowledge graph:
   - Use Memory MCP
   - Create entities
   - Create relations
   - Add observations
6. **Query** to validate:
   - Can you find entities?
   - Do relationships make sense?
   - Is information complete?
7. **Maintain** over time:
   - Add new entities
   - Update observations
   - Add new relationships
   - Prune obsolete information

### Workflow 5: Maintain Knowledge Base
1. **Monitor** knowledge health:
   - Usage frequency
   - Outdated content
   - Gaps in coverage
   - User feedback
2. **Update** regularly:
   - Reflect code changes
   - Document new decisions
   - Add new patterns
   - Remove deprecated info
3. **Review** periodically:
   - Quarterly knowledge audit
   - Validate accuracy
   - Check completeness
   - Improve clarity
4. **Optimize** for consumption:
   - Improve searchability
   - Add missing links
   - Consolidate redundancy
   - Enhance examples
5. **Gather** feedback:
   - What's confusing?
   - What's missing?
   - What's most useful?
6. **Iterate** on structure:
   - Reorganize if needed
   - Add new categories
   - Improve navigation
   - Refine metadata

      observations: [
        "Next.js 14+ application",
        "Uses Supabase for backend",
        "Deployed on Vercel",
        "Monorepo structure"
      ]
    },
    {
      name: "authentication-module",
      entityType: "Component",
      observations: [
        "Located in /src/features/auth",
        "Handles user authentication via Supabase Auth",
        "Supports magic link and OAuth",
        "Implements RLS policies"
      ]
    }
  ]
});

// Create relationships
await memory.create_relations({
  relations: [
    {
      from: "id8labs-app",
      to: "authentication-module",
      relationType: "contains"
    },
    {
      from: "authentication-module",
      to: "Supabase Auth",
      relationType: "uses"
    }
  ]
});
```
