lenne.tech Claude Code Plugins

Claude Code Plugins by lenne.tech.

Installation

Via lenne.tech CLI (recommended)

# Install CLI if not already installed
npm i -g @lenne.tech/cli

# Install or update plugin and configure permissions
lt claude plugin

Manual Installation

# Add marketplace
/plugin marketplace add lenneTech/claude-code

# Install plugin
/plugin install lt@lenne-tech

Note: Manual installation requires you to configure permissions yourself. Copy the permission patterns from plugins/lt/permissions.json into ~/.claude/settings.json:

{
  "permissions": {
    "allow": [
      // Copy patterns from permissions.json
    ]
  }
}

If the file already exists, merge the allow entries with your existing permissions. See plugins/lt/permissions.json for the current list of required permissions.

3. lt CLI Detection - Detects installed lt CLI and suggests using-lt-cli skill for Git and Fullstack operations

MCP Servers (2)

The plugin includes pre-configured MCP (Model Context Protocol) servers that start automatically:

MCP Server	Description
chrome-devtools	Chrome DevTools integration for debugging web applications
linear	Linear integration for issue tracking and project management

Requirements

• Claude Code CLI
• Node.js >= 18
• lenne.tech CLI (npm i -g @lenne.tech/cli) - for automatic permission setup

Development

# Version bump (patch, minor, major) with change description
bun run version:patch "Fixed hook detection for monorepos"
bun run version:minor "Added new skill for API testing"
bun run version:major "Breaking changes in hook configuration"

The script updates plugin.json + package.json, creates commit, tag and pushes automatically.

Permissions Configuration

The file plugins/lt/permissions.json defines all Bash permissions required by the skills. The lenne.tech CLI reads this file during installation and automatically configures the permissions in ~/.claude/settings.json.

Important: When adding or modifying skills that use new CLI commands, update permissions.json accordingly:

{
  "permissions": [
    {
      "pattern": "Bash(your-command:*)",
      "description": "Description of what this permission allows",
      "usedBy": ["skill-name-that-uses-it"]
    }
  ]
}

Each permission entry contains:

• pattern: The permission pattern for Claude Code (e.g., Bash(npm test:*))
• description: Human-readable description of the permission
• usedBy: Array of skill names that require this permission
