A skill your agent uses when auditing internal link structure after a URL migration, domain change, or site rebuild.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Technical SEO

What it does

Redirect Chains is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing internal link structure after a URL migration, domain change, or site rebuild. Applies to any site that has had redirects in place for more than a month.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Auditing internal link structure after a URL migration
  • Tasks that involve Technical SEO

Example prompts

  • “/redirect-chains”

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • frontendchecklist.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Redirect Chains loads about 644 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 47 tokens; SKILL.md has 331 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~644
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Internal links that point to redirect URLs add latency, waste crawl budget, and pass less PageRank to the destination than a direct link would—reducing the ranking potential of linked pages.

Quick Reference

  • Internal links should point directly to the final destination URL, not to a URL that redirects
  • Each redirect in a chain dilutes the PageRank passed through it
  • Update internal links after URL migrations to point to the new URLs
  • Use 301 redirects for permanent moves, but then update source links

Check

Crawl internal links across the site. For each <a href='...'> tag, follow the URL and check the HTTP response code. Flag any internal link that resolves to a 301 or 302 redirect rather than a direct 200 response. Report the source page, linked URL, and the final destination URL after following the redirect.

Fix

For each internal link pointing to a redirect URL: update the href attribute to point directly to the final destination URL (the 200-status URL after following all redirects). Keep the redirect in place for external links, but update all internal links to point directly to the canonical-url destination.

Explain

When Googlebot follows a link to a URL that then redirects to another URL, PageRank is partially lost at each hop. Google has stated that redirects dilute PageRank. Additionally, linking to redirect URLs wastes crawl budget since Googlebot must make multiple requests to reach the final content. Updating internal links to point directly to destination URLs passes full PageRank and improves crawl efficiency.

Code Review

For each internal <a href='...'> link, follow the URL and check the HTTP response code. If the response is 301 or 302, record the Location header and continue following. Report all internal links that resolve via one or more redirects before reaching a 200 response. Include: source page, link href, each redirect URL in the chain, and final destination URL.
