Installation Guide — GRC Skills for Claude Code

This guide covers how to install the GRC Skills marketplace in Claude Code, the AI-powered CLI for developers. The marketplace provides five compliance skills as Claude Code plugins — each one extends Claude Code with deep, framework-specific expertise for ISO 27001, SOC 2, FedRAMP, GDPR, and HIPAA.

What Are Claude Code Plugins?

Plugins let you extend Claude Code with custom functionality that can be shared across projects and teams. A plugin can contain skills (instructions Claude follows automatically), commands (slash commands you invoke), agents, hooks, and MCP servers. Once installed, a plugin is available in every Claude Code session on that machine.

A marketplace is a catalog of plugins hosted in a Git repository. You add a marketplace once, then install any plugin it lists by name.

Prerequisites

1. Add the Marketplace

Register the GRC Skills marketplace with a single command. You only need to do this once per machine.

/plugin marketplace add Sushegaad/Claude-Skills-Governance-Risk-and-Compliance

Claude Code will clone the repository, read the .claude-plugin/marketplace.json catalog, and register it locally as grc-skills. You can confirm it was added with:

/plugin marketplace list

2. Install Individual Skills

Once the marketplace is registered, install only the frameworks you need.

/plugin install iso27001@grc-skills

/plugin install soc2@grc-skills

/plugin install fedramp@grc-skills

/plugin install gdpr-compliance@grc-skills

/plugin install hipaa-compliance@grc-skills

Each plugin is installed to a local cache (~/.claude/plugins/cache) and activates immediately in new Claude Code sessions.

3. Install All Five at Once

To install the full GRC suite in a single command:

/plugin install iso27001@grc-skills soc2@grc-skills fedramp@grc-skills gdpr-compliance@grc-skills hipaa-compliance@grc-skills

4. Team Setup — Auto-Install via Project Settings

For teams, you can pre-wire the marketplace into your project so every developer gets the skills automatically when they open the project in Claude Code — no manual install step required.

Add the following to your project’s .claude/settings.json:

{
  "extraKnownMarketplaces": {
    "grc-skills": {
      "source": {
        "source": "github",
        "repo": "Sushegaad/Claude-Skills-Governance-Risk-and-Compliance"
      }
    }
  },
  "enabledPlugins": {
    "iso27001@grc-skills": true,
    "soc2@grc-skills": true,
    "fedramp@grc-skills": true,
    "gdpr-compliance@grc-skills": true,
    "hipaa-compliance@grc-skills": true
  }
}

Commit this file to your repository. The next time a team member trusts the project folder in Claude Code, the marketplace and plugins will be registered automatically. Only enable the skills your team actually needs — you don’t have to include all five.

Keeping Skills Up to Date

When this repository is updated with new skill content or bug fixes, refresh your local copy with:

/plugin marketplace update grc-skills

To update a specific installed plugin:

/plugin update iso27001@grc-skills

Uninstalling

To remove a plugin:

/plugin uninstall iso27001@grc-skills

To remove the marketplace entirely:

/plugin marketplace remove grc-skills

Available Skills

Plugin name Framework What it does
iso27001 ISO 27001:2022 Gap analysis, policy writing, Annex A control guidance, SoA generation, risk registers
soc2 SOC 2 TSC gap analysis, policy drafting, control documentation, audit evidence, vendor risk
fedramp FedRAMP Moderate/High Readiness assessments, SSP narratives, POA&M, NIST 800-53 control mapping, ConMon
gdpr-compliance GDPR / UK GDPR Code audits, privacy notices, DPAs, DPIAs, data flow reviews, article-cited Q&A
hipaa-compliance HIPAA Document generation, technical safeguards for cloud, breach response guidance

Troubleshooting

Marketplace not found after adding Run /plugin marketplace list to confirm it was registered. If it’s missing, check that your Git credentials allow access and retry.

Plugin installation fails Verify you have network access to GitHub and that your Git version is current. You can also clone the repo manually to test: git clone https://github.com/Sushegaad/Claude-Skills-Governance-Risk-and-Compliance.git

Skills not activating in sessions Restart Claude Code after installing plugins. Skills activate in new sessions, not mid-session.

Git timeout on slow connections Increase the timeout via environment variable before running Claude Code:

export CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS=300000
