SaaS Landing Skill

Produce a single-page SaaS landing. Agent, follow this workflow exactly.

1. Read context

Before writing anything:

• Read DESIGN.md in the current working directory. If missing, stop and ask for one.
• Identify the color palette, typography tokens, and layout principles.
• Note the "Agent Prompt Guide" section — it overrides any instruction here if they conflict.

2. Plan sections

Required sections, in order:

1. Hero — logo-or-wordmark, headline (tagline input), subhead (1–2 sentences), primary CTA, secondary CTA. Use the hero_density parameter as vertical padding in px.
2. Features — 3–6 feature tiles. Each: icon, short title, 1–2 sentence body.
3. Social proof — proof_count logos or testimonials. If 0, skip this section.
4. Pricing — 2–3 tiers. Include only if has_pricing is true.
5. Footer CTA — large accent-colored band with one-button call to action.
6. Footer — minimal: links + copyright.

3. Apply design system

• All colors must come from DESIGN.md tokens. Do not invent hex values.
• Typography: use the declared display font for headlines, body font for everything else.
• Layout: respect the grid, max-width, and section spacing rules.
• Components: use declared button/card/input patterns. Do not add shadows if DESIGN.md's Depth & Elevation says minimal.
• Accent: use the accent color only once in the hero, once in the footer CTA, and for all links. Do not flood the page.

4. Write the file

Output a single self-contained index.html with:

• All CSS inlined in a <style> block in <head>.
• System font fallbacks if DESIGN.md fonts aren't loadable from Google Fonts etc.
• No external JS.
• Semantic HTML (<header>, <main>, <section>, <footer>).
• Each editable element tagged with data-od-id="<unique-slug>" so the host app's comment mode can target it.

5. Self-check

Before finishing, verify:

• All text is content-meaningful, not lorem ipsum (use product_name and tagline inputs; generate plausible specific copy for the rest).
• No broken color references (every CSS color value is in DESIGN.md's palette or a valid alpha/fallback variant).
• Responsive breakpoints match DESIGN.md's Responsive Behavior section.
• The page looks good at 1440w, 768w, and 375w (mentally simulate).
• Accent used no more than twice total.

6. Done

Write only index.html. Do not generate a separate CSS file, JS file, or README.

For skill authors reading this as a reference

This is a minimal but complete skill. Structure:

saas-landing-skill/
├── SKILL.md    ← you are here
└── assets/
    └── base.html    (optional starter template; this skill doesn't use one)

Things to notice:

• The od: front-matter block is optional for Claude-Code-only compatibility, but adding it lights up OD's typed inputs, sliders, preview metadata, and capability gating.
• The workflow below the front-matter is plain Markdown that the agent reads as its system prompt.
• DESIGN.md is treated as a collaborator, not an override. The skill gives the agent authority to override when the brief conflicts, but never to invent new tokens.
• data-od-id tagging is how we wire elements to comment mode. Skills that want comment-mode compatibility must annotate their output.

See ../../docs/skills-protocol.md for the full protocol.
