Handoffkit

HandoffKit Plugin for Claude Code

Push AI session handoffs directly to HandoffKit from Claude Code. No more copy-pasting between your terminal and the browser.

What it does

This plugin provides a one-command setup (/handoffkit:setup) that connects your Claude Code project to HandoffKit via MCP. Once connected, you gain a push-handoff tool that sends session handoff messages to HandoffKit as new cells.

• One-time setup per project — run /handoffkit:setup, paste a token, done
• Per-project scoping — each project directory links to its own HandoffKit project
• Secure — API keys stored by Claude Code, not in project files
• Non-blocking — if the push fails, your handoff is still complete locally

Setup

In Claude Code, add the marketplace and install the plugin:

/plugin marketplace add Norsninja/handoffkit-plugin
/plugin install handoffkit@norsninja

Then link a project:

1. Go to handoffkit.com/settings → Plugin Integration → Generate Token
2. Select the project you want to link
3. Copy the token (starts with hk_setup_, expires in 10 minutes)
4. In Claude Code, in your project directory, run /handoffkit:setup
5. Paste the token when prompted

That's it. Restart Claude Code and the push-handoff MCP tool is available.

If your project has a legacy .handoffkit.json (with an api_key field) from an earlier prototype, /handoffkit:setup detects it automatically, migrates the file to a credential-free marker, updates your /handoff command, and revokes the old key on the server.

How it works

The setup skill exchanges your one-time token for a project-scoped API key, then runs claude mcp add --scope local to create a per-project MCP connection to HandoffKit's remote server at handoffkit.com/api/mcp. After setup, the plugin itself is optional — the MCP connection persists independently.

Usage

After setup, you can:

• Add a push step to your /handoff command to auto-sync chat messages
• Ask Claude to "push this to HandoffKit" anytime
• The push-handoff tool sends only the concise chat message, never full handoff files

Multiple projects

Run /handoffkit:setup in each project directory with a token generated for that HandoffKit project. Each directory gets its own isolated connection.

Security

• Setup tokens expire in 10 minutes and are single-use
• API keys are project-scoped — can't access other projects
• Keys are stored by Claude Code in ~/.claude.json, not in project files
• Revoke keys anytime at handoffkit.com/settings
• All communication is HTTPS

Requirements

• A HandoffKit account (free tier works)
• Claude Code with MCP support
• curl available in your shell
