Full website SEO audit with parallel subagent delegation. An agent skill from andrew-yangy/gru-ai.

  • Works in 6 steps: Fetch homepage — use… → Detect business type — analyze homepage… → Crawl site — follow internal links up to… → …
  • User says audit
  • SKILL.md covers Process, Crawl Configuration, Output Files and Scoring Weights, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

SEO Audit is an agent skill from andrew-yangy/gru-ai. Full website SEO audit with parallel subagent delegation. Crawls up to 500 pages, detects business type, delegates to 6 specialists, generates health score. Use when user says "audit", "full SEO check", "analyze my site", or "website health check".

Its SKILL.md is about 730 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 SEO audit, On-page SEO and Technical SEO. The repository describes itself as: Autonomous AI agent team for one-man companies. Context engineering + harness engineering drive a pipeline that brainstorms, builds, reviews, and ships. The licence is MIT.

When your agent uses it

  • User says audit
  • Analyze my site
  • Website health check

Example prompts

  • “full SEO check”
  • “analyze my site”
  • “website health check”
  • “/seo-audit”

Workflow steps

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

  1. Fetch homepage — use scripts/fetch_page.py to retrieve HTML
  2. Detect business type — analyze homepage signals per seo orchestrator
  3. Crawl site — follow internal links up to 500 pages, respect robots.txt
  4. Delegate to subagents (if available, otherwise run inline sequentially)
  5. Score — aggregate into SEO Health Score (0-100)
  6. Report — generate prioritized action plan

What it can do on your machine

Read from SKILL.md and the folder at commit 8fba479. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

SEO Audit loads about 731 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~731

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.
