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.**

The initial shell-docs content-import left 21 reference pages with missing
import statements: 8 component pages had empty `## Import` code fences, and
13 hook pages had `## Signature` fences whose leading `import { X } from
"@copilotkit/react-core/v2";` line was stripped.
This commit restores the import(s) in the Import and Signature fences only.
Usage examples and other code blocks are intentionally not touched.
- 8 components: fill empty Import fence with named (or default for
CopilotChatView) import + styles.css side-effect import
- 13 hooks: prepend import line(s) at the top of the Signature fence.
- useComponent: 3 imports (z, type ComponentType, useComponent)
- useRenderTool: imports injected into both Wildcard and Named overload fences
- useCopilotChatConfiguration: imports injected into both Provider and
hook ### Signature subblocks
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
Two pre-existing type errors from commit 9b05ed41 surfaced on main's
Docker build:
1. `unscoped-docs-page.tsx` imports `findFrameworksWithCell` from
`@/lib/docs-render`, but the helper was only declared locally in the
two page.tsx routes with a 1-arg signature (and referenced an
undeclared `demos` in one case — dead code). Export a 3-arg shared
version from docs-render.tsx that accepts the integration slug list
and demo map as parameters (keeps the lib free of registry imports),
drop the dead local in `[[...slug]]/page.tsx`, and rewire the live
caller in `[framework]/[[...slug]]/page.tsx` through the shared
export.
2. The Step-2 section cards on the overview call `<SidebarLink>`
without the required `scope` prop. The prop was already ignored
internally (destructured as `_scope`) so relaxing it to optional is
the minimal fix and keeps the call-site intent documented.
`npm run build` in showcase/shell-docs now compiles cleanly.
Drop error-boundary-card in favour of Next.js error.tsx at each route,
refresh docs components (brand-nav, docs-callout, docs-page-view,
docs-steps, docs-tabs, framework-provider/selector/tabs,
property-reference, router-pivot, sidebar-link, snippet), update
docs-render + mdx-registry + reference-items for the new QA shape.
The scrub and #4084 touched the same surface: #4084 re-added an `open:`
generative_ui profile listing `open-gen-ui`/`open-gen-ui-advanced`, and
re-added both features to `constrained-explicit.allowed`. Extending the
branch's scrub to both re-additions keeps the semantic consistent with
the schema (which already dropped `open` from the approaches enum).
- `showcase/shared/constraints.yaml`: drop `open-gen-ui` +
`open-gen-ui-advanced` from `constrained-explicit.allowed`; drop main's
re-added `open:` profile entirely.
- `showcase/packages/langgraph-python/manifest.yaml`: drop the now-orphan
`open-gen-ui` + `open-gen-ui-advanced` feature and demo entries
(validator confirmed they had no allowed approach left).
- Regenerated `showcase/shell/src/data/registry.json` + sibling
`shell-docs`/`shell-dojo` registries and `constraints.json` via
`pnpm --dir showcase/scripts generate-registry`. All 17 integrations
validate.
`feature-registry.json` intentionally still defines both features — the
original scrub commits (2b996c54d, 27f886e59) left it untouched, so the
demo source files on disk also stay. Follow-up deletion if desired is
out of scope for this merge.
There is no app/integrations/ route, so the reservation was causing
/integrations/... URLs to 404. Without it, these paths fall through to
UnscopedDocsPage via the non-integration fallthrough in [framework].
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.
buildNavTree now checks meta.root before including a subdirectory,
so unselected/ (and any other root:true directory) is excluded from
the main nav tree. This eliminates the flicker where SidebarLink
generated /langgraph-python/unselected/coding-agents and the
[framework] route had to server-redirect to the correct scoped URL.
On framework-scoped pages, MDX links like /quickstart rendered as plain
<a href="/quickstart"> causing RouterPivot redirect flicker. Override the
MDX `a` component when frameworkOverride is set to prepend the framework
prefix to root-relative internal links.
Next.js routes /quickstart to [framework]/[[...slug]] (dynamic segment
beats optional catch-all), where "quickstart" is not a registered
integration, causing notFound(). Fix by:
- Extracting the unscoped doc rendering logic into UnscopedDocsPage
- Falling through to it in [framework] when the slug is not a framework
- Simplifying [[...slug]]/page.tsx to handle only the root overview
SidebarLink now uses storedFramework as fallback so links on the
overview page go directly to /<framework>/<slug> without a RouterPivot
redirect. OverviewNavItem and section cards now use SidebarLink for the
same reason. FrameworkSelector "Clear selection" was navigating to
/docs/<slug> (broken); fixed to /<slug>. hrefFor now preserves the
current slug when switching frameworks from an unscoped page.
SidebarLink fallback, framework-scoped backLink, "framework-agnostic
version" banner link, FrameworkLandingPage sidebar, and brand-nav
all still pointed at /docs/* which routes to 404 via the [framework]
catch-all. Switch all to / or /<slug>.
Override InlineDemo in DocsPageView's MDX component map to substitute
defaultFramework for the hardcoded integration prop when a framework
is selected. MDX files don't need to change — the override happens at
the render layer, matching how Snippet already handles this.
DOCS_SECTIONS, OverviewNavItem, CopilotKit Docs link, backLink, and
slugHrefPrefix all generated /docs/<slug> paths that 404 — the
[framework] catch-all intercepted "docs" as a framework slug and
returned notFound(). Strip the /docs prefix so all root-route links
resolve correctly.
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/error-debugging.mdx
troubleshooting/migrate-to-1.10.X.mdx

