grits-cli 2.2.3

# Grits

A Git-native, local-first issue tracker with a **Twin Engine** architecture:        
- 🤖 **Agent Engine**: MCP server + agent-native CLI (inspect, workon, pulse, refactor)
- 👀 **Visual Engine**: VS Code extension with 3D topology visualization

**Status**: v2.0.0 — "Solid Graph Command Center"

## Quick Start

### Prerequisites
- Rust (latest stable)
- Git
- Node.js 18+ (for VS Code extension)

### Install CLI

```bash
# Via Cargo (recommended)
cargo install grits-cli

# Or download binary from Releases
# https://github.com/babybirdprd/grits/releases
```

### Initialize a Project
```bash
cd your-project
gr onboard
```

## v2.0 Highlights

### 🚀 Agent-Native Commands

```bash
# Session hydration - get project context instantly
gr pulse

# One-shot context for any target
gr inspect gr-abc123   # Issue
gr inspect src/main.rs # File

# Start working (creates branch + sets status + outputs context)
gr workon gr-abc123

# Fuzzy shorthand updates  
gr set gr-abc pri:1 stat:ip +l:urgent

# Auto-fix dependency cycles
gr refactor --apply --cycle 0
```

### 🔬 Solid Graph Topology

```bash
# Build topology cache (Tree-sitter: Rust, TS, JS, Python, Go)
gr analysis rebuild

# Compute Solid Score (architectural health metric)
gr stats --topology

# Detect and auto-fix cycles
gr refactor                    # Show cycles + suggestions
gr refactor --apply --cycle 0  # Apply fix
gr refactor --undo --target f  # Restore from backup
```

| Feature | Description |
|---------|-------------|
| **Betti Numbers** | B₀=components, B₁=cycles, B₂=voids |
| **Solid Score** | Unified health metric (0-100%) |
| **Edge Persistence** | Identify weakest links in cycles |
| **Star Neighborhoods** | Context loading for AI editing |
| **Monorepo Support** | Cargo, pnpm, turbo, go.work detection |

### 📺 VS Code Dashboard

The extension opens as a **full Webview Panel** with:

- **3D Topology View**: React Three Fiber visualization with orbit controls
- **Vitals Dashboard**: Solid Score gauge, Spaghetti Meter, PageRank hotspots
- **List/Kanban/Graph**: Standard issue management
- **Gutter Decorations**: Issue indicators in editor margins

## Twin Engine Architecture

### 🔗 Tethered Sync
- **SQLite** (`.grits/grits.db`) — Fast local queries
- **JSONL** (`.grits/issues.jsonl`) — Git-versioned, human-readable
- All commands auto-sync between engines

### 🤖 Agent Engine (MCP Server)

```bash
gr serve-mcp
```

**Antigravity Config** (`.vscode/mcp.json`):
```json
{
    "servers": {
        "grits": {
            "command": "gr",
            "args": ["serve-mcp"],
            "env": { "GRITS_PROJECT_ROOT": "${workspaceFolder}" }
        }
    }
}
```

**16 MCP Tools:**
| Category | Tools |
|----------|-------|
| CRUD | `list_issues`, `create_issue`, `update_issue`, `close_issue`, `get_issue` |
| Search | `search_issues`, `find_related_issues`, `detect_duplicates` |
| Strategic | `get_next_task`, `summarize_sprint`, `cleanup_stale` |
| Context | `suggest_issue_for_error`, `infer_issue_from_diff` |
