Marketing Skills is an open-source library of reusable workflows that helps AI coding agents perform marketing and SEO tasks. It serves people working on search optimization, content, advertising, launches, analytics, and related marketing activities, and its catalogue entries are the individual skills agents can install.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00165 | $0.04298 |
| Opus 5.5 | $0.00066 | $0.01719 |
| Sonnet 5.5 | $0.00033 | $0.00860 |
| Haiku 4.5 | $0.00016 | $0.00430 |
Grade A, and why
github scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 327 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Platforms: GitHub
Guides GitHub for parasite SEO, GEO (AI citation), and curated list creation. GitHub is a Tier 2 Technical Authority platform—high domain authority, fast indexing, very high AI citation probability. Use for repos, README, GitHub Pages, gists, and Awesome-style navigation lists.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Why GitHub for SEO
| Factor | Effect |
|---|---|
| Domain authority | High DA; repos, gists, Pages rank well |
| Fast indexing | Search engines crawl GitHub frequently |
| AI citation | ChatGPT, Perplexity cite GitHub for technical queries; Tier 2 in GEO framework |
| Technical expertise | Strong expertise signals; structured docs become AI reference material |
| Cross-platform | Share across Dev.to, Stack Overflow, forums; amplifies visibility |
Use Cases
| Use case | Format | Purpose |
|---|---|---|
| Parasite SEO | Repos, README, Pages, gists | Leverage GitHub authority for rankings and backlinks |
| GEO | Documentation, tutorials, curated lists | AI tools cite GitHub for technical answers |
| Curated / navigation lists | Awesome-style repos | Topic-specific resource directories; backlinks, discovery |
Surfaces: profile vs repository
| Surface | What it is | Optimization focus |
|---|---|---|
| Profile README | Public repo with the same name as the username; root README.md renders on the profile |
Personal brand, flagship links, social proof |
| Pinned | Up to 6 repos or gists on the profile | Showcase top projects; align with entity signals (entity-seo) |
| Per-repo README | Root README.md on each repo’s Code tab |
Product landing; install, proof, CTAs |
Changing a normal repo README does not change the profile banner unless that content is the profile README repo or linked from it.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
