For extending an agent’s work into research, messaging and conversion. 50 specialized marketing instructions (CRO, SEO, ads, copywriting, analytics) that any code agent can use for free. MIT license, no API key, one command to install.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. 50 specialized marketing instructions (CRO, SEO, ads, copywriting, analytics) that any code agent can use for free. MIT license, no API key, one command to install.
Its limit. Everything in English: instructions, templates, and documentation. Getting output in another language requires asking the agent explicitly.
These are text files that teach marketing to your code agent (Claude Code, Cursor, Codex). Tell it to "optimize this landing page" and instead of winging it, it applies a real CRO framework.
Compatibility and setupRequirements and agent differences
Compatibility. Claude Code, Cursor, OpenAI Codex, Windsurf, and any agent supporting the Agent Skills spec. Node.js required for installation via npx.
Real cost and licenseResource, agent and extra costs
Cost. Free. MIT license. No API key, no subscription, no usage limits. Partners (Converly, Ploy) fund development but do not influence core skill recommendations according to the project documentation.
Example and alternativeWhen it helps and what else to use
Example. Install all 50 skills with npx skills add coreyhaines31/marketingskills, fill in the product-marketing.md document with your product context, then ask the agent to audit a landing page for conversion.
Alternative. Write your own Markdown skills tailored to your workflow, or use system prompts directly in the agent without an external library.
Sources and reviewWhat is documented and what was tested
Review. Article based on official repository documentation (README, website) as of September 2026. No hands-on testing by the Marketing Ultra team.

HeliosGen
Resource
Builds image and video workflows with nodes and documents an optional Codex CLI integration for GPT Image 2.
Why it belongs here. Builds image and video workflows with nodes and documents an optional Codex CLI integration for GPT Image 2.
Its limit. The application is local, but generation depends on external services. Project maturity and available builds limit production use.
Connect text, reference images and a model like parts of a circuit. Save the route and use it again.
Compatibility and setupRequirements and agent differences
Details. The documentation offers a macOS Apple Silicon download. Windows and Linux require building from source. The optional Codex route has separate requirements.
Real cost and licenseResource, agent and extra costs
Details. The MIT-licensed application is free. Generation uses kie.ai credits or the configured provider account. There is no universal price per image.
Example and alternativeWhen it helps and what else to use
Details. Useful for preparing creative variations and repeating a sequence. A direct generation interface is simpler when you only need one image.
Sources and reviewWhat is documented and what was tested
Details. Official sources and the published review checked on 21 September 2026. Codex integration is documented, not presented as independent testing.

Resource
For extending an agent’s work into research, messaging and conversion. The only open source resource that audits up to 12 advertising platforms with 33 skills, findings classified by confidence level, and investment-weighted scoring — all from Claude Code.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. The only open source resource that audits up to 12 advertising platforms with 33 skills, findings classified by confidence level, and investment-weighted scoring — all from Claude Code.
Its limit. Requires account exports or real API access to function. Installation alone analyzes nothing, and account-level operations require connectors and manual per-platform authorization.
A free skill that reviews the health of your ad accounts (Google Ads, Meta, TikTok and more) from Claude Code. It tells you what is wrong, how confident it is, and what to prioritize. It does not touch anything without your permission.
Compatibility and setupRequirements and agent differences
Compatibility. Claude Code is the canonical environment. Codex, Gemini CLI, Cursor, Windsurf and Goose can consume the skill files where their runtime allows, but with no published functional proof outside Claude Code.
Real cost and licenseResource, agent and extra costs
Cost. Free and MIT-licensed. No subscription, no external server, no per-account fee. Indirect costs are the Claude Code subscription and tokens consumed during the audit.
Example and alternativeWhen it helps and what else to use
Example. Install with /plugin marketplace add AgriciDaniel/claude-ads, configure with /ads setup and run /ads audit google for a Google Ads audit with health score and prioritized findings.
Alternative. Manual PPC audits platform by platform, or paid SaaS tools like Optmyzr, Adalysis or Opteo (typically focused on one or two platforms).
Sources and reviewWhat is documented and what was tested
Review. Reviewed at Marketing Ultra on September 22, 2026 based on the README, official website and repository documentation. No functional test was run on live accounts.

