Essential Plugins for Claude Code CLI

**For a fresh Claude Code CLI setup, here's a targeted "gear up" plan based on official Anthropic docs and reliable 2026 sources (Claude Code plugin docs, official marketplace, and top community-curated lists).** Claude Code plugins bundle **skills** (extra instructions/commands), **sub-agents**, **hooks** (automation triggers), **MCP servers** (Model Context Protocol for safe external tool/API connections), and LSPs (code intelligence). They turn the CLI into a powerful agentic dev/automation environment without custom scripting. ### Step 0: Quick Official Check (Do This First) Launch Claude Code (`claude`) in your terminal. Run these inside the session: - `/plugin marketplace list` → confirm `claude-plugins-official` is there (it's auto-loaded on fresh installs). - `/plugin list` → see what's already installed. **For any official Claude plugins from `claude-plugins-official` (the Anthropic-managed marketplace):** just check if you already have them. If missing, install with `/plugin install @claude-plugins-official` (user scope is default and fine for a personal VPS). Then run `/reload-plugins`. ### Primary Plugins to Install / Verify (Dev + Automation Foundation) These are the most-cited high-impact ones across official docs and 2026 guides for a clean dev setup. Focus on these first—they cover code intelligence, security, git, browser automation, and context. - **context7** (MCP): Real-time library/framework docs injected into context → cuts hallucinations on versions/APIs. Essential for any dev work. `/plugin install context7@claude-plugins-official` - **playwright** (MCP + skills): Natural-language browser automation/testing. Claude can open/control real browsers for UI flows, E2E tests, scraping. Great on VPS (headless-friendly). `/plugin install playwright@claude-plugins-official` - **security-guidance** (hooks): Auto-scans edits for vulns (XSS, injections, etc.) and blocks risky changes pre-commit. `/plugin install security-guidance@claude-plugins-official` - **github** (MCP): Full GitHub integration (repos, PRs, issues, commits). `/plugin install github@claude-plugins-official` These give you immediate wins on a fresh VPS: safer code, better context, browser automation, and git workflows. **After installing any:** `/reload-plugins` (or restart the `claude` session). ### Trending Plugins for Development, Automation, and Agentic Workflows (2026) These are the hottest right now for **agentic** (autonomous/self-improving) behavior, MCP connections, and heavy automation. Install the ones matching your workflow. Sources: top-10 roundups, Reddit/Dev.to discussions, and marketplace data. **Agentic Power-Ups (make Claude think/act more autonomously):** - **superpowers** (@claude-plugins-official): The #1 trending agentic framework. Adds structured workflows, smarter planning/questions, sub-agents, testing hooks, and context gathering. Transforms Claude into a more methodical dev partner. `/plugin install superpowers@claude-plugins-official` (Now officially available—no extra marketplace needed.) - **ralph-loop** (or ralph-wiggum variant, official/community): Autonomous looping agent. Give it a task + completion criteria → Claude iterates on its own (hours-long sessions, git as memory) until done. Perfect for migrations, big refactors, or "set it and walk away." `/plugin install ralph-loop@claude-plugins-official` (or ralph-wiggum@claude-plugins-official if that's the exact name shown in /plugin discover). **MCP & Automation Standouts:** - **firecrawl** (MCP server + skills): Best-in-class web scraping/crawling/search with JS rendering and clean markdown/JSON output. Turns Claude into a real-time research/automation agent. (You'll need a Firecrawl API key in settings.) `/plugin install firecrawl@claude-plugins-official` - **linear** (MCP, if you use Linear): Create/update tickets directly from Claude. Closes the loop between code and task tracking. `/plugin install linear@claude-plugins-official` **Dev-Specific Nice-to-Haves (if relevant):** - **frontend-design** (skill): Professional UI/UX principles baked in (typography, layouts, etc.). `/plugin install frontend-design@claude-plugins-official` - **code-review** (sub-agents): Multi-agent PR/code review with confidence scores. `/plugin install code-review@claude-plugins-official` **Language-Specific LSPs** (for code intelligence like autocomplete/diagnostics): Check official list with `/plugin discover` and install the one for your stack (e.g., `pyright-lsp`, `typescript-lsp`, `rust-analyzer-lsp`). You'll also need the underlying language server binary installed via apt/pip/etc. on Ubuntu. ### Quick Gear-Up Commands (Copy-Paste in a Claude Session) ```bash # 1. Check what's there /plugin list # 2. Core primary stack (official) /plugin install context7@claude-plugins-official /plugin install playwright@claude-plugins-official /plugin install security-guidance@claude-plugins-official /plugin install github@claude-plugins-official # 3. Trending agentic + MCP /plugin install superpowers@claude-plugins-official /plugin install ralph-loop@claude-plugins-official /plugin install firecrawl@claude-plugins-official /reload-plugins ``` ### Pro Tips for Ubuntu VPS - Run everything inside `claude` sessions (or script with non-interactive flags like `-p` for pipelines). - For MCP tools (firecrawl, linear, etc.), add API keys via `~/.claude/settings.json` or the plugin prompts. - Playwright may need system deps on Ubuntu: `sudo apt update && sudo apt install -y chromium-browser` (or let the plugin guide you). - Use hooks in plugins for auto-linting/testing after edits. - Explore more via `/plugin` (Discover tab) or add community marketplaces only if needed (e.g., for niche ones). This starter set will make your fresh VPS Claude Code feel like a full agentic dev platform—context-aware, secure, automated, and capable of long-running autonomous tasks. Start with the primary/official checks, add the trending agentic/MCP ones, and you'll be geared up fast.
