+# Session Memory Optimizer
+
+Optimize Claude Code session performance with health monitoring, context pruning guidance, and checkpoints for long coding sessions.
+
+## Problem Solved
+
+Claude Code experiences performance degradation after 2-5 hours of continuous work:
+- Response times increase
+- Context confusion occurs
+- Pro Max subscribers ($199/mo) get degraded results
+
+This plugin provides proactive session management to prevent degradation.
+
+## Features
+
+### Commands
+- `/session-status` - Display session health metrics and recommendations
+- `/session-checkpoint <name>` - Save current session context as a checkpoint
+- `/session-restore [name]` - Restore context from a checkpoint
+- `/session-optimize` - Analyze context and get pruning recommendations
+
+### Hooks
+- **PreCompact** - Injects optimization guidance when Claude auto-compacts
+- **SessionStart** - Notifies of available checkpoints from previous sessions
+- **SessionEnd** - Auto-saves checkpoint for sessions >30 minutes
+
+### Skills
+- **Context Management** - Best practices for maintaining session performance
+
+## Installation
+
+```bash
+claude plugins add github:ojallington/session-memory-optimizer
+```
+
+## Usage
+
+```bash
+# Check session health
+/session-status
+
+# Save checkpoint before major work
+/session-checkpoint before-refactor
+
+# Get optimization recommendations
+/session-optimize

+# Restore after restart
+/session-restore before-refactor
