 This basic setup will:
 
 - Install Gemini CLI in the workspace
 - Configure authentication with your API key
-- Set Gemini to run in `/home/coder/project` directory
+- Set Gemini to run in `/home/coder` directory
 - Enable interactive use from the terminal
 - Set up MCP server integration for task reporting

+### Session Resumption Behavior
+
+By default, Gemini CLI automatically resumes existing conversations when your workspace restarts. Sessions are tracked per workspace directory, so conversations continue where you left off. If no session exists (first start), your `ai_prompt` will run normally. To disable this behavior and always start fresh, set `continue = false`
+
+## State Persistence
+
+AgentAPI can save and restore its conversation state to disk across workspace restarts. This complements `continue` (which resumes the Gemini CLI session) by also preserving the AgentAPI-level context. Enabled by default, requires agentapi >= v0.12.0 (older versions skip it with a warning).
+
+To disable:
+
+```tf
+module "gemini" {
+  # ... other config
+  enable_state_persistence = false
+}
+```

 ### Using Vertex AI (Enterprise)
 
 For enterprise users who prefer Google's Vertex AI platform:
 
 ```tf
 module "gemini" {
   source         = "registry.coder.com/coder-labs/gemini/coder"
-  version        = "3.0.0"

   gemini_api_key = var.gemini_api_key
-  folder         = "/home/coder/project"
+  folder         = "/home/coder"
   use_vertexai   = true
 }
 ```
