KG Extract

Extract entities (classes, functions, modules, types, concepts) and their relations (imports, extends, implements, depends-on, calls) from source files, then store them as a knowledge graph in AgentDB.

When to use

When you need to build or update a knowledge graph from source code or documentation. Useful for understanding codebase structure, dependency analysis, and impact assessment.

Steps

Scan files -- use
```
Glob
```
and
```
Read
```
to enumerate and read source files at the given path
Identify entities -- extract classes, functions, modules, types, and config references from each file
Map relations -- for each entity, determine its relations to other entities:
- ```
imports
```
  : follow import/require statements
- ```
extends
```
  : class inheritance
- ```
implements
```
  : interface implementations
- ```
depends-on
```
  : constructor dependencies, injected services
- ```
calls
```
  : function/method invocations
- ```
references
```
  : documentation mentions, comments
Store in AgentDB -- call
```
mcp__claude-flow__agentdb_hierarchical-store
```
for each entity with metadata (name, type, file, line, description)
Create edges -- call
```
mcp__claude-flow__agentdb_causal-edge
```
for each relation with source, target, relation type, and weight
Report -- summarize: total entities by type, total relations by type, files scanned

CLI alternative

bash

npx @claude-flow/cli@latest memory store --namespace knowledge-graph --key "entity-NAME" --value "METADATA_JSON"
npx @claude-flow/cli@latest memory search --query "entities in auth module" --namespace knowledge-graph
