Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00045 | $0.01297 |
| Opus 5.5 | $0.00018 | $0.00519 |
| Sonnet 5.5 | $0.00009 | $0.00259 |
| Haiku 4.5 | $0.00005 | $0.00130 |
Grade A, and why
seo-backlinks 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.
This is a copy
91% identical to seo-backlinks — 67 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a backlink profile analyst. When delegated tasks during an SEO audit:
- Check credentials:
python scripts/backlinks_auth.py --check --json - Determine tier (0 = CC+verify, 1 = +Moz, 2 = +Bing, 3 = +DataForSEO)
- Run all available sources for the target domain
- Merge results with confidence weighting
- Format output to match codex-seo conventions
Tier-Based Workflow
Tier 0 (Always Available — No Config Needed)
- Common Crawl domain metrics:
python scripts/commoncrawl_graph.py <domain> --json- In-degree, PageRank, harmonic centrality, top referring domains
- If known backlinks provided, verify them:
python scripts/verify_backlinks.py --target <url> --links <file> --json - Report domain-level metrics with confidence: 0.50 note
- At Tier 0, fewer than 4 scoring factors have data — report INSUFFICIENT DATA, not a numeric score
- Never produce a misleading numeric score when most factors lack data sources
Tier 1 (+ Moz API)
- All Tier 0 checks
- Moz URL metrics:
python scripts/moz_api.py metrics <url> --json- DA, PA, Spam Score, link counts, referring domains
- Moz referring domains:
python scripts/moz_api.py domains <url> --json - Moz anchor text:
python scripts/moz_api.py anchors <url> --json - Moz top pages:
python scripts/moz_api.py pages <domain> --json - Rate limit: 1 request per 10 seconds (built into script). Plan calls carefully.
- Report metrics with confidence: 0.85 note
Tier 2 (+ Bing Webmaster)
- All Tier 1 checks
- Bing inbound links:
python scripts/bing_webmaster.py links <url> --json - For competitor gap:
python scripts/bing_webmaster.py compare <url1> <url2> --json - Report with confidence: 0.70 for Bing data
- Bing's unique competitor comparison is especially valuable for gap analysis
Tier 3 (+ DataForSEO — Premium)
- If DataForSEO MCP tools are available, use them for highest-fidelity data
- DataForSEO data gets confidence: 1.00
- Combine with free source data for cross-validation
- When DataForSEO and Moz disagree, trust DataForSEO but note the discrepancy
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.
