**Stop drowning in verbose git/Graphite output.** This plugin automatically enables context-efficient workflows for all git and Graphite CLI operations in Claude Code.

## 🎯 What This Does

Transforms Claude Code's interaction with git/Graphite from context-polluting to context-efficient:

**Before (without plugin):**
```bash
You: "Check my Graphite stack"
Claude: [Returns 15KB of JSON → 4,000+ tokens consumed]
Context: Polluted, reasoning degraded
```

**After (with plugin):**
```bash
You: "Check my Graphite stack"
Claude: [Automatically delegates to Task subagent]
Subagent: [Processes 15KB in isolated context]
Claude: "✓ feature/auth | 3 PRs | Review #456"
Context: Clean, 18 tokens used (225x more efficient)
```

## ✨ Features

- **🔄 Automatic Delegation** - Task subagents handle verbose operations automatically
- **🎨 Colored Agent Support** - Optional custom agent with cyan terminal output
- **⚡ Zero Friction** - SessionStart hook activates patterns automatically
- **📦 Team-Ready** - Git-trackable configuration for team distribution
- **🎯 225x Efficiency** - Dramatic context window improvements
- **🔧 Flexible** - Supports both Task tool (simple) and custom agents (enhanced UX)

## 🚀 Quick Start

### Installation

```bash
# Clone this repository
git clone https://github.com/your-username/carbon.git
cd carbon

# Option 1: Install globally (affects all projects)
./install.sh --global

# Option 2: Install in current project (recommended for teams)
./install.sh --project

# Option 3: Manual installation
mkdir -p .claude/plugins/carbon
cp -r hooks settings.json plugin.json .claude/plugins/carbon/
chmod +x .claude/plugins/carbon/hooks/session-start.sh
```

### Verification

```bash
# Test the installation
./test/verify-installation.sh

# Start Claude Code with debug mode
claude --debug hooks

# Test automatic delegation
claude
> "Check my Graphite stack"
# Should automatically use Task delegation ✓
```

## 🎨 Two Approaches

### Task Tool (Default - Recommended for Most Users)

Zero setup, works immediately:

```bash
You: "Check my stack"
Claude: [Uses Task delegation automatically]
```

**Characteristics:**
- ⚡ No configuration needed
- 📦 Works universally
- 🎯 Full context isolation
- ⚪ Generic terminal output

### Custom Agent (Optional - Power Users)

Enhanced UX with colored output:

```bash
# One-time setup
/agents create
  Name: graphite-ops
  Color: cyan
  Template: ./agents/graphite-ops-template.md

# Use with color
You: "graphite-ops check my stack"
graphite-ops [cyan]: ✓ feature/auth | 3 PRs | Review #456
```

**Characteristics:**
- 🎨 Colored terminal output
- 👤 Consistent persona
- 📁 Git-tracked definition
- 🎯 Same context isolation

See [Custom Agents Guide](docs/CUSTOM-AGENTS.md) for setup instructions.

## 🔧 How It Works

### SessionStart Hook

The plugin uses a SessionStart hook to inject context-optimization patterns into Claude's context window automatically:

```
1. Session starts → Hook fires
2. Hook detects: git repo, Graphite CLI, custom agent
3. Hook injects: ~800 tokens of patterns into context
4. Claude knows: Use Task delegation for verbose operations
5. User benefits: Automatic context efficiency, zero friction
```

### Automatic Delegation

When you request git/Graphite operations, Claude automatically:

1. Recognizes the operation will return verbose output
2. Delegates to Task subagent with explicit instructions
3. Subagent executes with `--json` and `2>/dev/null`
4. Subagent parses and returns summary <50 tokens
5. You receive concise, actionable summary

**No manual invocation needed - it just works!**

## 📊 Efficiency Metrics

| Metric | Before (Raw CLI) | After (Plugin) | Improvement |
|--------|------------------|----------------|-------------|
| Tokens consumed | 4,108 | 18 | **225x** |
| Context pollution | High | Minimal | **99.6% reduction** |
| Response quality | Degraded | Optimal | **Focused reasoning** |
| User effort | Manual patterns | Zero | **Automatic** |

## 🎯 Use Cases

### For Solo Developers

```bash
# Just use Claude naturally
"Check my stack"
"Show PRs needing review"
"Submit for review"

# Plugin handles context efficiency automatically
```

### For Teams

```bash
# One-time setup
git clone <your-repo>
./install.sh --project
git add .claude/
git commit -m "Add Graphite context-optimization"

# Team members pull and get:
# ✓ Automatic context optimization
# ✓ Consistent behavior
# ✓ Zero per-developer setup
```

### Supported Operations

**Graphite CLI:**
- `gt stack` - Stack status with delegation
- `gt pr list` - PR listing with filtering
- `gt pr info` - Detailed PR data with parsing
- `gt submit` - Submission with confirmation
- All other verbose gt commands

**Git:**
- `git log --graph` - Commit history with summarization
- `git diff` - Changes with statistics
- `git status` - Status with file grouping
- All other verbose git commands

## 🛠️ Configuration

### Default Configuration

The plugin works out-of-box with sensible defaults. No configuration required.

### Custom Configuration

Adjust behavior by editing `.claude/plugins/carbon/config.json`:

```json
{
  "contextTokens": 800,
  "delegationThreshold": 100,
  "autoDetectGraphite": true,
  "autoDetectCustomAgent": true,
  "enableTaskDelegation": true,
  "enableCustomAgent": true
}
```

See [Configuration Guide](docs/CONFIGURATION.md) for details.
