Installation

Lineup is a Claude Code plugin. You need Claude Code installed and working before adding Lineup.

Prerequisites

• Claude Code installed and configured with a valid API key or valid subscription
• A terminal where you can run claude commands

Choose your install method

Method	Best for	Time
Marketplace	Most users -- quick, auto-updating	1 minute
Manual	Contributing to Lineup, inspecting source	2 minutes
Customized	Tweaking agent models, tools, or memory	3 minutes

Marketplace install

Register the izantech marketplace (one-time setup):

claude plugin marketplace add izantech/claude-plugins

Then install Lineup:

# From within Claude Code:
/plugin install lineup@izantech

# Or from terminal:
claude plugin install lineup@izantech

To update later:

claude plugin update lineup@izantech

That's it. You now have the lineup: namespace with all skills and agents available.

Manual install

Clone the repository and point Claude Code at it:

git clone https://github.com/izantech/lineup.git
claude --plugin-dir /path/to/lineup

This loads all agents and skills automatically. The lineup: namespace comes from the plugin name in plugin.json.

Use this method when you want to read or modify the source, or contribute changes back to the project.

Customized install

Note: You can use /lineup:configure with any installation method (marketplace, manual, or customized) to adjust agent settings interactively.

For deeper customization (modifying agent instructions, adding custom agents, or changing plugin behavior), clone the repository and point Claude Code at your local copy:

git clone https://github.com/izantech/lineup.git
claude --plugin-dir /path/to/lineup

Now you can:

• Edit files directly (agent definitions in agents/, skill logic in skills/)
• Use the configurator for model/tool/memory changes:

/lineup:configure

See the Customize Agents guide for details on what you can change with the configurator vs. manual file edits.

Verify installation

After installing, confirm everything is working:

/lineup:kick-off Hello, just checking the pipeline works!

You should see the orchestrator respond and begin the Clarify stage. You can cancel at any point -- the goal is just to confirm the skill loads.

Troubleshooting

Plugin not found

If /lineup:kick-off is not recognized:

• Marketplace install: Make sure the marketplace was added first with claude plugin marketplace add izantech/claude-plugins, then re-run /plugin install lineup@izantech.
• Manual install: Verify the --plugin-dir path points to the directory containing .claude-plugin/plugin.json. The path should be to the lineup root, not to a subdirectory.

Skills load but agents fail

If the skill starts but agent delegation fails:

• Check that all files in agents/ are present (researcher, architect, developer, reviewer, documenter, teacher).
• For customized installs, run /lineup:configure and choose Reset to restore default agent settings.

"No such agent" errors

Agent names are auto-namespaced by the plugin. You should see agents like lineup:researcher, lineup:architect, etc. If you see bare names without the lineup: prefix, the plugin manifest may not be loading correctly -- confirm .claude-plugin/plugin.json exists and has "name": "lineup".
