Multi-Agent Knowledge Management
Table of content
A single AI agent doing knowledge management runs into walls fast. It can’t ingest content while simultaneously synthesizing insights. Its context fills up processing one day’s notes. It lacks the specialized skills needed for different knowledge tasks.
Multi-agent systems solve this by dividing work across specialized agents that collaborate through defined patterns.
Why Multiple Agents
Single-agent PKM forces tradeoffs. Your agent is either good at quick capture or deep analysis, not both. It either stays focused on your current task or handles background processing.
| Single Agent | Multi-Agent |
|---|---|
| Context overload on large tasks | Each agent gets focused context |
| One model for everything | Best model per task type |
| Sequential processing | Parallel execution |
| Generalist prompts | Specialized roles |
| Manual triggers | Automated workflows |
Jinyoung Kim’s AI4PKM demonstrates this in practice. His system runs hourly maintenance agents, daily ingestion agents, and weekly synthesis agents, each optimized for its specific job.
Architecture Patterns
Three patterns dominate multi-agent PKM systems. Pick based on your workflow needs.
Orchestrator Pattern
One agent coordinates all others. It receives requests, routes them to specialists, and merges results.
┌─────────────┐
│ Orchestrator│
└──────┬──────┘
┌───────────┼───────────┐
▼ ▼ ▼
┌────────┐ ┌────────┐ ┌────────┐
│ Ingest │ │ Process│ │Synthesize│
└────────┘ └────────┘ └────────┘
The orchestrator handles task decomposition, agent selection, and result aggregation. CrewAI’s hierarchical process implements this with a manager agent that delegates to crew members.
Use when:
- Tasks vary in complexity
- Different requests need different agent combinations
- You want unified entry point
Pipeline Pattern
Agents pass output sequentially. Each stage transforms content for the next.
┌────────┐ ┌────────┐ ┌────────┐ ┌────────┐
│ Capture│ ─► │ Enrich │ ─► │ Connect│ ─► │ Store │
└────────┘ └────────┘ └────────┘ └────────┘
AI4PKM’s Daily Ingestion workflow uses this pattern: extract metadata, convert formats, add summaries and tags, link to existing notes, update indexes.
Use when:
- Processing follows predictable stages
- Each stage’s output feeds the next
- Order matters
Swarm Pattern
Agents work independently and merge results. No central coordinator.
┌────────┐ ┌────────┐ ┌────────┐
│ Agent A│ │ Agent B│ │ Agent C│
└────┬───┘ └────┬───┘ └────┬───┘
└───────────┼───────────┘
▼
┌───────────┐
│ Combine │
└───────────┘
Use when:
- Tasks are independent
- Speed matters more than coordination
- Different perspectives add value
See Subagent Patterns for detailed dispatch strategies.
The Orchestrator’s Job
In hierarchical systems, the orchestrator does real work.
| Responsibility | Implementation |
|---|---|
| Task decomposition | Break user request into subtasks |
| Agent selection | Match subtask to specialist capability |
| Context distribution | Send each agent only relevant context |
| Result merging | Combine outputs coherently |
| Error recovery | Retry or reroute failed tasks |
| Progress tracking | Monitor completion across agents |
The orchestrator itself shouldn’t do knowledge work. It coordinates. Think manager, not worker.
PKM Pipeline Example
A practical daily knowledge pipeline:
┌──────────────────────────────────────────────────────────────┐
│ DAILY PIPELINE │
├──────────────────────────────────────────────────────────────┤
│ │
│ ┌─────────┐ ┌─────────┐ ┌─────────┐ ┌─────────┐ │
│ │ Ingest │ → │ Process │ → │ Connect │ → │Synthesize│ │
│ └─────────┘ └─────────┘ └─────────┘ └─────────┘ │
│ │ │ │ │ │
│ ▼ ▼ ▼ ▼ │
│ Voice notes Add metadata Link to Generate │
│ Web clips Summarize existing daily │
│ Photos Tag content notes roundup │
│ │
└──────────────────────────────────────────────────────────────┘
Each agent runs independently:
- Ingest Agent: Watches input folders, converts formats, normalizes structure
- Process Agent: Adds summaries, extracts entities, generates tags
- Connect Agent: Finds related notes, updates backlinks, maintains indexes
- Synthesis Agent: Creates daily summaries, spots patterns, suggests connections
AI4PKM schedules these through cron jobs. The agents don’t need human triggers after initial setup.
When Single vs Multi
Not every PKM task needs multiple agents. Single agents handle plenty.
| Task Type | Single Agent | Multi-Agent |
|---|---|---|
| Quick lookup | Works well | Overkill |
| Single note edit | Works well | Overkill |
| Batch processing | Context limits | Handles scale |
| Daily synthesis | Slow | Parallel processing |
| Cross-vault analysis | Struggles | Each agent covers a section |
| Background maintenance | Blocks other work | Runs independently |
Start with single-agent workflows. Add agents when you hit specific limits:
- Context window fills before task completes
- Processing time blocks other work
- Task requires incompatible specializations
Implementation Paths
Framework-Based
Use existing multi-agent frameworks:
- CrewAI for role-based agent teams
- LangGraph for visual workflow design
- AutoGen for conversational agent teams
Custom Pipelines
Build simpler pipelines with scheduled scripts:
# Daily PKM pipeline
0 6 * * * claude --task "ingest" vault/inbox/
0 7 * * * claude --task "process" vault/notes/
0 8 * * * claude --task "connect" vault/
0 9 * * * claude --task "synthesize" vault/ --output daily.md
Hybrid Approach
Combine manual orchestration with automated specialists. You decide what runs; agents do the work.
This matches the delegation principle: keep judgment human, automate execution.
Key Tradeoffs
| Benefit | Cost |
|---|---|
| Parallel processing | More complexity to manage |
| Specialized models | Higher API costs |
| Automated workflows | Setup time |
| Focused contexts | Agent coordination overhead |
Multi-agent systems require upfront investment. They pay off when your knowledge base grows large enough that single-agent processing becomes the bottleneck.
