Its SKILL.md is about 670 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 SEO. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 4eb71d9. 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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
schema.orgFrom 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.
SEO loads about 673 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 143 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.

SEO fits situations like: tasks that involve Technical SEO.
Run `npx skills add affaan-m/ECC --skill seo -a claude-code`. Or copy the skill folder (docs/ja-JP/skills/seo in affaan-m/ECC) into .claude/skills/seo in your project. Claude Code loads it when a task matches its description.
Run `npx skills add affaan-m/ECC --skill seo -a codex`. Or copy the skill folder (docs/ja-JP/skills/seo in affaan-m/ECC) into .agents/skills/seo 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 affaan-m/ECC --skill seo -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/seo, .gemini/skills/seo, .github/skills/seo and .opencode/skills/seo in your project.
SKILL.md names no scripts, command-line tools or credentials: SEO is instructions for the agent only.
SKILL.md names 1 domain. In commands or code: schema.org; the agent is likely to contact it when it follows the instructions. 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.
SEO is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 673 tokens (SKILL.md is roughly 2.7k 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 SEO: Hreflang and International SEO (AgriciDaniel/claude-seo, 19k stars), Google SEO APIs (AgriciDaniel/claude-seo, 19k stars), GEO-First SEO Audit Tool (zubair-trabzada/geo-seo-claude, 11k stars) and SEO Optimizer (ailabs-393/ai-labs-claude-skills, 455 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
