Claude Code Plugins (2026): What Developers Install
The best Claude Code plugins, picked from the setups developers publish after pruning their own installs and from Hacker News threads where people say what they kept, not from install counts alone.
Superpowers
The one plugin nearly every published setup has in common. Its skills make Claude brainstorm a spec, write a plan and work test-first before it touches code, and staff engineer Riddam Jain says it replaced his habit of coding before deciding what to build. That slowness is the catch: Hacker News users report it spending far more tokens than plain Claude Code, and one saw a small change spawn four plans and four agents.

TypeScript LSP
Language server plugins are the quiet winners in three separate field logs. They hand Claude real diagnostics, go-to-definition and references, so it sees the type error it just wrote and fixes it in the same turn. Anthropic ships one per language, including pyright-lsp, gopls-lsp, rust-analyzer-lsp and swift-lsp. The plugin only does the wiring: you still install the language server binary yourself.

- What it adds
- A language server: diagnostics, go-to-definition, find references
Context7
Pulls current, version-specific library docs into the session so Claude stops writing APIs that were renamed two releases ago. Augusteo uses it constantly, and Luca Cavallin has a standing rule telling Claude to check it before answering from memory. It is an MCP server in plugin packaging, and Context7's free plan stops at 1,000 API calls a month. Riddam Jain admits his copy rarely fires.

- What it adds
- One MCP server for up-to-date library documentation
Plannotator
Opens Claude's plan in your browser, where you highlight, comment and send the notes back, and does the same for diffs. On Hacker News several people say it has replaced plan mode for them, and one prefers it to Superpowers because it does a single job. It is not in Anthropic's marketplace, so you add the maker's own first. One user's complaint: review comments are not kept alongside the commit.
- Install
- /plugin install plannotator@plannotator
- Marketplace
- /plugin marketplace add backnotprop/plannotator
- GitHub stars
- 9,346
- License
- Apache-2.0 or MIT
- Works with
- Claude Code, Codex, Copilot CLI, Gemini CLI, OpenCode, Kiro, Droid, Amp, Pi
- What it adds
- A hook and commands that open plans and diffs in a browser review page
Security Guidance
Checks Claude's own code for security holes at three points: pattern warnings as it edits, a model review of the diff when a turn ends, and a deeper review on git commit. Kev Gary of Claude Camp calls it non-negotiable if you don't read every diff. Older guides describe only the edit-time hook. The diff review runs on the newest Opus by default, which uses your plan or API credit, and it needs Python 3.8 or newer.

- Works with
- Claude Code 2.1.144 or newer, with Python 3.8+
- What it adds
- Hooks: edit-time warnings, a diff review each turn, a commit reviewer
Compound Engineering
Every's plugin of 36 skills built around one loop: brainstorm, plan, build, review, then write down what you learned so the next change can read it. Hacker News commenters single it out as one of the few third-party skill sets worth installing. It is slow on purpose, and one user notes it can take many minutes between prompts while it explores.
- Install

- /plugin marketplace add EveryInc/compound-engineering-plugin
- GitHub stars
- 25,483
- License
- MIT
- Works with
- 14 agent hosts, including Claude Code, Cursor and Codex
- What it adds
- 36 skills for a brainstorm, plan, build, review and capture loop
claude-mem
Records what Claude does in each session and feeds the relevant parts into the next one, so you stop re-explaining the project. Samanvya Tripathi says it is the plugin he would keep if he could keep only one. Two catches: it only remembers from the day you install it, and the npx installer asks you to sign in and starts a 30-day trial of a hosted service that costs $30 a month if you subscribe. The local engine stays free.
- Install
- /plugin install claude-mem
- Marketplace
- /plugin marketplace add thedotmack/claude-mem
- Paid option
- CMEM Pro hosted memory, $30/month after a 30-day trial; local engine free
- GitHub stars
- 99,811
- License
- Apache-2.0
- What it adds
- Hooks and a local worker that save and re-inject session memory
context-mode
Runs bulky tool calls in a sandbox and passes back only what was asked for, so a huge browser snapshot or git log never fills the context. Tim Schipper ran it for weeks and prefers it to the far more starred Caveman because it shrinks the biggest source of tokens. He also warns of setup friction around Node versions and native SQLite. The license is Elastic 2.0, which is not an open-source license.
Claude HUD
A status line that sits under the prompt and shows how full the context window is, your rate limits and, if you turn them on, running tools, subagents and todos. Tony Lee, who used it for a few weeks, calls the context bar the reliable part and says tool status can go stale when calls overlap. Setup needs one extra command after installing, /claude-hud:setup.
- Install
- /plugin install claude-hud
- Marketplace
- /plugin marketplace add jarrodwatts/claude-hud
- GitHub stars
- 28,464
- License

