OpenCode Orchestrator

Autonomous Multi-Agent Orchestration Engine for Software Engineering

Overview

OpenCode Orchestrator is a framework designed to manage complex software engineering tasks through parallel multi-agent execution. It extends the capabilities of standard AI agents by introducing a hierarchical delegation model and a multi-stage verification pipeline.

Key Characteristics

Parallel Execution: Manages multiple concurrent agent sessions to accelerate development.
Hierarchical Delegation: Supports recursive task decomposition (Fractal Spawning) for complex requirements.
Integrated Verification: Employs a multi-stage pipeline (Unit & Integration) to ensure code quality.
Persistent State: Uses structured logging to maintain state and recover from interruptions.

⚡ Quick Start

npm install -g opencode-orchestrator

In an OpenCode environment:

/task "Implement a real-time collaborative editor using WebSocket"

🏗️ Architecture

The system is built upon two core mechanisms that handle scaling and quality control.

HPFA (Hyper-Parallel Fractal Architecture)

HPFA is a parallel execution model that enables task decomposition at scale.

Managed Concurrency: Orchestrates up to 50 parallel agent sessions simultaneously.
Recursive Scaling: Allows "Worker" agents to spawn sub-workers for modular tasks, ensuring deep architectural coverage.

MSVP (Multi-Stage Verification Pipeline)

MSVP is a structured verification process that decouples implementation from quality assurance.

Stage 1 (Unit Verification): Reviewers validate individual module changes and run local tests immediately after implementation.
Stage 2 (Integration Review): A master reviewer verifies cross-module consistency and system integrity after all individual units are completed.

🚀 System Roles

Role	Responsibility	Key Actions
Commander	Mission Control	Task assignment, conflict resolution, global synchronization
Planner	Architecture	Environment analysis, dependency mapping, TODO generation
Worker	Implementation	Code writing, file modification, unit test creation
Reviewer	Quality Control	Static analysis, build verification, integration testing

🛠️ Features

Concurrent Task Management: Efficiently handles up to 50 background agent sessions.
Automated Context Synthesis: Parallel scouters gather environment intelligence (Structure, Stack, Docs) instantly.
Synchronized Verification: Ensures all distributed tasks pass Stage 1 review before final integration.
Fault Tolerance: Automatically resumes progress from checkpoints in case of tool or session failure.
Context Optimization: Monitors context window limits and performs automated compaction for long sessions.

Piano Developer's Note

OpenCode Orchestrator was developed to solve the "sequential bottleneck" in AI-assisted coding. By treating agents as distributed processing units rather than just chat interfaces, we aim to provide a more reliable and scalable autonomous engineering experience.
