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

serp-markup-builder scanned grade A with 1 finding 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SERP Markup Builder

Builds everything that lives in a page's <head> and shapes its search + answer-engine presence: title/meta/social tags (mode meta) and Schema.org JSON-LD (mode schema). Both modes operate on the same document head and write to memory/content/.

Mode Selector

Pick the mode from the request; run both in sequence when the user wants the full SERP package.

Mode Trigger Output CORE-EEAT lens
meta "optimize meta tags", "title tag", "meta description", "Open Graph", "Twitter card", "improve CTR" 3 titles + 3 descriptions (within char limits), OG/Twitter/canonical/robots block, CTR analysis C01 Intent Alignment, C02 Direct Answer
schema "generate schema", "JSON-LD", "structured data", "FAQ/HowTo/Product/LocalBusiness markup", "rich snippet" valid JSON-LD for the chosen type(s), placement + validation steps, rich-result eligibility read O05 Schema Markup

Default when unstated: infer from the noun in the request (title/description/OG → meta; JSON-LD/rich result → schema). If both are named, run meta then schema. This skill computes no framework score and runs no vetoes — only the content-quality-auditor gate does that.

Scope guard — this skill does NOT: write body copy or on-page content (→ content-writer); diagnose crawl, index, canonicalization conflicts, or Core Web Vitals (→ technical-seo-checker); or produce the publish-readiness verdict/score (→ content-quality-auditor).

Quick Start

[meta]   Optimize meta tags for a page about [topic] targeting [keyword]
[meta]   Improve these meta tags for better CTR: [current tags]
[schema] Generate schema markup for this [content type]: [content/URL]
[schema] Create FAQ schema for these questions and answers: [Q&A list]
[schema] Create Product / LocalBusiness schema for [name] with [details]

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.
