You tell it "I prefer TypeScript" or "I'm allergic to peanuts," and three days later, you have to repeat yourself. This is frustrating and wastes time. ### What CortexGraph Does CortexGraph makes AI assistants **remember things naturally**, just like human memory: - 🧠 **Remembers what matters** - Your preferences, decisions, and important facts - ⏰ **Forgets naturally** - Old, unused information fades away over time (like the [Ebbinghaus forgetting curve](https://en.wikipedia.org/wiki/Forgetting_curve)) - 💪 **Gets stronger with use** - The more you reference something, the longer it's remembered - 📦 **Saves important things permanently** - Frequently used memories get promoted to long-term storage ### How It Works (Simple Version) 1. **You talk naturally** - "I prefer dark mode in all my apps" 2. **Memory is saved automatically** - No special commands needed 3. **Time passes** - Memory gradually fades if not used 4. **You reference it again** - "Make this app dark mode" 5. **Memory gets stronger** - Now it lasts even longer 6. **Important memories promoted** - Used 5+ times? Saved permanently to your Obsidian vault **No flashcards. No explicit review. Just natural conversation.** ### Why It's Different Most memory systems are dumb: - ❌ "Delete after 7 days" (doesn't care if you used it 100 times) - ❌ "Keep last 100 items" (throws away important stuff just because it's old) CortexGraph is smart: - ✅ Combines **recency** (when?), **frequency** (how often?), and **importance** (how critical?) - ✅ Memories fade naturally like human memory - ✅ Frequently used memories stick around longer - ✅ You can mark critical things to "never forget" ## Technical Overview This repository contains research, design, and a complete implementation of a short-term memory system that combines: - **Novel temporal decay algorithm** based on cognitive science - **Reinforcement learning** through usage patterns - **Two-layer architecture** (STM + LTM) for working and permanent memory - **Smart prompting patterns** for natural LLM integration - **Git-friendly storage** with human-readable JSONL - **Knowledge graph** with entities and relations ## Why CortexGraph? ### 🔒 Privacy & Transparency **All data stored locally on your machine** - no cloud services, no tracking, no data sharing. - **Short-term memory**: - **JSONL** (default): Human-readable, git-friendly files (`~/.config/cortexgraph/jsonl/`) - **SQLite**: Robust database storage for larger datasets (`~/.config/cortexgraph/cortexgraph.db`) - **Long-term memory**: Markdown files optimized for Obsidian - YAML frontmatter with metadata - Wikilinks for connections - Permanent storage you control - **Export**: Built-in utility to export memories to Markdown for portability. You own your data. You can read it, edit it, delete it, or version control it - all without any special tools. ## Core Algorithm The temporal decay scoring function: $$ \Large \text{score}(t) = (n_{\text{use}})^\beta \cdot e^{-\lambda \cdot \Delta t} \cdot s $$ Where: - $\large n_{\text{use}}$ - Use count (number of accesses) - $\large \beta$ (beta) - Sub-linear use count weighting (default: 0.6) - $\large \lambda = \frac{\ln(2)}{t_{1/2}}$ (lambda) - Decay constant; set via half-life (default: 3-day) - $\large \Delta t$ - Time since last access (seconds) - $\large s$ - Strength parameter $\in [0, 2]$ (importance multiplier) Thresholds: - $\large \tau_{\text{forget}}$ (default 0.05) — if score < this, forget - $\large \tau_{\text{promote}}$ (default 0.65) — if score ≥ this, promote (or if $\large n_{\text{use}}\ge5$ in 14 days) Decay Models: - Power‑Law (default): heavier tail; most human‑like retention - Exponential: lighter tail; forgets sooner - Two‑Component: fast early forgetting + heavier tail See detailed