Knowledge Graph Rebuilder

Introduction

Night-time knowledge graph reconstruction from daily logs. Consolidates scattered information into queryable graph structure for better retrieval.

Why it matters: Flat logs are hard to query. Graph structure enables relationship discovery and semantic search.

Real-world example: Agent rebuilds knowledge graph nightly, adds new entities and relationships from day's conversations, improves query accuracy.

Skills You Need

Skill	Source	Purpose
memory	ClawdHub	Graph operations
filesystem	Built-in	Log reading

How to Setup

1. Graph Schema

const schema = {
  entities: ['Person', 'Project', 'Concept'],
  relations: ['works_on', 'knows', 'depends_on']
};

2. Rebuild Process

function rebuildGraph() {
  const logs = readDailyLogs();
  const entities = extractEntities(logs);
  const relations = extractRelations(logs);
  return { entities, relations };
}

3. Prompt Template

## Knowledge Graph Rebuilder

Every night:
1. Read today's memory files
2. Extract entities (people, projects, concepts)
3. Identify relationships
4. Merge into knowledge graph
5. Update semantic indices
6. Prune outdated connections

Query capabilities:
- "What projects depend on X?"
- "Who knows about Y?"
- "Related concepts to Z"

Success Metrics

• Graph rebuilt nightly
• Query response time <100ms
• Entity coverage >90%
