Gives agents a live local Excalidraw canvas: add, edit and delete elements to draw architecture diagrams and flowcharts, take screenshots to check the result, convert Mermaid and export .excalidraw files. Runs locally with no API key; also ships a CLI and an agent skill.

Gives agents on-demand guidance for the modern web platform, covering View Transitions, container queries, Popover, INP optimization, accessibility and more, with browser compatibility data so they avoid outdated code. Maintained by the Google Chrome team; currently in preview.

Runs open image models like FLUX, Qwen Image and Z-Image locally on a Mac: text-to-image, reference-based edits, inpainting and upscaling, all on-device. Needs Apple Silicon and uv; the first run downloads models and is slow. Check each model's license before commercial use.

65 skills built on methods from business, marketing and design bestsellers like Influence, StoryBrand and The Lean Startup: positioning, copywriting, conversion optimization, sales negotiation, UX review, plus step-by-step startup and site-building guides. Prompt-only, no API key needed.

Four tools for real-time web search, page content extraction, site mapping and full-site crawling, available as a remote server or run locally. Maintained by Tavily; needs an API key or OAuth sign-in, and a free account is available.

Supabase's official CLI: runs the full backend stack locally (Postgres, Auth, Storage, Edge Functions), manages database migrations, generates types and deploys functions. The local stack requires Docker.

Terraform and OpenTofu best practices from Anton Babenko: diagnoses the failure mode first, then guides testing, module structure, state management, CI/CD and security scanning. Works for AWS, Azure and GCP.

Two-stage deep research: drafts an editable outline for the topic, then parallel subagents search the web item by item and compile a Markdown report. Good for literature reviews, competitor research and due diligence. Install by copying files per the README, plus pip install pyyaml.

Uses hooks to enforce test-driven development in Claude Code: blocks implementation without a failing test, prevents code beyond what tests require, and can use lint results to push refactoring. Needs Node.js 22+. Still maintained, but the author suggests its successor Probity for new projects.

A video production workspace for Claude Code: scripting, AI voiceover, music, generated visuals and Remotion rendering to MP4, with explainer and product-demo templates. The full workflow needs the cloned repo and Node.js 18+; AI generation needs your own cloud GPU (e.g. Modal's free tier).

Lets Claude Code and other agents call Antigravity CLI or Gemini CLI, using Gemini's large context window to analyze big files and whole codebases; with Gemini CLI it can also test code in a sandbox. Install and sign in to the CLI first. Not an official Google project.

WordPress's official skill collection: block development, block themes, plugin architecture, REST API, Interactivity API, WP-CLI, performance profiling and Playground, so agents write code to modern WordPress standards and avoid common security pitfalls.

Draws a code change or part of a codebase as an animated architecture or data-flow diagram. The agent writes a JSON graph, validates and renders it to SVG with the PR Lens CLI, then pushes it to a prlens.dev canvas or attaches it to a GitHub, GitLab or Bitbucket pull request.

Explains a codebase, feature, command or pull request to someone new to it as a PR Lens canvas: one plain sentence first, then a walkthrough that grows the diagram from two boxes to the whole picture, delivered as a shareable link. Requires the PR Lens skill and its npx CLI.

Stripe's official CLI: forward and trigger webhook events locally, tail API request logs in real time, and create, read, update or delete Stripe objects to debug payment integrations. Needs a Stripe account; run stripe login first.

Exports Feishu/Lark docs, whole folders or wikis to Markdown with images, so agents can read, migrate or archive them. Requires creating a custom app on the Feishu/Lark Open Platform and configuring its App ID and App Secret.

MiniMax's official CLI, built for agents: chat with MiniMax models from the terminal and generate images, video and speech, plus speech transcription, image understanding and web search. Works with the international platform. Requires a MiniMax Token Plan subscription.

A CLI and Python library by Simon Willison: imports JSON and CSV straight into SQLite with automatic table creation, runs in-memory SQL queries over files, and supports full-text search and table transformations.

A native Go MCP server for Kubernetes and OpenShift: talks to the API server directly to create, read, update and delete any resource, view pod logs, exec commands and install Helm charts, without needing kubectl. Supports multiple clusters.

Translation management for Ruby/Rails: statically analyzes code to find missing and unused keys, normalizes locale files, fills gaps via Google Translate, DeepL or OpenAI, and exports CSV for translators. Requires the i18n gem (Rails default) and Bundler; machine translation needs an API key.

Figma's official skill that teaches agents to run Plugin API scripts via use_figma, creating and editing nodes, components, variables and auto layout directly on the canvas. Load it before any use_figma call. Needs a Figma account and the remote MCP server.

Figma's official skill: the agent writes Mermaid, then uses the Figma MCP to build flowcharts and sequence, state, Gantt and ER diagrams in FigJam for you to tweak by hand. Unsupported types like pie charts and mind maps are flagged upfront. Needs a Figma account and the remote MCP server.

Figma's official skill for building FigJam boards through the Figma MCP: sticky notes, sections, connectors, shapes and tables for brainstorms, retros and meetings. Needs a Figma account, the remote MCP server and the figma-use skill; canvas writes are free in beta; usage pricing is planned.

The Linux Foundation's open-source compliance toolchain: analyzes project dependencies, scans licenses and copyrights, checks known vulnerabilities, flags policy violations and generates SBOMs and notice files. Needs Java 25 or Docker and ideally 8 GB RAM; have legal review license findings.