## Internal link fixes — /unselected/ removed (×2 files)

## Summary
- **shell-dashboard:** dashboard.showcase.copilotkit.ai rendered every
"demo" and "code" link as `http://localhost:3000/...`. Root cause:
`NEXT_PUBLIC_SHELL_URL` was never provided at build time and the source
fell back to `localhost:3000`. Next.js inlines `NEXT_PUBLIC_*` at `next
build`, so a runtime Railway env var could not rescue a bad build. Fix
plumbs the value through as a Docker build arg from
`showcase_deploy.yml` and fails loudly at build if it's unset so this
can't regress silently.
- **shell-dojo:** dojo.showcase.copilotkit.ai was missing items in the
langgraph column (langgraph-python showed 9 demos vs 20+ in the
manifests). Root cause: `shell-dojo/src/data/registry.json` was stale —
the generator only wrote to `shell/`, the dojo Dockerfile never ran the
generator at build, and the CI path filter didn't rebuild the dojo when
manifests changed. Fix dual-emits from `generate-registry.ts` to
`shell/`, `shell-dojo/`, and `shell-docs/`, runs the generator in the
dojo Dockerfile, expands the workflow's path filter to include
`packages/**` and `shared/**`, and refreshes the committed JSON so it
matches what the generator produces today. Langgraph-python demo count 9
→ 32.
## Test plan
- [x] `shell-dashboard` Docker build succeeds with
`NEXT_PUBLIC_SHELL_URL` build arg (Depot `36wlvzkgp1`).
- [x] `shell-dashboard` Docker build fails loudly when the build arg is
omitted (Depot `mbh41c3qtk`).
- [x] `shell-dojo` Docker build succeeds; generator+bundler run at
build; 159 demos bundled (Depot `h7bbq8f8jt`).
- [x] `showcase_deploy.yml` passes YAML validation.
- [ ] After merge + deploy: verify `dashboard.showcase.copilotkit.ai`
links point to `https://showcase.copilotkit.ai/...`.
- [ ] After merge + deploy: verify `dojo.showcase.copilotkit.ai` shows
the full langgraph column (langgraph-python ≥ 20 items).
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 dojo app was missing items under the langgraph column because
shell-dojo shipped a stale committed registry.json. The generator
only wrote to shell/, the dojo Dockerfile didn't run the generator
at build, and the CI path filter didn't rebuild the dojo when
manifest files changed.
Fix: emit from generate-registry.ts to shell, shell-dojo, and
shell-docs; add the generator step to shell-dojo's Dockerfile;
expand the deploy workflow's path filter to include packages/**
and shared/**; and refresh the committed registry/demo-content
JSON so files on disk match what the generator produces today.
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>`
Directory-plus-index.mdx layout produced two reference entries for
the same logical page: one at `foo/` (the index) and one at `foo`
(a flat sibling if it existed). Collapse index.mdx into the parent
slug so the generated list has a single canonical entry, and bail
out with a clear error when a flat-file collision would shadow the
index. Prevents silently dropping one of the two pages at build
time.
The log effect depended on the error object identity, which changes
on every render even when the underlying error is the same — so the
effect fired repeatedly and spammed the log. Depend on
error.message and error.digest (primitive, stable across renders
of the same error) instead. React's exhaustive-deps check is still
satisfied because those are the fields the effect actually reads.
