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. ### Links squirrelscan website is at https://squirrelscan.com documentation (including rule references) are at docs.squirrelscan.com You can look up the docs for any rule with this template: https://docs.squirrelscan.com/rules/{rule_category}/{rule_id} example: https://docs.squirrelscan.com/rules/links/external-links ### What This Skill Does This skill enables AI agents to audit websites for over 230 rules in 21 categories, including: SEO issues: Meta tags, titles, descriptions, canonical URLs, Open Graph tags Technical problems: Broken links, redirect chains, page speed, mobile-friendliness Performance: Page load time, resource usage, caching Content quality: Heading structure, image alt text, content analysis Security: Leaked secrets, HTTPS usage, security headers, mixed content Accessibility: Alt text, color contrast, keyboard navigation Usability: Form validation, error handling, user flow Links: Checks for broken internal and external links E-E-A-T: Expertise, Experience, Authority, Trustworthiness User Experience: User flow, error handling, form validation Mobile: Checks for mobile-friendliness, responsive design, touch-friendly elements Crawlability: Checks for crawlability, robots.txt, sitemap.xml and more Schema: Schema.org markup, structured data, rich snippets Legal: Compliance with legal requirements, privacy policies, terms of service Social: Open graph, twitter cards and validating schemas, snippets etc. Url Structure: Length, hyphens, keywords Keywords: Keyword stuffing Content: Content structure, headings Images: Alt text, color contrast, image size, image format Local SEO: NAP consistency, geo metadata Video: VideoObject schema, accessibility and more The audit crawls the website, analyzes each page against audit rules, and returns a comprehensive report with: Overall health score (0-100) Category breakdowns (core SEO, technical SEO, content, security) Specific issues with affected URLs Broken link detection Actionable recommendations Rules have levels of error, warning and notice and also have a rank between 1 and 10 ### When to Use Use this skill when you need to: Analyze a website's health Debug technical SEO issues Fix all of the issues mentioned above Check for broken links Validate meta tags and structured data Generate site audit reports Compare site health before/after changes Improve website performance, accessibility, SEO, security and more. You should re-audit as often as possible to ensure your website remains healthy and performs well. ### Prerequisites This skill requires the squirrel CLI installed and in PATH. Install: squirrelscan.com/download Verify: squirrel --version ### Setup Run squirrel init to create a squirrel.toml config in the current directory. If none exists, create one and specify a project name: squirrel init -n my-project # overwrite existing config squirrel init -n my-project --force ### Intro 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 --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 --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) Iterate - fix batch → re-audit → present results → propose next batch Pause for judgment - broken links, structural changes, and anything ambiguous should be flagged for user review Show before/after - present score comparison after each fix batch Iteration Loop: After fixing a batch of issues, re-audit and continue fixing until: Score reaches target (typically 85+), OR Only issues requiring human judgment remain (e.g., "should this link be removed?") Treat all fixes equally: Code changes and content changes are equally important. Parallelize content fixes: For issues affecting multiple files: Spawn subagents to fix in parallel Example: 7 files need alt text → spawn 1-2 agents to fix all Example: 30 files have heading issues → spawn agents to batch edit Completion criteria: ✅ All errors fixed ✅ All warnings fixed (or documented as requiring human review) ✅ Re-audit confirms improvements ✅ Before/after comparison shown to user After fixes are applied, ask the user if they'd like to review the changes. ### Score Targets Starting ScoreTarget ScoreExpected Work< 50 (Grade F)75+ (Grade C)Major fixes50-70 (Grade D)85+ (Grade B)Moderate fixes70-85 (Grade C)90+ (Grade A)Polish> 85 (Grade B+)95+Fine-tuning A site is only considered COMPLETE and FIXED when scores are above 95 (Grade A) with coverage set to FULL (--coverage full). ### Issue Categories CategoryFix ApproachParallelizableMeta tags/titlesEdit page components or metadataNoStructured dataAdd JSON-LD to page templatesNoMissing H1/headingsEdit page components + content filesYes (content)Image alt textEdit content filesYesHeading hierarchyEdit content filesYesShort descriptionsEdit content frontmatterYesHTTP→HTTPS linksFind and replace in contentYesBroken linksManual review (flag for user)No For parallelizable fixes: Spawn subagents with specific file assignments. ### Content File Fixes Many issues require editing content files. These are equally important as code fixes: Image alt text: Add descriptive alt text to images Heading hierarchy: Fix skipped heading levels Meta descriptions: Extend short descriptions in frontmatter HTTP links: Update insecure links to HTTPS ### Parallelizing Fixes with Subagents When the user approves a batch of fixes, you can use subagents to apply them in parallel: Ask the user first — always confirm which fixes to apply before spawning subagents Group 3-5 files per subagent for the same fix type Only parallelize independent files (no shared components or config) Spawn multiple subagents in a single message for concurrent execution ### Advanced Options Audit more pages: squirrel audit https://example.com --max-pages 200 Force fresh crawl (ignore cache): squirrel audit https://example.com --refresh Resume interrupted crawl: squirrel audit https://example.com --resume Verbose output for debugging: squirrel audit https://example.com --verbose ### Audit Command Options OptionAliasDescriptionDefault--format -f Output format: console, text, json, html, markdown, llmconsole--coverage -C Coverage mode: quick, surface, fullsurface--max-pages -m Maximum pages to crawl (max 5000)varies by coverage--output -o Output file path---refresh-rIgnore cache, fetch all pages freshfalse--resume-Resume interrupted crawlfalse--verbose-vVerbose outputfalse--debug-Debug loggingfalse--trace-Enable performance tracingfalse--project-name -n Override project namefrom config ### Coverage Modes Choose a coverage mode based on your audit needs: ModeDefault PagesBehaviorUse Casequick25Seed + sitemaps only, no link discoveryCI checks, fast health checksurface100One sample per URL patternGeneral audits (default)full500Crawl everything up to limitDeep analysis Surface mode is smart - it detects URL patterns like /blog/{slug} or /products/{id} and only crawls one sample per pattern.

Solution: Install squirrel: squirrelscan.com/download Ensure ~/.local/bin is in PATH Verify: squirrel --version ### Permission denied If squirrel is not executable, ensure the binary has execute permissions. Reinstalling from squirrelscan.com/download will fix this. ### Crawl timeout or slow performance For very large sites, the audit may take several minutes. Use --verbose to see progress: squirrel audit https://example.com --format llm --verbose ### Invalid URL Ensure the URL includes the protocol (http:// or https://): # ✗ Wrong squirrel audit example.com # ✓ Correct squirrel audit https://example.com ### How It Works Crawl: Discovers and fetches pages starting from the base URL Analyze: Runs audit rules on each page External Links: Checks external links for availability Report: Generates LLM-optimized report with findings The audit is stored in a local database and can be retrieved later with squirrel report commands. ### Additional Resources Output Format Reference: OUTPUT-FORMAT.md squirrelscan Documentation: https://docs.squirrelscan.com CLI Help: squirrel audit --help ## Trust - Source: tencent - Verification: Indexed source record - Publisher: nc9 - Version: 1.0.4 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-11T16:26:02.115Z - Expires at: 2026-05-18T16:26:02.115Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/squirrelscan) - [Send to Agent page](https://openagent3.xyz/skills/squirrelscan/agent) - [JSON manifest](https://openagent3.xyz/skills/squirrelscan/agent.json) - [Markdown brief](https://openagent3.xyz/skills/squirrelscan/agent.md) - [Download page](https://openagent3.xyz/downloads/squirrelscan)
