Claude Handoff

Goal-focused context transfer for Claude Code - transform /compact into system instructions that preserves the current task post-compact

What It Does

Claude-Handoff extends /compact with optional goal-focused handoff. When you run /compact handoff:<your goal> the plugin:

1. Captures your goal and current session state before compaction
2. Analyzes the previous thread to extract an immediate handoff instructions
3. Injects the handoff as a system message in the new, compacted session
4. Automatically starts the new session ready to execute your goal

Simply prompt the agent to 'proceed' and you're away.

How It Works

1. PreCompact Hook: Activates only when you use /compact handoff:... format

   • Extracts your goal from the handoff: prefix
   • Uses claude --resume <session> --fork-session --model haiku --print <prompt> to generate handoff immediately
   • Saves pre-generated handoff content and goal to .git/handoff-pending/handoff-context.json temporarily

2. Compact: Proceeds normally

3. SessionStart Hook: Runs in the continued session

   • Reads pre-generated handoff content from saved state
   • Injects handoff as system message
   • Cleans up state file

4. Result: Session continues with focused context injected, ready to execute your goal, just prompt it to go

Why?

Traditional compaction is lossy and unfocused - each summary degrades context quality. Goal-focused handoffs produce sharper results and get you back where you left off.

Trade-offs

Inspired by AmpCode's handoff model, and my own observations, this plugin auto-injects generated context without human review. Claude Code hooks can't pause for user editing.

PreCompact prompting for handoff adds some execution time to /compact, approximately ~20s.

Installation

# From your project directory
claude plugin marketplace add kylesnowschwartz/claude-handoff
claude plugin install claude-handoff

Usage

Trigger goal-focused handoff:

/compact handoff:now implement this for teams as well, not just individual users
/compact handoff:execute phase one of the created plan
/compact handoff:find other places in the codebase that need this same fix

Regular compact (no handoff):

/compact
/compact keep the context tight

Configuration

Enable debug logging: Edit handoff-plugin/hooks/lib/logging.sh and set LOGGING_ENABLED=true
