## 🛠️ Core Capabilities



### 🔒 Atomic MVCC State Synchronization

The engine solves the "Concurrent TODO Update" problem using **Multi-Version Concurrency Control (MVCC) + Mutex**. Agents can safely mark tasks as complete in parallel without data loss or race conditions. Every state change is cryptographically hashed and logged for a complete audit trail.



### 🧩 Advanced Hook Orchestration

Execution flows are governed by a **Priority-Phase Hook Registry**. Hooks (Safety, UI, Protocol) are grouped into phases (`early`, `normal`, `late`) and executed using a **Topological Sort** to handle complex dependencies automatically, ensuring a predictable and stable environment.



### 🛡️ 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 using server-side compaction triggered by health monitors. This ensures that previous task context (old error messages, stale file references) never leaks into new tasks, maintaining 100% implementation integrity.



### 🚀 Zero-Payload Turbo Mode

Leverages `system.transform` to unshift massive agent instruction sets on the server side. This reduces initial message payloads by **90%+**, slashing latency and preventing context fragmentation during long autonomous loops.



---



## 🛠️ Infrastructure & Reliability



### 🔒 Resource Safety & Reliability

- **RAII Pattern (ConcurrencyToken)**: Guaranteed resource cleanup with zero leaks

- **ShutdownManager**: Priority-based graceful shutdown with 5-second timeout per handler

- **Automatic Backups**: All config changes backed up with rollback support

- **Atomic File Operations**: Temp file + rename for corruption-proof writes

- **Finally Blocks**: Guaranteed cleanup in all critical paths

- **Zero Resource Leaks**: File watchers, event listeners, concurrency slots all properly released



### ⚡ Performance Optimizations

- **Work-Stealing Queues**: Chase-Lev deque implementation for 90%+ CPU utilization

  - Planner: 2 workers, Worker: 8 workers, Reviewer: 4 workers

  - LIFO for owner (cache locality), FIFO for thieves (fairness)

- **Memory Pooling**: 80% GC pressure reduction

  - Object Pool: 200 ParallelTask instances (50 prewarmed)

  - String Interning: Deduplication for agent names, status strings

  - Buffer Pool: Reusable ArrayBuffers (1KB, 4KB, 16KB, 64KB)

- **Session Reuse**: 90% faster session creation (500ms → 50ms)

  - Pool size: 5 sessions per agent type

  - Max reuse: 10 times per session

  - Health check: Every 60 seconds

- **Rust Connection Pool**: 10x faster tool calls (50-100ms → 5-10ms)

  - Max 4 persistent processes

  - 30-second idle timeout

- **Adaptive Polling**: Dynamic 500ms-5s intervals based on system load



### 🛡️ 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 (depth limit enforcement)

- **Auto-Scaling**: Concurrency slots adjust based on success/failure rate

## 🛠️ Key Innovations



### 🧠 Hierarchical Memory System

Maintains focus across thousands of conversation turns using a 4-tier memory structure and **EMA-based Context Gating** to preserve "Architectural Truth" while pruning operational noise.



###  Dynamic Concurrency Auto-Scaling

Slots for parallel implementation scale up automatically after a **3-success streak** and scale down aggressively upon detection of API instability or implementation failures.



### 🛡️ Neuro-Symbolic Safety

Combines LLM reasoning with deterministic **AST/LSP verification**. Every code change is verified by native system tools before being accepted into the master roadmap.



### 🔄 Adaptive Intelligence Loop

- **Stagnation Detection**: Automatically senses when no progress is made across multiple iterations

- **Diagnostic Intervention**: Forces the agent into a "Diagnostic Mode" when stagnation is detected, mandating log audits and strategy pivots

- **Proactive Agency**: Mandates Speculative Planning and Parallel Thinking during background task execution



### 📊 Native TUI Integration

Seamless integration with OpenCode's native TUI via **TaskToastManager**. Provides non-intrusive, real-time feedback on **Mission Progress**, active **Agent Sub-sessions**, and **Technical Metrics** using protocol-safe Toast notifications.



### ⚡ Event-Driven Architecture

Utilizes a hybrid event-driven pipeline (`EventHandler` + `TaskPoller`) to maximize responsiveness while maintaining robust state tracking and resource cleanup.



### 🔒 Secure Configuration

Runtime agent configuration is strictly validated using **Zod schemas**, ensuring that custom agent definitions in `agents.json` are type-safe and error-free before execution.
