Graphite Skill - Context-Efficient Git/Graphite Workflows

Stop drowning in verbose git/Graphite output. This skill automatically enables context-efficient workflows for all git and Graphite CLI operations in Claude Code through automatic delegation patterns.

Core Principles

1. Automatic Delegation: Verbose git/Graphite operations are automatically delegated to Task subagents
2. Context Isolation: Raw CLI output (15KB+) is processed in isolated context, summaries (<50 tokens) returned
3. Zero Friction: SessionStart hooks inject patterns automatically - no manual invocation needed
4. Team-Ready: Git-trackable configuration for team-wide distribution
5. 225x Efficiency: Dramatic context window improvements (4,108 tokens → 18 tokens)

Problem Statement

Before Graphite Skill (Context Pollution)

You: "Check my Graphite stack"
Claude: [Returns 15KB of JSON → 4,000+ tokens consumed]
Result: Context polluted, reasoning degraded, 2-3 operations max

Traditional git/Graphite operations flood context:

• gt stack → 15KB JSON (4,108 tokens)
• git log --graph → 50KB output (12,000+ tokens)
• gt pr info → 20KB JSON (5,000+ tokens)
• Multiple queries → Context window exhaustion

After Graphite Skill (Context Efficiency)

You: "Check my Graphite stack"
Claude: [Automatically delegates to Task subagent]
Subagent: [Processes 15KB in isolated context]
Claude: "✓ feature/auth | 3 PRs | Review #456"
Result: Clean context, 18 tokens used, 100+ operations possible

Installation

Auto-Detection (Recommended)

The skill automatically detects if setup is needed!

When you have the carbon-flow plugin installed globally but haven't set up Graphite Skill in your project, the SessionStart hook will automatically prompt you with:

⚠️ Graphite Skill Setup Required

Would you like to set up Graphite Skill in this project now?

If yes, run: bash ~/.claude/plugins/mad-skills/graphite-skill/install.sh --project

Simply run the provided command and the skill activates immediately. No need to remember or look up installation steps.

Prerequisites

• Git repository
• Claude Code 2.0+
• (Optional) Graphite CLI for Graphite-specific workflows
• (Optional) jq for JSON processing in hooks

Manual Installation

# Navigate to your project
cd /path/to/your/project

# Run the installer
bash ~/.claude/plugins/mad-skills/graphite-skill/install.sh --project

# The installer will:
# - Copy hooks to .claude/plugins/graphite-skill/
# - Configure SessionStart hook
# - Set up agent templates
# - Make scripts executable

Manual Installation

# In your project
mkdir -p .claude/plugins/graphite-skill/hooks

# Copy files from the carbon skill directory
cp ~/.claude/plugins/mad-skills/graphite-skill/hooks/session-start.sh .claude/plugins/graphite-skill/hooks/
cp ~/.claude/plugins/mad-skills/graphite-skill/settings.json .claude/plugins/graphite-skill/

# Make hook executable
chmod +x .claude/plugins/graphite-skill/hooks/session-start.sh

# Optional: Copy agent template
mkdir -p .claude/agents
cp ~/.claude/plugins/mad-skills/graphite-skill/agents/graphite-ops-template.md .claude/agents/

Verification

# Test hook execution
bash .claude/plugins/graphite-skill/hooks/session-start.sh

# Should output JSON with hookSpecificOutput

# Test in Claude Code
claude --debug hooks

# Look for:
# [SessionStart] Executing hook: session-start.sh
# [SessionStart] Hook completed successfully

How It Works

SessionStart Hook Mechanism

The skill uses a SessionStart hook to inject context-optimization patterns automatically:

1. Session starts → SessionStart hook fires
2. Hook detects: git repo, project setup status, Graphite CLI, custom agent
3a. If not set up → Prompts user to run install.sh (auto-detection)
3b. If set up → Hook injects ~800 tokens of delegation patterns into context
4. Claude knows: Use Task delegation for verbose operations automatically
5. User benefits: Automatic context efficiency, zero manual effort

Auto-Detection Logic:

The hook intelligently detects whether per-project setup has been completed by checking for the existence of .claude/plugins/graphite-skill/hooks/session-start.sh in your project directory.

• Not set up: Hook displays setup prompt with installation instructions
• Set up: Hook injects delegation patterns and activates context optimization

This means you never have to remember installation steps - the skill tells you exactly what to do.

Automatic Delegation Pattern

When you request git/Graphite operations, Claude automatically:

1. Recognizes the operation will return verbose output
2. Delegates to Task subagent with explicit instructions:
   • Use --json flags for structured output
   • Redirect errors with 2>/dev/null
   • Parse and summarize results
3. Subagent executes in isolated context (absorbs verbose output)
4. Subagent returns concise summary (<50 tokens)
5. You receive actionable summary without context pollution

No manual invocation needed - patterns apply automatically!

