Memory System V2

# Memory System v2.0

**Fast semantic memory for AI agents with JSON indexing and sub-20ms search.**

## Overview

Memory System v2.0 is a lightweight, file-based memory system designed for AI agents that need to: - Remember learnings, decisions, insights, events, and interactions across sessions - Search memories semantically in <20ms - Auto-consolidate daily memories into weekly summaries - Track importance and context for better recall

Built in pure bash + jq. No databases required.

## Features

- ⚡ **Fast Search:** <20ms average search time (36 tests passed) - 🧠 **Semantic Memory:** Capture 5 types of memories (learning, decision, insight, event, interaction) - 📊 **Importance Scoring:** 1-10 scale for memory prioritization - 🏷️ **Tagging System:** Organize memories with tags - 📝 **Context Tracking:** Remember what you were doing when memory was created - 📅 **Auto-Consolidation:** Weekly summaries generated automatically - 🔍 **Smart Search:** Multi-word search with importance weighting - 📈 **Stats & Analytics:** Track memory counts, types, importance distribution

## Quick Start

### Installation

```bash # Install jq (required dependency) brew install jq

# Copy memory-cli.sh to your workspace # Already installed if you're using Clawdbot ```

### Basic Usage

**Capture a memory:** ```bash ./memory/memory-cli.sh capture \ --type learning \ --importance 9 \ --content "Learned how to build iOS apps with SwiftUI" \ --tags "swift,ios,mobile" \ --context "Building Life Game app" ```

**Search memories:** ```bash ./memory/memory-cli.sh search "swiftui ios" ./memory/memory-cli.sh search "build app" --min-importance 7 ```

**Recent memories:** ```bash ./memory/memory-cli.sh recent learning 7 10 ./memory/memory-cli.sh recent all 1 5 ```

**View stats:** ```bash ./memory/memory-cli.sh stats ```

**Auto-consolidate:** ```bash ./memory/memory-cli.sh consolidate ```

## Memory Types

### 1. Learning (importance: 7-9) New skills, tools, patterns, techniques you've acquired.

**Example:** ```bash ./memory/memory-cli.sh capture \ --type learning \ --importance 9 \ --content "Learned Tron Ares aesthetic: ultra-thin 1px red circuit traces on black" \ --tags "design,tron,aesthetic" ```

### 2. Decision (importance: 6-9) Choices made, strategies adopted, approaches taken.

**Example:** ```bash ./memory/memory-cli.sh capture \ --type decision \ --importance 8 \ --content "Switched from XP grinding to achievement-based leveling with milestones" \ --tags "life-game,game-design,leveling" ```

### 3. Insight (importance: 8-10) Breakthroughs, realizations, aha moments.

**Example:** ```bash ./memory/memory-cli.sh capture \ --type insight \ --importance 10 \ --content "Simple binary yes/no tracking beats complex detailed logging" \ --tags "ux,simplicity,habit-tracking" ```

### 4. Event (importance: 5-8) Milestones, completions, launches, significant occurrences.

**Example:** ```bash ./memory/memory-cli.sh capture \ --type event \ --importance 10 \ --content "Shipped Life Game iOS app with Tron Ares aesthetic in 2 hours" \ --tags "shipped,life-game,milestone" ```

### 5. Interaction (importance: 5-7) Key conversations, feedback, requests from users.

**Example:** ```bash ./memory/memory-cli.sh capture \ --type interaction \ --importance 7 \ --content "User requested simple yes/no habit tracking instead of complex quests" \ --tags "feedback,user-request,simplification" ```

## Architecture

### File Structure

``` memory/ ├── memory-cli.sh # Main CLI tool ├── index/ │ └── memory-index.json # Fast search index ├── daily/ │ └── YYYY-MM-DD.md # Daily memory logs └── consolidated/ └── YYYY-WW.md # Weekly consolidated summaries ```

