+### Memory System
+
+Persistent memory and session tracking for AI learning across sessions.
+
+> **Bundling Recommendation**: These three modules work together as a complete memory system. 
+> For best results, bundle all three: **tool-memory** (storage), **hooks-memory-capture** (automatic capture), 
+> and **context-memory** (context injection). They pair well with **context-persistent** for full session continuity.
+
+| Module | Description | Repository |
+|--------|-------------|------------|
+| **tool-memory** | Persistent memory with FTS5 search, observation types, session tracking | [amplifier-module-tool-memory](https://github.com/michaeljabbour/amplifier-module-tool-memory) |
+| **context-memory** | Inject relevant memories at session start using progressive disclosure | [amplifier-module-context-memory](https://github.com/michaeljabbour/amplifier-module-context-memory) |
+| **hooks-memory-capture** | Automatic observation capture from tool outputs via tool:post | [amplifier-module-hooks-memory-capture](https://github.com/michaeljabbour/amplifier-module-hooks-memory-capture) |
+| **hooks-event-broadcast** | Relay kernel events to WebSocket/transport for desktop apps | [amplifier-module-hooks-event-broadcast](https://github.com/michaeljabbour/amplifier-module-hooks-event-broadcast) |

+**Memory System Features:**
+- **Observation Types**: bugfix, feature, refactor, change, discovery, decision
+- **Session Tracking**: Track sessions with request/investigated/learned/completed summaries
+- **FTS5 Full-Text Search**: Fast search across all memory content
+- **Progressive Disclosure**: Index view with token estimates, full details on demand
+- **Automatic Capture**: hooks-memory-capture captures learnings from tool outputs
+
 ### Hooks
 
 Extend lifecycle events and observability.
