Oh My OpenCode

A “battery-included” plugin for OpenCode that transforms it into a powerful multi-agent orchestration system. Think of it as Ubuntu to OpenCode’s Debian.

What’s Included

Agents (Your AI Team)

Agent	Model	Purpose
Sisyphus	Claude Opus 4.5	Default orchestrator with 32k thinking budget. Plans, delegates, executes with parallel execution
oracle	GPT-5.2	Architecture, code review, strategy (inspired by AmpCode)
librarian	Claude Sonnet 4.5	Multi-repo analysis, doc lookup, implementation examples
explore	Grok	Fast codebase exploration and pattern matching (free & fast)
frontend-ui-ux-engineer	Gemini 3 Pro	UI/UX specialist for beautiful interfaces
document-writer	Gemini 3 Flash	Technical writing expert
multimodal-looker	Gemini 3 Flash	Analyzes PDFs, images, diagrams

Tools & Features

Context Management

• Directory AGENTS.md/README.md Injector - Auto-injects context files when reading, walking from file to project root
• Conditional Rules Injector - Injects rules from .claude/rules/ when conditions match (supports globs, alwaysApply)
• Context Window Monitor - Implements “Context Window Anxiety Management” (warns at 70%+ usage)

Built-in MCPs

• context7 - Official documentation lookup
• websearch_exa - Real-time web search
• grep_app - Ultra-fast code search across public GitHub repos

LSP/AST Tools

• Full LSP integration with refactoring tools (rename, code actions)
• AST-Grep for advanced code searching

Smart Automation

• Keyword Detector - Activates modes based on prompts:
  • ultrawork/ulw - Maximum performance with parallel agents
  • search/find - Maximized search with parallel explore + librarian
  • analyze/investigate - Deep multi-phase expert consultation
• Think Mode - Auto-detects when extended thinking is needed (“ultrathink”)
• Todo Continuation Enforcer - Forces agents to complete all TODOs
• Comment Checker - Reduces excessive LLM comments in code

Stability Features

• Anthropic Auto Compact - Auto-summarizes when hitting token limits
• Session Recovery - Recovers from errors (missing tool results, thinking block issues)
• Empty Task Response Detector - Catches when Task tool returns nothing
• Grep Output Truncator - Dynamically truncates based on context window

Notifications

• Background task completion notifications
• Session idle notifications (macOS, Linux, Windows)
• Auto-update checker

AmpCode/Claude Code Compatibility

• look_at tool ported from AmpCode
• Claude Code compatibility layer

Installation

# Interactive installer  
npx oh-my-opencode  
  
# Or let an LLM agent install it  
# Paste the GitHub URL into a fresh opencode session  

Configuration

Config locations (priority order):

1. .opencode/oh-my-opencode.json (project)
2. ~/.config/opencode/oh-my-opencode.json (user)

Customize Agents

{  
  "agents": {  
    "oracle": {  
      "model": "openai/gpt-4o",  
      "temperature": 0.7,  
      "disable": false  
    }  
  }  
}  

Each agent supports: model, temperature, top_p, prompt, tools, disable, description, mode, color, permission

Disable Agents

{  
  "disabled_agents": ["frontend-ui-ux-engineer", "document-writer"]  
}  

LSP Configuration

{  
  "lsp": {  
    "typescript": {  
      "command": "typescript-language-server --stdio",  
      "extensions": [".ts", ".tsx"]  
    }  
  }  
}  

Key Differentiators

• Multi-model orchestration - Uses the best model for each task
• Aggressive parallel execution - Background agents work simultaneously
• No token bloat - Efficient context management
• Production-tested - Author spent $24,000 in tokens refining it
• Supports existing subscriptions - Works with ChatGPT, Claude, Gemini subscriptions
