OpenCode Enhanced

AI Coding Agent with Parallel Tool Execution

English | 简体中文

---

Note

This is an enhanced fork of OpenCode with significant performance improvements and architectural enhancements.

✨ Key Enhancements

🚀 Parallel Tool Execution Engine

• Resource Lock Manager: Sophisticated shared/exclusive lock system for safe concurrent operations
• Dependency-Aware Scheduling: Intelligent analysis of tool dependencies to maximize parallelism while ensuring data consistency
• Adaptive Concurrency: Dynamic adjustment of parallel tool limits based on execution duration and error rates
• Read Operations Parallelization: Multiple read-only tools (read, grep, list, glob) execute simultaneously, drastically reducing wait times

🔧 Enhanced Tools

• Precise Code Navigation: Jump directly to symbols, functions, classes, or line numbers with 1-based indexing
• Smart Code Editing: Multiple matching strategies (exact, fuzzy, block, regex) with anchorLines constraints
• Safe Edit Modes: dryRun and validateOnly options for risk-free code modifications
• Intelligent Error Recovery: Context-aware suggestions when edits fail (e.g., "Did you mean line X?")
• Tool Result Caching: Automatic caching of read operations to avoid redundant executions

⚡ Performance Optimizations

• Async Lazy Loading: Heavy components (Tree-Sitter parsers) load on-demand for faster startup
• Storage Write Batching: Aggregated state updates reduce I/O overhead
• Optimized Processing Loops: Refactored core engine for smoother execution flow
• Work Queue Integration: Robust background task management with priority scheduling

🎨 UI Improvements

• Streamlined terminal interface with better responsiveness
• Enhanced progress indicators for parallel operations
• Improved error visualization and debugging output
