Anthropic's public repository of skills for Claude: folders of instructions, scripts and resources that teach it repeatable tasks. It spans design, communications and documents, including the skills Claude uses to create and edit Word, PowerPoint, Excel and PDF files.
Our takeStart here before building your own. Use the brand-guidelines skill as a template for a client's colours and type, and skill-creator to write and test new skills.
Anthropic's marketplace of plugins for Claude. Each plugin bundles tools, skills and integrations for one-click installation, from Marketing, Brand Voice and Design plugins to ones from Adobe, Slack and Dropbox.
Our takeStart with the Marketing and Brand Voice plugins and feed them each client's guidelines and terminology. Install plugins only from developers you trust.
A free, MIT-licensed library of marketing skills for AI agents by Corey Haines, covering conversion optimisation, copywriting, SEO, paid ads, analytics and launches. It works with Claude Code, Codex, Cursor and other agents that support the Agent Skills spec.
Our takeBest for growth teams comfortable in a terminal. Run the product-marketing skill first to record product, audience and positioning, which the others read; several assume a SaaS product.
OpenAI's curated collection of plugins for Codex. A plugin can bundle skills, app connections and commands; creative ones include OpenAI's Creative Production and plugins from Adobe and Canva, and others connect to Figma, Notion and Google Slides.
Our takeWorth a look if your team uses Codex: Creative Production turns a brief or product image into ad directions, mood boards and social posts. Canva's plugin needs a Canva account.
Anthropic's official guide to prompting Claude: when prompt engineering is the right fix, how to approach it, and a best-practices page on clear instructions, examples, XML structure, role prompting and prompt chaining. It also links to interactive tutorials.
Our takeWritten with developers in mind, but anyone can go straight to the best-practices page: the same habits sharpen any brief you give Claude.
OpenAI's free, self-paced courses on using AI at work, from AI Foundations to agents, workflows and AI leadership, alongside technical tracks for developers. Passing a course assessment earns a badge.
Our takeNon-technical teams should start with AI Foundations, then Agents and Workflows. You can browse without signing in but need a ChatGPT account to enrol.
Google's guide to Gems in the Gemini app: how to build a custom Gem in the web app with your own instructions and knowledge files, and where to find premade Gems such as Brainstormer and Writing editor.
Our takeSet up one Gem per client with its brand guidelines as knowledge files, so every chat starts from the same brief. Let Gemini rewrite your instructions before you save.
