Claude Code Plugins Marketplace
A Claude Code plugin marketplace. Plugins cover the full development lifecycle: release automation, design review, infrastructure verification, Home Assistant integration dev, Linux system administration, GitHub repo health, and plugin testing.
Installation
Add this marketplace to your Claude Code installation:
/plugin marketplace add L3DigitalNet/Claude-Code-Plugins
Or using the full URL:
/plugin marketplace add https://github.com/L3DigitalNet/Claude-Code-Plugins.git
Then install individual plugins:
/plugin install design-assistant@l3digitalnet-plugins
Staying Up to Date
Auto-update keeps plugins current automatically. To verify it's enabled:
- Run
/plugin in Claude Code
- Go to the Marketplaces tab
- Select l3digitalnet-plugins
- Look for Disable auto-update (meaning it's already on)
When auto-update is enabled, Claude Code refreshes the marketplace catalog and updates
installed plugins at the start of each session.
Manual update if you prefer to control when updates happen:
# Refresh the marketplace catalog
/plugin marketplace update l3digitalnet-plugins
# Then update individual plugins via /plugin → Installed tab → Update now

Principles
These principles apply across all plugins in this collection. Individual plugins may define additional principles scoped to their domain.
[P1] Act on Intent: Invoking a command is consent to its implied scope. When intent is ambiguous, clarify scope before executing, not after. When intent is clear, execute without narration or confirmation of the obvious. A confirmation gate is warranted only when an operation is both truly irreversible and its scope materially exceeds what the invocation implies, not for operations that are merely large or look dangerous. If scope materially changes mid-execution, stop and re-confirm. Routine friction is a tax, not a safeguard.
