Subject: [PATCH] fix: correct autoCheckpoint config documentation in
 08-checkpoints (#39)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The autoCheckpoint setting does not exist in Claude Code's settings
schema. Checkpointing is automatic and built-in — every user prompt
creates a checkpoint. Replace the incorrect config example with the
actual cleanupPeriodDays setting, which controls retention period.

Fixes #18

 ## Configuration
 
-You can toggle automatic checkpoints in your settings:
+Checkpoints are a built-in default behavior in Claude Code and do not require any configuration to enable. Every user prompt automatically creates a checkpoint.
+
+The only checkpoint-related setting is `cleanupPeriodDays`, which controls how long sessions and checkpoints are retained:
 
 ```json
 {
-  "autoCheckpoint": true
+  "cleanupPeriodDays": 30
 }
 ```
 
-- `autoCheckpoint`: Enable or disable automatic checkpoint creation on every user prompt (default: `true`)
+- `cleanupPeriodDays`: Number of days to retain session history and checkpoints (default: `30`)