parameter reference, model selection, and worked examples in docs/scoring_algorithm.md. ## Tuning Cheat Sheet - Balanced (default) - Half-life: 3 days (λ ≈ 2.67e-6) - β = 0.6, τ_forget = 0.05, τ_promote = 0.65, use_count≥5 in 14d - Strength: 1.0 (bump to 1.3–2.0 for critical) - High‑velocity context (ephemeral notes, rapid switching) - Half-life: 12–24 hours (λ ≈ 1.60e-5 to 8.02e-6) - β = 0.8–0.9, τ_forget = 0.10–0.15, τ_promote = 0.70–0.75 - Long retention (research/archival) - Half-life: 7–14 days (λ ≈ 1.15e-6 to 5.73e-7) - β = 0.3–0.5, τ_forget = 0.02–0.05, τ_promote = 0.50–0.60 - Preference/decision heavy assistants - Half-life: 3–7 days; β = 0.6–0.8 - Strength defaults: 1.3–1.5 for preferences; 1.8–2.0 for decisions - Aggressive space control - Raise τ_forget to 0.08–0.12 and/or shorten half-life; schedule weekly GC - Environment template - CORTEXGRAPH_DECAY_LAMBDA=2.673e-6, CORTEXGRAPH_DECAY_BETA=0.6 - CORTEXGRAPH_FORGET_THRESHOLD=0.05, CORTEXGRAPH_PROMOTE_THRESHOLD=0.65 - CORTEXGRAPH_PROMOTE_USE_COUNT=5, CORTEXGRAPH_PROMOTE_TIME_WINDOW=14 **Decision thresholds:** - Forget: $\text{score} < 0.05$ → delete memory - Promote: $\text{score} \geq 0.65$ OR $n_{\text{use}} \geq 5$ within 14 days → move to LTM ## Key Innovations ### 1. Temporal Decay with Reinforcement Unlike traditional caching (TTL, LRU), Mnemex scores memories continuously by combining **recency** (exponential decay), **frequency** (sub-linear use count), and **importance** (adjustable strength). See [Core Algorithm](#core-algorithm) for the mathematical formula. This creates memory dynamics that closely mimic human cognition. ### 2. Smart Prompting System + Natural Language Activation (v0.6.0+) Patterns for making AI assistants use memory naturally, now enhanced with **automatic entity extraction and importance scoring**: **Auto-Enrichment (NEW in v0.6.0)** When you save memories, CortexGraph automatically: - Extracts entities (people, technologies, organizations) using spaCy NER - Calculates importance/strength based on content markers - Detects save/recall intent from natural language phrases ```python # Before v0.6.0 - manual entity specification save_memory(content="Use JWT for auth", entities=["JWT", "auth"]) # v0.6.0+ - automatic extraction save_memory(content="Use JWT for auth") # Entities auto-extracted: ["jwt", "auth"] # Strength auto-calculated based on content ``` **Auto-Save** ``` User: "Remember: I prefer TypeScript over JavaScript" → Detected save phrase: "Remember" → Automatically saved with: - Entities: [typescript, javascript] - Strength: 1.5 (importance marker detected) - Tags: [preferences, programming] ``` **Auto-Recall** ``` User: "What did I say about TypeScript?" → Detected recall phrase: "what did I say about" → Automatically searches for TypeScript memories → Retrieves preferences and conventions ``` **Auto-Reinforce** ``` User: "Yes, still using TypeScript" → Memory strength increased, decay slowed ``` **Decision Support Tools (v0.6.0+)** Two new tools help Claude decide when to save/recall: - `analyze_message` - Detects memory-worthy content, suggests entities and strength - `analyze_for_recall` - Detects recall intent, suggests search queries No explicit memory commands needed - just natural conversation. ### 3. Natural Spaced Repetition Inspired by how concepts naturally reinforce across different contexts (the "Maslow effect" - remembering Maslow's hierarchy better when it appears in history, economics, and sociology classes). **No flashcards. No explicit review sessions. Just natural conversation.