Spawn a new Claude Code session in a project directory with context handoff. This skill should be used when discussion shifts to a different project/repo and the user wants to work on it in a dedicated session. Creates a handoff document with relevant context from the current conversation, then launches a new tmux session with Claude Code ready to continue.

Project Spawn

Overview

Transfer context from the current conversation to a new Claude Code session in a different project directory. This enables seamless context handoff when pivoting from a general session to focused project work.

Workflow

Step 1: Resolve Target Project

Determine the target project directory:

  1. If explicit path provided: Use directly (e.g., ~/repos/my-project)
  2. If relative path provided: Resolve from current working directory
  3. If no target specified: Ask the user which project they want to work on

Step 1b: Handle Non-Existent Directory

If target directory doesn't exist, ask user:

"Directory <path> doesn't exist. Want me to create it?"

  • Create folder only
  • Create folder + init git repo
  • Create folder + init git + create GitHub repo (public)
  • Create folder + init git + create GitHub repo (private)
  • Cancel

Create as requested before proceeding to Step 2.

Step 2: Extract Relevant Context

Analyze the last 5-10 messages for content relevant to the target project:

  • Tasks or work items discussed
  • Specific files, scripts, or features mentioned
  • Decisions made or questions raised
  • Any errors or issues identified
  • Uncommitted changes noted

Focus only on information relevant to the target project, not the entire conversation.

Step 3: Create Handoff Document

Write PROJECT_HANDOFF.md to the target project directory:

# Project Handoff - [DATE] [TIME]

## Context
[Why this handoff is happening - what triggered the pivot]

## Discussion Summary
[Relevant context extracted from conversation]

## Specific Tasks/Questions
- [Actionable items identified]

## Files/Areas Mentioned
- [Specific files or code areas referenced]

## Suggested Starting Point
[What to do first in this session]

Step 4: Launch Session

Execute the spawn script to create the new session:

~/.claude/skills/project-spawn/scripts/spawn_session.sh "<project-path>" "<session-name>"

The script will:

  1. Create a new tmux session named after the project
  2. Change to the project directory
  3. Start Claude Code with initial prompt to read the handoff

Step 5: Confirm to User

Report:

Spawned: <session-name>
Directory: <project-path>
Handoff: PROJECT_HANDOFF.md created

To attach: tmux attach -t <session-name>

Quick Reference

Invocation: /spawn <project-path> or mention wanting to work on a different project

Session naming: Uses repo folder name (e.g., my-project)

Handoff location: <project-dir>/PROJECT_HANDOFF.md
