What it does
Noindex In Sitemap is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing an XML sitemap or diagnosing indexing issues. Applies to any site where noindex meta tags or X-Robots-Tag headers may be applied to URLs also listed in the sitemap.
Its SKILL.md is about 580 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`).
It sits in Marketing & SEO, covering Technical SEO and On-page SEO. 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 an XML sitemap
- Diagnosing indexing issues
Example prompts
- “/noindex-in-sitemap”
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
Noindex In Sitemap loads about 580 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 275 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.

Noindex in Sitemap
Listing noindexed pages in your sitemap sends contradictory signals to Googlebot—it wastes crawl budget and may confuse Google into ignoring the noindex directive or spending crawl time on pages you don't want indexed.
Quick Reference
- Never include noindexed pages in your XML sitemap
- The sitemap and noindex directive send contradictory signals to crawlers
- Sitemaps should only list canonical-url, indexable, 200-status URLs
- Remove noindexed URLs from sitemap or remove the noindex directive—pick one
Check
Fetch the XML sitemap(s) and check each listed URL. For each URL, retrieve the page and check for <meta name='robots' content='noindex'> in the <head> or an X-Robots-Tag: noindex HTTP header. Report any URLs present in the sitemap that also carry a noindex directive.
Fix
For each URL that has a noindex directive AND appears in the sitemap: decide whether the page should be indexed. If yes — remove the noindex directive. If no — remove the URL from the sitemap. Never leave both in place.
Explain
The XML sitemap is a recommendation to search engines: 'please crawl and index these pages'. A noindex directive is an instruction: 'do not index this page'. Including noindexed pages in the sitemap creates a contradiction—Google will resolve it by following noindex, but the URL still gets crawled, wasting crawl budget.
Code Review
Fetch each URL in the XML sitemap. For each URL, check the HTTP response for X-Robots-Tag: noindex header, and check the rendered <head> for <meta name='robots' content='noindex'>. Report any URL that appears in the sitemap AND carries a noindex directive. Also check for sitemap entries returning non-200 status codes.
