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

- 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
The drawer aside was set to `bg-white/50 dark:bg-white/[0.01]` with a
`backdrop-blur-3xl`. In light mode this rendered as a 50%-transparent
white panel over the page underneath, which made every item read
"grayed-out" through the blur. In dark mode the 0.01 white was so
faint that the panel was effectively transparent.
Switch to `bg-sidebar` — the opaque sidebar token already used by the
desktop navbar — and drop the backdrop blur (pointless without the
transparency). Items now sit on a solid surface with normal contrast
in both themes.
## Label
"Talk to Our Engineers" → "Talk to an Engineer" everywhere it appears
(button text, aria-labels, mobile drawer entry, source comment).
## Desktop pill (≥1100px)
- Gradient fill (indigo-500/90 → purple-500/90 at rest, full at hover)
- Soft shadow lift on hover
- Shimmer animation: a translucent white stripe slides across via an
::after pseudo-element on hover (overflow-hidden + after:translate-x
transition over 700ms). Replaces the earlier scale-on-hover.
- Breakpoint lowered from 1400px → 1100px so the pill is visible at
most laptop widths where there's plenty of room
## Compact calendar icon (md → 1099px)
- New second button rendered alongside the pill, visible only when
the rest of the right cluster is icon-only (768–1099px)
- Same gradient + shimmer treatment in a 36×36 rounded-full button
- Inline calendar SVG (matches the Lucide calendar shape)
## Free Developer Access — shell-docs parity with docs/
- Added as a text link in shell-docs' LEFT_LINKS (mirrors the existing
docs/ pattern); cloud icon on the right cluster now hands off to it
at ≥1100px
- Visibility transitions on both surfaces realigned to 1100px so the
cloud↔text and calendar↔pill flips happen at the same boundary
- whitespace-nowrap on LEFT_LINKS label spans so long labels like
"Free Developer Access" don't wrap when the nav gets tight
## Mobile drawer
- docs/: add a Talk-to-Engineer button at the top of MobileSidebar
(was missing entirely). Tracks `talk_to_us_clicked` with
location: docs_navbar_mobile.
- shell-docs: move the existing Talk-to-Engineer button to the top of
the drawer column so it's the first thing readers see.
Updates the docs navbar and showcase shell-docs brand-nav so the "Talk
to engineers" CTA points at copilotkit.ai/talk-to-an-engineer instead
of the deprecated /contact-us endpoint.

Add a Learn-only sidebar mode that mirrors how /reference works: when a user
is under /learn, the framework picker is hidden and the sidebar shows only
learn content (What's New, Agentic Protocols, Generative UI, Specs,
Architecture, Tutorials).
- Add `learn` to the root meta.json so the learn folder is discoverable in
the page tree (was missing, which is why ConditionalSidebar previously
fell through to the default sidebar on /learn routes)
- Add a static LearnHeader (book icon + "Learn") visually matching the
Reference version selector, wired in via Sidebar's headerSlot
- Rename the learn index page title to "Overview" so the landing page reads
cleanly under the new header
- Drop the redundant `h-6` spacer in Sidebar — every header component
(IntegrationSelector, VersionSelector, LearnHeader) already supplies its
own `mb-3`, and the spacer was producing a 24px phantom gap on /learn
while collapsing to 0 on /reference under flex shrink

Renames the docs CTA tracking event from `cta_clicked` to
`try_for_free_clicked` to match the per-event custom event names used
on the marketing website, and uses a single `location` string property
in place of the previous `surface` / `variant` / `target` / `page_path`
shape. Surface identifiers are normalized to underscored snake_case to
match the location values already used on the website.
Same change applies to the docs navbar handler that fires when a
visitor clicks the Free Developer Access link.
Introduces a reusable OpsPlatformCTA component with four visual variants
(card, info, inline, tile) for placing dashboard sign-up calls-to-action
across the docs. Each click captures a `cta_clicked` PostHog event tagged
with surface, variant, and page path, and navigates to the dashboard with
UTM parameters identifying the source surface.
Registers the component in both MDX provider maps (home and integrations
slug routes) so it can be used in any MDX file.
Repoints the navbar "Free Developer Access" link to the dashboard and
wires the same PostHog tracking to its left and right placements.
Adds a CTA button to the right side of the docs navbar mirroring the
website's nav button, including matching PostHog instrumentation. Fires
talk_to_us_clicked with { location: "docs_nav" } so docs-originated
clicks can be segmented separately from website clicks (which use
"nav"). Visible at viewports >= 1400px to avoid forcing the left
links to wrap; hidden below that breakpoint where the mobile burger
menu surfaces the link instead. Styled with text-muted-foreground to
match the existing nav links and an indigo #7076D5 hover accent that
matches the active-link underline.
The slanted SVG borders bridging the navbar's left and right pill
containers were sized with fixed pixels (w-[24px] h-[60px] /
xl:w-[29px] xl:h-[72px]). When users scale Chrome's default font size
above 16px, rem-based content inside the nav grows but the SVGs stay
fixed, leaving a visible wedge of page background at the top of the
join. Switch to h-full w-auto so the SVGs follow the container's
actual height while preserving their viewBox aspect ratio.
Update user-facing references from "LangGraph" to "LangChain" per CPK-7186.
The integration label, descriptions, and agent terminology now use "LangChain"
while preserving "LangGraph" for technical references (Platform, Studio, CLI,
StateGraph, code/package names, and API references).
- Rename integration label in integrations.ts, meta.json, integration-grid,
feature-matrix, quickstart-dropdown, and link-validation
- Update ~47 MDX docs: "LangGraph agent(s)" → "LangChain agent(s)"
- Update FAQ, snippets, and learn section references
- Keep URL paths (/langgraph) unchanged for backward compatibility
- Keep all code imports, package names, and LangGraph Platform/Studio/CLI as-is
