# OpenCode Agents ### AI agent framework for plan-first development workflows with approval-based execution [](https://github.com/darrenhinde/opencode-agents/stargazers) [](https://opensource.org/licenses/MIT) [](https://github.com/darrenhinde/opencode-agents/commits/main) [](docs/contributing/CONTRIBUTING.md) [](https://buymeacoffee.com/darrenhinde) **Multi-language support:** TypeScript • Python • Go • Rust **Features:** Automatic testing • Code review • 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.

📹 Following along with the video? The simplified structure shown in the tutorial is available on the video-simple branch.

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

Note: Interactive mode requires downloading the script first (can't run through pipe)

macOS / Linux

# Download the installer
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh -o install.sh

# Run interactively
bash install.sh

Windows (Git Bash)

# Download the installer
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh -o install.sh

# Run interactively
bash install.sh

Windows (PowerShell)

# Download the script
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh" -OutFile "install.sh"

# Run with Git Bash
& "C:\Program Files\Git\bin\bash.exe" install.sh

# Or run with WSL
wsl bash install.sh

Note: Git Bash comes with Git for Windows. Download here

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
• 🛡️ Collision Detection: Safely handles existing files with 4 strategies (skip/overwrite/backup/cancel)
• 🖥️ Cross-Platform: Works on macOS, Linux, and Windows (Git Bash/WSL)

Updating? The installer detects existing files and lets you choose: skip existing (keep your changes), overwrite all (get latest), or backup & overwrite (safe update). Learn more

Option B: Profile-Based Install (Recommended)

Fastest method: One command, no interaction needed

macOS / Linux / Git Bash / WSL

# Core - Minimal essentials (9 components)
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s core

# Developer - Recommended for daily work (22 components)
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s developer

# Full - Everything included (25 components)
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s full

# Advanced - Full + System Builder (30 components)
curl -fsSL https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh | bash -s advanced

Windows PowerShell

# Download script
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/darrenhinde/opencode-agents/main/install.sh" -OutFile "install.sh"

# Core profile
& "C:\Program Files\Git\bin\bash.exe" install.sh core

# Developer profile
& "C:\Program Files\Git\bin\bash.exe" install.sh developer

# Full profile
& "C:\Program Files\Git\bin\bash.exe" install.sh full

# Advanced profile
& "C:\Program Files\Git\bin\bash.exe" install.sh advanced

New! The advanced profile includes the System Builder - an interactive tool that generates complete custom AI systems tailored to your domain. Learn more

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!

Common Questions

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

Q: Does this work on Windows?
A: Yes! Use Git Bash (recommended) or WSL. See Platform Compatibility Guide for details.

Q: What bash version do I need?
A: Bash 3.2+ (works on macOS default bash). Run bash scripts/tests/test-compatibility.sh to check your system.

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 for?
A: It's a teaching document explaining architecture patterns and how to extend the system. See docs/features/agent-system-blueprint.md

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.
