Who marketingskills is for#

Technical founders using AI coding agents for product development

A founder already using Claude Code for engineering work can install marketingskills and ask the same agent to run a CRO audit, draft a cold email sequence, or produce a competitor analysis without switching to a separate marketing AI tool. The product-marketing skill anchors every task to the same product context.

Skip if:

The team has a dedicated marketing hire who prefers purpose-built tools with visual interfaces. In that case, a managed platform like Jasper AI or Copy.ai is a better fit for non-technical users.

Technical marketers building SEO and analytics pipelines

The seo-audit, ai-seo, programmatic-seo, schema, and analytics skills give an agent structured frameworks for SEO and measurement tasks. A technical marketer can run these inside their coding environment alongside the code changes they produce, without switching contexts.

Skip if:

Your SEO work is primarily strategic or editorial rather than technical. Non-technical SEO workflows are handled better by dedicated SEO SaaS tools with visual reporting and dashboards.

Growth teams setting up repeatable marketing loops

The marketing-loops skill is designed for recurring, self-running marketing workflows. A growth team can wire up repeatable loops that an AI agent runs on a schedule, applying consistent frameworks across content creation, outreach, and analysis tasks.

Skip if:

Your team needs visual workflow builders, no-code automation, or approval flows with non-technical stakeholders. Marketing automation platforms handle those collaboration requirements better than a local skill library.

the problem

The problem it solves#

Technical marketers and founders using AI coding agents run into a consistent pain: the agent is effective at code but treats every marketing task as a blank-slate conversation. Each time you need a CRO audit, a cold email sequence, or an SEO analysis, you rewrite context from scratch, and output quality depends on how well you framed the prompt that session.

The deeper problem is fragmentation. SEO, copywriting, paid ads, analytics, and growth loops each need different frameworks, but most teams have no way to hand that structured knowledge to an agent consistently. Product positioning gets re-explained every session rather than loaded once as shared context. The result is inconsistent marketing output from a tool that could otherwise handle the full stack.

how marketingskills solves it

How it solves it#

50 marketing skill files across 8 disciplines

Covers SEO, CRO, copywriting, paid ads, lifecycle emails, growth, sales and GTM, and strategy. Skills are organized into a hierarchy, with the product-marketing skill as a shared foundation that every other skill reads first before executing its own workflow.

Agent Skills spec compatibility

Works with any agent that supports the Agent Skills spec, including Claude Code, Cursor, Windsurf, Codex, and Copilot. The CLI detects installed agents and routes skill files to the correct directory automatically: `.claude/skills/` for Claude Code, `.agents/skills/` for universal agents.

Shared product-marketing context across all skills

The product-marketing skill is a shared context file every other skill reads before executing. It holds your product's audience, positioning, and value propositions so each marketing task starts from the same baseline instead of requiring re-explanation every session.

Skills chain and cross-reference each other

Skills reference each other and build on shared context. The copywriting skill cross-references CRO and ab-testing; the SEO cluster chains seo-audit, schema, and ai-seo; customer-research feeds into copywriting, CRO, and competitor analysis. A single agent session can work coherently across multiple marketing disciplines.

Multiple install paths including CLI and git submodule

Install all 50 skills with one command: `npx skills add coreyhaines31/marketingskills`. Selective install via the `--skill` flag installs only the skills you need. A git submodule path is also available for version-controlled updates across projects.

Strengths and trade-offs#

Strengths

MIT license with no per-seat fees for the skill layerThe entire library is MIT licensed, so you can use it for commercial projects, modify skills for your stack, or fork the repo and maintain a private version. There is no SaaS tier, no feature gating, and no licensing cost for the skill files themselves.
No server or infrastructure to maintainUnlike marketing AI platforms that require account setup and a browser session, marketingskills installs as local markdown files. If your AI coding agent is running, the skills are available immediately with no additional service to maintain or pay for.
Consistent output through structured frameworksEach skill defines the workflow, frameworks, and related skills to consult for a task category. Rather than getting variable results from ad-hoc prompts, your agent applies a consistent marketing framework every time the relevant skill is triggered.