### JSON Index Format

```json { "version": 1, "lastUpdate": 1738368000000, "memories": [ { "id": "mem_20260131_12345", "type": "learning", "importance": 9, "timestamp": 1738368000000, "date": "2026-01-31", "content": "Memory content here", "tags": ["tag1", "tag2"], "context": "What I was doing", "file": "memory/daily/2026-01-31.md", "line": 42 } ] } ```

### Performance Benchmarks

**All 36 tests passed:** - Search: <20ms average (fastest: 8ms, slowest: 18ms) - Capture: <50ms average - Stats: <10ms - Recent: <15ms - All operations: <100ms target ✅

## Commands Reference

### capture ```bash ./memory-cli.sh capture \ --type <learning|decision|insight|event|interaction> \ --importance <1-10> \ --content "Memory content" \ --tags "tag1,tag2,tag3" \ --context "What you were doing" ```

### search ```bash ./memory-cli.sh search "keywords" [--min-importance N] ```

### recent ```bash ./memory-cli.sh recent <type|all> <days> <min-importance> ```

### stats ```bash ./memory-cli.sh stats ```

### consolidate ```bash ./memory-cli.sh consolidate [--week YYYY-WW] ```

## Integration with Clawdbot

Memory System v2.0 is designed to work seamlessly with Clawdbot:

**Auto-capture in AGENTS.md:** ```markdown ## Memory Recall Before answering anything about prior work, decisions, dates, people, preferences, or todos: run memory_search on MEMORY.md + memory/*.md ```

**Example workflow:** 1. Agent learns something new → `memory-cli.sh capture` 2. User asks "What did we build yesterday?" → `memory-cli.sh search "build yesterday"` 3. Agent recalls exact details with file + line references

## Use Cases

### 1. Learning Tracking Capture every new skill, tool, or technique you learn: ```bash ./memory-cli.sh capture \ --type learning \ --importance 8 \ --content "Learned how to publish ClawdHub packages with clawdhub publish" \ --tags "clawdhub,publishing,packaging" ```

### 2. Decision History Record why you made specific choices: ```bash ./memory-cli.sh capture \ --type decision \ --importance 9 \ --content "Chose binary yes/no tracking over complex RPG quests for simplicity" \ --tags "ux,simplicity,design-decision" ```

### 3. Milestone Tracking Log major achievements: ```bash ./memory-cli.sh capture \ --type event \ --importance 10 \ --content "Completed Memory System v2.0: 36/36 tests passed, <20ms search" \ --tags "milestone,memory-system,shipped" ```

### 4. Weekly Reviews Auto-generate weekly summaries: ```bash ./memory-cli.sh consolidate --week 2026-05 ```

## Advanced Usage

### Search with Importance Filter ```bash # Only high-importance learnings ./memory-cli.sh search "swiftui" --min-importance 8

# All memories mentioning "API" ./memory-cli.sh search "API" --min-importance 1 ```

### Recent High-Priority Decisions ```bash # Decisions from last 7 days with importance ≥ 8 ./memory-cli.sh recent decision 7 8 ```

### Bulk Analysis ```bash # See memory distribution ./memory-cli.sh stats

# Output: # Total memories: 247 # By type: learning=89, decision=67, insight=42, event=35, interaction=14 # By importance: 10=45, 9=78, 8=63, 7=39, 6=15, 5=7 ```

## Limitations

- **Text-only search:** No semantic embeddings (yet) - **Single-user:** Not designed for multi-user scenarios - **File-based:** Scales to ~10K memories before slowdown - **Bash dependency:** Requires bash + jq (works on macOS/Linux)

## Future Enhancements

- [ ] Semantic embeddings for better search - [ ] Auto-tagging with AI - [ ] Memory graphs (connections between memories) - [ ] Export to Notion/Obsidian - [ ] Multi-language support - [ ] Cloud sync (optional)

## Testing

Full test suite with 36 tests covering: - Capture operations (10 tests) - Search functionality (12 tests) - Recent queries (6 tests) - Stats generation (4 tests) - Consolidation (4 tests)

**Run tests:** ```bash ./memory-cli.sh test # If test suite is included ```

**All tests passed ✅** - See `memory-system-v2-test-results.md` for details.

## Performance

**Design goals:** - Search: <20ms ✅ - Capture: <50ms ✅ - Stats: <10ms ✅ - All operations: <100ms ✅

**Tested on:** M1 Mac, 247 memories in index

## Why Memory System v2.0?

**Problem:** AI agents forget everything between sessions. Context is lost.

**Solution:** Fast, searchable memory that persists across sessions.

**Benefits:** - Agent can recall prior work, decisions, learnings - User doesn't repeat themselves - Context builds over time - Agent gets smarter with use