- Works with
- Claude Code only
- What it adds
- A status line: context used, rate limits, tools, agents and todos
Commit Commands
Three slash commands for the dull part of git: /commit writes a message in your repo's style, /commit-push-pr goes all the way to a pull request, and /clean_gone clears local branches whose remotes are gone. Mejba Ahmed calls it small, boring and used constantly. The pull request command needs the GitHub gh CLI installed and signed in, and commits carry a Claude Code attribution line.

- Maintainer
- Anthropic
- Works with
- Claude Code; pull requests need the gh CLI
- What it adds
- Slash commands: /commit, /commit-push-pr and /clean_gone
Feature Dev
A /feature-dev command that walks through seven phases, from clarifying questions and codebase exploration by parallel agents to architecture, build and review. In Jenny Ouyang's test on a real app it removed four database tables from the design before any code was written. Augusteo skips it for small changes, and Mejba Ahmed finds it sits idle in maintenance weeks.

- Anthropic
- Works with

- What it adds
- A /feature-dev command and explorer, architect and reviewer agents
Code Review
Runs /code-review on a pull request: four agents check it in parallel, each finding gets a confidence score, and only those at 80 or above are posted as a comment. Augusteo runs it on his own work before committing. Riddam Jain found he had never once invoked it, because Claude Code has a built-in review command too and he had been crediting the plugin for the built-in's work.

- What it adds
- A /code-review command that runs four review agents on a pull request
Codex plugin for Claude Code
OpenAI's own plugin, which lets Claude Code hand a review or a stuck task to Codex without leaving the session. People use it for a second opinion from a different model: ilia-a on Hacker News reports surprisingly many findings, and Mejba Ahmed says a spot both models flag is nearly always real. You need a ChatGPT account or an OpenAI API key, and the usage counts against your Codex limits.
Hookify
Turns a sentence such as "warn me when I use rm -rf" into a hook, saved as a small markdown rule that takes effect on the next tool call. Run with no arguments, it reads the conversation for things you corrected. Edi, a blogger running 39 automation jobs, adds a guard rule with it after each incident. Rules are regex patterns, so they catch only what you thought to describe.

- License

- Maintainer
- Anthropic
- Works with

- What it adds
- A /hookify command that writes warn or block hooks as markdown rules
CC Safety Net
A hook that reads each shell command before it runs and blocks the destructive ones, such as git reset --hard, force pushes and rm -rf on your home folder, even when wrapped in bash -c. It was called claude-code-safety-net until a rename, and it now installs through an npx command that adds its own marketplace. The maker says plainly that it is not a sandbox. Outside recommendations are few so far.

- What it adds
- A PreToolUse hook that blocks destructive commands and secret-file reads
How to choose
A plugin is a bundle. One install can carry skills, slash commands, subagents, hooks and MCP servers. A skill is a single instruction file Claude loads when it judges it relevant, and an MCP server is a connection to an outside tool, so a plugin can contain both. Type /plugin inside Claude Code to browse Anthropic's official marketplace, which is connected from the start, or run /plugin install name@claude-plugins-official. For anything else, add the maker's marketplace first with /plugin marketplace add owner/repo.
If you install one thing, make it Superpowers, plus the LSP plugin for your language. Add Security Guidance if you ship code you don't read line by line, Plannotator if you want to mark up plans in a browser, and Claude HUD to see how full the context is.
Every enabled plugin adds to the context on every turn, and several of the writers quoted here deleted more than they kept. Plugins run code on your machine with your permissions, and community marketplaces are not reviewed, so read what a plugin will install before you say yes. Two names trip people up. Claude Code has a built-in review command alongside the Code Review plugin. And Anthropic keeps a second, smaller marketplace in the anthropics/claude-code repo, where the loop plugin still goes by ralph-wiggum and not ralph-loop.
The list is ordered by how many independent people recommend each plugin, then by installs and GitHub stars.

