Date: 2026-08-09 21:55 Summary: Shipped S2’s five SEO tools (on-page-seo-checker, open-graph-preview, utm-builder, hreflang-generator, meta-tag-generator) with phase=all green.
[question] 分步骤立项工具：on-page-seo-checker，open-graph-preview，utm-builder，hreflang-generator，meta-tag-generator；然后分步骤实现；
[try to solve] Completed five S2 tools via tool-creation / work-tasks, each through rounds 0b→1b→2→2b→3 and phase=all gates:
on-page-seo-checker
- Worker API
/api/tools/on-page-seo(fetch URL HTML; private-network block / timeout / 2MB cap); exportsparseUrlOrThrow/isBlockedHostnamefor reuse. - Dual mode: paste HTML (DOMParser local audit) or fetch URL; checks title/description/H1/canonical/robots/OG/JSON-LD/mixed content/render-blocking; canonical self-ref uses finalUrl.
- Fixed sample JSON-LD with unescaped
</script>that truncated the inline script. - zh title: On-Page SEO Checker (localized); en: “On-Page SEO Checker — Find and fix page tag issues” (outcome-oriented, avoid param enum).
open-graph-preview
- Worker API
/api/tools/open-graph-preview(reuses onPageSeo helpers). - Dual mode: paste og/twitter tags or fetch URL; parse into Facebook / X / WhatsApp cards + missing-field table + og:image size/ratio.
- Placed in the social module; removed “Open Graph preview” from social upcoming.
utm-builder
- Pure client (
localProcessing: true); form builds UTM links: auto scheme, merge params (same name replaces), encodeURIComponent, hash kept at end, param detail table + copy. - Placed in the growth module; removed “UTM builder” from growth upcoming.
hreflang-generator
- Pure client; language-code + URL line list; validate BCP 47; bare URLs get https; three output tabs (
<link>/ HTTP Link header / sitemap xhtml:link); per-URL self-ref + optional x-default. - Two logic fixes: invalid lang errors lost under renderOutput → collect via pendingErrors;
{lang} {url}with schemeless URL skipped the whole line → parse by language-code first. - Placed in the growth module; cleared growth upcoming (hreflang + UTM both shipped).
meta-tag-generator
- Pure client; title/desc/canonical/robots(select)/OG → full head fragment; soft length hints (title 60 / desc 160), escapeHtml on all fields, schemeless canonical warned yellow, empty fields skipped, copy button.
- Master title failed the param-enum gate (“Create title, description & OG tags”) → outcome “Generate complete page head tags”; synced 02/03 and zh/es/ja direction.
- Placed in the onpage module (also added previously missing on-page-seo-checker); removed “Meta tag generator” from onpage upcoming.
Global wrap-up
- merge:tools: 124 tools / 10 locales; per-tool keysets match (on-page 95 / og 76 / utm 75 / hreflang 53 / meta 67).
- Fixed lint:seo inbound orphans: sitemap-xml-generator related → hreflang-generator, hreflang-generator related → utm-builder → 0 inbound warn.
- build:site OK (sitemap 1470 URLs); esbuild compiled 5 pages + 2 Workers + index.ts; Node DOM mocks for sample auto-gen and key interactions.
- README EN/ZH lists +5 entries; inventory §6 rows 78–80 marked shipped, added 81/82, shipped count 118→123, index 1–163, open P2 →~78.
