Blog SEO Check is an agent skill from Infrasity-Labs/dev-gtm-claude-skills. Post-writing SEO validation with pass/fail checklist covering title tag length and keyword placement, meta description quality, heading hierarchy and keyword density, internal/external link audit with anchor text analysis, canonical URL verification, Open Graph meta tags (og:title, og:description, og:image), Twitter Card validation, URL structure optimization, and image alt text presence. Produces prioritized fix list with specific recommendations. Use when user says "seo check", "check seo", "validate seo"…
Its SKILL.md is about 2.3k 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 On-page SEO. It works with X (Twitter). The repository describes itself as: Open-source Claude skills for GEO, AI discoverability, and developer GTM workflows. Built for developer-focused companies that want their documentation to be found, parsed, and… The licence is MIT.
12 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 02cfefb. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Blog SEO Check loads about 2.3k tokens when it runs. Until then it costs about 162 tokens; SKILL.md has 990 words of instructions outside code blocks.
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.
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.

Run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill blog-seo-check -a claude-code`. Or copy the skill folder (.claude/skills/blog-seo-check in Infrasity-Labs/dev-gtm-claude-skills) into .claude/skills/blog-seo-check in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill blog-seo-check -a codex`. Or copy the skill folder (.claude/skills/blog-seo-check in Infrasity-Labs/dev-gtm-claude-skills) into .agents/skills/blog-seo-check in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Infrasity-Labs/dev-gtm-claude-skills --skill blog-seo-check -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/blog-seo-check, .gemini/skills/blog-seo-check, .github/skills/blog-seo-check and .opencode/skills/blog-seo-check in your project.
Going by SKILL.md and its folder, Blog SEO Check needs the command-line tools its instructions call (python3). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Blog SEO Check is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Blog SEO Check: SEO Page (AgriciDaniel/codex-seo, 799 stars), Meta Tags Optimizer (ViryaZheng/recomby-geo, 458 stars), SEO Fundamentals (DanielPodolsky/ownyourcode, 290 stars) and Browser4 SEO (platonai/Browser4, 1.2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
