What is indexing-audit?

A Google Search Console audit of whether a website’s most-visible pages are indexed by Google and available to appear in search results.

Use it to inspect up to 20 high-visibility pages, classify indexing problems, and prioritize fixes such as resolving blocks or canonical mismatches.

It reveals pages that Google excluded, blocked, fetched incorrectly, or assigned a different canonical URL.

indexing-audit — Skill for Claude Code and Codex by Klartika

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Klartika/gsc-mcp-server --skill indexing-audit

Clone the repo

git clone --depth 1 https://github.com/Klartika/gsc-mcp-server

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00330
Opus 5	$0.00015	$0.00165
Sonnet 5	$0.00006	$0.00066
Haiku 4.5	$0.00003	$0.00033

Security

Grade A, and why

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 10d 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.

Origin

This is a copy

95% identical to indexing-audit — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Indexing Audit

Audit the indexing status of the top pages on a site and produce a prioritized action list.

Steps

Call list_properties to confirm the exact site_url.
Call get_advanced_search_analytics with dimensions=page, sort_by=impressions, row_limit=20 to identify the 20 most-visible pages.
Extract the list of page URLs from the results.
Call batch_url_inspection with up to 10 URLs at a time (API limit). Run twice if needed to cover all 20 pages.
Categorize each URL by verdict:
- ✅ Indexed (PASS)
- ⚠️ Soft 404 / Excluded
- ❌ Not indexed / Blocked
- 🔍 Canonical mismatch (Google chose a different canonical)
For each issue, provide the specific coverageState, pageFetchState, or robotsTxtState from the inspection.

Output format

Present as a prioritized action list:

Critical — Not indexed pages that have impressions (visibility being lost)
High — Canonical mismatches on high-traffic pages
Medium — Robots.txt or fetch blocks
Low — Soft exclusions on low-traffic pages

Include a summary table: page URL | verdict | issue | recommended action.

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.
