Claude Spawner for VS Code

The missing link for Claude Code workflows: Spawn new Claude Code instances directly from within Claude Code!

Finally, you can programmatically create fresh Claude Code sessions with custom parameters - solving the context pollution problem and enabling true multi-task AI workflows.

Features

• 🔄 Claude-to-Claude Spawning: Use Claude slash commands or agents to spawn new Claude instances

Why Claude Spawner?

When working with Claude on complex projects, context pollution becomes a major issue. You start solving one problem, then need to document it, then need to solve a related issue - and suddenly your conversation is a tangled mess.

Claude Spawner solves this by letting you spawn fresh Claude instances on-demand:

• From Claude slash commands: Create a /spawn command that opens a new Claude with your problem statement
• From Claude agents: Let your agents spawn specialized Claude instances for subtasks
• With perfect context: Each session starts clean with only the context it needs

Requirements

• macOS only (Windows and Linux support coming soon)
• VS Code 1.74.0 or higher
• Claude CLI installed and authenticated

Installation

1. Install from the VS Code Marketplace (search for "Claude Spawner")
