What it does
Redirect Chain is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing site redirects after URL migrations, domain changes, or CMS upgrades. Applies to any site that has had multiple rounds of structural changes over time.
Its SKILL.md is about 590 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 site redirects after URL migrations
Example prompts
- “/redirect-chain”
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 Chain loads about 594 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 307 words of instructions outside code blocks.
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.

Avoid multi-hop redirect chains
Redirect chains waste crawl budget, reduce PageRank flow to destination pages, and add latency that harms user experience—Googlebot may abandon long chains entirely, leaving destination pages undiscovered.
Quick Reference
- A redirect chain is A→B→C — Googlebot may stop following after 5 hops
- Each hop loses PageRank and adds page load latency
- Flatten chains by pointing A directly to C with a single 301
- Audit after every URL migration to catch newly created chains
Check
Follow all redirect rules configured on the site. Identify any URL where the redirect target itself also redirects (chain of 2+ hops). Report the full chain (URL A → URL B → URL C → final), the number of hops, and the HTTP response code at each step.
Fix
For each redirect chain, update the first redirect to point directly to the final destination URL. Example: if A→B→C, update A's redirect to point directly to C, eliminating the B hop. Verify the chain is gone by following the URL and confirming a single 301 or 302 followed by a 200.
Explain
A redirect chain occurs when page A redirects to page B, which also redirects to page C. Googlebot follows redirect chains up to a certain number of hops (reportedly 5), then stops—meaning the final destination may not be crawled. Each redirect also loses a portion of the PageRank that would have passed through a direct link.
Code Review
Test each redirect rule configured on the server. For each source URL, follow all redirect hops and record the full chain. Flag any chain with 2 or more hops (source → intermediate → final). Check for redirect loops (A→B→A). Verify that the final destination returns 200. Report: source URL, intermediate URLs, number of hops, final URL, and HTTP status at each step.
