What it does

GitHub is an agent skill from kostja94/marketing-skills. When the user wants to use GitHub for SEO, parasite SEO, GEO, open source marketing, README optimization, or curated Awesome lists. Also use when the user mentions "GitHub," "GitHub SEO," "GitHub parasite SEO," "GitHub GEO," "awesome list," "GitHub README," "profile README," "pinned repositories," "Trending," "Explore," "repository name," "About section," "GitHub description," "GitHub topics," "Website field," "GitHub Pages," "github.io," "user site," "project site," "GitHub gist," "curated list," or "navigation…

Its SKILL.md is about 4.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Technical documentation, Product strategy and AI search optimization. It works with GitHub. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.

When your agent uses it

  • Wants to use GitHub for SEO
  • Open source marketing
  • README optimization
  • Curated Awesome lists

Example prompts

  • “GitHub,”
  • “GitHub SEO,”
  • “GitHub parasite SEO,”
  • “/github”

Requirements

  • Node.js

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Title + answer-first tagline (+ slim badge row).
  2. ### What I do — identity, proof link(s), without repeating the same URLs again later.
  3. ### Open source — bold repo links + pitches + optional one code fence.
  4. ### Find me — single line of deduped links (site · bio · cases · social · email).
  5. ### Activity (optional) — small github-readme-stats + star-history; alt text on .

What it can do on your machine

Read from SKILL.md and the folder at commit 8dd89c5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • username.github.io

    Also links to:

    • docs.github.com
    • github.com
    • star-history.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

GitHub loads about 4.5k tokens when it runs. Until then it costs about 165 tokens; SKILL.md has 1,918 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~165
When it runs · the whole SKILL.md, loaded when a task matches
~4.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

FactorEffect
Domain authorityHigh DA; repos, gists, Pages rank well
Fast indexingSearch engines crawl GitHub frequently
AI citationChatGPT, Perplexity cite GitHub for technical queries; Tier 2 in GEO framework
Technical expertiseStrong expertise signals; structured docs become AI reference material
Cross-platformShare across Dev.to, Stack Overflow, forums; amplifies visibility

Use Cases

Use caseFormatPurpose
Parasite SEORepos, README, Pages, gistsLeverage GitHub authority for rankings and backlinks
GEODocumentation, tutorials, curated listsAI tools cite GitHub for technical answers
Curated / navigation listsAwesome-style reposTopic-specific resource directories; backlinks, discovery

Surfaces: profile vs repository

SurfaceWhat it isOptimization focus
Profile READMEPublic repo with the same name as the username; root README.md renders on the profilePersonal brand, flagship links, social proof
PinnedUp to 6 repos or gists on the profileShowcase top projects; align with entity signals (entity-seo)
Per-repo READMERoot README.md on each repo’s Code tabProduct 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.

Profile README (username/username)

Not the same as a product repo README. Optimize for identity + navigation in ~15–40 lines of rendered content unless the user explicitly wants a long-form CV. Official setup: Managing your profile README.

PrincipleDoAvoid
LengthShort, scannable sections; omit ToC unless the file is genuinely longApplying “500–1,500 words typical for product repos” here
Headings### blocks (e.g. What I do · Open source · Find me) for fast eyeballingMany nested ## + long narrative without breaks
LinksEach primary URL once in a Find me / Connect line (or badges or a slim table—not all three repeating the same destinations)Duplicate site/LinkedIn/email in badges, tables, and prose
Repos blockBold repo name + ≤2 short lines + at most one copy-paste command (e.g. npx skills add …) — same scan pattern popular profiles use for “flagship OSS” without cloning the repo’s full READMEFull feature matrices, changelog, or install docs pasted into the profile file
LayoutOptional centered header (<div align="center">) for name + tagline + badges only; body stays left-aligned markdown for readabilityCenter-wrapping the entire README
Optional widgetsCompact Shields (flat style); optional github-readme-stats / star-history — third-party, treat as conversion/social proof, not core SEOWall of for-the-badge badges when the same CTAs are repeated in text

Minimal outline (typical profile):

  1. Title + answer-first tagline (+ slim badge row).
  2. ### What I do — identity, proof link(s), without repeating the same URLs again later.
  3. ### Open source — bold repo links + pitches + optional one code fence.
  4. ### Find me — single line of deduped links (site · bio · cases · social · email).
  5. ### Activity (optional) — small github-readme-stats + star-history; alt text on <img>.

Reference pattern (high-signal, low-noise): scan-first profiles such as alchaincyf — short ### blocks, bold product/repo names, one “find me” cluster.

Entity hub pattern: When the person has a canonical site, lead with it in the opening line and mirror the same URL in Pinned / profile About (if used) so site ↔ GitHub OSS stay aligned for entity-seo.