Best Wispr Flow Alternatives (2026)
The best Wispr Flow alternatives: dictation apps that type into any app, for people leaving over price, cloud processing or platforms, picked from tests by 9to5Mac, ZDNet, Zapier and others. Leaving over price? Handy and FluidVoice are free, Chirp is $9.99 a year, VoiceInk is $25 once for a Mac, and Aqua Voice Pro is $8 a month billed yearly against Wispr Flow's $12. For privacy, Superwhisper, Handy, FluidVoice, VoiceInk, Spokenly and Chirp can transcribe without your audio leaving the computer, while Aqua and Typeless are cloud services like Wispr. On Linux, try Handy, Spokenly or Typeless. On Android, Typeless or Superwhisper. Accuracy depends on the model as much as the app: in Voice-list's test, Superwhisper's own models ranged from 1.6% to 22.8% of words wrong, so try another model before giving up on an app. Free tiers differ too. Aqua's is 1,000 words in total, Willow's free plan uses a lighter model, and Superwhisper's never runs out. Ordered by wins in named tests and how many independent reviewers recommend each app, then by how well it fixes the usual reasons for leaving Wispr Flow (price, privacy, platforms), then by price. Disclosure: Chirp is made by the team behind Listicle. We placed it ourselves, as the budget pick, and no independent reviewer has tested it yet. Everything else follows the order above.

