# Agentic Codebase Memory Manager

A centralized memory store for AI coding agents working on the same project. Features a FastAPI JSON API, CLI interface with git-like commands, and a TUI dashboard for visualizing codebase decisions, implemented features, refactoring history, and architectural choices.

## Overview

Memory Manager allows AI agents to store and retrieve context about a codebase, avoiding duplicate work and enabling better coordination. It provides:

- **Persistent Memory**: Store decisions, features, refactorings, and architectural choices
- **Git-like Versioning**: Commit snapshots of memory state, view history, diff between commits
- **Full-text Search**: Search across all entries with SQLite FTS5
- **REST API**: JSON API for integration with other tools
- **Interactive TUI**: Terminal dashboard for visual exploration
- **CLI Interface**: Git-like commands for scripting and automation

## Features

- ✨ Centralized memory store for AI agents
- 🚀 CLI and JSON API for reading/writing memory entries
- 🔧 TUI dashboard to visualize project memory
- 📝 Git-like interface for memory commits
- 🔍 Search and query memory by context
- 🔗 Integration hooks for popular AI coding tools

API documentation available at `http://localhost:8080/docs` (Swagger UI).

## TUI Dashboard

Launch with `memory tui`. Keybindings:

- `d` - Dashboard screen
- `l` - Memory list screen
- `c` - Commit history screen
- `s` - Search screen
- `q` - Quit

## Configuration

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `MEMORY_DB_PATH` | `.memory/codebase_memory.db` | SQLite database path |
| `MEMORY_API_HOST` | `127.0.0.1` | API server host |
| `MEMORY_API_PORT` | `8080` | API server port |
| `MEMORY_PROJECT_PATH` | `.` | Project root path |
| `AGENT_ID` | `unknown` | Agent identifier |

### Project Config

Optional `.memory/config.toml` in project root:

```toml
[project]
name = "my-project"
db_path = ".memory/codebase_memory.db"

[api]
host = "127.0.0.1"
port = 8080
```

## Architecture

```

### Key Components

- **MemoryService**: CRUD operations for memory entries
- **SearchService**: Full-text search with FTS5
- **CommitService**: Git-like versioning with snapshots and diffs
- **MemoryRepository**: Async SQLAlchemy operations with aiosqlite

## Integration with AI Tools

### Cursor

Add to your Cursor project settings or `.cursor/rules`:

```
Use the Memory Manager API at http://localhost:8080 to:
1. Check existing decisions before making new ones
2. Record significant decisions with: POST /api/memory
3. Search past decisions with: GET /api/memory/search?q=
```

### GitHub Copilot

Create a Copilot extension that calls the Memory Manager API to contextually retrieve relevant past decisions when working on similar code.

### Pre-commit Hook

```bash
#!/bin/bash
# .git/hooks/pre-commit
memory commit --message "Auto-save before commit" 2>/dev/null || true
```