Profile README checklist (short)
  • H1 + one answer-first tagline (keywords: role, stack, domain)
  • Canonical outbound links (site, social, email) deduplicated
  • Pinned repos (≤6) match the story told in the README
  • Optional: Activity section — group stats / star-history under one heading instead of scattering widgets
  • Last updated footnote for freshness (GEO signal)

Repository home: layout map

AreaTypical contentsSEO / ops note
Main columnFile list; rendered root README belowFirst screen and H2/H3 carry most narrative
About sidebarDescription, Website, Topics, releases shortcut, license, languagesKeep Description and README first paragraph consistent; Website should match the primary outbound CTA
Other tabsIssues, PRs, Actions, etc.Engagement and freshness signals

Website field: Maintained via repo Settings / About edit; prefer one canonical docs or product URL aligned with README links.

In-site discovery (high level)

Repository Name, About & README (SEO/GEO Priority)

Ranking weight (GitHub + Google): Repository name & About ≈ highest; Topics ≈ high; README ≈ high.

Underutilized but highly effective for discoverability and GEO.

README Structure & Components

Targets repository (project) READMEs unless noted. Profile README overrides: shorter, fewer sections—see Profile README (username/username) above.

SectionPurposeSEO/GEO
Title + taglineH1 + 1–2 sentence summary; keywords in first paragraphCritical; first 100 words weighted
Table of contentsLinks to H2/H3; for long repo READMEs (often >500 words). Usually skip on profile READMENavigation; crawlability
Installation / Quick startPrerequisites; exact commands; copy-paste readyUse-case clarity
Usage examplesCode blocks; common scenariosCitable; extractable
Screenshots / GIFsDemo, output; alt text requiredEngagement; accessibility
BadgesBuild, version, licenseTrust signals
ContributingLink to CONTRIBUTING.mdCommunity signal
LicenseLink to LICENSECompleteness

Word count: No hard limit; 500–1,500 words typical for product / library repos. Lead with value; expand later. Profile README: prefer dense brevity—long-form belongs on the canonical site or in pinned repos’ own READMEs.

README GEO / AI Citation
PracticeGuideline
Answer-firstDirect answer in first 1–2 sentences (40–60 words); profile README may compress to one punchy tagline under H1 if outbound links carry the rest
Short paragraphs2–3 sentences max; extractable clarity
Question-style headingsH2/H3 as questions where relevant (repository READMEs); on profile README, optional — clarity of sections matters more than question phrasing
Data inclusionStats, numbers; cited content ~40% more likely to include data
FreshnessUpdate regularly; ~76% of cited content updated within 30 days

Entity signals: Clear project name, author, maintainer; consistent identity. See entity-seo.

README Checklist — repository (default)
  • Project title with keywords
  • Concise description in first paragraph
  • H2/H3 structure; alt text for images
  • Installation + usage examples
  • Screenshots or demo
  • Badges; Contributing; License
  • Internal links to related docs/repos
  • 6–20 topics on repo

(For profile username/username, use the shorter Profile README checklist under Surfaces—not every row above applies.)

Parasite SEO on GitHub

Key Surfaces
SurfaceUse
READMELanding page for repo; keyword-optimized summary, headings, links
GitHub PagesStatic site; blog, FAQ, docs; additional ranking opportunities
GistsMicro-content; long-tail keywords; link to repos or external resources
WikiKeyword-rich documentation
IssuesQ&A, discussions; indexable
GitHub Pages vs README
SurfaceRole
READMEFirst impression; Stars/forks; short pitch and deep links
PagesMulti-page static site: long docs, blog, changelog

Default URL patterns: A user or organization site often uses a username.github.io repository and serves at https://username.github.io. A project site is published from a given repo and typically appears at https://username.github.io/repository/ (path may vary with settings). See About GitHub Pages.

Limits: Build size, bandwidth, and build-frequency caps change over time—cite GitHub Pages limits when users need numbers, not hard-coded figures from this skill.

Repository archetypes

ArchetypeIntentFirst-screen emphasis
Product / libraryInstallable software, SDK, CLI, serviceInstall, quickstart, proof (CI, license), support path
Curated / resourceAwesome-style lists, indexesScope, curation bar, contribution rules
Personal profile hubPublic username/username README on the profileIdentity + canonical links + pinned flagship repos; no duplication of full product READMEs

Match metrics to type: curated lists optimize for trust and backlinks; product repos optimize for adoption and issue quality.

Curated / Navigation Lists (Awesome-Style)

Awesome lists = Curated, topic-specific resource lists on GitHub. Function like navigation directories; high traffic, backlinks, discovery. sindresorhus/awesome (441K+ stars) is the master list; 6,500+ curated lists exist across topics.

Common Mistakes

MistakeAvoid
Ignoring engagementNot responding to issues/PRs reduces trust
Irregular updatesOutdated repos signal inactivity
Incomplete docsLack of clear descriptions frustrates users
Generic titlesMissing keywords reduces discoverability
Thin awesome listsLow-quality or uncurated items hurt credibility
Profile README = product READMEPasting install/Contributing/screenshot-heavy templates on username/username — use the profile checklist
Link sprawl on profileSame homepage/social/email repeated in badges, tables, and long copy — consolidate
