    Multi-Agent Shared Knowledge Graph Builder

    Example session with this skill installed

    Design a knowledge graph schema for a team of 3 agents: a researcher, a writer, and a fact-checker. They need to share findings about pharmaceutical clinical trials.

    • Read your context and instructions
    • Compiled the multi-agent shared knowledge

    I have designed the multi-agent knowledge graph architecture for your clinical trial research team. The design focuses on high-confidence relationship extraction and strict provenance to support the fact-checker agent's validation workflow.

    Clinical Trial Knowledge Graph Architecture

    ComponentSpecification
    Node TypesTrial, Drug, Company, Result, AdverseEvent, Source
    Edge TypesSPONSORED_BY, TESTS_DRUG, REPORTED_IN, INDICATES_EFFICACY
    Agent ScopesResearcher (Write/Read), Writer (Read), Fact-Checker (Validate/Update)
    Primary KeysNCT ID (Trials), CAS Registry Number (Drugs), ROR ID (Companies)
    Trust PolicyFacts remain 'Proposed' until Fact-Checker sets status to 'Validated'

    Entity Extraction Logic

    
    # Extraction pipeline for clinical trial entities
    class TrialExtractionSchema(BaseModel):
        nct_id: str = Field(description="Unique identifier from ClinicalTrials.gov")
        phase: str
        enrollment: int
        primary_endpoint: str
        confidence_score: float
        source_ref: str
    
    # Logic for entity resolution
    def resolve_company(name: str, ror_id: Optional[str]):
        # Prevent merging on name similarity alone
        if ror_id:
            return find_node_by_id(ror_id)
        return find_candidate_by_alias(name)
    

    Next steps

    1. Select a graph backend (Neo4j for complex traversals or AWS Neptune for scale).
    2. Define the 'Validation' trigger for the Fact-Checker agent to transition nodes from 'Proposed' to 'Validated'.
    3. Implement the scoping middleware to ensure the Writer agent only reads 'Validated' facts.

    Connects securely to your tools. The creator never sees your data.

    About this skill

    Managing shared context across multiple AI agents often leads to data collisions, hallucinated relationships, and identity fragmentation. When agents lack a unified source of truth, they repeat work or overwrite each other's progress. This skill provides the architectural framework to build a multi-agent shared knowledge graph that maintains strict provenance, entity resolution, and access control.

    What it does

    • Schema Design defines a canonical ontology for nodes and edges to prevent structural drift.
    • Entity Resolution implements logic to merge aliases and prevent duplicate nodes for the same entity.
    • Provenance Tracking attaches agent identity, timestamps, and confidence scores to every claim.
    • Conflict Resolution detects and manages contradictory facts proposed by different agents.
    • Scoped Retrieval enforces tenant-level isolation and permission filters during graph traversals.

    How it works

    1. Define requirements by mapping agent roles, read/write permissions, and shared vs. private domains.
    2. Design the ontology including node types, relationship cardinality, and temporal properties.
    3. Build the pipeline for entity extraction, normalization, and validation against the schema.
    4. Implement governance to handle concurrent updates, idempotent writes, and truth policies.

    Frameworks & tools

    This tool is agnostic to specific graph databases but provides scaffolding compatible with Neo4j, AWS Neptune, and LangGraph. It focuses on the logic layer between the agent framework and the storage engine.

    Why this beats prompting it yourself

    Generic prompts fail to handle the complexity of entity disambiguation and transactional integrity in a multi-agent environment. This skill provides a systematic engineering framework that treats graph contributions as auditable claims rather than raw text injections.

    Use cases

    • Research Swarms coordinating findings from multiple sources into a single map.
    • Customer Support agents sharing a unified view of user history and product entities.
    • Workflow State management for long-running processes involving different specialist agents.

    Known limitations

    This skill provides architecture and code scaffolding but does not provision physical database instances or live hosting. Implementation quality depends on the underlying graph database capabilities.

    Does not provision database infrastructure. Logic depends on user-supplied storage constraints and agent framework APIs. High-impact merges may still require human-in-the-loop review.

    How to use

    1. 1

      Connect your agent to the Agensi MCP

      Copy the prompt and paste it into Claude, ChatGPT, Cursor or any agent that supports MCP. It sets up the connection for you. Manual setup

    2. 2

      Sign in to Agensi

      Your agent shows a sign-in link. Sign in and click Allow.

    3. 3

      Ask for what you need

      Your agent loads this skill and uses it on your task. It always asks before any payment.

    Frequently Asked Questions

    This skill provides the logic layer and code scaffolding to prevent data collisions and identity fragmentation when multiple agents write to or read from a shared database. It ensures that different agents recognize the same entity as one node rather than creating duplicate or contradictory records.

    The skill is framework-agnostic and designed to sit between your orchestration layer (like LangChain or LangGraph) and your storage engine. It provides the architectural patterns needed to work with Neo4j, AWS Neptune, or any graph database supporting Cypher or Gremlin.

    You will receive the architectural blueprints, schema design templates, and the implementation code for entity resolution and provenance tracking. Please note that it does not include database hosting or pre-provisioned cloud instances.

    Yes, the framework includes a scoped retrieval layer that allows you to define tenant-level isolation and specific read/write permissions for different agent roles within the same graph.

    Unlike raw prompting, this skill treats every agent contribution as an 'auditable claim' with a confidence score and timestamp. It uses systematic logic to validate these claims against your schema before they are committed to the graph, preventing hallucinated relationships.
