# latio-secure-supply-chain-skills

This plugin checks a repository for supply chain risks across dependencies, containers, and GitHub Actions, then fixes critical issues. Use it to audit and harden a project.

## What it does

The plugin reads project files to decide which checks apply. A `package.json` triggers package checks, while a `Dockerfile` brings container checks into scope. It also examines GitHub Actions, Terraform, AI models, IDE extensions, and credentials. Critical findings are changed in the repository, followed by a report of fixes and remaining work.

Commands that modify the project are separate from interactive walkthroughs for settings outside the codebase. Actions include pinning versions and SHAs, adjusting permissions, and disabling install scripts. Walkthroughs cover topics such as OIDC and image signing.

You need a working Claude Code installation and SSH access to GitHub, since the installer clones over SSH. Action commands make changes by default, so review those changes before running them on an important branch.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install latio-secure-supply-chain-skills@claude-community
```

## When to use it
- find floating dependency versions and risky install scripts
- pin GitHub Actions to SHAs and restrict workflow permissions
- lock container base images to digests
- locate hardcoded secrets and long-lived tokens
- follow setup steps for OIDC or image signing

## Example prompts
- Audit this repository's supply chain and fix critical findings.
- Pin the GitHub Actions to SHAs and check workflow permissions.
- Find long-lived tokens and secrets hardcoded in this repository.

# Supply Chain Security Plugin for Claude Code

Protect your projects from supply chain attacks with Claude.

## What Is This?

When you build software, you rely on hundreds of third-party packages, container images, GitHub Actions, and more. Attackers increasingly target these dependencies to sneak malicious code into otherwise trustworthy projects. This is called a **supply chain attack**.

This plugin gives Claude Code the ability to **audit your project** for supply chain risks and **fix them for you**, covering seven areas:

| Area | Examples of What Could Go Wrong |
|------|-------------------------------|
| **Packages** (npm, pip, etc.) | A dependency gets hijacked and runs a malicious install script |
| **Containers** (Docker) | Your base image silently changes to include a backdoor |
| **GitHub Actions** | A third-party Action gets compromised and steals your secrets |
| **Infrastructure as Code** (Terraform) | An unverified module provisions resources you didn't ask for |
| **AI/ML Models** | A pickle file executes arbitrary code when loaded |
| **IDE Extensions** | A VS Code extension exfiltrates code from your workspace |
| **Credentials** | A leaked API key or long-lived token enables lateral movement across services |

Based on the [Latio](https://latio.com) Supply Chain Security Checklist

## Getting Started

### Prerequisites

- [Claude Code](https://docs.anthropic.com/en/docs/claude-code) installed and working
- [SSH access to GitHub](https://docs.github.com/en/authentication/connecting-to-github-with-ssh) configured (the plugin installer clones via SSH)

### Installation

> **Note:** This plugin is pending addition to the official Claude Code marketplace. In the meantime, you can install it directly using the self-hosted marketplace below. Once it's in the official marketplace, you'll be able to install it with just `/plugin install supply-chain-security`.

Add the marketplace and install the plugin from within Claude Code:

```
/plugin marketplace add latiotech/secure-supply-chain-skills
/plugin install supply-chain-security@secure-supply-chain
```

After installing, run `/reload-plugins` to activate the plugin.

### Your First Audit

Once installed, open Claude Code in any project and run:

```
/audit-supply-chain
```

This scans your repo, figures out which areas apply to you, **auto-fixes critical items** (pinning versions, resolving SHAs, disabling install scripts), and gives you a report showing what was fixed and what still needs attention.

## Two Types of Commands

### Action Commands - Fix Issues Directly

These commands **take action by default**. They scan your repo, make changes (pin versions to exact hashes, resolve commit SHAs, fix configs), and explain each change as it's made. Run these first.

| Command | What It Does |
|---------|-------------|
| `/audit-supply-chain` | Full audit - detects what's in your repo, checks everything, auto-fixes critical items |
| `/harden-packages` | Pin dependency versions, disable install scripts, secure registry configs |
| `/harden-containers` | Pin base images by digest, enforce non-root, create .dockerignore |
| `/harden-actions` | Pin Actions to SHAs, set permissions, fix script injection, add Dependabot |
| `/harden-iac` | Pin Terraform modules/providers, generate lockfiles, flag provisioners |
| `/harden-ai-ml` | Fix unsafe torch.load/pickle.load, pin model sources, add hash verification |
| `/harden-ide-extensions` | Audit extensions, remove secrets from settings, add devcontainer config |
| `/harden-credentials` | Scan for leaked secrets, set up pre-commit hooks, harden .gitignore, fix credential anti-patterns |
| `/audit-credentials` | Find long-lived tokens, hardcoded secrets, credentials that should be rotated or replaced with OIDC |
| `/update-pins` | Check pinned deps, Actions, images, and modules for newer versions — auto-updates patch/minor, flags majors with changelogs |
| `/minimize` | Remove unused dependencies and convert Dockerfiles to multi-stage builds to reduce attack surface |
