sv-content-quality

sv-content-quality is a skill for Claude Code, Codex from seovendorco/sv-mcp-skills. It costs 53 tokens per session (400 once invoked), scanned A, original, MIT.

A tool that scores a live web page against search-quality criteria, including helpful content and E-E-A-T, which means experience, expertise, authoritativeness, and trustworthiness. It can also compare two public pages.

In plain words
What is it for?
Use it after publishing a page or when reviewing an existing one. Give it a target keyword and one or two URLs to receive scored criteria and explanations.
Why use it?
A draft cannot be checked directly because the tool needs a public URL. The written reasons behind each score help identify what to revise instead of relying on one overall number.

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

sv-content-quality 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 today.

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

SV Content Quality: content-quality

MCP tool: content-quality · Mode: synchronous API reference: Content Quality

When to use this

Use to score a specific published page against Google's helpful-content and E-E-A-T signals, typically right after a draft goes live or on an existing page. Pass a second URL to compare two pages head to head.

Parameters

Parameter Required Notes
keyword yes 4 to 300 characters.
url yes The page to evaluate, max 300 characters.
url_b no A second page to compare against, max 300 characters.

Example call

{ "keyword": "white label seo", "url": "https://example.com/white-label-seo" }

Result

Up to 15 scored criteria per URL (30 when url_b is set). Each has a number, a score from 0 to 100, and a written reason.

Chaining

sv-prose → publish → sv-content-quality → revise if scores are weak → sv-core-analysis is a solid quality gate.

Gotchas

  • It needs a live, public URL. There is no way to pass raw text, so a draft has to be published (or hosted somewhere reachable) first.
  • Treat the scores as a prompt to read each reason, not as one pass or fail number.
  • keyword must be at least 4 characters.
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.
