A free pack of instruction files that teach an AI agent marketing work such as conversion reviews, copy, SEO, ads, email, and launch planning. It is built for Claude Code, Codex, Cursor, and other agents that can read the Agent Skills format.
“Use the copywriting and CRO skills to rewrite my homepage hero so a first-time visitor can tell what we sell without scrolling.”
Corey Haines publishes this as a library of marketing skills. The README says product-marketing is the foundation the other skills read first, and then lists skills for SEO, conversion, copy, paid ads, email, lifecycle, pricing, sales enablement, and related work.
The recommended install is the skills CLI: npx skills add coreyhaines31/marketingskills. You can install the whole library or name specific skills. The CLI asks which agent to install for. The README warns that running it from inside an agent session can land the files where Claude Code will not read them unless you pass the agent explicitly.
The project is MIT licensed. Partner tools are disclosed in the README. Those partners are not required to use the skills, and this directory does not evaluate them.
Skill
An Anthropic skill that restyles artifacts with Anthropic's own colors and fonts, including Poppins for headings and Lora for body text when those fonts are installed. It is Anthropic's look, not a way to load your company's brand.

MCP server
Firecrawl's official server lets an agent search, scrape pages into clean text, map a site, crawl, and interact with a page. A keyless hosted tier can search, scrape, and parse within limits; crawl, map, and the research agent need an API key.

MCP server · Starting point
HubSpot hosts an MCP server at mcp.hubspot.com so an AI tool can read and update CRM data with the signed-in person's existing permissions. The GitHub repository at the source link is empty, so this entry follows HubSpot's own docs rather than code in that repo.
