Website Audit Skill
Audit websites for SEO, technical, content, performance and security issues using the squirrelscan cli.
squirrelscan provides a cli tool squirrel - available for macos, windows and linux. It carries out extensive website auditing
by emulating a browser, search crawler, and analyzing the website's structure and content against over 230+ rules.
It will provide you a list of issues as well as suggestions on how to fix them.
There are three processes that you can run and they're all cached in the local project database:
crawl - subcommand to run a crawl or refresh, continue a crawl
analyze - subcommand to analyze the crawl results
report - subcommand to generate a report in desired format (llm, text, console, html etc.)
the 'audit' command is a wrapper around these three processes and runs them sequentially:
squirrel audit https://example.com --format llm
YOU SHOULD always prefer format option llm - it was made for you and provides an exhaustive and compact output format.
FIRST SCAN should be a surface scan, which is a quick and shallow scan of the website to gather basic information about the website, such as its structure, content, and technology stack. This scan can be done quickly and without impacting the website's performance.
SECOND SCAN should be a deep scan, which is a thorough and detailed scan of the website to gather more information about the website, such as its security, performance, and accessibility. This scan can take longer and may impact the website's performance.
If the user doesn't provide a website to audit, ask which URL they'd like audited.
You should PREFER to audit live websites - only there do we get a TRUE representation of the website and performance or rendering issuers.
If you have both local and live websites to audit, prompt the user to choose which one to audit and SUGGEST they choose live.
You can apply fixes from an audit on the live site against the local code.
When planning scope tasks so they can run concurrently as sub-agents to speed up fixes.
When implementing fixes take advantage of subagents to speed up implementation of fixes.
After applying fixes, verify the code still builds and passes any existing checks in the project.
Basic Workflow
The audit process is two steps:
Run the audit (saves to database, shows console output)
Export report in desired format
# Step 1: Run audit (default: console output)
squirrel audit https://example.com
# Step 2: Export as LLM format
squirrel report <audit-id> --format llm
Regression Diffs
When you need to detect regressions between audits, use diff mode:
# Compare current report against a baseline audit ID
squirrel report --diff <audit-id> --format llm
# Compare latest domain report against a baseline domain
squirrel report --regression-since example.com --format llm
Diff mode supports console, text, json, llm, and markdown. html and xml are not supported.
Running Audits
When running an audit:
Present the report - show the user the audit results and score
Propose fixes - list the issues you can fix and ask the user to confirm before making changes
Parallelize approved fixes - use subagents for bulk content edits (alt text, headings, descriptions)
Surface mode is smart - it detects URL patterns like /blog/{slug} or /products/{id} and only crawls one sample per pattern. This makes it efficient for sites with many similar pages (blogs, e-commerce).
# Quick health check (25 pages, no link discovery)
squirrel audit https://example.com -C quick --format llm
# Default surface audit (100 pages, pattern sampling)
squirrel audit https://example.com --format llm
# Full comprehensive audit (500 pages)
squirrel audit https://example.com -C full --format llm
# Override page limit for any mode
squirrel audit https://example.com -C surface -m 200 --format llm
When to use each mode:
quick: CI pipelines, daily health checks, monitoring
surface: Most audits - covers unique templates efficiently
full: Before launches, comprehensive analysis, deep dives
# User asks: "Check squirrelscan.com for SEO issues"
squirrel audit https://squirrelscan.com --format llm
Example 2: Deep Audit for Large Site
# User asks: "Do a thorough audit of my blog with up to 500 pages"
squirrel audit https://myblog.com --max-pages 500 --format llm
Example 3: Fresh Audit After Changes
# User asks: "Re-audit the site and ignore cached results"
squirrel audit https://example.com --refresh --format llm
Example 4: Two-Step Workflow (Reuse Previous Audit)
# First run an audit
squirrel audit https://example.com
# Note the audit ID from output (e.g., "a1b2c3d4")# Later, export in different format
squirrel report a1b2c3d4 --format llm
Output
On completion give the user a summary of all of the changes you made.
