Page Build

Build quality comes after strategic fidelity, not before it.

This stage assembles the page while preserving what matters for trust and conversion.

Required inputs

1. workspace/pages/[page-name]/strategy.json
2. workspace/brand/profile.md
3. workspace/brand/palette.json
4. workspace/pages/[page-name]/copy.md
5. workspace/pages/[page-name]/visuals/
6. references/anti-slop.md (bundled with this skill)

If strategy is missing, stop.

If workspace/pages/[page-name]/visuals/manifest.json exists, use it as the canonical machine-readable visual source. Do not ignore provider metadata when it affects trust, fidelity, or fallback history.

Preservation hierarchy

Apply in this order:

1. preserve trust-critical category conventions
2. preserve mechanism communication needs
3. preserve brand visual identity
4. improve layout rhythm and interaction quality
5. apply anti-slop taste improvements only where they do not distort 1-4

Anti-slop is a quality filter, not a redesign license.

Pre-build checklist

Before generating HTML, confirm:

• page type confirmed
• conversion mechanism confirmed
• proof inventory loaded
• trust cues selected
• visual manifest resolved into build-ready image paths
• required category conventions preserved
• CTA destination known
• layout choice justified in one line

If any are false, stop or downgrade.

Routing logic

Physical product route

Use when strategy page type is product-led.

Above fold must include:

• clear product or mechanism visual
• offer headline
• CTA
• trust cue

SaaS / app route

Above fold must include:

• preserved screenshot or UI treatment if required
• outcome headline
• trust cue
• CTA

Lead capture route

Above fold must include either:

• form + friction reducer

or

• clear CTA into a known destination

Authority / service route

Must include:

• authority cue above fold
• proof section early
• objection handling around trust and fit

Regulated route

Must include:

• downgraded certainty when proof is partial
• compliance review flag in metadata

Design rules

• single HTML file
• responsive at minimum 768px and 1024px breakpoints
• semantic HTML
• visible focus states
• alt text on all images
• no builder attribution unless explicitly requested
• no imported taste pattern that overrides source trust cues

Anti-slop usage

Load references/anti-slop.md and apply it after the preservation hierarchy, not before.

Post-build QA table

Write this into workspace/pages/[page-name]/qa.md and summarize in meta.json:

Metadata contract

meta.json must include:

• brand
• page
• page_type
• mechanism_type
• template_route
• CTA_destination
• proof_items with provenance summary
• riskreversalpresent
• compliance_flags
• review_flags
• preserved_elements
• deviationsfromsource
• images_used
• sections_present
• build_confidence

When a visual manifest exists, also include:

• hero_image
• imageproviderpolicy
• images_used as structured objects, not only bare filenames
• provider and fallback context when relevant to review or QA

Build helper

Use scripts/resolve-visual-assets.py --page-name [page-name] to convert visuals/manifest.json into build-ready image metadata for HTML and meta.json.

Then use scripts/prepare-build-meta.py --page-name [page-name] --resolved-assets [file] to merge those resolved assets into meta.json with deterministic selection fields:

• hero_image
• mechanism_image
• lifestyle_image
• og_image
• image_slots.hero
• image_slots.mechanism
• image_slots.lifestyle
• image_slots.og

Then use skills/page-build/scripts/html-image-context.py --meta workspace/pages/[page-name]/meta.json to emit literal HTML-ready values such as:

• heroimgsrc
• heroimgalt
• mechanismimgsrc
• mechanismimgalt
• lifestyleimgsrc
• lifestyleimgalt
• ogimagepath

Minimal executable builder:

• skills/page-build/scripts/build-page.py --page-name [page-name]

This consumes strategy.json, meta.json, and html-image-context.json and writes a real index.html scaffold.

Use the skill-local scripts as the primary interface for Cowork or any agent runtime that only uploads the skill folder. The repo-root /scripts copies are local development conveniences, not a packaging requirement.

Eval Reference

For scoring criteria and pass thresholds, see skills/page-qa/references/eval-rubric.md. For anti-slop patterns, see references/anti-slop.md (bundled with this skill).

Stop / continue logic

Stop if:

• CTA destination is unknown for a lead action page
• page depends on proof that is missing
• required trust cues cannot be supported

Continue with downgrade if:

• visual assets are partial but neutral support layout still works
• proof is light but the page is reframed to softer claims

Output

Write:

• workspace/pages/[page-name]/index.html
• workspace/pages/[page-name]/meta.json
• workspace/pages/[page-name]/qa.md

A build without QA output is incomplete.
