Resolves former priority item 5. The Styling sections on the chat, sidebar,
and popup prebuilt-component pages (base + unselected/) each had an inline
tsx code fence that duplicated styling patterns already covered on the
dedicated /custom-look-and-feel/{css,slots,headless-ui} pages. Per Atai's
directive that every code fence in shell-docs should be a showcase-linked
Snippet, not hand-written, removing these fences is the right move here.
Section headers, intro copy, and bullet links to the dedicated styling
pages are preserved — those are legitimate pointers.
Adds multimodal-attachments, runtime-server-adapter, and vs-code-extension
pages under a new ---Platform--- section in meta.json. threads.mdx was
already in place and left untouched. fumadocs-ui import lines are stripped
since shell-docs pulls components from its MDX registry instead.
When the runtime registers an agent as default, CopilotKit hooks auto-select
it; passing agentId: "default" (or a stale "assistant" ID that isn't
actually registered) is noise. Applies to built-in-agent/shared-state.mdx
and unselected/shared-state.mdx across shell-docs and upstream.
Goal: fast 'wow that's fast' initial experience for users trying the
built-in agent. Sweeps shell-docs unselected/ and upstream built-in-agent/
so both trees match. Also collapses two mismatched GPT-4o rows in the
model-selection table into a single honest 'GPT-5.4 Mini' row.
LangChain wants to be referred to as LangChain in docs; LangGraph is the
under-the-hood graph framework. Updates prose only — URLs, package names,
code identifiers, and LangGraph Studio/Platform product names are preserved.
Upstream docs/ already reflects this change; this brings shell-docs into
alignment so the next sync does not regress.
⚠️ **Docs sync — MANUAL REVIEW REQUIRED**
This PR was auto-opened because the docs-sync script detected
showcase-local modifications overlapping with upstream changes.
The script attempted a best-effort 3-way merge:
- Where `git merge-file` produced a clean merge, the merged content was
written.
- Where `git merge-file` produced conflict markers, **upstream content
was written as-is** and showcase-local modifications were overridden.
**Manual review required.**
### Review items

Replace em-dashes in prose across ~37 shell-docs files with appropriate
punctuation (colons, semicolons, commas, parens, periods). Also fixes a
hardcoded "LangGraph Python" reference in quickstart.mdx bridging text,
adds a user-friendly placeholder when no framework is selected on snippet
pages, and makes heading code font size proportional rather than fixed.
- Update registry.json, demo-content.json, status.json, constraints.json,
docs-status.json across shell/shell-docs/shell-dojo
- Add integration="langgraph-python" default to quickstart InlineDemo so
the base unscoped page shows a demo instead of being empty
- Replace FeatureMatrix stub with a real server-rendered table reading from
registry — 17 integrations × 12 curated feature columns, sticky first column,
✓/— cells, integration names link to /{slug} landing pages
- Fix matrix links from /integrations/{slug} (404) to /{slug}
- Remove redundant "Feature comparison" section from index.mdx (FeatureMatrix
was a stub pointing to same destination as IntegrationGrid)
- Add .reference-content .not-prose a rule to suppress underlines on card grids
inside MDX without breaking prose link styling
- Add intro sentence to "Explore by AI backend" section
- Correct 3 mismatched feature IDs in MDX (generative-ui-tool-based ->
gen-ui-tool-based, frontend-tools-sync -> frontend-tools, reasoning ->
agentic-chat-reasoning) so FeatureIntegrations renders integration chips
- Remove stale 'matrix' from RESERVED_ROUTE_SLUGS (no app/matrix/ route exists)
- Replace broken /matrix links in IntegrationGrid and search-modal with /
since the matrix lives in shell-dashboard, not shell-docs
Strip snippet_framework: langgraph-python from frontmatter and
integration="langgraph-python" from all InlineDemo tags in the
main docs tree (27 files). On framework-scoped pages frameworkOverride
drives Snippet and InlineDemo; on unscoped pages FrameworkGuardedContent
already hides the body until a framework is selected, so no default
is needed.
Page-by-page audit of showcase/shell-docs MDX content. All changes are
in src/content/docs/.
## Broken snippet region fixed
- generative-ui/a2ui/dynamic-schema.mdx: Step 5 referenced
`runtime-inject-tool` which does not exist in the declarative-gen-ui
cell. Replaced with a hardcoded code block showing `injectA2UITool: true`
(same content already shown on the parent a2ui.mdx page).
## MDX syntax fix
- frontend-actions.mdx: stray closing ``` at end of file (would cause
a parse/render failure).