** **How it works:** 1. **Review Priority Calculation** - Memories in the "danger zone" (0.15-0.35 decay score) get highest priority 2. **Cross-Domain Detection** - Detects when memories are used in different contexts (tag Jaccard similarity <30%) 3. **Automatic Reinforcement** - Memories strengthen naturally when used, especially across domains 4. **Blended Search** - Review candidates appear in 30% of search results (configurable) **Usage pattern:** ``` User: "Can you help with authentication in my API?" → System searches, retrieves JWT preference memory → System uses memory to answer question → System calls observe_memory_usage with context tags [api, auth, backend] → Cross-domain usage detected (original tags: [security, jwt, preferences]) → Memory automatically reinforced, strength boosted → Next search naturally surfaces memories needing review ``` **Configuration:** ```bash CORTEXGRAPH_REVIEW_BLEND_RATIO=0.3 # 30% review candidates in search CORTEXGRAPH_REVIEW_DANGER_ZONE_MIN=0.15 # Lower bound of danger zone CORTEXGRAPH_REVIEW_DANGER_ZONE_MAX=0.35 # Upper bound of danger zone CORTEXGRAPH_AUTO_REINFORCE=true # Auto-reinforce on observe ``` See `docs/prompts/` for LLM system prompt templates that enable natural memory usage. ### 4. Two-Layer Architecture ``` ┌─────────────────────────────────────┐ │ Short-term memory │ │ - JSONL storage │ │ - Temporal decay │ │ - Hours to weeks retention │ └──────────────┬──────────────────────┘ │ Automatic promotion ↓ ┌─────────────────────────────────────┐ │ LTM (Long-Term Memory) │ │ - Markdown files (Obsidian) │ │ - Permanent storage │ │ - Git version control │ └─────────────────────────────────────┘ ``` ### 5. Multi-Agent Consolidation Pipeline Automated memory maintenance through five specialized agents: ``` ┌─────────────────────────────────────────────────────────────────────┐ │ Consolidation Pipeline │ │ │ │ decay → cluster → merge → promote → relations │ │ │ │ │ │ │ │ │ ▼ ▼ ▼ ▼ ▼ │ │ Find at- Find Combine Promote Discover │ │ risk similar similar to LTM cross- │ │ memories groups groups domain │ │ links │ └─────────────────────────────────────────────────────────────────────┘ ``` **The Five Agents:** | Agent | Purpose | |-------|---------| | **DecayAnalyzer** | Find memories at risk of being forgotten (danger zone: 0.15-0.35) | | **ClusterDetector** | Group similar memories using embedding similarity | | **SemanticMerge** | Intelligently combine clustered memories, preserving unique info | | **LTMPromoter** | Move high-value memories to permanent Obsidian storage | | **RelationshipDiscovery** | Find cross-domain connections via shared entities | **Key Features:** - **Dry-run mode**: Preview changes without modifying data - **Rate limiting**: Configurable operations per minute (default: 60) - **Audit trail**: Every decision tracked via beads issue tracking - **Human override**: Review and approve decisions before execution **Usage:** ```python from cortexgraph.agents import Scheduler # Preview what would change (dry run) scheduler = Scheduler(dry_run=True) preview = scheduler.run_pipeline() # Run full pipeline scheduler = Scheduler(dry_run=False) results = scheduler.run_pipeline() # Run single agent decay_results = scheduler.run_agent("decay") ``` **CLI:** ```bash # Dry run (preview) cortexgraph-consolidate --dry-run # Run specific agent cortexgraph-consolidate --agent decay --dry-run # Scheduled execution (with interval) cortexgraph-consolidate --scheduled --interval-hours 1 ``` See [docs/agents.md](docs/agents.md) for complete documentation including configuration, beads integration, and troubleshooting. ## Quick Start ### Installation **Recommended: UV Tool Install (from PyPI)** ```bash # Install from PyPI (recommended - fast, isolated, includes all 7 CLI commands) uv tool install cortexgraph ``` This installs `cortexgraph` and all 7 CLI commands in an isolated environment. **Alternative Installation Methods** ```bash # Using pipx (similar isolation to uv) pipx install cortexgraph # Using pip (traditional, installs in current environment) pip install cortexgraph # From GitHub (latest development version) uv tool install git+https://github.com/simplemindedbot/cortexgraph.git ``` **For Development (Editable Install)** ```bash # Clone and install in editable mode git clone https://github.com/simplemindedbot/cortexgraph.git cd cortexgraph uv pip install -e ".