+
+# OpenCode
+
+Run [OpenCode](https://opencode.ai) AI coding assistant in your workspace for intelligent code generation, analysis, and development assistance. This module integrates with [AgentAPI](https://github.com/coder/agentapi) for seamless task reporting in the Coder UI.
+
+```tf
+module "opencode" {
+  source   = "registry.coder.com/coder-labs/opencode/coder"
+  version  = "0.1.0"
+  agent_id = coder_agent.example.id
+  workdir  = "/home/coder/project"
+}
+```
+
+## Prerequisites
+
+- **Authentication credentials** - OpenCode auth.json file is required while running tasks, you can find this file on your system: `$HOME/.local/share/opencode/auth.json`
+
+## Examples
+
+### Basic Usage with Tasks
+
+```tf
+resource "coder_ai_task" "task" {
+  app_id = module.opencode.task_app_id
+}
+
+module "opencode" {
+  source   = "registry.coder.com/coder-labs/opencode/coder"
+  version  = "0.1.0"
+  agent_id = coder_agent.example.id
+  workdir  = "/home/coder/project"
+
+  ai_prompt = coder_ai_task.task.prompt
+  model     = "anthropic/claude-sonnet-4-20250514"
+
+  # Authentication (required for tasks)
+  auth_json = <<-EOT
+{
+  "google": {
+    "type": "api",
+    "key": "gem-xxx-xxxx"
+  },
+  "anthropic": {
+    "type": "api",
+    "key": "sk-ant-api03-xxx-xxxxxxx"
+  }
+}
+EOT
+
+  mcp                = <<-EOT
+  {
+  "$schema": "https://opencode.ai/config.json",
+  "mcp": {
+    "test-mcp": {
+      "type": "local",
+      "command": [
+        "uv",
+        "--directory",
+        "/Users/jkmr/Documents/work/test-mcp",
+        "run",
+        "test-mcp.py"
+      ],
+      "enabled": true,
+      "environment": {
+        "a": "A"
+      }
+    }
+  }
+}
+EOT
+  pre_install_script = <<-EOT
+  cd test-mcp
+  curl -LsSf https://astral.sh/uv/install.sh | sh
+  source "$HOME"/.bashrc
+  /home/coder/.local/bin/uv sync
+EOT
+}
+```
+
+### Standalone CLI Mode
+
+Run OpenCode as a command-line tool without web interface or task reporting:
+
+```tf
+module "opencode" {
+  source       = "registry.coder.com/coder-labs/opencode/coder"
+  version      = "0.1.0"
+  agent_id     = coder_agent.example.id
+  workdir      = "/home/coder"
+  report_tasks = false
+  cli_app      = true
+}
+```
+
+## Troubleshooting
+
+If you encounter any issues, check the log files in the `~/.opencode-module` directory within your workspace for detailed information.
