The largest single marketing-focused skill bundle in the community — 36+ Claude Code / Codex / Cursor / Windsurf skills covering conversion optimization, copywriting, SEO, paid ads, analytics, retention, growth, sales, and strategy. Uses a foundation-skill pattern: product-marketing-context captures your product/audience/positioning once, and every other skill references it first. Install via npx skills add or Claude Code’s plugin marketplace. Many of these skills appear in the Claude plugin-skill marketplaces I use directly.

Key Takeaways

  • 36+ skills, one foundation. product-marketing-context is read by every other skill before any marketing work begins. Classic good-architecture move — product/ICP/positioning is captured once, not repeated across prompts.
  • Multi-agent compatibility. Works with Claude Code, OpenAI Codex, Cursor, Windsurf, and anything compliant with the Agent Skills spec (agentskills.io). Not Claude-locked.
  • Six install methods. npx skills add (recommended), Claude Code /plugin install, clone + copy, git submodule, fork, npx skillkit install (multi-agent). Sensible matrix for different team setups.
  • Installs to .agents/skills/. v2.0 moved from .claude/ to .agents/ (symlinked to .claude/skills/ for Claude Code compatibility). Aligned with the emerging Agent Skills open standard per Building Agents with Skills.
  • Cross-references matter. Skills form a dependency graph: copywriting ↔ page-cro ↔ ab-test-setup; revops ↔ sales-enablement ↔ cold-email; seo-audit ↔ schema-markup ↔ ai-seo. Explicit “Related Skills” sections in each.
  • Ecosystem is production. Author also runs Conversion Factory (agency), Swipe Files (newsletter), Magister (autonomous-CMO agent using these skills). The skills represent real client-facing methodology, not weekend projects.
  • 21.8K stars, Apr 2026 active. One of the largest community skill bundles — comparable in star count to core Anthropic repos. High-confidence quality signal.

Architecture — the foundation-skill pattern

All 35 non-foundation skills start by reading product-marketing-context:

         product-marketing-context  ← read first by every skill
                    │
  ┌────────────┬────┴────┬──────────┬──────────┬──────────┬─────────┐
  SEO/Content  CRO      Copy/Email  Paid/Test  Retention  Sales/GTM  Strategy

This is the same progressive-disclosure philosophy as Agent Skills Overview — metadata loads cheap; full body loads when triggered; references to other skills/files load on demand. product-marketing-context is the one Level-1 skill that’s effectively always in context for marketing work.

Benefit: you describe your product once. Every downstream skill (copywriting, CRO, paid ads, launch strategy) already has your positioning, target customer, and key benefits. No re-prompting.

All methods land in .agents/skills/ and (for Claude Code) symlink into .claude/skills/.

Usage examples

Natural-language invocation (agent picks the right skill from description match):

"Help me optimize this landing page for conversions"   → page-cro
"Write homepage copy for my SaaS"                      → copywriting
"Set up GA4 tracking for signups"                      → analytics-tracking
"Create a 5-email welcome sequence"                    → email-sequence
"Plan a launch for our new feature"                    → launch-strategy
"Audit our SEO for AI search"                          → ai-seo

Direct invocation:

/page-cro
/email-sequence
/seo-audit
/product-marketing-context    ← run this first for any new project

Implementation

  • Tool/Service: marketingskills (Corey Haines)
  • Setup:
    1. npx skills add coreyhaines31/marketingskills in your project
    2. Run /product-marketing-context once to capture product/audience/positioning
    3. Use any of the 35 downstream skills — they’ll pick up that context automatically
  • Cost: Free (MIT license). No hosted service required — skills are markdown files.
  • Integration notes:
    • Works alongside Claude’s own skills (Skills Ecosystem). No conflict — these are additive.
    • product-marketing-context is the canonical place to store your product/ICP/positioning in a Claude Code project. Keep it in version control.
    • Many of these skills are also available in the broader Claude plugin-skill marketplaces (see Plugins and Marketplaces) — installing from here gives you the full curated set instead of picking individually.
    • For AI-first SEO specifically, the ai-seo skill complements SEO & Content topic and the broader SEO Content topic.

Where it fits in the wiki

  • Marketing stack: composes with AI Marketing topic for end-to-end campaign workflows
  • Claude skills landscape: an exemplary instance of the Agent Skills pattern — Partner Skills category per Anthropic’s taxonomy
  • Cowork alignment: Cowork Plugins has its own marketing plugin; these Corey Haines skills are richer/more specific — the two are complementary (Cowork plugin is the “turn marketing on” installer; this bundle is the deep methodology)
  • SEO overlap: seo-audit, ai-seo, programmatic-seo, site-architecture, schema-markup, competitor-alternatives overlap with seo-content topic. The seo-content topic is WEO-specific; these skills are the generalist equivalent.
  • Agent Skills spec: follows the emerging open standard referenced by Building Agents with Skills

Open Questions

  • Skill-quality uniformity. 36 skills by one author is a lot to maintain. Which are battle-tested from Conversion Factory client work vs exploratory? Not explicitly labeled in the README.
  • Magister integration. Magister is described as “an autonomous AI agent that uses these skills to be your CMO.” Is Magister proprietary or open, and how does it orchestrate these skills sequentially for ongoing campaigns?
  • Versioning strategy. v1.0 → v2.0 moved from .claude/ to .agents/. What’s the breaking-change cadence? Any semver commitments?
  • Overlap with Anthropic’s bundled skills. Anthropic ships design-focused skills (frontend-design, taste-skill); Corey ships marketing-focused skills. Is there a gentlemen’s agreement on non-overlap, or will Anthropic eventually ship official copywriting/page-cro skills too?
  • Measurement. Do any of the skills report back on what worked? Or are they pure authoring skills with no feedback loop?

Try It

  1. Install just product-marketing-context and one other skill first — maybe page-cro or copywriting. npx skills add coreyhaines31/marketingskills --skill product-marketing-context page-cro. Teaches the foundation-skill pattern before committing to 36.
  2. Run /product-marketing-context on a real project. Fill in your product, audience, and positioning. Commit the file. Every subsequent marketing skill run will be materially better.
  3. A/B one marketing task against its skill version. Write a landing-page copy without the copywriting skill; rewrite with it. The skill imposes structure and voice; measure whether output quality shifts.
  4. Audit the skill graph. Open the README’s dependency map. Identify which 3–5 skills form your “core loop” for your business. Install those + product-marketing-context only. Most teams don’t need all 36.
  5. Compare with Cowork’s Marketing plugin. If you’re on Claude Cowork, install both. Use them on the same task. Which feels more specific to your actual workflow?
  6. Subscribe to Swipe Files (https://swipefiles.com) and/or browse Conversion Factory (https://conversionfactory.co) — this is the editorial context the skills distill. Useful to understand the methodology under the prompts.
