SaaS Landing Skill
Produce a single-page SaaS landing. Agent, follow this workflow exactly.
1. Read context
Before writing anything:
- Read
DESIGN.mdin 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:
- 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.
- Features — 3–6 feature tiles. Each: icon, short title, 1–2 sentence body.
- Social proof —
proof_countlogos or testimonials. If 0, skip this section. - Pricing — 2–3 tiers. Include only if
has_pricingis true. - Footer CTA — large accent-colored band with one-button call to action.
- 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-idtagging is how we wire elements to comment mode. Skills that want comment-mode compatibility must annotate their output.
