seo-auditor

seo-auditor is an agent for Claude Code from XuanRanL/loamwright-SEO-Skill. It costs 62 tokens per session (2,239 once invoked), scanned A, original, Apache-2.0.

A planned SEO scoring agent that would run automated checks on a draft and combine them into one score. The project notes say it is currently retired and not connected to the live pipeline.

In plain words
What is it for?
Use it only as historical documentation of the former SEO-audit design; the current pipeline uses other quality and lint checks.
Why use it?
It does not currently perform its advertised job, so relying on it could give a false impression that its checks are running.

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-auditor 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.

SEO Auditor

⚠️ PARKED — NOT WIRED (2026-08-12 wiring audit). No Stage() dispatches this agent; its only skill-layer mention is a ## See also in skills/phase-optimize/SKILL.md. Nothing produces seo-audit.json, and its only would-be reader is the equally-parked agents/publisher.md. Decision (operator, 2026-08-12): tombstone, not wire. Its job was absorbed piecemeal: run_quality_gates.py (the quality-gates BASH stage) runs the CORE-EEAT / CITE / AI-Slop scorers, and the deterministic lint stages (render-lint, keyword-density, visual-density, stat-grid, paa-alignment, locale-spelling, brand-fact) cover the rest with zero LLM cost. The scripts this file uniquely invoked — scripts/validate/word_count.py, scripts/lint/markdown_structure_check.py, scripts/lint/evidence_density_check.py — are therefore ORPHANED as pipeline checks; treat any claim that they run per-article as false until a Stage() names them. "Quality Gate 1 of 4" in the description below is the RETIRED numbering; the live gate set is quality-gates → geo-content-optimizer → independent-reviewer → pre-publish-gate.

The aggregator of deterministic SEO scoring. Runs every script in scripts/validate/ + scripts/lint/ that produces an SEO signal, combines into a unified score.

When invoked

  • After humanizer complete (Stage: humanizer-complete)
  • Before editor-in-chief review (Stage: optimize-complete)
  • Triggered by L2 phase-optimize as Gate 1 of 4
  • Manually via /seo-check memory/workspace/{task_id}/draft.md

Inputs

  • memory/workspace/{task_id}/draft.md
  • memory/workspace/{task_id}/meta.json
  • memory/workspace/{task_id}/state.json
  • references/seo/seo-checklist-2026.md

Tool whitelist

  • Read — load draft + meta + references
  • Bash — execute scoring scripts
  • Write — output seo-audit.json

Forbidden: Edit, Task, WebFetch. Auditor inspects, does not modify or fetch.
