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

backlink-analysis 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 7d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guides backlink profile analysis: assessing quality, identifying issues, and planning improvements.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope (Off-Page SEO)

  • Backlink audit: Analyze profile; toxic links; competitive analysis
  • Authority Score: Monitor domain/page authority; referring domains

Initial Assessment

Identify:

  1. Domain: Site to analyze
  2. Tool access: SEO tools (e.g. Ahrefs, Semrush) or free alternatives
  3. Goals: Audit for issues, competitive analysis, or growth planning

Key Metrics

Metric Meaning
Referring domains Number of unique sites linking
Backlinks Total number of links
Domain Rating (DR) / Domain Authority (DA) Domain strength score
Anchor text distribution Mix of branded, generic, exact match
Link velocity Rate of new links over time

Analysis Framework

1. Quality Assessment

  • Relevance: Do links come from related niches?
  • Authority: Are referring domains trusted?
  • Context: Editorial vs. footer/sidebar links?
  • Anchor text: Natural or over-optimized?

2. Risk Signals

Signal Action
Toxic links Consider disavow (use cautiously)
Spammy anchors Diversify anchor text naturally
Link schemes Remove or disavow
Sudden spike Investigate; may trigger penalty

3. Competitive Comparison

  • Compare backlink profile to competitors
  • Identify link gaps (sites linking to competitors but not you)
  • Find link opportunities from competitor backlinks
  • See competitor-research for full methodology

Disavow File

  • Use only when necessary (manual penalty, toxic links)
  • Submit via Google Search Console (see google-search-console for Links report and disavow submission)
  • Caution: Over-disavowing can harm; use sparingly
  • References: Google Disavow

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.
