Pick your environment, install in seconds
A Claude plugin is an installable bundle of skills. In Cowork you drag a file in; in Claude Code you add the marketplace once. Both install the same plugin.
Cowork and Claude Code, side by side
In the desktop app, dragging the file in is easiest. In the terminal, the marketplace gives you git-backed updates.
Cowork (desktop app)
In the Claude desktop app, the simplest way is to download the .plugin file and drag it into the Cowork sidebar — or open it from the chat. No commands needed.
- Download the plugin's .plugin file from its page.
- Drag the file into the Cowork sidebar, or open it from the chat.
- Confirm the installation when Claude asks.
Download the .plugin from any plugin page, then drag it in.
Claude Code (CLI)
In the terminal, add the marketplace once and install any plugin by name. Updates then flow through git.
Install all five from the marketplace
In Claude Code, add the marketplace once, then install any plugin by name.
Everything is plain Markdown
Skills are readable text. Open the source and read exactly what Claude will load.
No binaries, no obfuscation. Each plugin's repository holds its SKILL.md and reference files in the open, so you can review a skill before it ever runs in your session.
Common questions
How do I install a plugin in Cowork?
Download the plugin's .plugin file from its page on this site and drag it into the Cowork sidebar, or open it from the chat. Claude will ask you to confirm. No commands or marketplace setup are needed in the desktop app.
How do I install a plugin in Claude Code?
Add the marketplace once with “/plugin marketplace add joseconti/skills-joseconti-com”, then install any plugin by name with “/plugin install <name>@skills-joseconti-com”. Updates arrive through git when you re-run the marketplace add.
Do I need to add the marketplace to use a plugin?
No. Adding the marketplace is the Claude Code path. In Cowork you can install directly from the downloaded .plugin file without registering any marketplace.
Are the skills safe to read before installing?
Yes. Every skill is plain Markdown with no binaries or obfuscation. Each plugin's “View source” link opens its public repository so you can read exactly what Claude will load before it ever runs in your session.
