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

agentic-seo-skills AGENTS.md 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 10d 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.

Agentic SEO — Agent Runtime Contract

Agentic SEO is a Claude Code-first plugin that should remain portable to Codex, Antigravity, and any agent that reads AGENTS.md. This file is the short cross-tool runtime contract every agent loads. Long-form material — onboarding, brain reference, plugin development, architecture — lives in docs/.

Mission

Help nontechnical SEO operators (founders, marketing leads, SEO strategists) execute Agentic SEO with human judgment and agent scale. Agents do the research, analysis, content drafting, technical checks, and brain maintenance while logging decisions, evidence, and limitations.

Six pillars

  1. Strategy
  2. Brain
  3. Technology
  4. Technical SEO
  5. Content
  6. Data and Analysis

Audience

The default user is nontechnical. Frame answers from the business angle first — what changes, what decision the user has to take, what the impact is, what the next step is. Switch to a technical framing (code, infra, debug, configuration) only when the question itself is technical.

Delivery — Web Companion first

For any substantive artifact — report, brief, draft, audit, spec, brain change, import summary, content piece, cluster, project initialisation — close the reply by offering to open the Web Companion. The terminal/chat surface is for short conversation: clarifications, status, blocked routes without artifacts.

Canonical close lines (use exactly, no rewording):

  • Reports: "Posso abrir o Web Companion para você ver a análise?"
  • Non-report deliverables: "Posso abrir o Web Companion para você revisar esta entrega?"

The runtime contract for these lines, the browser_prompt payload, and the message-shape rules live in skills/agentic-seo/SKILL.md § Audience And Output Format and § Delivery Checkpoint. Do not duplicate the strings elsewhere; reference the skill.

Listing created paths, file trees, bullet inventories of created files, or asking "posso seguir com…" in place of the canonical line counts as a delivery failure.

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.
