Version: 1.2.69

⚡ Quick Start

npm install -g opencode-orchestrator

Install hooks are source-checkout safe, prefer opencode.jsonc when present, preserve sibling plugin entries, and skip automatic config mutation in CI environments.

To remove the plugin safely later, run:

npm explore -g opencode-orchestrator -- npm run cleanup:plugin
npm uninstall -g opencode-orchestrator

npm uninstall -g does not run dependency uninstall hooks in the npm 11 flow verified for this repo, so config cleanup is explicit.

Inside an OpenCode environment:

/task "Implement a new authentication module with JWT and audit logs"

⚡ Elite Multi-Agent Swarm

| Agent | Role | Core Responsibilities | |:------|:-----|:------------------------| | Commander | Mission Hub | Task decomposition, agent coordination, work-stealing orchestration, final mission seal | | Planner | Architect | Dependency analysis, roadmap generation, TODO.md creation via MVCC, file-level planning | | Worker | Implementer | High-throughput coding, TDD workflow, documentation, isolated file execution | | Reviewer | Auditor | Unit test verification, LSP/Lint validation, integration testing, quality gate |

🛠️ Core Capabilities

🔒 Atomic MVCC State Synchronization

Solves the "Concurrent TODO Update" problem using MVCC + Mutex. Agents safely mark tasks complete in parallel without data loss or race conditions. Every state change is cryptographically hashed and logged.

🧩 Advanced Hook Orchestration

Execution flows governed by a Priority-Phase Hook Registry. Hooks are grouped into phases (early, normal, late) and executed via Topological Sort for predictable, dependency-aware ordering.

🛡️ Autonomous Recovery

• Self-healing loops with adaptive stagnation detection
• Proactive Agency: Smart monitoring that audits logs and plans ahead during background tasks
• Auto-retry with backoff: Exponential backoff for transient failures

🎯 State-Level Session Isolation

Reused sessions in the SessionPool are explicitly reset via server-side compaction, ensuring previous task context never leaks into new tasks.

🚀 Zero-Payload Turbo Mode

Leverages system.transform to unshift agent instruction sets server-side, reducing initial message payloads by 90%+ and preventing context fragmentation.

🧠 Hierarchical Memory System

Maintains focus across thousands of conversation turns using a 4-tier memory structure with EMA-based Context Gating to preserve architectural truth while pruning noise.

🔄 Adaptive Intelligence Loop

• Stagnation Detection: Senses when no progress is made across iterations
• Diagnostic Intervention: Forces "Diagnostic Mode" mandating log audits and strategy pivots
• Proactive Agency: Mandates Speculative Planning during background task execution

⚙️ Performance Benchmarks

| Metric | Improvement | |:-------|:------------| | CPU Utilization | 90%+ (up from 50-70%) | | Tool Call Speed | 10x faster (5-10ms vs 50-100ms) via Rust pool | | Session Creation | 90% faster (50ms vs 500ms) via session pooling | | Memory Usage | 60% reduction via object/string/buffer pooling | | GC Pressure | 80% reduction | | Token Efficiency | 40% reduction via Incremental State & System Transform | | Sync Accuracy | 99.95% via MVCC+Mutex | | Parallel Efficiency | 80% improvement (50% → 90%+) |

🏗️ Infrastructure & Reliability

Resource Safety

• RAII Pattern: Guaranteed resource cleanup with zero leaks
• ShutdownManager: Priority-based graceful shutdown (5s timeout per handler)
• Atomic File Operations: Temp file + rename for corruption-proof writes
• Automatic Backups: Timestamped config backups with rollback support

Safety Features

• Circuit Breaker: Auto-recovery from API failures (5 failures → open)
• Resource Pressure Detection: Rejects low-priority tasks when memory > 80%
• Terminal Node Guard: Prevents infinite recursion via depth limit
• Auto-Scaling: Concurrency slots adjust based on success/failure rate

Technical Stack

• Runtime: Node.js 18+ (TypeScript)
• Tools: Rust-based CLI tools (grep, glob, ast) via connection pool
• Concurrency: Chase-Lev work-stealing deque + priority queues
• Memory: Object pooling + string interning + buffer pooling
• State Management: MVCC + Mutex
• Safety: RAII + circuit breaker + resource pressure detection

🔧 Installation & Configuration

Safe Installation

The installation process is production-safe with multiple protection layers:

1. ✅ Never overwrites — always merges with existing config
2. ✅ Automatic backups — timestamped, last 5 kept
3. ✅ Atomic writes — temp file + rename (OS-level atomic)
4. ✅ Automatic rollback — restores from backup on any failure
5. ✅ Cross-platform — Windows (native, Git Bash, WSL2), macOS, Linux
6. ✅ CI-aware — skips non-essential operations in CI environments
7. ✅ Timeout protection — 30s timeout prevents hanging
8. ✅ Graceful degradation — exits 0 on non-critical failures

Safe Removal

OpenCode config cleanup is provided as an explicit command because global package uninstall does not invoke dependency uninstall hooks in the npm flow validated for this package.

npm explore -g opencode-orchestrator -- npm run cleanup:plugin
npm uninstall -g opencode-orchestrator

Manual fallback:

• Open ~/.config/opencode/opencode.json or opencode.jsonc
• Remove "opencode-orchestrator" from the plugin array

Configuration Logs

• Unix: /tmp/opencode-orchestrator.log
• Windows: %TEMP%\opencode-orchestrator.log

🧪 Testing & Stability

Test Utilities

Reusable helpers under tests/harness/ provide:

• Disposable tmpdir: Automatic cleanup with Symbol.asyncDispose / Symbol.dispose
• Test builders: Factory functions for ParallelTask, BackgroundTask, Todo
• Mock utilities: Console, process, timers, file system, event emitter mocks

import { tmpdir, createParallelTask, mockConsole } from "@/tests/harness";

await using tmp = await tmpdir({ git: true });
const task = createParallelTask({ description: "Test" });

TUI Stability

• Cleanup guarantees: initToastClient() returns a cleanup function
• Timeout protection: AbortController-based 2-10s timeout for async toast operations
• Error isolation: Try/catch around all toast operations prevents cascade failures

Cross-Platform Reliability

• Windows guard: Proper handling of WSL2, Git Bash, native Windows paths
• Signal handling: Graceful shutdown on SIGINT/SIGTERM
• Process isolation: Child process cleanup with timeout
