+
+# Gemini CLI
+
+Run [Gemini CLI](https://ai.google.dev/gemini-api/docs/cli) in your workspace to access Google's Gemini AI models, and custom pre/post install scripts. This module integrates with [AgentAPI](https://github.com/coder/agentapi) for Coder Tasks compatibility.
+
+```tf
+module "gemini" {
+  source           = "registry.coder.com/anomaly/gemini/anomaly"
+  version          = "1.0.0"
+  agent_id         = coder_agent.example.id
+  gemini_api_key   = var.gemini_api_key
+  gemini_model     = "gemini-1.5-pro-latest"
+  install_gemini   = true
+  gemini_version   = "latest"
+  agentapi_version = "latest"
+}
+```
+
+## Prerequisites
+
+- You must add the [Coder Login](https://registry.coder.com/modules/coder-login/coder) module to your template
+- Node.js and npm will be installed automatically if not present
+
+## Usage Example
+
+```tf
+variable "gemini_api_key" {
+  type        = string
+  description = "Gemini API key"
+  sensitive   = true
+}
+
+module "gemini" {
+  count          = data.coder_workspace.me.start_count
+  source         = "registry.coder.com/anomaly/gemini/anomaly"
+  version        = "1.0.0"
+  agent_id       = coder_agent.example.id
+  gemini_api_key = var.gemini_api_key # we recommend providing this parameter inorder to have a smoother experience (i.e. no google sign-in)
+  gemini_model   = "gemini-1.5-pro-latest"
+  install_gemini = true
+  gemini_version = "latest"
+}
+```
+
+## How it Works
+
+- **Install**: The module installs Gemini CLI using npm (installs Node.js if needed)
+- **Configure**: Optionally writes your settings JSON to `~/.gemini/settings.json`
+- **Start**: Launches Gemini CLI in the specified directory, wrapped by AgentAPI
+- **Environment**: Sets `GEMINI_API_KEY`, `GOOGLE_GENAI_USE_VERTEXAI`, `GEMINI_MODEL` for the CLI (if variables provided)
+
+## Troubleshooting
+
+- If Gemini CLI is not found, ensure `install_gemini = true` and your API key is valid
+- Node.js and npm are installed automatically if missing
+- Check logs in `/home/coder/.gemini-module/` for install/start output
+
