PretInnov Plugins — Claude Code Plugin Marketplace

By Siddharth Gupta | PretInnov Technologies

Three production-grade plugins that make Claude Code smarter, safer, and capable of building its own extensions.

What's Inside?

Plugin	What It Does	One-Liner
Clamper	Verifies your code, maps your project DNA, and scaffolds full agent ecosystems	"Clip it, Clamp it."
Cortex	Remembers what worked and what failed across ALL your sessions, then uses that knowledge automatically	"Claude Code with a brain."
Forge	Creates entire plugins from a simple chat prompt — researches, asks questions, designs, and generates everything	"Build plugins by talking."

How to Install (Step by Step)

What You Need First

• Claude Code installed on your machine. If you don't have it yet, go to claude.ai/code and follow the install instructions.
• That's it. No other software needed.

Step 1: Add This Marketplace

This tells Claude Code "hey, there's a plugin store at this GitHub repo." You only do this once.

Option A — Using the Terminal (CLI):

Open your terminal and type:

claude plugin marketplace add github:PretInnov-Inc/forge-marketplace

Option B — Using the Desktop App:

1. Open Claude Code desktop app
2. Go to Settings (gear icon)
3. Click Plugins
4. Click Add Marketplace
5. Type in: PretInnov-Inc/forge-marketplace
6. Click Add

Option C — From inside a Claude Code chat session:

Just type this as a message:

/plugin marketplace add github:PretInnov-Inc/forge-marketplace

Step 2: Install the Plugins You Want

Now you can install any (or all) of the 3 plugins:

# Install all three:
claude plugin install clamper@pretinnov-plugins
claude plugin install cortex@pretinnov-plugins
claude plugin install forge@pretinnov-plugins

Or from inside a Claude Code session:

/plugin install clamper@pretinnov-plugins
/plugin install cortex@pretinnov-plugins
/plugin install forge@pretinnov-plugins

Step 3: Verify They're Installed

Type /help inside Claude Code — you should see the new commands listed under their plugin namespaces.
