Documentation Knowledge Graph - Quick Reference

One-page guide for using the documentation graph system


Import Documentation

from amplihack.memory.neo4j import Neo4jConnector, DocGraphIntegration
from pathlib import Path

# Setup
connector = Neo4jConnector()
connector.connect()
doc_integration = DocGraphIntegration(connector)
doc_integration.initialize_doc_schema()

# Import single file
stats = doc_integration.import_documentation(
    file_path=Path("docs/my_doc.md"),
    project_id="my-project"
)

# Import all files in directory
for doc_path in Path("docs/").glob("**/*.md"):
    doc_integration.import_documentation(doc_path)

# Link documentation to code nodes (from blarify)
link_count = doc_integration.link_docs_to_code()
print(f"Created {link_count} links")

Query Documentation

# Search for relevant docs
results = doc_integration.query_relevant_docs("authentication", limit=5)

for doc in results:
    print(f"{doc['title']}")
    print(f"  Path: {doc['path']}")
    print(f"  Concept matches: {doc['concept_matches']}")

CLI Usage

# Import all markdown files
python scripts/import_docs_to_neo4j.py docs/

# Import with linking
python scripts/import_docs_to_neo4j.py --link-code --link-memory docs/

# Test parsing (no Neo4j needed)
python scripts/test_doc_parsing_standalone.py

Graph Schema

DocFile → HAS_SECTION → Section
DocFile → DEFINES → Concept
DocFile → REFERENCES → CodeFile
Concept → IMPLEMENTED_IN → Function/Class
Memory → DOCUMENTED_IN → DocFile

Extracted Data

From each markdown file:

  • Title: First H1 heading
  • Sections: All headings (H1-H6)
  • Concepts: Headings, bold text, code languages
  • Code refs: @file.py, file:line, inline.py
  • Links: text
  • Metadata: Size, word count, last modified

Example Queries

Find documentation about a topic

docs = doc_integration.query_relevant_docs("neo4j memory")

Get all concepts from a document

MATCH (df:DocFile {path: $path})-[:DEFINES]->(c:Concept)
RETURN c.name, c.category

Find code implementing a concept

MATCH (c:Concept {name: $concept})-[:IMPLEMENTED_IN]->(f:Function)
RETURN f.name, f.file_path

Find documentation referencing specific code

MATCH (df:DocFile)-[r:REFERENCES]->(cf:CodeFile {path: $code_path})
RETURN df.title, df.path

Statistics

# Get graph statistics
stats = doc_integration.get_doc_stats()
print(f"Documents: {stats['doc_count']}")
print(f"Concepts: {stats['concept_count']}")
print(f"Sections: {stats['section_count']}")
print(f"Code refs: {stats['code_ref_count']}")

Code Reference Patterns

The system detects:

@src/file.py → src/file.py
file.py:42 → file.py, line 42
`config.py` → config.py

Integration

With Code Graph (blarify)

# 1. Import code graph
blarify = BlarifyIntegration(connector)
blarify.import_blarify_output(Path("code_graph.json"))

# 2. Import documentation
doc_integration.import_documentation(Path("docs/"))

# 3. Link them
doc_integration.link_docs_to_code()

With Memory System

# Import docs and link to memories
doc_integration.import_documentation(Path("docs/"))
doc_integration.link_docs_to_memories()

Testing

# Full test (requires Neo4j running)
python scripts/test_doc_graph.py

# Parsing only (no Neo4j)
python scripts/test_doc_parsing_standalone.py

Common Patterns

Import all project docs

from pathlib import Path

# Find all markdown files
project_root = Path(".")
doc_files = list(project_root.glob("**/*.md"))

# Import each one
for doc_file in doc_files:
    try:
        stats = doc_integration.import_documentation(doc_file)
        print(f"✓ {doc_file.name}: {stats}")
    except Exception as e:
        print(f"✗ {doc_file.name}: {e}")

Find documentation for current task

def get_relevant_docs(task_description: str) -> List[Dict]:
    """Find documentation relevant to a task."""
    # Extract key terms from task
    key_terms = extract_keywords(task_description)

    # Search for each term
    all_docs = []
    for term in key_terms:
        docs = doc_integration.query_relevant_docs(term, limit=3)
        all_docs.extend(docs)

    # Deduplicate and sort by relevance
    unique_docs = {doc['path']: doc for doc in all_docs}
    return list(unique_docs.values())

Update documentation graph

# Re-import changed files (idempotent)
changed_files = get_changed_markdown_files()

for file_path in changed_files:
    doc_integration.import_documentation(file_path)

# Rebuild links
doc_integration.link_docs_to_code()
doc_integration.link_docs_to_memories()

Performance Tips

  1. Batch imports: Import multiple files in one transaction
  2. Link after import: Import all docs first, then link
  3. Use project_id: Scope queries to specific projects
  4. Cache results: Query results are stable until docs change

Troubleshooting

Neo4j connection fails:

export NEO4J_PASSWORD='your_password'
docker-compose -f docker/docker-compose.neo4j.yml up -d

No concepts extracted:

  • Check markdown has headings
  • Check for bold text (important)
  • Check for code blocks with language

No code links created:

  • Ensure code graph imported first (blarify)
  • Check code references in docs (@file.py)
  • Verify CodeFile nodes exist in Neo4j

Next Steps

After importing documentation:

  1. Test queries: Verify you can find relevant docs
  2. Link to code: Create doc-code relationships
  3. Link to memories: Connect learnings to docs
  4. Use in agents: Provide doc context to agents
