creo-gsc

creo-gsc is a skill for Claude Code from oyusypenko/creo. It costs 108 tokens per session (2,000 once invoked), scanned A, original, MIT.

A toolkit for checking how a website appears in Google Search and for auditing its search-engine setup. Google Search Console is Google's service for viewing search traffic, indexing, and site problems.

In plain words
What is it for?
Use it to inspect whether pages are indexed, review clicks and impressions, check page titles and headings, validate structured data and language links, test security headers, and audit a whole site.
Why use it?
It brings search data and many technical checks into one workflow, so you do not have to inspect indexing, page details, structured data, and security settings separately.

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is GSC_SITE_URL="sc-domain:example.com" node scripts/gsc_ui_export.mjs --setup.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

creo-gsc 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 11d 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.

Creo GSC - Google Search Console & SEO Analysis

Commands

Command Description
/creo gsc list-sites List all Search Console properties
/creo gsc inspect <url> Inspect a URL's indexation status
/creo gsc analytics Get search analytics (clicks, impressions, CTR)
/creo gsc security <url> Analyze HTTP security headers
/creo gsc onpage <url> On-page SEO analysis (title, meta, headings, images)
/creo gsc schema <url> Validate structured data (JSON-LD)
/creo gsc hreflang <url> Validate hreflang implementation
/creo gsc full-seo <url> Run all 9 page analyzers on a URL
/creo gsc site-audit <url> Crawl and audit entire website
/creo gsc ui-export Export Page Indexing drilldown CSVs via Playwright (UI-only data the API cannot enumerate)
/creo gsc validate-fix Click GSC's "Validate Fix" button via Playwright (no API exists for it)
/creo gsc open [<surface>] Open a Search Console report in the user's browser (overview, performance, indexing, sitemaps, settings, inspect ) and read/operate it together

Browser-first operation

The API is preferred for data it can serve, but this skill is NOT API-only. With browser tools available, open Search Console directly in the user's signed-in Chrome — navigate to the exact report via the deep-link map in the agent doc, read it, click drilldowns, export CSVs, and perform configuration (submit sitemaps, manage users) together with the user. The user must already be signed in; never attempt a scripted Google login; confirm before any destructive click. Use the UI as ground truth whenever API results look wrong.

Running gsc_toolkit CLI Commands

The toolkit is a Python package. All commands are executed via:

# Find the installed toolkit
GSC_DIR="${HOME}/.claude/skills/creo-gsc"

# Activate the virtual environment (if installed with venv)
source "${GSC_DIR}/.venv/bin/activate" 2>/dev/null || true

# Run commands
python -m gsc_toolkit <command> [options]

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.