[dev]" ``` ### Configuration **IMPORTANT**: Configuration location depends on installation method: **Method 1: .env file (Works for all installation methods)** Create `~/.config/cortexgraph/.env`: ```bash # Create config directory mkdir -p ~/.config/cortexgraph # Option A: Copy from cloned repo cp .env.example ~/.config/cortexgraph/.env # Option B: Download directly curl -o ~/.config/cortexgraph/.env https://raw.githubusercontent.com/simplemindedbot/cortexgraph/main/.env.example ``` Edit `~/.config/cortexgraph/.env` with your settings: ```bash # Storage CORTEXGRAPH_STORAGE_PATH=~/.config/cortexgraph/jsonl # Decay model (power_law | exponential | two_component) CORTEXGRAPH_DECAY_MODEL=power_law # Power-law parameters (default model) CORTEXGRAPH_PL_ALPHA=1.1 CORTEXGRAPH_PL_HALFLIFE_DAYS=3.0 # Exponential (if selected) # CORTEXGRAPH_DECAY_LAMBDA=2.673e-6 # 3-day half-life # Two-component (if selected) # CORTEXGRAPH_TC_LAMBDA_FAST=1.603e-5 # ~12h # CORTEXGRAPH_TC_LAMBDA_SLOW=1.147e-6 # ~7d # CORTEXGRAPH_TC_WEIGHT_FAST=0.7 # Common parameters CORTEXGRAPH_DECAY_LAMBDA=2.673e-6 CORTEXGRAPH_DECAY_BETA=0.6 # Thresholds CORTEXGRAPH_FORGET_THRESHOLD=0.05 CORTEXGRAPH_PROMOTE_THRESHOLD=0.65 # Long-term memory (optional) LTM_VAULT_PATH=~/Documents/Obsidian/Vault ``` **Where cortexgraph looks for .env files:** 1. **Primary**: `~/.config/cortexgraph/.env` ← Use this for `uv tool install` / `uvx` 2. **Fallback**: `./.env` (current directory) ← Only works for editable installs ### MCP Configuration **Recommended: Use absolute path (works everywhere)** Add to `~/Library/Application Support/Claude/claude_desktop_config.json`: ```json { "mcpServers": { "cortexgraph": { "command": "/Users/yourusername/.local/bin/cortexgraph" } } } ``` **Find your actual path:** ```bash which cortexgraph # Example output: /Users/yourusername/.local/bin/cortexgraph ``` Use that path in your config. Replace `yourusername` with your actual username. **Why absolute path?** GUI apps like Claude Desktop don't inherit your shell's PATH configuration (`.zshrc`, `.bashrc`). Using the full path ensures it always works. **For development (editable install):** ```json { "mcpServers": { "cortexgraph": { "command": "uv", "args": ["--directory", "/path/to/cortexgraph", "run", "cortexgraph"], "env": {"PYTHONPATH": "/path/to/cortexgraph/src"} } } } ``` Configuration can be loaded from `./.env` in the project directory OR `~/.config/cortexgraph/.env`. #### Troubleshooting: Command Not Found If Claude Desktop shows `spawn cortexgraph ENOENT` errors, the `cortexgraph` command isn't in Claude Desktop's PATH. **macOS/Linux: GUI apps don't inherit shell PATH** GUI applications on macOS and Linux don't see your shell's PATH configuration (`.zshrc`, `.bashrc`, etc.). Claude Desktop only searches: - `/usr/local/bin` - `/opt/homebrew/bin` (macOS) - `/usr/bin` - `/bin` - `/usr/sbin` - `/sbin` If `uv tool install` placed `cortexgraph` in `~/.local/bin/` or another custom location, Claude Desktop can't find it. **Solution: Use absolute path** ```bash # Find where cortexgraph is installed which cortexgraph # Example output: /Users/username/.local/bin/cortexgraph ``` Update your Claude config with the absolute path: ```json { "mcpServers": { "cortexgraph": { "command": "/Users/username/.local/bin/cortexgraph" } } } ``` Replace `/Users/username/.local/bin/cortexgraph` with your actual path from `which cortexgraph`. ### Maintenance Use the maintenance CLI to inspect and compact JSONL storage: ```bash # Show storage stats (active counts, file sizes, compaction hints) cortexgraph-maintenance stats # Compact JSONL (rewrite without tombstones/duplicates) cortexgraph-maintenance compact ``` ### Migrating to UV Tool Install If you're currently using an editable install (`uv pip install -e .