Trade-offs

-Requires an active AI coding agent subscriptionmarketingskills is a skill library, not a standalone product. It requires an active Claude Code, Cursor, Codex, or compatible agent subscription to function. Teams that do not already use an AI coding agent will need to set one up before the library is useful.
-Output quality depends on the underlying modelThe skill files provide structure and frameworks, but the quality of marketing output depends on the model powering your agent. A lower-tier model may not follow complex multi-step marketing workflows reliably. The repository carries 106 open issues, some covering edge cases where skill instructions produce inconsistent results across different models.

versus alternatives

marketingskills vs alternatives#

marketingskills vs Jasper AI

Both address the challenge of producing consistent marketing content with AI, but they serve different working environments. Jasper AI is a managed SaaS platform with a visual editor and proprietary AI models; marketingskills is a local skill library that runs on top of whatever AI coding agent you already have.

Feature	marketingskills	Jasper AI
License	MIT (free)	Proprietary SaaS
Self-hosting	No server required	No
Delivery	Skill files in your agent	Browser editor
Cost for the skill layer	Free	Paid subscription
Disciplines covered	SEO, CRO, copy, ads, analytics, growth (50 skills)	Copy-focused
Target user	Technical marketers, developers	Non-technical teams

marketingskills is the better choice if you are already running Claude Code, Cursor, or Codex and want marketing workflows inside your development environment. The 50 skills are free, MIT licensed, and chain together using your shared product-marketing context file.

Jasper AI is the better choice for non-technical marketing teams that need a visual interface, collaborative editing, and brand voice training. Teams that need approval flows or do not use a coding agent as a daily tool will find Jasper a stronger fit.

marketingskills vs Copy.ai

Copy.ai is a managed AI platform focused on go-to-market workflows and short-form copy. Like Jasper AI, it targets browser-based workflows rather than agent-native skill files.

Feature	marketingskills	Copy.ai
License	MIT (free)	Proprietary SaaS
Delivery	Agent skill files	Browser platform
Cost for the skill layer	Free	Paid subscription
SEO and analytics	Yes (seo-audit, ai-seo, analytics, schema)	Limited
Go-to-market workflows	Yes (launch, sales-enablement, prospecting)	Yes

For a technical founder using an AI coding agent, marketingskills covers more disciplines, runs at no extra licensing cost, and integrates directly with existing development tools. Copy.ai is worth considering if your team needs polished workflow UIs, collaboration features, or does not use an AI coding agent as a daily tool.

install · quick start

Quick start#

bash

Install the skill files by cloning the repository and copying skills into your agent's skill directory.
```bash

frequently asked

FAQ#

Is marketingskills free to use?

Yes. The library is MIT licensed and free for any purpose, including commercial projects. You pay for your own AI coding agent subscription (Claude Code, Codex, Cursor, etc.) but the skill files themselves carry no licensing cost.

Which AI agents does marketingskills support?

It works with any agent that supports the Agent Skills spec: Claude Code, OpenAI Codex, Cursor, Windsurf, and Copilot. The CLI install detects your installed agents and routes skills to the correct directory. If you run the install from inside an active Claude Code session, pass -a claude-code explicitly to target the .claude/skills/ directory.

How do I install only specific skills instead of all 50?

Use the --skill flag with the CLI: npx skills add coreyhaines31/marketingskills --skill cro copywriting. The --list flag shows all available skills with their descriptions before you install. You can also clone the repo and copy individual skill directories manually into your agent's skill folder.

Does marketingskills replace a paid marketing AI platform like Jasper AI?

Not directly. marketingskills is a library of agent skill files, not a standalone product with its own UI. It is best for teams already using an AI coding agent who want that agent to handle marketing tasks with consistent frameworks. Jasper AI and Copy.ai are managed SaaS platforms with visual editors better suited to non-technical marketing teams.

What is the product-marketing skill and why does every other skill reference it?

The product-marketing skill is a shared context document your agent reads before executing any other marketing task. It stores your product's audience, positioning, and value propositions so every skill starts from the same baseline. You fill it in once and all 49 other skills reference it automatically, preventing repeated re-explanation across sessions.
