What is a Claude Code Plugin?
Claude Code plugins are extensions that add new capabilities to the Claude Code CLI. A plugin can provide:
- Skills - Slash commands (e.g.,
/ssw-plugin:ssw-download) that give Claude specialized knowledge and workflows
- Agents - Custom subagent definitions for specialized tasks
- Hooks - Event handlers that respond to Claude Code lifecycle events
- MCP Servers - External tool integrations via Model Context Protocol
- LSP Servers - Code intelligence via Language Server Protocol
Plugins are distributed through marketplaces - Git repositories that catalog one or more plugins. Users add a marketplace, then install individual plugins from it.
Installation
Step 1: Add Marketplace
Open Claude Code and register the ssw-plugin marketplace:
Option A: Inside Claude Code (interactive)
/plugin marketplace add https://github.com/tykimos/ssw-plugin.git
Option B: From terminal (CLI)
claude plugin marketplace add https://github.com/tykimos/ssw-plugin.git
This clones the repository to ~/.claude/plugins/marketplaces/ssw-plugin/ and registers it in ~/.claude/plugins/known_marketplaces.json.
Step 2: Install Plugin
Option A: Inside Claude Code (interactive)
/plugin install ssw-plugin@ssw-plugin
The format is <plugin-name>@<marketplace-name>.
Option B: From terminal (CLI)
claude plugin install ssw-plugin@ssw-plugin
Option C: Interactive plugin manager
/plugin
This opens the plugin manager UI. Navigate to the Discover tab to browse and install available plugins.
Installation Scopes
You can control where the plugin is available:
# Available in all your projects (default)
claude plugin install ssw-plugin@ssw-plugin --scope user
# Available only in current project, shared with team via git
claude plugin install ssw-plugin@ssw-plugin --scope project
# Available only in current project, not shared (gitignored)
claude plugin install ssw-plugin@ssw-plugin --scope local
| Scope | Settings File | Shared via Git | Use Case |
|---|
user | ~/.claude/settings.json | No | Personal use across all projects |
project | .claude/settings.json | Yes | Team-wide plugin for a project |
local | .claude/settings.local.json | No | Personal use for one project |
Step 3: Verify Installation
After installation, verify the plugin is active:
/plugin
You should see ssw-plugin listed as Enabled. The following slash commands should be available:
/ssw-plugin:ssw-download/ssw-plugin:ssw-prep/ssw-plugin:ssw-ml/ssw-plugin:ssw-viz
You can also test by typing /ssw- and checking autocomplete suggestions.
Step 4: Install Python Dependencies
The plugin skills require Python packages. Install them in your environment:
# Core: solar data download and preprocessing
pip install git+https://github.com/sswlab/ssw-tools
pip install sunpy matplotlib astropy aiapy
# Optional: for ML tasks (ssw-ml skill)
pip install torch torchvision scikit-image
# Optional: for logging in batch processing
pip install loguru