## Internal link fixes — /docs/ prefix removed (×14 files)
The docs app routing does not use a /docs/ prefix — pages live at
/<slug>. Links using /docs/<slug> hit the reserved-slug guard in the
[framework] route and 404. Fixed across:
generative-ui/index.mdx (7 links)
generative-ui/tool-based.mdx (3 links)
learn/index.mdx (6 links)
multi-agent/subagents.mdx (2 links)
shared-state.mdx (2 links)
shared-state/streaming.mdx (2 links)
shared-state/agent-readonly.mdx (4 links)
troubleshooting/debug-mode.mdx
troubleshooting/error-debugging.mdx
troubleshooting/migrate-to-1.10.X.mdx
troubleshooting/migrate-to-1.8.2.mdx (2 links)
troubleshooting/observability-connectors.mdx
## Internal link fixes — /unselected/ removed (×2 files)
backend/copilot-runtime.mdx
backend/custom-agent.mdx
Drops the inline TypeScript typecast from the Mastra agent-app-context
example and uses optional chaining + direct access instead, so the doc
snippet is easier to read and copy. Keeps optional chaining on `.find`
so the example stays safe when the AG-UI context is absent. Also fixes
the `[!code highlight:N]` count after the comment line was removed.
Ports @Abubakar-01's changes from #4125 so they can ship together with
the `requestContext` rename, targeting the new `showcase/shell-docs/`
path after the shell restructure on main.

The upstream docs sync added 24 new integration pages (`threads.mdx`,
`premium/self-hosting.mdx`) plus learn/reference content, but didn't
land the runtime wiring they depend on — so the pages would ship blank.
It also accepted upstream changes in tool-rendering.mdx over local
modifications that needed to be restored.
- Register `Threads` / `SelfHosting` in SNIPPET_MAP so the shared
`<Threads />` and `<SelfHosting />` tags inline on integration pages
- Register `ThreadsEarlyAccess` wrapper + `MessageSquareMore` /
`Network` / `Newspaper` icons in mdx-registry for the new threads
content and the rebuilt `learn/index` card grid
- Revert tool-rendering.mdx upstream-wins regressions: framework-neutral
`/unselected/server-tools` link and `components={props.components}`
forwarding for the `<SharedContent>` override pathway
- Add `threads` + `...premium` to every integration's root meta.json
plus 11 new `premium/meta.json` files so the new pages appear in the
sidebar; update `docs/meta.json`, `docs/learn/meta.json`, and
`docs/premium/meta.json` the same way
- Fix `convertMarkdownTableToHtml` to emit JSX-valid tags. It was
generating `style="..."` string attributes, which next-mdx-remote
rejects; this path was dormant until the new threads page put a
markdown table inside a `<Step>`
These files were added in #4085 but landed in showcase/shell/src/content/docs/
after the MDX-docs extraction had already moved the rest of content/docs into
shell-docs. Follow The Rule (MDX docs content belongs in shell-docs) and
relocate them so they render correctly on docs.showcase.copilotkit.ai.
Extracts everything that exists to render MDX documentation (docs/[[...slug]],
[framework]/[[...slug]], ag-ui/[[...slug]], reference/[...slug]) out of shell
into the new shell-docs package that will serve docs.showcase.copilotkit.ai.
Moves (git mv preserves history):
- App routes: /docs, /[framework], /ag-ui, /reference
- Docs-only components: docs-page-view, docs-callout, docs-steps, docs-tabs,
mdx-components, framework-tabs, framework-selector, sidebar-*, snippet,
property-reference, router-pivot, stored-framework-highlight, react/*
- Docs-only libs: lib/docs-render, lib/mdx-registry
- All content: content/docs, content/ag-ui, content/reference, content/snippets
- .docs-sync-sha marker (follows the content)
Duplicates into shell-docs (both shells need them):
- brand-nav, search-modal, search-trigger, copy-button, framework-provider
- lib/registry.ts, data/registry.json, data/demo-content.json,
data/search-index.json
- app/layout.tsx + globals.css + public/{images,logos}
shell-docs gets its own minimal middleware (PostHog-only — no SEO redirect
table, docs host never served legacy URLs). shell keeps seo-redirects.ts
for the legacy-URL migration table; framework-scope protection in its
middleware is now effectively dead but harmless (next.config.ts redirects
fire before middleware ever sees /<framework>/ paths).
InlineDemo updated for cross-host context: 'Open full demo' link points
at the shell host (showcase.copilotkit.ai) since the integration profile
route only exists there.
