Discover, install, and manage plugins from your terminal. The CLI reads from this repo's published catalog—no manual cloning required.

```bash

pnpm add -g @intentsolutionsio/ccpi

```

Or with npm/yarn:

```bash

npm install -g @intentsolutionsio/ccpi

yarn global add @intentsolutionsio/ccpi

```

Usage

```bash

# Search plugins by keyword

ccpi search devops

# List all available plugins

ccpi list

# List installed plugins

ccpi list --installed

# Install a plugin

ccpi install ansible-playbook-creator

# Install multiple plugins at once

ccpi validate ./my-plugin

```

How It Works

• This repo is the source of truth — All plugins live in plugins/ and catalog in .claude-plugin/marketplace.extended.json
• Website publishes versioned catalog — On merge to main, the catalog JSON is deployed to claudecodeplugins.io
• CLI consumes catalog with caching — Fetches latest catalog on first use, caches locally for speed

Update Model

• Catalog updates: Happen automatically when PRs merge to main
• CLI releases: Only when CLI code changes (version bumps in packages/cli/)
• Plugin updates: Run ccpi update to pull latest versions
