name	tavily-crawl
description	Crawl websites and extract content from multiple pages via the Tavily CLI. Use this skill when the user wants to crawl a site, download documentation, extract an entire docs section, bulk-extract pages, save a site as local markdown files, or says "crawl", "get all the pages", "download the docs", "extract everything under /docs", "bulk extract", or needs content from many pages on the same domain. Supports depth/breadth control, path filtering, semantic instructions, and saving each page as a local markdown file.

tavily crawl

Crawl a website and extract content from multiple pages. Supports saving each page as a local markdown file.

Before running any command

If tvly is not found on PATH, install it first:

curl -fsSL https://cli.tavily.com/install.sh | bash && tvly login

Do not skip this step or fall back to other tools.

See tavily-cli for alternative install methods and auth options.

When to use

• You need content from many pages on a site (e.g., all /docs/)
• You want to download documentation for offline use
• Step 4 in the workflow: search -> extract -> map -> crawl -> research

Quick start

# Basic crawl
tvly crawl "https://docs.example.com" --json

# Save each page as a markdown file
tvly crawl "https://docs.example.com" --output-dir ./docs/

# Deeper crawl with limits
tvly crawl "https://docs.example.com" --max-depth 2 --limit 50 --json

# Filter to specific paths
tvly crawl "https://example.com" --select-paths "/api/.*,/guides/.*" --exclude-paths "/blog/.*" --json

# Semantic focus (returns relevant chunks, not full pages)
tvly crawl "https://docs.example.com" --instructions "Find authentication docs" --chunks-per-source 3 --json

--json	Structured JSON output

Crawl for context vs. data collection

For agentic use (feeding results to an LLM):

Always use --instructions + --chunks-per-source. Returns only relevant chunks instead of full pages - prevents context explosion.

tvly crawl "https://docs.example.com" --instructions "API authentication" --chunks-per-source 3 --json

For data collection (saving to files):

Use --output-dir without --chunks-per-source to get full pages as markdown files.

tvly crawl "https://docs.example.com" --max-depth 2 --output-dir ./docs/

Tips

• Start conservative - --max-depth 1, --limit 20 - and scale up.
• Use --select-paths to focus on the section you need.
• Use map first to understand site structure before a full crawl.
• Always set --limit to prevent runaway crawls.
