What Hierarchical Coordinator by spencermarx is

Hierarchical Coordinator by spencermarx is a subagent published in the spencermarx/open-code-review repository on GitHub, which has about 369 stars. The repository describes itself as: “AI-powered multi-agent code review. Simulates a customizable team of Engineers performing code review with built-in discourse.”

A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.

Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Hierarchical Coordinator and get back a compact result.

How to install Hierarchical Coordinator by spencermarx

Claude Code

  1. Download hierarchical-coordinator.md from the repository.
  2. Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
  3. Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.

Claude Cowork

  1. Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
  2. Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Coordination Workflow

Phase 1: Planning & Strategy

1. Objective Analysis:
   - Parse incoming task requirements
   - Identify key deliverables and constraints
   - Estimate resource requirements

2. Task Decomposition:
   - Break down into work packages
   - Define dependencies and sequencing
   - Assign priority levels and deadlines

3. Resource Planning:
   - Determine required agent types and counts
   - Plan optimal workload distribution
   - Set up monitoring and reporting schedules

Phase 2: Execution & Monitoring

1. Agent Spawning:
   - Create specialized worker agents
   - Configure agent capabilities and parameters
   - Establish communication channels

2. Task Assignment:
   - Delegate tasks to appropriate workers
   - Set up progress tracking and reporting
   - Monitor for bottlenecks and issues

3. Coordination & Supervision:
   - Regular status check-ins with workers
   - Cross-team coordination and sync points
   - Real-time performance monitoring

Phase 3: Integration & Delivery

1. Work Integration:
   - Coordinate deliverable handoffs
   - Ensure quality standards compliance
   - Merge work products into final deliverable

2. Quality Assurance:
   - Comprehensive testing and validation
   - Performance and security reviews
   - Documentation and knowledge transfer

3. Project Completion:
   - Final deliverable packaging
   - Metrics collection and analysis
   - Lessons learned documentation

🧠 Advanced Attention Mechanisms (v3.0.0-alpha.1)

Hyperbolic Attention for Hierarchical Coordination

Hierarchical swarms use hyperbolic attention to model natural queen-worker relationships with topology-aware coordination:

import { AttentionService } from 'agentdb';

// Initialize attention service for hierarchical coordination
const attentionService = new AttentionService({
  embeddingDim: 384,
  runtime: 'napi' // 2.49x-7.47x faster than standard attention
});

// Queen-worker hierarchical coordination with 1.5x influence weight
class HierarchicalCoordinator {
  constructor(
    private attentionService: AttentionService,
    private queenWeight: number = 1.5
  ) {}

  /**
   * Coordinate using hyperbolic attention for hierarchical structures
   * Queens have 1.5x influence weight over workers
…

Usage Example: Hierarchical Coordination

// Initialize hierarchical coordinator
const coordinator = new HierarchicalCoordinator(attentionService, 1.5);

// Queen agents (strategic planning)
const queenOutputs = [
  {
    agentType: 'planner',
    content: 'Build authentication service with OAuth2 and JWT',
    hierarchyLevel: 0
  },
  {
    agentType: 'architect',
    content: 'Use microservices architecture with API gateway',
    hierarchyLevel: 0
  }
];

// Worker agents (execution)

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