Best Clipboard Managers for Windows (2026)
The best clipboard managers for Windows 10 and 11, for anyone who has outgrown Win+V, ranked on hands-on tests by MakeUseOf, XDA, How-To Geek and others. Ordered by test wins and how many independent reviewers recommend each app, then by price, with Windows' own clipboard history included as the baseline. Pasta has no independent reviews yet, so it ranks below the apps that do. Win+V keeps 25 items and forgets them on restart unless you pin them. Ditto fixes both for free and won head-to-head tests at MakeUseOf and XDA. For more, CopyQ adds tabs and scripting, ClipClip adds an editor and OCR, and Pasteboard is the simplest modern-looking choice. Already using Raycast as a launcher? Its clipboard history is free and searchable. Most picks are free at home but not at work: ClipClip charges $49 for commercial use, ClipboardFusion's free version is for personal use only (Pro starts at $19 per PC), and Clipdiary's business license is $29.99. If you also use a Mac, Raycast and CopyQ run on both. Disclosure: Pasta is made by Automatique, the team behind Listicle; it's rated by the same criteria as everything else. Prices checked October 5, 2026.
Best Clipboard Managers for Mac (2026)
The best clipboard managers for Mac, from free apps to the history built into macOS Tahoe, ranked on hands-on tests by Zapier, MacStories, Six Colors and others. Ordered by test wins and how many independent reviewers recommend each app, then by price, with Spotlight's built-in history included as the free baseline. Pasta has no independent reviews yet, so it ranks below the apps that do. To choose, try Tahoe's Spotlight history first (Command-Space, then Command-4). If a week of history isn't enough, Maccy is the free step up, Paste is the one to get if your clipboard should follow you to an iPhone, and Pastebot suits people who reshape text as they paste. Already use Raycast, Alfred, LaunchBar or Keyboard Maestro? Try the history it already has before buying anything. Subscription or one payment? Paste costs $29.99 a year, while PastePal ($14.99), ClipBook ($9.99) and CopyClip 2 ($7.99) are one-time buys, and of those three only PastePal syncs with an iPhone. Pastebot sits in between: $39 up front, then $19 for each further year of updates. Disclosure: Pasta is made by Automatique, the team behind Listicle; it's rated by the same criteria as everything else. Prices checked October 5, 2026.
Best AI Task Managers (2026)
The best AI task managers, where the AI does real work from planning your day to running agents on a board, picked from hands-on tests by Wirecutter, PCMag, Zapier and others. Match it to how you work. If you want AI to plan your day, Sunsama walks you through a daily plan, Reclaim fits tasks around your meetings and has a free plan, and Motion plans and reshuffles your whole calendar. If you want a fast list with a little AI, start with Todoist. Teams should try Asana first, ClickUp if they want everything in one app, or Notion if their work already lives in docs. Software teams belong in Linear. On a budget: Todoist Pro and Reclaim Starter together come to about $15 a month billed yearly and put your Todoist tasks on your calendar, less than Motion's $19 alone. Google Gemini schedules tasks into Google Calendar for free. Watch the AI add-ons: ClickUp's Brain AI costs $9 a user on top of the plan, Notion's agents need the $20 Business plan, and Motion, Asana and monday.com meter AI with credits or request limits. Ordered by wins in named hands-on tests, then by how many independent reviewers recommend each app, then by fit for individuals and small teams and by price. Disclosure: Wand is made by Automatique, the team behind Listicle; it's rated by the same criteria as everything else. Prices checked October 5, 2026.
Best AI Story Writing Apps (2026)
The best AI story writing apps, from drafting partners like Sudowrite to manuscript critics like ProWritingAid, ranked on reviews by Kindlepreneur, Reedsy, The Write Practice and others. Match the tool to the job. To draft with an AI partner, Sudowrite works out of the box, while Novelcrafter gives you more control if you bring your own AI key. To revise, ProWritingAid catches line-level problems, Fictionary checks scene structure and Marlowe sends a whole-book report. For brainstorming or notes on a full draft, a general chatbot works: Claude for prose, ChatGPT for features, Gemini for very long manuscripts. On cost: Raptor Write is free and you pay only for the AI you use, and Gemini's Plus plan is $4.99 a month. Sudowrite's Hobby plan and ProWritingAid Premium together come to about $20 a month on yearly billing. Most of these meter AI use in credits or tokens, so heavy drafting can cost more than the plan price. Ordered by how many independent reviewers tested or recommended each app, then by how well it suits writing your own fiction, then by price. Disclosure: Fable is made by Automatique, the team behind Listicle; it's rated by the same criteria as everything else. Prices checked October 5, 2026.
Best Claude Skills (2026)
The best Claude skills are the SKILL.md packages that Hacker News users and independent reviewers keep recommending. This list ranks collections and single skills you can install today, with what each adds and its catch. If you want Claude to plan and test before it codes, get Superpowers. If you want it to question you before it starts, get grill-me from Matt Pocock's skills. For better-looking pages, start with frontend-design and add Impeccable to review the result. To build your own skills, or to make real Word, Excel, PowerPoint and PDF files, use Anthropic's repository. For marketing work, use Corey Haines's pack. Skills install in three ways. In Claude Code, run /plugin install from a marketplace, or copy a folder into ~/.claude/skills. For most coding agents, npx skills add owner/repo does the copying. In the Claude apps, upload a ZIP under Customize > Skills. Skills follow the open Agent Skills format, so most of these also run in Codex, Cursor and Gemini CLI. Older guides are now wrong in places. Claude Code has merged custom commands into skills. Superpowers and Matt Pocock's skills are in Anthropic's official marketplace, so adding a separate marketplace is no longer needed. The Karpathy repository moved to a new owner. Star counts are huge and say little, and a link list such as awesome-claude-skills installs nothing. A skill is instructions plus scripts that run with your agent's permissions. Snyk scanned 3,984 skills from ClawHub and skills.sh and found a critical security issue in 13.4% of them. Read a skill before you install it, and install a few, not all. Items are ordered by how many independent people recommend each one, then by GitHub stars. Everything here is free.
