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.

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 | $0.00065 | $0.00745 |
| Opus 5 | $0.00032 | $0.00373 |
| Sonnet 5 | $0.00013 | $0.00149 |
| Haiku 4.5 | $0.00006 | $0.00075 |
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.

SEO Off-Page: Backlink Analysis
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:
- Domain: Site to analyze
- Tool access: SEO tools (e.g. Ahrefs, Semrush) or free alternatives
- 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
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.
