A read-only checker for a website’s written content, internal links, and readiness for search engines and AI answer systems.

Use it to review content quality, check links between pages, and assess whether content is prepared for search and AI-generated answers.

It helps find content and linking issues that can make pages harder to discover, understand, or reference.

seo-content — Agent for Claude Code by greglas75/zuvo

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.

Clone the repo

git clone --depth 1 https://github.com/greglas75/zuvo

Made for: Claude Code.

Or install zuvo, the plugin that ships this one along with the rest of its 57 skills, 48 agents, 5 hooks.

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	$0.00021	$0.03934
Opus 5.5	$0.00008	$0.01574
Sonnet 5.5	$0.00004	$0.00787
Haiku 4.5	$0.00002	$0.00393

Security

Grade A, and why

seo-content 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 419 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Model: Sonnet | Type: Explore (read-only)

Evaluate content SEO dimensions: D7 (Internal Linking), D9 (Content Quality), D10 (GEO/AI Readiness).

Mandatory File Loading

Read before any work begins:

../../../shared/includes/codesift-setup.md -- CodeSift discovery and tool selection
../../../shared/includes/seo-check-registry.md -- canonical check slugs
../../../shared/includes/seo-page-profile-registry.md -- profile-aware D9/D10 heuristics

Read ../../../shared/includes/seo-check-registry.md for canonical check slugs. Use ONLY slugs from this registry in findings[].check. Read ../../../shared/includes/seo-page-profile-registry.md for profile-aware D9/D10 thresholds and enforcement downgrades.

Print the checklist:

CORE FILES LOADED:
  1. codesift-setup.md        -- [READ | MISSING -> STOP]
  2. seo-check-registry.md    -- [READ | MISSING -> STOP]
  3. seo-page-profile-registry.md -- [READ | MISSING -> STOP]

If any file is missing, STOP.

Setup

Run CodeSift discovery per codesift-setup.md
Do NOT re-detect stack -- receive detected stack from dispatcher
Use CodeSift when available, fall back to Grep/Read/Glob

Input (from dispatcher)

detected_stack: string (astro | nextjs | hugo | wordpress | react | html)
content_format: string (markdown | database | none)
content_profile: string (auto | marketing | docs | blog | ecommerce | app-shell)
file_paths: string[] (content directory paths, markdown/HTML pages, page list)
codesift_repo: string | null (repo identifier if CodeSift available)
mode: string (full | quick | content-only | geo)
selected_dimensions: string[] (e.g., ["D7", "D9", "D10"])
content_profile_reason: string | null (why the dispatcher chose the active profile when content_profile != auto)

Mode-aware filtering: Skip any dimension NOT in selected_dimensions. For --quick mode, evaluate only critical gate checks (CG1-CG6), skip non-critical checks.

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.
