OpenCode Agents

AI agent framework for plan-first development workflows with approval-based execution. Multi-language support (TypeScript, Python, Go, Rust) with automatic testing, code review, and validation.

Note: This repository has evolved since the demo video with continuous improvements to make it easier for others to use in their projects. The core concepts remain the same, but installation and component organization have been streamlined.

Why Use This?

• ✅ Multi-language support - Works with TypeScript, Python, Go, Rust, and more
• ✅ Plan-first workflow - Agents propose plans before implementing
• ✅ Incremental execution - Step-by-step implementation with validation
• ✅ Quality built-in - Automatic testing, type checking, and code review
• ✅ Your patterns - Agents follow your coding standards from context files

---

Quick Start

Step 1: Install OpenCode CLI

# Follow official guide
https://opencode.ai/docs

Step 2: Install Agents & Commands

Option A: Interactive Installer (Recommended)

curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash

The installer offers:

• 🎯 Quick Profiles: Core, Developer, Full, or Advanced
• 🎨 Custom Selection: Pick exactly what you need
• 📦 Smart Dependencies: Auto-installs required components
• ✨ Interactive Menus: User-friendly component browser

Option B: Profile-Based Install

# Core essentials only
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s core

# Balanced for daily development
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s developer

# Everything included
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s full

Option C: Manual Install

# Clone this repository
git clone https://github.com/darrenhinde/opencode-agents.git
cd opencode-agents

# Install to OpenCode directory (global)
mkdir -p ~/.opencode
cp -r .opencode/agent ~/.opencode/
cp -r .opencode/command ~/.opencode/
cp -r .opencode/context ~/.opencode/

Step 3: Start Building

# Start the main development agent (recommended for new users)
opencode --agent codebase-agent

# Tell it what to build
> "Create a React todo list with TypeScript"

What happens next:

1. Agent proposes an implementation plan
2. Asks for your approval
3. Implements step-by-step with validation
4. Delegates to @task-manager for complex features
5. Uses @tester and @reviewer for quality assurance

---

How It Works

User Request
    ↓
codebase-agent (main coordinator)
    ↓
    ├─→ @task-manager (breaks down complex features)
    ├─→ @tester (writes and runs tests)
    ├─→ @reviewer (security and code review)
    ├─→ @documentation (generates docs)
    └─→ @build-agent (type checking and validation)

The workflow:

1. You describe what you want to build
2. Agent plans the implementation steps
3. You approve the plan
4. Agent implements incrementally with validation
5. Quality checks run automatically (tests, types, linting)
6. Subagents handle specialized tasks (testing, review, docs)

Context-aware: Agents automatically load patterns from .opencode/context/ to follow your coding standards.

Example Workflows

Build a Feature

opencode --agent codebase-agent
> "Create a user authentication system with email/password"

# Agent will:
# 1. Propose implementation plan
# 2. Wait for your approval
# 3. Delegate to @task-manager (creates tasks/subtasks/user-auth/)
# 4. Implement step-by-step
# 5. Use @tester for tests
# 6. Use @reviewer for security review

Make a Commit

# Make your changes
git add .

# Use the commit command
/commit

# Auto-generates: ✨ feat: add user authentication system

Add Your Patterns

# Edit your project context
nano ~/.opencode/context/project/project-context.md

# Add your patterns:
# **API Endpoint Pattern:**
# ```typescript
# export async function POST(request: Request) {
#   // Your standard pattern
# }
# ```

# Agents will automatically use these patterns!

How It Compares

vs GitHub Copilot

• ✅ Plan-first workflow - Proposes plans before executing (Copilot executes immediately)
• ✅ Approval-based - You review and approve each step (Copilot auto-completes)
• ✅ Multi-agent system - Specialized agents for testing, review, docs (Copilot is single-purpose)
• ✅ Context-aware - Follows your coding patterns from context files

vs Cursor

• ✅ IDE-agnostic - Works with any editor (Cursor is IDE-specific)
• ✅ Multi-agent coordination - Task delegation between specialized agents
• ✅ Workflow orchestration - Manages complex multi-step features
• ✅ Open source - Fully customizable and extensible

vs Aider

• ✅ Visual workflow - Interactive menus and progress tracking (Aider is CLI-only)
• ✅ Subagent system - Automatic delegation to specialized agents
• ✅ Built-in validation - Type checking, testing, and review integrated
• ✅ Installation profiles - Choose your feature set (core, developer, full)

Key Differentiator: OpenCode Agents is the only framework that combines plan-first workflows, approval-based execution, and multi-agent coordination with your custom coding patterns.

Common Questions

Q: What's the main way to use this?
A: Use opencode --agent codebase-agent for development. It coordinates everything else.

Q: Do I need to install plugins/tools?
A: No, they're optional. Only install if you want Telegram notifications or Gemini AI features.

Q: Where should I install - globally or per-project?
A: Global (~/.opencode/) works for most. Project-specific (.opencode/) if you need different configs per project.

Q: How do I add my own coding patterns?
A: Edit ~/.opencode/context/project/project-context.md - agents automatically load this file.

Q: What languages are supported?
A: The agents work with any language (TypeScript, Python, Go, Rust, etc.) and adapt based on your project files.

Q: What's the AGENT-SYSTEM-BLUEPRINT.md for?
A: It's a teaching document explaining architecture patterns and how to extend the system.

Q: Can I use just one command or agent?
A: Yes! Use the installer's list feature to see all components:

./install.sh --list

Or cherry-pick individual files with curl:

curl -o ~/.opencode/agent/codebase-agent.md \
  https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/.opencode/agent/codebase-agent.md

Recommended for New Users

Start with codebase-agent - it's your main development partner that handles planning, implementation, and quality assurance. It automatically delegates to specialized subagents when needed, so you don't have to manage multiple agents yourself.

opencode --agent codebase-agent
> "Your development task here"

The agent will guide you through the entire development workflow with a plan-first, approval-based approach.
