[question] 立项按S1（第 1–5 项），然后实现，不要跳过规则和skill中的步骤

[try to solve] Completed docs/2026-08-09-seo-webmaster-tools-survey.md §5 S1 items end-to-end, following tool-creation / tool-i18n-localization / tool-coverage-pass (0b→2→4 gates) and merge:tools / build:site / lint:

meta-serp-preview: catalog shard, en master + 9 locale rewrites, page (char/pixel estimates + desktop/mobile SERP preview), SVG icon; onpage module primarySlugs + remove i18n-taxonomy upcoming; coverage:gate 0b/2/4 green.
schema-jsonld-generator: FAQ/Article/Breadcrumb/Organization JSON-LD (including “breadcrumb needs ≥2 levels” error key); schema module primarySlugs; 10 locales; 0b/2/4 green.
robots-txt-generator: AI crawler User-agents (GPTBot/ClaudeBot/Google-Extended, etc.); crawl module primarySlugs; English title initially failed param-enum directory-cavity gate — retitled to action H1 “Robots.txt Generator — Manage Allow & Disallow Rules for AI Crawlers”; 10 locales; 0b/2/4 green.
sitemap-xml-generator: per-line URL with optional lastmod/changefreq/priority (pipe-separated), URL escaping, lastmod validation, >50k split hint; crawl module primarySlugs; crawl upcoming emptied for ten locales; 10 locales; 0b/2/4 green.
website-headers enhance: Worker uses redirect: manual and follows ≤5 hops returning a redirects chain; results add “SEO header checks” subcard — Cache-Control directive-by-directive, X-Robots-Tag noindex/nofollow/none/max-snippet with block warnings, Redirect 301/302 semantics + cross-host tip; 10 locales +27 keys, keyset 62 identical (script-checked).

Wrap-up: README EN/ZH tool lists +4 tools and refreshed website-headers blurb; tool-inventory-table.md §6 added robots/sitemap rows, fixed schema slug, marked 73/74 shipped, renumbered to 1–161 (script: no dupes/gaps), shipped count 114→118, P0 14→13; meta-serp-preview removed from P0 quick list; schema-jsonld-generator inbound orphan fixed (meta-serp-preview related backlink).

Verification: npm run merge:tools (119 tools / 10 locales), npm run build:site (1420 sitemap URLs), npm run lint:seo (Title/coverage OK, Link validator 0 inbound warn; 15 legacy WARNs on older tools), npm run lint:tool-isolation (skipped without TOOL_SLUG). Each new tool’s 0b/1b/2b rounds and per-locale “round 2 rewritten / spot-check locale round 3” marks written into work-tasks/{slug}/03-locale-briefs.md.