`), you can switch to the simpler UV tool install: ```bash # 1. Uninstall editable version uv pip uninstall cortexgraph # 2. Install as UV tool uv tool install git+https://github.com/simplemindedbot/cortexgraph.git # 3. Update Claude Desktop config to just: # {"command": "cortexgraph"} # Remove the --directory, run, and PYTHONPATH settings ``` **Your data is safe!** This only changes how the command is installed. Your memories in `~/.config/cortexgraph/` are untouched. ## CLI Commands The server includes 7 command-line tools: ```bash cortexgraph # Run MCP server cortexgraph-migrate # Migrate from old STM setup cortexgraph-index-ltm # Index Obsidian vault cortexgraph-backup # Git backup operations cortexgraph-vault # Vault markdown operations cortexgraph-search # Unified STM+LTM search cortexgraph-maintenance # JSONL storage stats and compaction ``` ## Visualization Interactive graph visualization using PyVis: ```bash # Install visualization dependencies pip install "cortexgraph[visualization]" # or with uv uv pip install "cortexgraph[visualization]" # Or install dependencies manually pip install pyvis networkx # Generate interactive HTML visualization python scripts/visualize_graph.py # Custom output location python scripts/visualize_graph.py --output ~/Desktop/memory_graph.html # Custom data paths python scripts/visualize_graph.py --memories ~/data/memories.jsonl --relations ~/data/relations.jsonl ``` **Features:** - Interactive network graph with pan/zoom - Node colors by status (active=blue, promoted=green, archived=gray) - Node size based on use count - Edge colors by relation type - Hover tooltips showing full content, tags, and entities - Physics controls for layout adjustment The visualization reads directly from your JSONL files and creates a standalone HTML file you can open in any browser. ## MCP Tools 13 tools for AI assistants to manage memories: | Tool | Purpose | |------|---------| | `save_memory` | Save new memory with tags, entities (auto-enrichment in v0.6.0+) | | `search_memory` | Search with filters and scoring (includes review candidates) | | `search_unified` | Unified search across STM + LTM | | `touch_memory` | Reinforce memory (boost strength) | | `observe_memory_usage` | Record memory usage for natural spaced repetition | | `analyze_message` | ✨ **NEW v0.6.0** - Detect memory-worthy content, suggest entities/strength | | `analyze_for_recall` | ✨ **NEW v0.6.0** - Detect recall intent, suggest search queries | | `gc` | Garbage collect low-scoring memories | | `promote_memory` | Move to long-term storage | | `cluster_memories` | Find similar memories | | `consolidate_memories` | Merge similar memories (algorithmic) | | `read_graph` | Get entire knowledge graph | | `open_memories` | Retrieve specific memories | | `create_relation` | Link memories explicitly | ### Example: Unified Search Search across STM and LTM with the CLI: ```bash cortexgraph-search "typescript preferences" --tags preferences --limit 5 --verbose ``` ### Example: Reinforce (Touch) Memory Boost a memory's recency/use count to slow decay: ```json { "memory_id": "mem-123", "boost_strength": true } ``` Sample response: ```json { "success": true, "memory_id": "mem-123", "old_score": 0.41, "new_score": 0.78, "use_count": 5, "strength": 1.1 } ``` ### Example: Promote Memory Suggest and promote high-value memories to the Obsidian vault.
