Company Tools — Claude Code Plugin Marketplace

Internal Claude Code plugin marketplace for HD Ecom engineering teams. Provides shared skills and enforces consistent AI-assisted development practices org-wide.

Jira: BAU-9383 · BAU-9146

---

Available Plugins

Plugin	Description
coding-standards	Enforces .NET/C# naming, file structure, and error handling conventions
pr-review	Structured PR reviews: security, performance, readability, test coverage

---

Installing the Marketplace

Run once per machine (or per Claude Code profile):

/plugin marketplace add company-tools

When prompted, confirm the source: github:OWNER/claude-plugins-marketplace

Auto-install: If this repo is listed in a project's .claude/settings.json under extraKnownMarketplaces, Claude Code will prompt you to add it automatically the first time you trust the folder.

---

Installing Plugins

After adding the marketplace:

/plugin install coding-standards@company-tools
/plugin install pr-review@company-tools

Or install both at once from the marketplace browser (/plugin marketplace browse company-tools).

---

Updating Plugins

When changes are pushed to this repo, update your local copies:

/plugin marketplace update company-tools

Auto-updates: Claude Code checks for marketplace updates at startup. You may be prompted to update automatically.

---

Using Skills

Once installed, invoke skills via slash commands in Claude Code:

/coding-standards
/pr-review

Or trigger them by describing what you want — Claude will match the relevant skill from context.

---

Enterprise Deployment

To enforce this marketplace org-wide and restrict users to approved sources, deploy the managed-settings.json snippet at the root of this repo via your enterprise Claude Code configuration.

Replace OWNER with your GitHub org name before deploying. The strictKnownMarketplaces setting prevents users from adding unapproved plugin sources.

Rules

• Plugin names must be kebab-case (e.g. api-testing, not apiTesting or api_testing)
• Plugins cannot reference files outside their own directory — they are copied to a local cache on install
• Use ${CLAUDE_PLUGIN_ROOT} in hooks or MCP configs if you need to reference plugin-relative paths
• Skills should be self-contained: don't assume other plugins are installed

Adding to the marketplace

1. Create your plugin directory under plugins/
2. Add an entry to .claude-plugin/marketplace.json:

{
  "name": "your-plugin-name",
  "description": "One sentence description",
  "category": "development",
  "source": "./plugins/your-plugin-name"
}

3. Run ./validate-marketplace.sh to check everything is correct
4. Open a PR — tag a team member for review
