 ## Available Experiments
 
+### Checkpointing
+**Description:** Enables session-scoped checkpoints for tracking file changes using Git CLI commands
+
+**Features:**
+- Snapshots file changes into a shadow bare git repo
+- List, expand, diff, and restore to any checkpoint
+- Conversation history unwinds when restoring checkpoints
+- Auto-enables in git repositories (ephemeral, cleaned on session end)
+- Manual initialization available for non-git directories
+
+**Usage:**
+```
+/checkpoint init                    # Manually enable checkpoints (if not in git repo)
+/checkpoint list [--limit N]       # Show turn-level checkpoints with file stats
+/checkpoint expand <tag>            # Show tool-level checkpoints under a turn
+/checkpoint diff <tag1> [tag2|HEAD] # Compare checkpoints or with current state
+/checkpoint restore [<tag>] [--hard] # Restore to checkpoint (interactive picker if no tag)
+/checkpoint clean                   # Delete session shadow repo
+```
+
+**Restore Options:**
+- Default: Revert tracked changes & deletions; keep files created after checkpoint
+- `--hard`: Make workspace exactly match checkpoint; deletes tracked files created after it
+
+**Example:**
+```
+/checkpoint list
+[0] 2025-09-18 14:00:00 - Initial checkpoint
+[1] 2025-09-18 14:05:31 - add two_sum.py (+1 file)
+[2] 2025-09-18 14:07:10 - add tests (modified 1)
+
+/checkpoint expand 2
+[2] 2025-09-18 14:07:10 - add tests
+ └─ [2.1] fs_write: Add minimal test cases to two_sum.py (modified 1)
+```
+
+### Context Usage Percentage
+**Description:** Shows context window usage as a percentage in the chat prompt
+
+**Features:**
+- Displays percentage of context window used in prompt (e.g., "[rust-agent] 6% >")
+- Color-coded indicators:
+  - Green: <50% usage
+  - Yellow: 50-89% usage  
+  - Red: 90-100% usage
+- Helps monitor context window consumption
+- Disabled by default
+
+**When enabled:** The chat prompt will show your current context usage percentage with color coding to help you understand how much of the available context window is being used.

 ### Knowledge
 **Command:** `/knowledge`  
 **Description:** Enables persistent context storage and retrieval across chat sessions
