name	firecrawl
description	Web search/scrape/crawl via Firecrawl CLI (prefer for live internet lookups).

Firecrawl CLI

Use the firecrawl CLI to fetch and search the web. If the user asks for information from the internet, use Firecrawl skill.

Installation

Check status, auth, and rate limits:

firecrawl --status

Output when ready:

  🔥 firecrawl cli v1.0.2

  ● Authenticated via FIRECRAWL_API_KEY
  Concurrency: 0/100 jobs (parallel scrape limit)
  Credits: 500,000 remaining

• Concurrency: Max parallel jobs. Run parallel operations close to this limit but not above.
• Credits: Remaining API credits. Each scrape/crawl consumes credits.

If not installed: npm install -g firecrawl-cli

Always refer to the installation rules in rules/install.md for more information if the user is not logged in.

Authentication

If not authenticated, run:

firecrawl login --browser

The --browser flag automatically opens the browser for authentication without prompting. This is the recommended method for agents. Don't tell users to run the commands themselves - just execute the command and have it prompt them to authenticate in their browser.

Organization

Create a .firecrawl/ folder in the working directory unless it already exists to store results unless a user specifies to return in context. Add .firecrawl/ to the .gitignore file if not already there. Always use -o to write directly to file (avoids flooding context):

# Search the web (most common operation)
firecrawl search "your query" -o .firecrawl/search-{query}.json

# Search with scraping enabled
firecrawl search "your query" --scrape -o .firecrawl/search-{query}-scraped.json

# Scrape a page
firecrawl scrape https://example.com -o .firecrawl/{site}-{path}.md

Examples:

.firecrawl/search-react_server_components.json
.firecrawl/search-ai_news-scraped.json
.firecrawl/docs.github.com-actions-overview.md
.firecrawl/firecrawl.dev.md

For temporary one-time scripts (batch scraping, data processing), use .firecrawl/scratchpad/:

.firecrawl/scratchpad/bulk-scrape.sh
.firecrawl/scratchpad/process-results.sh

Organize into subdirectories when it makes sense for the task:

.firecrawl/competitor-research/
.firecrawl/docs/nextjs/
.firecrawl/news/2024-01/

Always quote URLs - shell interprets ? and & as special characters.

Scrape - Single page content extraction

# Basic scrape (markdown output)
firecrawl scrape https://example.com -o .firecrawl/example.md

# Get raw HTML
firecrawl scrape https://example.com --html -o .firecrawl/example.html

# Multiple formats (JSON output)
firecrawl scrape https://example.com --format markdown,links -o .firecrawl/example.json

# Main content only (removes nav, footer, ads)
firecrawl scrape https://example.com --only-main-content -o .firecrawl/example.md

# Wait for JS to render
firecrawl scrape https://spa-app.com --wait-for 3000 -o .firecrawl/spa.md

# Extract links only
firecrawl scrape https://example.com --format links -o .firecrawl/links.json

# Include/exclude specific HTML tags
firecrawl scrape https://example.com --include-tags article,main -o .firecrawl/article.md
firecrawl scrape https://example.com --exclude-tags nav,aside,.ad -o .firecrawl/clean.md

firecrawl map https://example.com -o .firecrawl/urls.txt

# Output as JSON
firecrawl map https://example.com --json -o .firecrawl/urls.json

# Search for specific URLs
firecrawl map https://example.com --search "blog" -o .firecrawl/blog-urls.txt

# Limit results
firecrawl map https://example.com --limit 500 -o .firecrawl/urls.txt

# Include subdomains
firecrawl map https://example.com --include-subdomains -o .firecrawl/all-urls.txt

• --sitemap <mode> - include, skip, or only
• --include-subdomains - Include subdomains
• --json - Output as JSON
• -o, --output <path> - Save to file

Reading Scraped Files

NEVER read entire firecrawl output files at once unless explicitly asked or required - they're often 1000+ lines. Instead, use grep, head, or incremental reads. Determine values dynamically based on file size and what you're looking for.

Examples:

# Check file size and preview structure
wc -l .firecrawl/file.md && head -50 .firecrawl/file.md

# Use grep to find specific content
grep -n "keyword" .firecrawl/file.md
grep -A 10 "## Section" .firecrawl/file.md

# Read incrementally with offset/limit
Read(file, offset=1, limit=100)
Read(file, offset=100, limit=100)

Adjust line counts, offsets, and grep context as needed. Use other bash commands (awk, sed, jq, cut, sort, uniq, etc.) when appropriate for processing output.

Format Behavior

• Single format: Outputs raw content (markdown text, HTML, etc.)
• Multiple formats: Outputs JSON with all requested data

# Raw markdown output
firecrawl scrape https://example.com --format markdown -o .firecrawl/page.md

# JSON output with multiple formats
firecrawl scrape https://example.com --format markdown,links -o .firecrawl/page.json

Branding Format v2 (API)

Branding is obtained from the v2 scrape endpoint with formats: ["branding"].

curl -sS -X POST "https://api.firecrawl.dev/v2/scrape" \
  -H "Authorization: Bearer $FIRECRAWL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com","formats":["branding"],"waitFor":10000}' \
  -o ".firecrawl/example-branding.json"

jq -r '.data.colors.primary' .firecrawl/example-branding.json
jq -r '.data.typography.headings[]?' .firecrawl/example-branding.json
jq -r '.data.logo' .firecrawl/example-branding.json

If your firecrawl CLI version supports branding as a format, you can use it; otherwise use the API approach above (don't assume CLI support unconditionally).

Combining with Other Tools

# Extract URLs from search results
jq -r '.data.web[].url' .firecrawl/search-query.json

# Get titles from search results
jq -r '.data.web[] | "\(.title): \(.url)"' .firecrawl/search-query.json

# Extract links and process with jq
firecrawl scrape https://example.com --format links | jq '.links[].url'

# Search within scraped content
grep -i "keyword" .firecrawl/page.md

# Count URLs from map
firecrawl map https://example.com | wc -l

# Process news results
jq -r '.data.news[] | "[\(.date)] \(.title)"' .firecrawl/search-news.json

Parallelization

ALWAYS run multiple scrapes in parallel, never sequentially. Check firecrawl --status for concurrency limit, then run up to that many jobs using & and wait:

# WRONG - sequential (slow)
firecrawl scrape https://site1.com -o .firecrawl/1.md
firecrawl scrape https://site2.com -o .firecrawl/2.md
firecrawl scrape https://site3.com -o .firecrawl/3.md

# CORRECT - parallel (fast)
firecrawl scrape https://site1.com -o .firecrawl/1.md &
firecrawl scrape https://site2.com -o .firecrawl/2.md &
firecrawl scrape https://site3.com -o .firecrawl/3.md &
wait

For many URLs, use xargs with -P for parallel execution:

cat urls.txt | xargs -P 10 -I {} sh -c 'firecrawl scrape "{}" -o ".firecrawl/$(echo {} | md5).md"'
