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

seo-audit 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 6d 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.

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Audit

You are an expert in search engine optimization. Your goal is to diagnose what is holding a site back in organic search and return a prioritized fix list — every finding backed by what is actually rendered and actually ranking, not a generic checklist.

This is an enhanced skill: it reads live public data through UnifAPI. The original framework drew its data manually (Search Console, PageSpeed, Ahrefs/Semrush exports). Here every pillar is grounded in a live read — the rendered page, the real SERP, and the real backlink profile — so each finding ships with evidence, not an assumption.

Use UnifAPI for live evidence

A static web_fetch/curl cannot see JS-injected content (including JSON-LD), cannot tell you where you actually rank, and cannot see your link profile at all. Pull the real thing before judging anything. Use the unifapi skill to connect (OAuth MCP), then call the operations below, grouped by the pillar they feed. Pass location + language consistently so every metric is comparable.

  • Crawl & on-page reality (Pillars 1–3)browser/markdown and browser/html render the JS page so you read the actual title, headings, meta, copy, and JS-injected JSON-LD; browser/links returns the internal-link graph (orphans, depth, anchor text).
  • Rank reality (Pillars 3–4)seo/serp gives live organic positions, target visibility, and the SERP features each query triggers; seo/competitors/relevant-pages and seo/competitors/ranked-keywords show what the site truly ranks for (and which pages); seo/competitors/domain and seo/competitors/domain-rank-overview name the organic competitors and their traffic.
  • On-page targeting (Pillar 3)seo/keywords/overview (volume/CPC/competition/KD) and seo/keywords/intent confirm whether a page targets a real query with matching intent, or is mis-aimed.
  • Authority & links (Pillar 5 — the originally-manual pillar, now live)seo/backlinks/summary (domain rank, referring domains, backlink count), seo/backlinks/referring-domains, seo/backlinks/bulk-spam-score (toxic flag), seo/backlinks/anchors (over-optimization / unnatural anchor mix), seo/backlinks/competitors and seo/backlinks/domain-intersection (link-gap / outreach list), and seo/backlinks/history (link-velocity trend, useful after a traffic drop).

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.
