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

seo 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 5d 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.

Origin

This is a copy

95% identical to seo — 1 line 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.

The opening of the file, as written. The whole thing — 371 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO Skill (Agentic / Claude / Codex)

LLM-first SEO analysis skill with 16 specialized sub-skills, 10 specialist agents, and 89 scripts for website, blog, and GitHub repository optimization.

Deterministic Trigger Mapping

For prompt reliability in Codex/agent IDEs, map common user wording to a fixed workflow:

  • If user says perform seo analysis on <url> (or similar generic SEO request with a URL), treat it as a single-URL full audit.
  • If no explicit sub-skill is specified, run the full/page audit path with LLM-first reasoning and script-backed evidence.
  • For full/page audits, always produce:
    • FULL-AUDIT-REPORT.md (detailed findings)
    • ACTION-PLAN.md (prioritized fixes)
  • If generate_report.py is run, also return the saved HTML path (for example SEO-REPORT.html).

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.
