Marketing OS

Marketing Skills is a collection of Markdown-based skills for AI coding agents, built by Corey Haines. It provides specialized workflows for conversion optimization, copywriting, SEO, analytics, advertising, growth engineering, sales, and related marketing tasks, and supports Claude Code, OpenAI Codex, Cursor, Windsurf, and agents implementing the Agent Skills specification. The skills share context and cross-reference one another. The product-marketing skill serves as the foundation, with other skills consulting it for product, audience, and positioning information before handling tasks such as CRO, copywriting, SEO audits, analytics setup, email flows, pricing, or sales enablement. Skills can be installed individually or as a collection through the Skills CLI, Claude Code's plugin system, a repository clone or submodule, or SkillKit. The repository is built and maintained through community contributions, with issues and pull requests welcomed. It is free and MIT-licensed.

An open-source marketing-agent team from Vercel Labs built on the eve framework. Users submit launch planning, copywriting, or SEO requests through Slack or the eve terminal TUI; a lead agent loads the shared brand-context document, writes a self-contained brief, routes it to one of five specialists—product marketing, content marketing, social media, SEO, or email—and returns the resulting deliverable. The lead does not write deliverables itself, and specialists work independently without shared conversation history; the product marketer alone maintains the brand-context document, which the other specialists read at the start of a task. Newsletter work passes from the content marketer to the email specialist for inbox adaptation and sending. Outputs are delivered through Notion, Typefully, Resend, or stored audit artifacts. The system pauses irreversible operations—including Resend sends and deletes, Typefully deletes and scheduled publishing, and Notion page moves—for approval in Slack or the terminal; its email specialist is restricted to an allowlist of Resend tools. Deployment provisions Notion, Resend, and Slack connectors and a Vercel Blob store, and requests a Typefully API key. The implementation uses TypeScript, Vercel Connect, MCP connections for Notion, Typefully, and Resend, Vercel AI Gateway for model access, and Vercel Sandbox for reference files and shell commands. Email campaigns require a verified Resend sending domain and at least one segment configured in Resend.

Awesome Claude Skills is a curated GitHub resource covering reusable Claude Skills, plugins, tools, and related resources for Claude.ai, Claude Code, the Claude API, and other coding agents such as Codex, Cursor, Gemini CLI, Antigravity, and Windsurf. It organizes examples by areas including document processing, development, data analysis, communication, media, productivity, project management, security, and SaaS-app automation through Composio. The repository explains Skills as folders containing a SKILL.md file with YAML metadata and Markdown instructions, optionally accompanied by scripts, references, and assets. It documents progressive loading: agents initially see a skill's name and description, load the full instructions when relevant, and load supporting files on demand. It also distinguishes Skills, which define workflows and guardrails, from MCP servers and tools, which provide system access and individual actions. The list accepts contributions through documented quality and pull-request guidelines. The repository is licensed under Apache 2.0, while individual skills may use different licenses.

AI Copywriter is a portable, plain-Markdown agent skill for writing marketing copy and removing common patterns associated with AI-generated prose. It supports headlines, short descriptions, microcopy, subject lines, button labels, and LinkedIn posts, and runs in any harness that supports skill-style instructions. Before drafting, it interviews the user about the intended customer, product category, and underlying story, then pressure-tests the story for specific and interesting details. Its copywriting method focuses on the reader's immediate situation and explains the product in simple language. It incorporates the 33 detectable and fixable writing patterns from blader's Humanizer while adding the reverse workflow of generating marketing copy designed around those constraints.

Anthropic's repository of Agent Skills for Claude, including example skills, the Agent Skills specification, and a template for creating custom skills. Each skill is a self-contained folder with a SKILL.md file containing metadata and instructions that Claude loads dynamically for specialized tasks such as document creation, data analysis, web-app testing, MCP server generation, and communications workflows. The repository's skills can be installed as Claude Code plugins, used in Claude.ai, or accessed through the Claude API. It includes document, PDF, presentation, and spreadsheet skills used in Claude's document capabilities; many examples are Apache-2.0 licensed, while those document-creation skills are source-available rather than open source. The repository presents the implementations for demonstration and educational purposes and notes that their behavior may differ across Claude environments.