Claude SEO
Resource
For extending an agent’s work into research, messaging and conversion. Full SEO kit for Claude Code with 18 agents that prioritize findings and add falsifiability to every recommendation. MIT, no cost per domain.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. Full SEO kit for Claude Code with 18 agents that prioritize findings and add falsifiability to every recommendation. MIT, no cost per domain.
Its limit. The SKILL.md injects a promotional footer for the author's community into generated reports. The 0–100 score is an internal heuristic, not a Google signal.
Give it a URL and Claude Code returns an SEO report with issues sorted by priority and a concrete way to check whether each fix worked.
Compatibility and setupRequirements and agent differences
Compatibility. Claude Code on macOS, Linux, and Windows. Requires Python 3.10+. Codex SEO is a separate port outside this package.
Real cost and licenseResource, agent and extra costs
Cost. The skill is free (MIT). You need an active Claude Code subscription. Since v2.3.1, five agents run on Opus, which increases consumption. Optional extensions (DataForSEO, Ahrefs) require separate paid accounts.
Example and alternativeWhen it helps and what else to use
Example. /seo audit https://your-site.com for a full audit with up to 18 agents. /seo page for a single URL. /seo schema for markup.
Alternative. Screaming Frog for deep crawling, Ahrefs Site Audit for link analysis with its own index, Semrush Site Audit for competitive visibility.
Sources and reviewWhat is documented and what was tested
Review. Data from the GitHub repository, official website, and public sources (Reddit, YouTube). The tool was not run for this review. September 2026.

Marketing Skills de Alireza Rezvani
Resource
For extending an agent’s work into research, messaging and conversion. Organized suite of marketing skills with shared brand context and organization across 8 pods (content, SEO and AEO, local SEO, CRO, channels, growth, market intelligence, and sales), compatible with 13 coding agents.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. Organized suite of marketing skills with shared brand context and organization across 8 pods (content, SEO and AEO, local SEO, CRO, channels, growth, market intelligence, and sales), compatible with 13 coding agents.
Its limit. No evidence of real marketing use. The 26,000+ stars belong to the full multidisciplinary repository, not the marketing package. The main skill is a router that does not execute work on its own.
A set of instructions that teach your coding assistant to handle marketing tasks (emails, CRO, SEO, analytics) without you having to explain everything from scratch every time. Free, open source, for Claude Code and 12 other agents.
Compatibility and setupRequirements and agent differences
Compatibility. The README declares support for 13 platforms: Claude Code, OpenAI Codex, Gemini CLI, Cursor, Aider, Windsurf, Kilo Code, OpenCode, Augment, Antigravity, Hermes Agent, Mistral Vibe, and OpenClaw. Compatibility documented in README and frontmatter, not verified with execution tests. On Windows, requires cloning with symlinks enabled (Developer Mode).
Real cost and licenseResource, agent and extra costs
Cost. Open source under MIT license. No licensing fee or subscription. The only cost is the coding agent you run it on (Claude Code, Codex, Cursor, etc.) and the time to configure the brand context.
Example and alternativeWhen it helps and what else to use
Example. In Claude Code: /plugin marketplace add alirezarezvani/claude-skills and then /plugin install marketing-skills@claude-code-skills. The router loads the index and distributes work to the specialists in each pod.
Alternative. The Corey Haines package covers similar ground with less complexity. Rezvani bets on depth and scale (more specialists, more scripts, more pods); Haines on a more direct and lightweight approach.
Sources and reviewWhat is documented and what was tested
Review basis. Reviewed from the repository README, the marketing-skills index SKILL.md, and the verified structure of the marketing-skill directory on GitHub. No hands-on execution test. Last repository activity: August 2026. Full repo stars: 26,213 as of review date (September 2026).

