Claude Code plugins, explained — packs, boilerplates and factories

ShipClaude Guides · 5 min read

Claude Code's plugin system turns the editor-agent into a platform: a plugin ships slash-commands, specialist agents, and knowledge packs that load on demand. Install is two commands inside any session:

The three species of plugin

• Agent packs — shelves of specialists (a reviewer, an SEO writer, a DB expert…). Powerful if you already know what to build and in what order; overwhelming if you don't.
• Boilerplates — a pre-configured project template (auth, payments wired). They answer "how do I start fast", not "what should I build".
• Factory lines — sequenced pipelines with decision gates: research → validation → build → launch, with state that survives across sessions. Fewer commands, more outcome.

What to check before buying any of them

1. Does it bring data or just prompts? Prompts can be copied from GitHub; live data engines and real integrations can't.
2. Token economics: a plugin's always-on cost loads into every session. Under ~5k tokens is healthy; 50k of always-on agents is a tax.
3. Update path: store rules and APIs change monthly — a git-based plugin with lifetime updates ages well; a zip from a newsletter doesn't.
4. Independence disclosure: serious products state clearly they're not affiliated with Anthropic.
