+## Scripts
+
+The [`scripts/`](scripts/) directory contains utility shell scripts for maintaining your Claude Code setup.
+
+| Script | Description |
+|--------|-------------|
+| [`update-cc-plugins.sh`](scripts/update-cc-plugins.sh) | Update all installed Claude Code marketplaces and plugins/skills in one command |
+
+**Usage:**

 ## Limitations
 
 **WebSearch** tool in Claude Code is an [Anthropic specific tool,](https://docs.anthropic.com/en/docs/agents-and-tools/tool-use/web-search-tool) and it is not available when you’re not using the official Anthropic API. Hence, if you need web search, you'd need to connect Claude Code with external web search MCP servers, e.g. [Tavily MCP](https://docs.tavily.com/documentation/mcp), [Brave MCP](https://github.com/brave/brave-search-mcp-server), [Firecrawl MCP](https://docs.firecrawl.dev/mcp-server) or [DuckDuckGo Search MCP](https://github.com/nickclyde/duckduckgo-mcp-server).

+
+## update-cc-plugins.sh
+
+Bulk-updates all installed Claude Code marketplaces and plugins/skills in one shot.
+
+**Usage:**
+
+```sh
+bash ~/.claude/scripts/update-cc-plugins.sh
+```
+
+**What it does:**
+
+1. Runs `claude plugin marketplace update` to refresh all configured marketplaces.
+2. Reads `~/.claude/plugins/installed_plugins.json` and calls `claude plugin update <plugin>` for each entry.
+3. Prints a summary: how many plugins were updated, skipped (no longer in the marketplace), or failed.