OpenClaudia Skills
Resource
For extending an agent’s work into research, messaging and conversion. It bundles more than 70 marketing skills into an open package and provides a specific route for querying GA4 reports and conclusions from a coding agent.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. It bundles more than 70 marketing skills into an open package and provides a specific route for querying GA4 reports and conclusions from a coding agent.
Its limit. The skill does not include automatic Analytics access: it requires Google OAuth, property access, and human verification of reports; nor is there a documented independent execution.
In plain English: it lets you ask an assistant to query GA4 from the terminal and organize the data, provided you first connect your Google account correctly.
Compatibility and setupRequirements and agent differences
Compatibility. Claude Code is the main documented requirement. Codex supports a specific path for skills; Grok CLI, Gemini CLI, Cursor, and Windsurf can use the content as instructions or rules, without a guarantee of identical operation.
Real cost and licenseResource, agent and extra costs
Cost. The package is free and MIT-licensed. Credentials, permissions, and any external services needed for other skills fall outside that free offering.
Example and alternativeWhen it helps and what else to use
Example. Install google-analytics, configure OAuth, and request a basic report from an authorized property, then compare its figures with GA4.
Alternative. Keeping analysis in the original SaaS dashboards avoids adding another layer of instructions and credentials, although it requires switching interfaces for each task.
Sources and reviewWhat is documented and what was tested
Review. Profile reviewed on September 25, 2026, based on the OpenClaudia Skills repository and main documentation.

Claude Blog
Resource
For extending an agent’s work into research, messaging and conversion. It deserves a place in the roundup because it brings the brief, research, writing, validation and technical preparation of articles for several CMSs into one suite.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. It deserves a place in the roundup because it brings the brief, research, writing, validation and technical preparation of articles for several CMSs into one suite.
Its limit. Its editorial score is an internal heuristic, and its documented compatibility requires Claude Code CLI and Python 3.11+; it does not guarantee quality, rankings or citations by AI assistants.
In plain English: it is an automated editorial team inside the terminal that assigns each article to specialised tasks and checks the deliverables before showing them to you.
Compatibility and setupRequirements and agent differences
Compatibility. Documented for Claude Code CLI on macOS, Linux and Windows, with Python 3.11 or later. The dossier does not verify Codex or other agents.
Real cost and licenseResource, agent and extra costs
Cost. The repository is free and licensed under MIT. Optional APIs and services may create external costs that are not quantified in the provided documentation.
Example and alternativeWhen it helps and what else to use
Example. It can coordinate an article from strategy and briefing through to Markdown, HTML, PDF, screenshots and a review report.
Alternative. Jasper, Copy.ai and Writesonic are the stated alternatives for anyone who prefers a hosted platform.
Sources and reviewWhat is documented and what was tested
Review. The conclusion is based on the public documentation for version 2.2.0. The installation and test described were not run for this review.

GEO SEO Claude
Resource
For extending an agent’s work into research, messaging and conversion. It brings citability checks, crawler access, schema, content and GEO reports together in a single Claude Code skill.
Why it belongs here. For extending an agent’s work into research, messaging and conversion. It brings citability checks, crawler access, schema, content and GEO reports together in a single Claude Code skill.
Its limit. Its scores describe readiness through heuristics; they do not prove real mentions or citations in AI assistants.
In plain English: it checks whether your website is organised so AI search engines can crawl and understand it, but it does not confirm that they are showing it.
Compatibility and setupRequirements and agent differences
Compatibility. The documentation requires Claude Code CLI, Git and Python 3.8 or later. Windows requires Git Bash; there is no verified compatibility with Codex, Cursor or other agents.
Real cost and licenseResource, agent and extra costs
Cost. The repository publishes the code under an MIT licence. Claude Code, external services and the commercial community linked by the author have independent terms; no single price in euros has been verified.
Example and alternativeWhen it helps and what else to use
Example. It can review robots.txt, structured data and content blocks before preparing a GEO report for a client.
Alternative. The dossier does not establish a direct replacement. Claude SEO is a related tool that overlaps with general technical SEO auditing.
Sources and reviewWhat is documented and what was tested
Review. This listing was reviewed on 27 September 2026 using the repository, its README and verified licence information. The installation was not run.
