Refreshes the shell docs chrome around the shared theme tokens, announcement banner, desktop and mobile navigation, search trigger, theme toggle, and sidebar footer actions.
Call-site enumeration:
- PrimaryDocsTabs: rendered by MobileTopNav for tablet header tabs and ShellDocsLayout for mobile sidebar tabs.
- MobileSidebarFooterTalk: rendered by ShellDocsLayout sidebar.footer and hidden outside mobile/tablet sidebar usage via responsive classes.
- INTELLIGENCE_CTA_HREF and TALK_TO_ENGINEER_HREF: exported from BrandNav and reused by BrandNav/MobileSidebarFooterTalk so CTA destinations stay centralized.
Stack upgrade
- fumadocs-core/ui 15.8.5 → 16.8.12, next 15 → 16 (Turbopack), react 19 → 19.2
- Swap "next lint" → "oxlint ." to match the rest of the repo
- New deps for the page-actions component: @radix-ui/react-popover,
class-variance-authority, clsx, tailwind-merge
Layout & brand polish
- Sidebar floats as a rounded-2xl card with column-aligned padding;
framework picker pill, accent-purple section icons (16px), accent
active state, and a single divider line at the footer
- New custom <ThemeSwitch> — single 50×28 neutral switch replaces the
fumadocs sun/moon split (drops the vertical divider and purple tint)
- Sidebar folder collapse state persists across navigations via
SidebarFolderStatePreserver
- BrandNav: wider top bar, lowercase "Talk to an engineer", BookIcon
for Docs, GitHub/Discord icons rendered inline in our footer row
- Mobile: nav clipping + content padding fixes, content grid-span-full
- TOC-less pages: lift article max-width so content stretches into the
empty TOC column on wide viewports
New routes
- /llms.txt — page index per fumadocs LLMs integration
- /llms-full.txt — concatenated full text of every docs page
- /<path>.md and /<path>.mdx — per-page raw markdown with <Snippet>
regions inlined as fenced code blocks (resolver in lib/llm-text.ts
reuses the same demo-content.json the <Snippet> runtime reads)
- Page-actions bar: Copy Markdown + Open in Claude / Claude Code /
Windsurf / Codex (Codex links to https://chatgpt.com/codex for
universal coverage)
Content fixes
- Reasoning page (generative-ui/reasoning.mdx): rewrite to point at
the real reasoning-default / reasoning-custom cells instead of the
stale agentic-chat-reasoning / reasoning-default-render names
- Strip <FeatureIntegrations /> chip list ("SUPPORTED BY ...") from
16 docs MDX files (component definition kept in mdx-registry)
- Drop hideTOC: true from 11 pages so they pick up the lifted-cap rule
- Default home (/) to the built-in-agent authored sidebar; fix active
state matching on the home url
- Restore default fumadocs Callout (drop the bespoke docs-callout)
- OpsPlatformCTA redesign — light bordered card with accent stripe
- FrameworkOverview redesign — drop atmospheric chrome, smaller hero
- Homepage / docs-landing redesign
Integrations (LGP / LGT / ADK)
- Tag @region[default-reasoning-zero-config] in reasoning-default and
@region[reasoning-block-render] in reasoning-custom for all three
frameworks so the docs <Snippet> calls resolve
- Tag @region[use-agent-simple] + @region[message-list-simple] in
headless-simple and @region[use-rendered-messages-hook] +
@region[manual-tool-call-rendering] +
@region[manual-activity-message-rendering] + @region[custom-bubbles]
across headless-complete
Other
- docs/components/layout/mobile-sidebar.tsx: lowercase "engineer" to
match shell-docs
- .claude/launch.json + .claude/preview/ — dev launch configs for the
worktree so /preview brings up shell-docs on :3003
Rebuild the shell-docs chrome on top of Fumadocs UI primitives and ship the
visual polish pass that replaces the legacy custom chrome.
- Fumadocs adoption: route every docs page (home, framework-scoped, ag-ui)
through a shared ShellDocsLayout that wraps DocsLayout / DocsPage with
the project's nav slot, sidebar config, scroll preserver, and content
wrapper. Swap custom tabs/code-block components for Fumadocs's Tabs,
CodeBlock, Pre, CodeBlockTabs, DynamicCodeBlock — Snippet and DemoSource
now share the same chrome as authored fenced blocks.
- Syntax highlighting: replace rehype-highlight + hand-rolled hljs CSS
with Fumadocs's Shiki-based rehypeCode in all three MDX renderers and
in mdx-registry-loader. A tiny `transformerMeta` Shiki transformer
surfaces fence title= / language as data-attrs so MdxCodeBlock can
render the file-path figcaption + floating copy button.
- Sidebar: floats on all four viewport edges (rounded-2xl, 0.75rem inset,
light-gray border), framework picker pill is rounded-xl with symmetric
padding above/below, sticky picker bg matches the panel surface.
Section headers render in normal caps (no more uppercase shouting), with
scroll position preserved across navigations via SidebarScrollPreserver.
- Navbar: bg flips to `--bg`, full-width inset matches the sidebar,
search trigger drops its border and the entire right-wing pill is the
click target.
- Code chrome: figure surface forced to plain white in light and the
matching dark in dark, shadow stripped, figcaption divider uses
`--border` (was `currentColor` from `text-fd-muted-foreground`). Scoped
the `.reference-content code` chip-bg rule to `:not(pre)` so block
code bodies no longer pick up the gray inline-chip background.
- Content area: 49px (3.0625rem) of left/right padding so the article
column has visible breathing room from both the floating sidebar and
the viewport edge.
- IA: meta.json restructure for /docs (Build Generative UI section,
controlled/declarative/open-ended folders, A2UI lifted to its own
folder with an index page, Migrate moved under Other), Concepts content
rewrite, snippet/region cleanups.
