gsc-indexing-audit

gsc-indexing-audit is a skill for Claude Code from acamolese/google-search-console-mcp. It costs 64 tokens per session (529 once invoked), scanned A, original, MIT.

A Google Search Console audit procedure for checking which site pages Google has indexed. Google Search Console is Google's service for reporting how its search crawler sees a website.

In plain words
What is it for?
It is for selecting important URLs, inspecting their indexing status, checking submitted sitemaps, and grouping pages by the reason they are not indexed.
Why use it?
It helps identify whether pages are missing because of canonical conflicts, thin content, crawling delays, sitemap problems, or other indexing causes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gsc-indexing-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Indexing audit

1. Choose the URLs

Do not inspect the whole site. Start with the pages that matter:

gsc_query with dimensions="page", period="last_28_days", row_limit=20.

If the user names specific URLs, use theirs instead.

2. Inspect

gsc_indexing_issues with those URLs. Limits worth knowing:

  • 100 URLs per call.
  • The API allows 600 inspections per minute and 2,000 per day per property. On a large site that daily cap is the real constraint; say so before running a big batch.

Then gsc_sitemaps for the submitted sitemaps.

3. Group by cause, not by URL

The coverage_state is what matters, and each value needs a different fix:

  • Duplicate, Google chose different canonical than user — Google disagrees with the declared canonical. Check what it picked (google_canonical against user_canonical) and whether the content is genuinely distinct.
  • Crawled - currently not indexed — Google saw it and passed. This is a content-quality signal, not a technical one. More internal links will not fix a thin page.
  • Discovered - currently not indexed — Google knows the URL but has not fetched it. Usually crawl budget: too many low-value URLs competing for attention.
  • Blocked by robots.txt / noindex — deliberate or a mistake. Confirm which before recommending anything.
  • Page fetch failure / soft 404 — a server problem. Reproduce it before blaming Google.

4. Sitemaps

Report any sitemap with errors or warnings, and compare its submitted count against its indexed count. A wide gap usually means the sitemap lists URLs that redirect, 404 or carry noindex.

5. Deliver

A prioritised list: what is broken, how many pages it affects, what to change, and how to verify. Note that indexing changes take days to weeks to show, so a recheck belongs two to three weeks out, not tomorrow.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
