Bora Oztunc Skills

A curated pack of about 70 Claude Code skills spanning copywriting, SEO, and CRO plus a large design and frontend craft library, most of it vendored from other authors under one roof.

The take

A designer's curated catalog of roughly 70 Claude Code skills. The marketing-useful slice is real, Ogilvy copywriting, an AI-slop remover, SEO audit, schema, programmatic SEO, content strategy, competitor pages, and page CRO, but it sits inside a much larger design and frontend library. Two honest catches: most of the pack is vendored from other authors (Emil Kowalski, impeccable, jakubkrehel, MengTo, HeyGen HyperFrames), not original work, and install is manual per-skill with no one-command installer or marketplace entry.

Great for

Founders and small GTM teams who want a few sharp, opinionated copy, SEO, and conversion skills (Ogilvy, stop-slop, seo-audit, page-cro, landing and pricing page IA) dropped into Claude Code, and who also do their own frontend and design work.

The catch

This is a design-first collection, not a sales or outbound engine; there is no cold-email, prospecting, CRM, or sequencing skill here. Much of it is other people's work re-hosted, so read the NOTICE files and go to the upstreams for the design and video skills you actually want.

Bottom line

One careful solo maintainer's shelf of good skills, alive and updated through August 2026, but small at 276 stars and Claude-Code-only. Take the handful of marketing skills you need, copy them in by hand, and read each SKILL.md first since skills run inside your agent.

At a glance
InstallManual per-skill: curl the SKILL.md into ~/.claude/skills/<name>/, or git clone the repo and symlink individual skills. No one-command installer, no plugin marketplace entry.
LicenseMIT for the repo's own skills (per README); GitHub detects Apache-2.0, and vendored skills carry their own licenses (Apache-2.0 and MIT). Check the per-skill NOTICE files.
LanguageMarkdown skill files, with JavaScript, CSS, and shader code in the examples
Maintained byBora Oztunc (solo; designer and builder at Nirmata Studio)
Harnesses supportedClaude Code only (SKILL.md plus slash command); no listed Cursor, Codex, or Gemini CLI install path
Watch out forDesign-heavy scope with no outbound or sales-automation skills, mostly vendored content, manual install, and a few skills that need API keys or paid dependencies
Feature checklist
Copywriting and advertising skillsOgilvy principles, general copywriting, copy editing
AI-slop removal (stop-slop)Strips predictable LLM phrasing and filler from prose
SEO skillsseo-audit, schema markup, programmatic SEO
Conversion and page IApage-cro, landing-page, pricing-page structure and formulas
Content strategy and sales enablementcontent-strategy, competitor-alternatives comparison pages, analytics-tracking setup
Design and frontend craft librarybetter-* domain rules, impeccable, apple-design, Tailwind v4, CSS and WebGL effects, largely vendored
Video generation (HyperFrames)Vendored HeyGen skills: author HTML compositions and render video
Image generationOne zine-poster skill only, and it needs a GEMINI_API_KEY
Cold outbound / prospecting / CRMNo cold-email, sequencing, lead-scoring, or CRM skill in the pack
One-command or marketplace installManual curl or clone-and-symlink per skill
Multi-harness supportClaude Code only as shipped
Enforced rulesEvery skill is guidance the model chooses to follow

What it does

  • Ships about 70 self-contained SKILL.md files you drop into ~/.claude/skills and invoke by slash command, each giving Claude Code deep domain knowledge on one topic
  • Covers a real marketing cluster: Ogilvy advertising principles, general copywriting, copy editing, an AI-slop remover (stop-slop), SEO audit, schema.org markup, programmatic SEO, content strategy, competitor comparison pages, page CRO, and analytics tracking setup
  • Includes landing-page, pricing-page, and other page-type skills that lay out single-intent IA, headline formulas, plan ceilings, and conversion structure
  • Carries a deep design and frontend library, the better-* interface domain rules, impeccable, apple-design, emil-design-eng, Tailwind v4, and dozens of exact CSS and WebGL effect recipes
  • Bundles the HeyGen HyperFrames video skills (author HTML compositions, render video, GSAP, Anime.js, Lottie, Three.js) and Vercel React performance guidance
  • States provenance for vendored skills in NOTICE files, naming each upstream author and license, so you can trace and verify what you install

What it can’t do

  • Run outbound for you; there is no cold-email, prospecting, sequencing, lead-scoring, or CRM skill in the pack, despite the outbound framing
  • Install in one command; every skill is copied in by hand via curl or a clone-and-symlink, with no skills.sh installer or Claude Code plugin marketplace entry
  • Work outside Claude Code as shipped; the install path targets ~/.claude/skills, with no documented Cursor, Codex, or Gemini CLI route
  • Claim most of the library as original; the design, video, and performance skills are vendored from Emil Kowalski, pbakaus/impeccable, jakubkrehel, MengTo, LiamGvchi, HeyGen, and brotzky, so upstream is often the better source
  • Enforce its own rules; every skill is guidance the model reads, so output quality tracks how well the agent follows the SKILL.md
  • Run every skill for free or offline; the zine-poster skill needs a GEMINI_API_KEY, shaders-cursor-ripples has a paid non-OSS dependency, and the HyperFrames skills drive a CLI that renders video

Pros & cons

Pros
  • A genuinely useful marketing slice, Ogilvy, copywriting, stop-slop, seo-audit, schema, programmatic SEO, content strategy, competitor pages, and page CRO, in one place
  • Curated with judgment, the MengTo subset kept 23 of 77 upstream skills and documents why the rest were rejected
  • Honest provenance, each vendored group names its upstream author and license in a NOTICE file instead of quietly copying
  • Skills are plain Markdown you can read end to end before installing, so there is no hidden runtime for the text-only ones
  • Actively maintained by one person, with additions landing steadily from March through August 2026
  • Permissive licensing overall (MIT and Apache-2.0), so commercial and client use is unencumbered
Cons
  • Design-first, not GTM; no cold outbound, prospecting, or sales-automation skills despite the outbound label
  • Most of the pack is vendored from other authors, so it is more a shelf than an original body of work, and upstreams may ship fresher versions
  • Manual per-skill install with no installer or marketplace entry adds friction versus one-command packs
  • Claude Code only as shipped, with no documented path for Cursor, Codex, or Gemini CLI
  • Small and niche at 276 stars and one maintainer, so bus factor and support are thin
  • License is mixed and slightly muddled: README says MIT while GitHub detects Apache-2.0, and vendored skills carry their own terms, so you must check per skill
