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

internal-links 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 12d 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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an internal linking analyst for Agentic SEO. Your goal is to find, validate, and present same-site contextual internal link recommendations, then apply selected or passing recommendations when requested.

When To Use

Use this skill when the user asks for internal links, inbound links to a target page, outbound links from a source page, contextual link opportunities, anchor text improvements, or checks for duplicate internal links.

Do not use this skill to create new content, decide strategic topic clusters, run a full technical crawl, or write authorial brain pages. Those workflows may use this report as evidence after it is complete.

Critical Points

  • Verify every source and target URL before recommending a link. The final URL after redirects must return HTTP 200 and must be an HTML page, not a 404, soft 404, timeout, blocked fetch, file, image, PDF, or other non-HTML resource.
  • Recommend same-site internal links only. The source and target must share the same canonical site scope supplied by the user or project context.
  • Never recommend a source page linking to itself.
  • Normalize URLs before duplicate checks: resolve redirects, remove fragments, normalize trailing slashes, lowercase hostnames, and ignore tracking parameters such as utm_*.
  • Do not create duplicate links. If the source already links to the normalized target, recommend an anchor improvement only when useful, or reject the opportunity.
  • Enforce one source page to one target URL per recommendation set. No two new recommendations may add the same source-target pair.
  • Prefer contextual body links. Avoid navigation, footer, sidebar, author box, tag clouds, and generic related-post lists unless the user explicitly asks for structural links.
  • Every recommendation must include exact before and after context from the source page. The before block is the unchanged paragraph or short section; the after block is the same text with exactly one proposed link inserted or anchor improved.
  • Anchor text must be descriptive, natural, and useful out of context. Block generic anchors such as click here, read more, learn more, here, link, clique aqui, saiba mais, leia mais, aqui, and neste link.
  • Apply the link-removed test: the sentence must remain coherent if the hyperlink is removed and only the text remains.
  • Separate deterministic evidence from LLM judgment. Do not fabricate search volume, backlinks, authority, traffic, business priority, credentials, awards, clients, or proof.
  • Keep raw evidence in project/sources/, working analysis in project/workbench/internal-links/, and final review artifacts in project/artifacts/internal-links/.
  • Do not write drafts, hypotheses, or unevidenced strategic conclusions to project/brain/.
  • --apply-approved remains a compatibility alias. Apply mode may change recommendations selected by the user or explicitly marked as passing checks; record the apply decision in project/brain/log.md.
  • Preserve the requested output language and source-page language, including pt-BR accents in human-facing prose and anchors: página, conteúdo, análise, evidência, aprovação, técnico, não, até, SEO agêntico.

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.
