Our own skill — tested under the same protocol, disclosed. No bench/results/verdict.md exists for this skill; the only evidence is a production run, not a controlled base-vs-skill A/B — translating a 2,900-word article into 10 languages averaged 76,263 tokens and 4m53s per language (range 61k-93k tokens), following the skill's classify-register-protect-translate-anti-AI-pass workflow. That demonstrates real-scale, transparently-reported token cost, but not a proven quality or efficiency win over unguided translation prompting. Protocol test caught real issues in our own repos (dead benchmark links, strict-YAML frontmatter) — fixed and re-verified same day.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 7/10
  • Docs & honesty 4/5

What SEO Translator does

Adds an SEO-aware translation methodology to Claude: per-market register defaults, a never-translate list for brand names/code/URLs, SEO field-length limits for titles and meta descriptions, and a mandatory anti-AI-pattern pass. Distilled from SkillProof's own multi-language site localization work, with real per-language token costs published from a measured run rather than estimated.
