When your agent uses it
- Auditing slow page loads
- Rendering delays related to Avoid JavaScript-based redirects
Example prompts
- “/js-redirects”
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
JS Redirects loads about 427 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 157 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 JavaScript-based redirects
JavaScript redirects force an additional round-trip after the initial page load, significantly increasing the time users spend waiting for content.
Quick Reference
- Use 301 or 302 server-side redirects instead of
window.location - JS redirects delay page load as the browser must first download and execute the script
- Client-side redirects can negatively impact SEO and indexability
Check
Check the project for instances where JavaScript is being used for page-level redirects (e.g., window.location).
Fix
Replace JavaScript-based redirects with server-side 301 or 302 redirects in your web server or edge configuration.
Explain
Explain why server-side redirects are faster and more SEO-friendly than client-side JavaScript redirects.
Code Review
Review the routes, assets, and loading behavior that affect Avoid JavaScript-based redirects. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue.
