name: extract-content description: Extract entities and concepts from documents using HAIOS memory system. Use when ingesting new documents, analyzing content structure, or populating the knowledge base. generated: '2026-01-07' last_updated: '2026-01-07T20:49:16'

Extract Content

Extract entities (people, systems, concepts) and concepts (decisions, directives, proposals) from documents using LLM-based extraction.

Requirement Level

MAY use for document ingestion. For storing learnings, SHOULD use ingester_ingest directly instead (simpler path).

When to Use

MAY use when:

• Ingesting new documents into HAIOS memory
• Analyzing document structure and key concepts
• Identifying entities mentioned in specifications
• Populating the knowledge graph

Instructions

Via MCP Tool (Recommended)

Use the extract_content MCP tool:

Copyextract_content(
    file_path="path/to/document.md",
    content="<content of the file>",
    extraction_mode="full"  # or "entities_only", "concepts_only"
)

Via Python (Direct)

Note: haios_etl is deprecated. For most use cases, the MCP tool extract_content above is recommended.

Extraction Types

Entities

• Agent: AI agents, systems, tools
• User: Human actors, roles
• ADR: Architecture Decision Records
• System: Technical systems, services

Concepts

• Decision: Architectural or design decisions
• Directive: Instructions, guidelines
• Proposal: Suggested approaches
• Critique: Objections, concerns

Example Workflow

1. Read document content
2. Call extract_content with the content
3. Review extracted entities and concepts
4. Use ingester_ingest to persist relevant items

Copy# Step 1: Extract
result = extract_content(file_path="docs/ADR/ADR-001.md", content=doc_content)

# Step 2: Store important concepts
ingester_ingest(
    content="Use SQLite for the memory database",
    source_path="docs/ADR/ADR-001.md",
    content_type_hint="techne"
)
