Tools

21st.dev's official MCP: lets agents search and fetch UI components, themes and template code from the 21st.dev community, and generate components from a description once AI access is enabled. Absorbs the former Magic MCP; requires a free API key from 21st.dev.

Veteran suite of CSV command-line tools: in2csv converts Excel and JSON to CSV, csvcut, csvgrep and csvsort filter and sort, csvstat computes statistics, and csvsql runs SQL directly against CSV files.

A prose linter that checks docs against style guides: use ready-made packages like Microsoft and Google or write your own YAML rules. It parses Markdown, AsciiDoc and other formats before checking, runs fully offline, and plugs into editors and CI.

Google's official skills for building ADK agents: dev workflow, scaffolding, the ADK Python API, evaluation with LLM judges and adaptive rubrics, deployment to Agent Runtime, Cloud Run or GKE, publishing and observability. Works with agents-cli; local dev needs only an AI Studio key.

In-chat fallback for the transitions.dev Timeline Inspector's Refine button: the agent long-polls a local relay and answers jobs with motion-token tweaks or a full transition recipe swap, and applies accepted changes. Idle polling costs credits, so the persistent CLI mode is preferred.

Polishes existing motion against the transitions.dev token scale for duration, distance, scale, blur and easing, matching each value by what the motion does rather than the nearest number, with rules for open/close asymmetry, hover in and out, stagger and intent delays.

Local neural text-to-speech engine that converts text to speech offline, with voices in dozens of languages, handy for listening materials or narrating articles and course slides. Needs Python; download a voice model before first use. The project is currently looking for maintainers.

Fixes defensive academic writing full of hedging and preemptive disclaimers, organizing abstract, introduction, experiments and conclusion around your strongest contribution. Also helps trim length and self-check before a rebuttal. English and Chinese versions, plus a prompt for any AI chat.

Posit's open-source scientific and technical publishing system built on Pandoc: embed Python, R or Julia code in Markdown or Jupyter notebooks, then quarto render produces HTML, PDF, Word, slides, websites and books.

The .NET team's official skill collection, grouped into plugins: ASP.NET Core, Blazor, MAUI, EF Core data access, MSBuild troubleshooting, performance diagnostics, testing, and framework upgrades and migrations. Maintained by Microsoft; install via the Claude Code or Codex plugin marketplace.

Veteran command-line task manager with projects, tags, priorities, due dates and custom reports, JSON export, and a rich ecosystem of hooks and extensions, well suited for agents that record and track tasks.

Docker's official CLI for building images, running and managing containers, viewing logs and pushing to registries, a foundational tool for agents setting up isolated environments. Needs a local or remote Docker Engine such as Docker Desktop.

Community-maintained MCP for Jira and Confluence: search with JQL/CQL and create or update issues, pages and comments. Supports both Cloud and Server/Data Center deployments; needs an API token or personal access token.

Applies Anthony Fu's conventions for JavaScript and TypeScript projects: file organization, explicit imports, Vitest style, @antfu/ni, @antfu/eslint-config with antislop, Knip, tsdown and a single ci script, mirroring the antfu/starter-ts template for new projects.

Reference for Nuxt 5, the full-stack Vue framework: directory layout, file-based routing, useFetch, auto-imports, server routes, rendering modes, SSR and hydration pitfalls, modules and layers, with notes on the move to Nitro v3 and Vite 8. Generated by Anthony Fu from the official docs.

Reference for UnoCSS, the atomic CSS engine: config, rules, shortcuts, theme and variants, presets like Wind3, Wind4, Icons and Attributify, and Vite and Nuxt setup. Tells the agent to check uno.config first and stick to plain classes when unsure. Generated by Anthony Fu from official docs.

Full-featured Jira CLI: filter, create, transition, assign and link issues and manage epics and sprints, with --plain text output that agents can read. Works with Cloud and self-hosted Jira; set up an API token and run jira init.

Reference for VitePress 2, the Vite and Vue static site generator for docs: file routing, Markdown extensions and Vue in Markdown, data loaders, dynamic routes, theme config and custom themes, i18n, SSR compatibility and deployment. Generated by Anthony Fu from the official docs.

Reference for pnpm 12: CLI, pnpm-workspace.yaml settings, monorepo workspaces, catalogs, overrides, patches, supply-chain settings such as build approval, task orchestration, CI setup and migration from npm, Yarn or older pnpm. Generated by Anthony Fu from the official docs.

Reference for Nitro v3, the server toolkit behind Nuxt: file routes with H3 v2 handlers, route rules, caching, KV storage, tasks, WebSockets and OpenAPI, plus deploy presets and v2 migration notes. Generated by Anthony Fu from the official docs.

Reference for Pinia v4, Vue's official state library: defining stores with state, getters and actions, plugins, composables, composing stores, testing with @pinia/testing, SSR, Nuxt and HMR. Recommends setup stores and storeToRefs. Generated by Anthony Fu from the official docs.

Zero-config CLI that sets up Claude Code and Codex in one go: an interactive menu handles installation, workflow imports, API and CCR proxy setup and common MCP servers, with model provider presets and bilingual English/Chinese configuration.

Reference for Vue 3.5: script setup and macros such as defineProps, defineEmits and defineModel, reactivity, watchers and lifecycle, and built-ins like Transition, Teleport, Suspense and KeepAlive. Prefers the Composition API with TypeScript. Generated by Anthony Fu from the official docs.

Reference for Vite 8: vite.config.ts, features like import.meta.glob and asset queries, the plugin API, library mode and SSR, the Environment API, and migrating to the Rolldown bundler and Oxc transformer. Prefers TypeScript config and ESM. Generated by Anthony Fu from the official docs.
