Generates fast, SEO-optimized static HTML landing pages targeting 100/100 PageSpeed (LCP < 2.5s, INP < 100ms, CLS < 0.1), full schema.org JSON-LD, AVIF images, critical CSS, zero external dependencies. Use when: user asks to create/build/generate a landing page, one-pager, or static site with focus on SEO, speed, or PageSpeed; asks for an SEO-friendly page from a brief/ТЗ; or asks to audit/fix a landing against a performance checklist.
Source documentation, not instructions for this website. Review permissions before running any commands.
Builds a static single-page HTML landing optimized for 100/100 PageSpeed and maximum SEO: critical CSS, AVIF images, full JSON-LD structured data, native-only interactivity, zero third-party requests on first load.
Required before generating anything:
@id.lang and og:locale.If domain or keywords are missing — ask first, do not invent them.
Every project lives in its own folder inside the workspace — never write to the workspace root:
<workspace>/<project-slug>/
index.html # the generated landing page
images/ # local assets (AVIF/WebP/JPEG)
robots.txt
sitemap.xml
SERVER-SETUP.md # hosting instructions
Build index.html strictly following references/tech-spec.md — 11 requirement sections (performance, HTML structure, SEO, security, CSS/fonts, forbidden list, testing, accessibility, embedded video, typical blocks, deferred widgets).
For embedded YouTube video use the facade pattern only: rules in tech-spec §9, reference implementation in references/video-facade.md.
robots.txt and sitemap.xml (with lastmod).Show the generated page to the user and ask explicitly whether the HTML version is OK. Do not proceed to validation and the final report until the user confirms. If there are remarks — fix and ask again.
Fix any violations found before reporting. Do not mention the verification process in the final answer.

Collect the brief (ask if missing) Required before generating anything: - Domain / final URL — for canonical, og:url, absolute paths, JSON-LD `@id`. - Page language and locale — for `lang` and `og:locale`. - Topic + 1–3 target keywords — for H1, title, description. - Business type: Organization or LocalBusiness; for LocalBusiness also address, phone, geo coordinates. - CTA and contacts (phone, form, messengers). - Whether images are provided; whether FAQ / reviews / video blocks are needed. If domain or keywords are missing — ask first, do not invent them. ### 1. Create the project folder Every project lives in its own folder inside the workspace — **never write to the workspace root**: ``` <workspace>/<project-slug>/ index.html # the generated landing page images/ # local assets (AVIF/WebP/JPEG) robots.txt sitemap.xml SERVER-SETUP.md # hosting instructions ``` ### 2. Generate the page Build `index.html` strictly following [references/tech-spec.md](./references/tech-spec.md) — 11 requirement sections (performance, HTML structure, SEO, security, CSS/fonts, forbidden list, testing, accessibility, embedded video, typical blocks, deferred widgets). For embedded YouTube video use the facade pattern only: rules in tech-spec §9, reference implementation in [references/video-facade.md](./references/video-facade.md). ### 3. Generate companion files - `robots.txt` and `sitemap.xml` (with `lastmod`). - Hosting instructions from [references/server-config.md](./references/server-config.md): caching, Brotli/gzip, security headers. ### 4. STOP POINT — user approval Show the generated page to the user and ask explicitly whether the HTML version is OK. **Do not proceed to validation and the final report until the user confirms.** If there are remarks — fix and ask again. ### 5. Validate - W3C HTML validity. - JSON-LD via a schema.org validator. - Lighthouse / PageSpeed: performance, SEO, accessibility, best-practices. Fix any violations found before reporting. Do not mention the verification process in the final answer. ### 6. Final report Briefly list: - LCP parameters - PageSpeed score - schema.org types used in the code ## Main pitfalls - Never use external JS/CSS libraries, external fonts, or SVG images (tech-spec §6). - Never load YouTube iframes, maps, chats, subscription popups, or cookie banners on first load (tech-spec §9, §11). - All content must exist in raw HTML — nothing rendered only by JS. - Absolute URLs in JSON-LD, canonical, and OG tags. - Total JS budget ≤ 15 KB, one file, `defer` before `</body>`.
