Harmonist Orchestrator 🤖🎼

Transform your LLM agent swarms from cacophony to symphony. Harmonist is not just another agent framework—it's a conductorship engine for AI multi-agent systems, designed to turn independent LLM nodes into a collaborative intelligence orchestra.

🌟 Why Harmonist?

Imagine a jazz ensemble where each musician plays magnificently—but without a conductor, without a shared score, and without listening to one another. That's the state of most multi-agent systems today.

Harmonist is the baton, the sheet music, and the acoustically-tuned concert hall rolled into one. It's a principled orchestration layer that ensures every agent knows when to speak, what to listen to, and how to harmonize with others—without drowning out the collective melody.

This is not a wrapper. This is a constitutional architecture for emergent agent collaboration.

🏗️ Architectural Pillars

📋 Example Profile Configuration

Every Harmonist deployment begins with a profile score—a YAML configuration that defines your agentic ensemble:

orchestra_name: "customer_support_quartet"
conductor:
  model: "claude-3-opus-2026"
  temperature: 0.3
  tempo: "adaptive"  # allegro, andante, or adaptive

instruments:
  - agent_id: "empathy_agent"
    model: "gpt-4o-2026-05-13"
    voice: "compassionate"
    range: "emotional_intelligence"
    prompt: "You are a support agent who validates feelings before solving problems."
    
  - agent_id: "technical_agent"
    model: "claude-3-sonnet-2026"
    voice: "precise"
    range: "troubleshooting"
    prompt: "You are a technical specialist. Provide step-by-step solutions. Cite documentation."
    
  - agent_id: "escalation_agent"
    model: "gpt-4-turbo-2026"
    voice: "formal"
    range: "complex_triage"
    prompt: "You determine if an issue requires human intervention or can be auto-resolved."
    
  - agent_id: "summarizer_agent"
    model: "claude-3-haiku-2026"
    voice: "concise"
    range: "comprehension"
    prompt: "After resolution, produce a 3-sentence summary for the customer's records."

harmony_rules:
  - when: "empathy_agent.confidence < 0.7"
    then: "technical_agent takes lead"
  - when: "escalation_agent.score > 0.85"
    then: "pause all agents → trigger human handoff protocol"

🎯 Example Console Invocation

harmonist conduct --profile customer_support_quartet.yaml \
                  --query "My premium subscription was charged twice this month" \
                  --format text \
                  --verbose \
                  --max-rounds 3

Expected output:

🎼 Harmonist Conductor v2.1.0
⏱️  Tempo: Adaptive
🎻 Ensemble: empathy_agent → technical_agent → escalation_agent → summarizer_agent

[Empathy Agent] 🫂 "I understand how frustrating double charges can be. Let me look into this immediately."
[Technical Agent] 🔧 "Checking billing ID #4829... Found: duplicate charge from session timeout. Refund initiated."
[Escalation Agent] ⚖️ "Confidence: 0.92. Auto-resolving. Sending confirmation to billing@example.com."
[Summarizer Agent] 📝 "Your duplicate charge has been identified and a full refund is being processed. You will receive a confirmation email within 2 hours."

✅ Harmonized Response (2.4s):
"Hi there! I completely understand your concern about the double charge. 
I've investigated and found it was caused by a session timeout during payment processing. 
A full refund is now being processed. You'll receive a confirmation email within 2 hours.

If you have any other questions, please reach out anytime. We're here to help."

💻 OS Compatibility Table

Note: Windows ARM64 is in beta as of Q4 2026. macOS Intel (pre-M1) is supported but performance may vary.

🎛️ Feature List

🧠 Core Intelligence

• Adaptive Conductor Protocol — Automatically adjusts agent call order based on query complexity
• Cascading Confidence — Agents can yield to higher-confidence peers without human intervention
• Temporal Batching — Groups related sub-tasks into single LLM calls for cost efficiency
• Resonance Decay — Automatically forgets stale context to prevent hallucination drift

🌐 Connectivity & Extensibility

• OpenAI API Integration — GPT-4o, GPT-4-turbo (2026 models), o3-mini
• Claude API Integration — Claude Opus, Sonnet, Haiku (2026 editions)
• Plugin Architecture — Bring your own agent, model, or tool via simple Python decorators
• Webhook Callouts — Trigger external systems when an agent reaches a decision

🖥️ Responsive UI

• Web Dashboard — Real-time agent activity visualization (built with FastAPI + HTMX)
• Terminal UI — TUI mode for headless server environments (uses Textual)
• Mobile Responsive — Monitor your orchestra from any device via progressive web app

🌍 Multilingual Support

• 47 languages supported out-of-the-box via auto-detection
• Per-agent language policies (e.g., empathy agent responds in user's native tongue, even if technical agent uses English)
• Unicode normalization and bidirectional text handling for Arabic and Hebrew

🕒 24/7 Customer Support

• Self-Healing Agents — If an agent crashes, the conductor reassigns its tasks within 500ms
• Graceful Degradation — If your API key quota is exhausted, agents enter "read-only advice mode" rather than failing silently
• Live Human Handoff — Seamless transfer to a human operator with full conversation context when confidence drops below threshold

🔒 Enterprise-Grade Security

• End-to-End Encryption for inter-agent communication
• Audit Trails — Every agent decision logged with cryptographic integrity
• Role-Based Access Control — Define who can view, edit, or deploy agent profiles
• SOC 2 Type II Compliant (as of June 2026 audit)

⚙️ API Integrations

OpenAI API (2026 Models)

from harmonist import Conductor

conductor = Conductor(
    api_type="openai",
    api_key="sk-...",  # store in environment variable in production
    models=["o3-mini-2026", "gpt-4o-2026-05-13"],
    temperature_range=(0.1, 0.7)  # agents can self-select temperature
)

result = conductor.process("Analyze our Q3 sales data and suggest improvements")

Claude API (2026 Models)

from harmonist import Conductor

conductor = Conductor(
    api_type="anthropic",
    api_key="sk-ant-...",  # store in environment variable in production
    models=["claude-3-opus-2026", "claude-3-sonnet-2026"],
    extended_thinking=True  # leverages Claude's extended reasoning
)

result = conductor.process("Draft a 5-year strategic roadmap for renewable energy")

Pro Tip: You can mix models from both providers in a single profile. Harmonist handles the serialization differences transparently.

⚠️ Disclaimer

Harmonist Orchestrator is a tool designed to augment human decision-making, not replace it. While our conductor protocol includes guardrails and conflict resolution mechanisms, no AI system is infallible.

• Critical decisions (medical, legal, financial, life-safety) should always involve human review.
• Bias mitigation is an ongoing process. We provide tools for fairness auditing, but ultimate responsibility rests with the operator.
• API costs are the user's responsibility. Harmonist does not charge for the orchestration layer itself, but underlying API calls incur provider fees.
• Data sovereignty — By default, Harmonist processes data in-memory. If using cloud-hosted LLMs, review their data handling policies.

Harmonist is provided "as is," without warranty of any kind. The conductor is your copilot, not your captain.
