+# Style Guide: Quota vs. Limit
+
+This guide defines the usage of "quota," "limit," and related terms in
+user-facing interfaces.
+
+## TL;DR
+
+- **`quota`**: The administrative "bucket." Use for settings, billing, and
+  requesting increases. (e.g., "Adjust your storage **quota**.")
+- **`limit`**: The real-time numerical "ceiling." Use for error messages when a
+  user is blocked. (e.g., "You've reached your request **limit**.")
+- **When blocked, combine them:** Explain the **limit** that was hit and the
+  **quota** that is the remedy. (e.g., "You've reached the request **limit** for
+  your developer **quota**.")
+- **Related terms:** Use `usage` for consumption tracking, `restriction` for
+  fixed rules, and `reset` for when a limit refreshes.
+
+---
+
+## Detailed Guidelines
+
+### Definitions
+
+- **Quota is the "what":** It identifies the category of resource being managed
+  (e.g., storage quota, GPU quota, request/prompt quota).
+- **Limit is the "how much":** It defines the numerical boundary.
+
+Use **quota** when referring to the administrative concept or the request for
+more. Use **limit** when discussing the specific point of exhaustion.
+
+### When to use "quota"
+
+Use this term for **account management, billing, and settings.** It describes
+the entitlement the user has purchased or been assigned.
+
+**Examples:**
+
+- **Navigation label:** Quota and usage
+- **Contextual help:** Your **usage quota** is managed by your organization. To
+  request an increase, contact your administrator.
+
+### When to use "limit"
+
+Use this term for **real-time feedback, notifications, and error messages.** It
+identifies the specific wall the user just hit.
+
+**Examples:**
+
+- **Error message:** You’ve reached the 50-request-per-minute **limit**.
+- **Inline warning:** Input exceeds the 32k token **limit**.
+
+### How to use both together
+
+When a user is blocked, combine both terms to explain the **event** (limit) and
+the **remedy** (quota).
+
+**Example:**
+
+- **Heading:** Daily usage limit reached
+- **Body:** You've reached the maximum daily capacity for your developer quota.
+  To continue working today, upgrade your quota.

 ### Session retention
 
-To prevent your history from growing indefinitely, enable automatic cleanup
-policies in your settings.
+By default, Gemini CLI automatically cleans up old session data to prevent your
+history from growing indefinitely. When a session is deleted, Gemini CLI also
+removes all associated data, including implementation plans, task trackers, tool
+outputs, and activity logs.
+
+The default policy is to **retain sessions for 30 days**.
+
+#### Configuration
+
+You can customize these policies using the `/settings` command or by manually
+editing your `settings.json` file:
 
 ```json
 {
   "general": {
     "sessionRetention": {
       "enabled": true,
-      "maxAge": "30d", // Keep sessions for 30 days
-      "maxCount": 50 // Keep the 50 most recent sessions
+      "maxAge": "30d",
+      "maxCount": 50
     }
   }
 }
 ```
 
 - **`enabled`**: (boolean) Master switch for session cleanup. Defaults to
-  `false`.
+  `true`.
 - **`maxAge`**: (string) Duration to keep sessions (for example, "24h", "7d",
-  "4w"). Sessions older than this are deleted.
+  "4w"). Sessions older than this are deleted. Defaults to `"30d"`.
 - **`maxCount`**: (number) Maximum number of sessions to retain. The oldest
-  sessions exceeding this count are deleted.
+  sessions exceeding this count are deleted. Defaults to undefined (unlimited).
 - **`minRetention`**: (string) Minimum retention period (safety limit). Defaults
   to `"1d"`. Sessions newer than this period are never deleted by automatic
   cleanup.