Workflows

Basic Git Operations

Checking status:

You: "Check git status"
Claude: [Delegates automatically]
→ "3 modified, 2 staged, 1 untracked | Ready to commit"

Viewing commit history:

You: "Show me recent commits"
Claude: [Delegates automatically]
→ "Last 10: abc123 Feature, def456 Fix, ... | 3 authors, 2 days"

Reviewing changes:

You: "Show git diff"
Claude: [Delegates automatically]
→ "+47/-12 across 3 files | auth.ts, api.ts, tests/ | No conflicts"

Graphite Workflows

Stack status:

You: "Check my Graphite stack"
Claude: [Delegates automatically]
→ "✓ feature/auth | 3 PRs | #456 (needs review), #457 (approved), #458 (draft)"

PR management:

You: "Show PRs needing review"
Claude: [Delegates automatically]
→ "📋 2 PRs: #456 (Auth - awaiting review), #459 (Docs - changes requested)"

Submitting stack:

You: "Submit my stack for review"
Claude: [Delegates automatically]
→ "✓ 3 PRs created | CI running on all | Ready for review"

Stack navigation:

You: "Navigate to next branch in stack"
Claude: [Delegates automatically]
→ "Switched to feature/auth-ui (3/5 in stack)"

Supported Operations

Git Commands (auto-delegated):

• git log --graph - Commit history with summarization
• git diff - Changes with statistics
• git status - Status with file grouping
• git branch - Branch listing with current indicator
• All other verbose git commands

Graphite CLI Commands (auto-delegated):

• gt stack - Stack status with PR summaries
• gt pr list - PR listing with filtering
• gt pr info - Detailed PR data with parsing
• gt submit - Submission with confirmation
• gt log - Stack history with formatting
• All other verbose gt commands

Two Approaches: Task Tool vs Custom Agent

Task Tool (Default - Recommended)

Zero setup, works immediately with automatic delegation:

You: "Check my stack"
Claude: [Uses Task delegation automatically]
→ Concise summary

Characteristics:

• ⚡ No configuration needed
• 📦 Works universally
• 🎯 Full context isolation
• ⚪ Standard terminal output
• ✅ Recommended for most users

Custom Agent (Optional - Power Users)

Enhanced UX with colored terminal output:

# One-time setup in Claude Code
/agents create
  Name: graphite-ops
  Color: cyan
  Scope: project
  Prompt: Load from .claude/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 (cyan)
• 👤 Consistent persona
• 📁 Git-tracked definition
• 🎯 Same context isolation
• 🔧 Requires one-time agent creation

Agent Template Location: graphite-skill/agents/graphite-ops-template.md

Team Distribution

Graphite Skill is designed for team-wide adoption:

# One team member sets up
./install.sh --project
git add .claude/
git commit -m "Add Graphite Skill context-optimization for git/Graphite"
git push

# Other team members pull and get:
# ✓ Automatic context optimization
# ✓ Consistent behavior across team
# ✓ Zero per-developer setup

Team benefits:

• Consistent git/Graphite workflows
• Automatic efficiency for all developers
• Git-tracked configuration (no separate distribution)
• SessionStart hook activates automatically

Configuration

Default Configuration

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

Custom Configuration

Adjust behavior by editing .claude/plugins/graphite-skill/settings.json:

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

Settings explanation:

• contextTokens: Amount of pattern context injected (default: 800)
• delegationThreshold: Token size to trigger delegation (default: 100)
• autoDetectGraphite: Automatically detect Graphite CLI presence (default: true)
• autoDetectCustomAgent: Detect and suggest custom agent if available (default: true)
• enableTaskDelegation: Enable automatic Task delegation (default: true)
• enableCustomAgent: Enable custom agent support (default: true)

Efficiency Metrics

Troubleshooting

Hook not firing

# Check permissions
chmod +x .claude/plugins/graphite-skill/hooks/session-start.sh

# Check settings.json exists
ls -la .claude/settings.json

# Test manually
bash .claude/plugins/graphite-skill/hooks/session-start.sh | jq .

Context not appearing

# Verify hook returns correct JSON
bash .claude/plugins/graphite-skill/hooks/session-start.sh | \
  jq '.hookSpecificOutput.hookEventName'

# Should output: "SessionStart"

Patterns not applied

Start Claude with debug mode:

claude --debug hooks

# Check for:
# - Hook execution confirmation
# - Context injection success
# - Any error messages

Delegation not automatic

If Claude doesn't delegate automatically:

1. Verify SessionStart hook is active: claude --debug hooks
2. Check hook output contains delegation patterns
3. Manually request delegation: "Use Task delegation for this"
4. Review hook configuration in settings.json
