N/A - Internal initiative for Answer Engine Optimization (AEO)

Description

Adds Answer Engine Optimization (AEO) support to the marketing site at apps/web-roo-code:

1. llms.txt and llms-full.txt (served from public/)

• llms.txt -- Concise, LLM-readable summary (~40 lines) following the llms.txt spec. Includes product descriptions, key links, and quick facts.
• llms-full.txt -- Comprehensive markdown (~250 lines) covering the full product surface: Extension capabilities, Cloud agents, integrations (Slack, Linear, GitHub), pricing tiers, security/compliance, getting started, community links, and FAQ.
• Both files are served automatically at roocode.com/llms.txt and roocode.com/llms-full.txt.

2. /what-is-roo-code page

A content-rich informational page targeting answer-engine queries like "what is roo code", "AI coding agent", etc.:

• Full SEO metadata (title, description, canonical, OG, Twitter, keywords)
• AboutPage + Article JSON-LD structured data with speakable specification
• Product overview, key capabilities (6 cards), role-specific modes, model-agnostic design
• Cloud Agents vs VS Code Extension comparison (Cloud prioritized first)
• "Why developers choose Roo Code" differentiators (6 cards)
• Getting started steps
• Reuses existing FAQSection and CTASection components

3. Navigation updates

• Added "What is Roo Code?" link to Resources dropdown (desktop + mobile) in nav-bar.tsx
• Added "What is Roo Code?" link to Resources column in footer.tsx
• Updated next-sitemap.config.cjs with priority 0.9 for the new page

Test Procedure

• Verify llms.txt and llms-full.txt are accessible at their respective URLs after deploy
• Verify /what-is-roo-code renders correctly with all sections
• Verify navigation links appear in desktop dropdown, mobile menu, and footer
• Verify JSON-LD structured data renders in page source
• Run npx tsc --noEmit in apps/web-roo-code -- passes clean
• ESLint passes with 0 warnings

Pre-Submission Checklist

Rooviewer   See task

Found 1 issue (2 instances) -- both Button components in the new page are missing the asChild prop, causing invalid HTML nesting.

• Add asChild to the Cloud CTA Button wrapping <a> (line 396)
• Add asChild to the Extension CTA Button wrapping <a> (line 448)

This Button wraps an <a> without the asChild prop, so it renders as <button><a>...</a></button> -- invalid HTML (interactive content nested inside <button>). Clicking the button padding outside the link text won't navigate. The rest of the codebase uses asChild for this pattern (e.g. slack/page.tsx, pricing/page.tsx, cloud/page.tsx).

Suggested change

	<Button
	size="lg"
	className="w-full sm:w-auto bg-violet-600 hover:bg-violet-700 text-white">
	<a
	href={EXTERNAL_LINKS.CLOUD_APP_SIGNUP_HOME}
	className="flex items-center justify-center gap-2">
	Try Cloud for Free
	<ArrowRight className="size-4" />
	</a>
	</Button>
	<Button
	size="lg"
	className="w-full sm:w-auto bg-violet-600 hover:bg-violet-700 text-white"

Same issue here: missing asChild means this renders <button><a>...</a></button>, which is invalid HTML nesting. Clicks on the button area outside the link text won't navigate to the marketplace URL.

Suggested change

	<Button size="lg" className="w-full sm:w-auto">
	<a
	href={EXTERNAL_LINKS.MARKETPLACE}
	target="_blank"
	rel="noopener noreferrer"
	className="flex items-center justify-center gap-2">
	<Download className="size-4" />
	Install Free Extension
	</a>
	</Button>
	<Button size="lg" className="w-full sm:w-auto" asChild>
	<a
	href={EXTERNAL_LINKS.MARKETPLACE}
	target="_blank"
	rel="noopener noreferrer"
	className="flex items-center justify-center gap-2">
	<Download className="size-4" />
	Install Free Extension
	</a>
	</Button>
