Catalog

This is the shopping list. Skills, Plugins, MCP & LSP explains what these things are; this page is what to install and reach for. It covers how plugins arrive from a marketplace, every plugin this team actually runs — grouped by the job it does — and a quick router for picking the right one under pressure.

Who this is for. Engineers setting up their machine or deciding which tool fits the task in front of them. If a term here is unfamiliar (skill, MCP, LSP, subagent), the previous page defines it.

The plugins this team runs, and which one to reach for — 2 min 9 s.

Installing plugins from a marketplace

A marketplace is a catalog of plugins (often a GitHub repo). The flow:

# Add a marketplace (Anthropic's official one is registered automatically on first launch)
claude plugin marketplace add anthropics/claude-plugins-official

# Browse and install interactively
/plugin

# …or install a specific plugin
/plugin install superpowers@claude-plugins-official

After installing, run /reload-plugins to pick up skills, agents, hooks, and servers without restarting. To develop or test a local plugin, launch with claude --plugin-dir ./my-plugin. This team also has a couple of non-default marketplaces registered (the OpenAI Codex marketplace openai/codex-plugin-cc, and supermemoryai/claude-supermemory).

This team's installed plugins

Every plugin below is actually installed and enabled in this setup. Use the "reach for it when" column as a quick router.

Workflow

Plugin What it provides Reach for it when
superpowers (claude-plugins-official) A suite of workflow skills: brainstorming, writing-plans, executing-plans, subagent-driven-development, test-driven-development, systematic-debugging, using-git-worktrees, requesting-code-review, receiving-code-review, verification-before-completion, dispatching-parallel-agents, finishing-a-development-branch, writing-skills You want a disciplined, reviewable process instead of vibe-coding. Deep-dived in Superpowers and Workflows.
ralph-loop (claude-plugins-official) Runs a prompt or slash command repeatedly on a loop (/ralph-loop, /cancel-ralph) A task needs the same prompt applied iteratively until a condition is met (polling, repeated passes).
skill-creator (claude-plugins-official) Create, edit, optimize, and eval custom skills You've repeated a workflow enough times to package it. See Reusable Skills and Automation.

Review and quality

Plugin What it provides Reach for it when
code-review (claude-plugins-official) /code-review — reviews a PR or your current working diff for correctness and quality Before merging, or to get a second read on a change you just made.
codex (openai-codex) Delegates a task to OpenAI's Codex/GPT through a shared runtime as a second opinion or rescue pass (/codex:rescue, /codex:setup, codex-rescue agent) Claude is stuck, or you want an independent model to diagnose, implement, or adversarially review.
code-simplifier (claude-plugins-official) Simplifies recently changed code for clarity and consistency without changing behavior After a feature lands and you want to tidy it — quality only, not bug hunting.
claude-md-management (claude-plugins-official) Audits and improves CLAUDE.md files (/revise-claude-md, claude-md-improver) Your project memory has drifted, grown stale, or needs a quality pass.

codex here is the plugin, not the standalone CLI. This entry runs Codex inside Claude Code as a delegated helper. Codex also ships as its own standalone terminal agent you'd run instead of Claude Code — covered, alongside OpenCode, in Codex and OpenCode.

Docs and knowledge

Plugin What it provides Reach for it when
context7 (claude-plugins-official) MCP server that fetches current docs for a library/framework/SDK by name You're using a library where the model's training data may be out of date. Prefer this over guessing API syntax.

Security and audit

Plugin What it provides Reach for it when
entry-point-analyzer (trailofbits) Finds state-changing entry points in smart contracts and categorizes them by access level Auditing Solidity/Vyper/Solana/Move/CosmWasm contracts; mapping external functions and privileged operations.
ask-questions-if-underspecified (trailofbits) Forces clarifying questions before implementing when requirements are ambiguous A task is underspecified and guessing would be expensive.

From the Trail of Bits marketplace. Both plugins above come from Trail of Bits' security-focused skills marketplace — trailofbits/skills — not the official catalog. It ships more than these two; if you do security or smart-contract work, browse the whole set (see also Further Reading).

Beyond this team's set. The official catalog and Trail of Bits aren't the whole world of skills. Practitioners publish their own — mattpocock/skills is a strong, model-agnostic collection for everyday engineering (aligning with the agent, domain modeling, TDD, review), and everyinc/compound-engineering-plugin packages the compounding-workflow idea from Reusable Skills and Automation. Browse them for patterns to adapt, not just to install wholesale.

Language servers (LSP)

Plugin What it provides Reach for it when
typescript-lsp (claude-plugins-official) Real TypeScript language-server diagnostics Working in TS/JS and you want type errors caught precisely, not approximated.
pyright-lsp (claude-plugins-official) Pyright diagnostics for Python Python projects — type checking and symbol resolution.
rust-analyzer-lsp (claude-plugins-official) rust-analyzer diagnostics Rust projects.

Why LSP plugins matter. They give Claude the same real-time diagnostics your IDE shows — go-to-definition, type errors, unused symbols — instead of inferring them from text. Fewer hallucinated APIs, faster correct fixes.

App-building

Plugin What it provides Reach for it when
agent-sdk-dev (claude-plugins-official) Scaffolds and verifies Claude Agent SDK apps (/new-sdk-app, plus TS/Python verifier agents) Building your own agent on top of Claude Code's engine. Pairs with Integrating AI via API.
frontend-design (claude-plugins-official) Guidance for distinctive, intentional UI design Building or reshaping UI and you want it to not look templated.

Misc / commerce

Plugin What it provides Reach for it when
stripe (claude-plugins-official) Stripe integration guidance, an MCP server, and skills (test-cards, explain-error, stripe-best-practices, Connect helpers) Building or reviewing any Stripe payments integration.
