seo-firecrawl

seo-firecrawl is a skill for Claude Code from Infrasity-Labs/dev-gtm-claude-skills. It costs 61 tokens per session (1,982 once invoked), scanned A, a copy of seo-firecrawl, MIT.

A website-crawling and mapping guide built around Firecrawl, a service that reads web pages and follows their links. It covers full-site crawls, page discovery, single-page scraping, and searches within crawled content.

In plain words
What is it for?
Finding all pages, mapping site structure, scraping rendered pages, searching a crawled website, and checking links or metadata across a site.
Why use it?
It helps collect information from JavaScript-heavy sites and understand a site's page structure. It also makes broken-link and site-wide analysis more systematic.

Token cost

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.

Security

Grade A, and why

seo-firecrawl 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 13d 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.

Origin

This is a copy

97% identical to seo-firecrawl — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Firecrawl Extension for Claude SEO

This skill requires the Firecrawl extension to be installed:

./extensions/firecrawl/install.sh

Check availability: Before using any Firecrawl tool, verify the MCP server is connected by checking if firecrawl_scrape or any Firecrawl tool is available. If tools are not available, inform the user the extension is not installed and provide install instructions.

Quick Reference

Command Purpose
/seo firecrawl crawl <url> Full-site crawl with content extraction
/seo firecrawl map <url> Discover site structure (URLs only, fast)
/seo firecrawl scrape <url> Single-page scrape with JS rendering
/seo firecrawl search <query> <url> Search within a crawled site

Commands

crawl -- Full-Site Crawl

Crawl an entire website starting from the given URL. Returns page content, metadata, and links for all discovered pages.

MCP Tool: firecrawl_crawl

Parameters:

  • url (required): Starting URL to crawl
  • limit: Max pages to crawl (default: 100, max: 500)
  • maxDepth: Max link depth from start URL (default: 3)
  • includePaths: Array of glob patterns to include (e.g., ["/blog/*"])
  • excludePaths: Array of glob patterns to exclude (e.g., ["/admin/*", "/api/*"])
  • scrapeOptions.formats: Output formats -- ["markdown", "html", "links"]

SEO Usage Patterns:

  1. Comprehensive audit crawl: Crawl full site, extract all pages for subagent analysis
  2. Section-focused crawl: Use includePaths to audit only /blog/* or /products/*
  3. Broken link detection: Crawl with ["links"] format, check all hrefs for 404s
  4. Content inventory: Extract all page titles, meta descriptions, H1s at scale
  5. SPA/JS-rendered sites: Firecrawl renders JavaScript, solving the Issue #11 problem

Example orchestration for /seo audit:

1. firecrawl_map(url) -> get all URLs (fast, no content)
2. Filter to top 50 most important pages (homepage, key sections)
3. firecrawl_crawl(url, limit=50) -> get full content
4. Feed content to seo-technical, seo-content, seo-schema agents

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.
