* Upgrade Kotlin docs to adk-kotlin 0.9.0 and move off AdkWebServer
adk-kotlin 0.9.0 split the web server into AdkApiServer, which serves the agent
runtime contract headlessly, and AdkDevServer, which adds the development UI.
AdkWebServer is deprecated in that release and goes away at 1.0, so WebMain.kt
as written here stops compiling the day 1.0 ships.
The quickstart snippet now builds an AdkDevServer from an AdkServerConfig. That
drops three imports: AdkServerConfig.inMemory() supplies the agent loader and
the in-memory session and artifact services the old constructor took one by one.
Two behaviour notes come with the split. AdkWebServer pinned host to 0.0.0.0;
the new classes bind loopback, which is a visible change for anyone reaching the
server from a container or a remote box, so the page now says so and names the
host parameter in prose. It prints no worked example on purpose: the only value
such a snippet could carry is either 127.0.0.1, which overrides the default with
itself, or 0.0.0.0, which is a copyable way to publish an unauthenticated server
on every interface, and AdkDevServer construction is already shown in full
earlier on the page. And AdkApiServer is the headless half of the same config,
so it gets a short section rather than a bare mention - the bundled Kotlin API
reference is still generated at 0.5.0 and documents none of these classes, so a
link there would not have helped. The "not meant for production" warning now
sits directly after the screenshot, where go.md, java.md and python.md put it.
The dependency blocks readers copy from still pinned 0.8.0, and so did the
examples project. Verified on Maven Central that 0.9.0 is published for every
artifact named across these pages: -core, -processor, -webserver, -litertlm,
-a2a and -integrations. Checked the 0.9.0 POMs before bumping: Ktor still
resolves to 2.3.13 and a2a-java-sdk-client to 1.0.0.Final, so the explicit pins
stay correct and the two comments citing them only needed their version
reference moved. The `Kotlin v0.x` support badges are deliberately left alone:
they record the release a feature landed in, not the current version.
Verified by compiling: every snippet added here was compiled verbatim against
the published 0.9.0 artifacts on JDK 17, and the whole examples project still
builds at 0.9.0. As a negative control, the old snippet still compiles at 0.9.0
but emits the deprecation warning, which is what makes this a 1.0 break rather
than a present-day one. Note the Kotlin snippet check only builds .kt files
changed in the PR, so it will not cover a markdown-only change like this.

* Upgrade Kotlin examples to adk-kotlin 0.8.0
The Kotlin examples project is pinned to adk-kotlin 0.7.0, which predates the
BigQuery agent analytics plugin and the JSON Schema constraint fields on
`Schema`. Bump the pin to 0.8.0 so snippets for those features can be written.
Only the three version strings change. Checked the 0.8.0 POM before bumping:
it still resolves Ktor 2.3.13 and kotlin-stdlib 2.1.20, so the explicit Ktor
pins and the 2.1.20 Kotlin/KSP plugin versions stay correct, and 0.8.0 removes
no API that the current snippets use.
Not compile-verified locally - no JDK 17 on hand, and the Gradle wrapper
rejects the JDK 26 that is. The PR check only builds .kt files changed in the
PR, so it will not cover this either; the first snippet PR on top of this one
is what will actually exercise the new version.
* Bump the Kotlin install instructions to 0.8.0
The dependency blocks readers copy from still pinned 0.5.0 - three releases
behind, and behind the examples project itself. Anyone following the quickstart
got an SDK without context caching, the Vertex AI memory and session services,
or the BigQuery analytics plugin, while the snippets on those same pages are
written against a newer API.
Verified on Maven Central that 0.8.0 is published for every artifact named
here: -core, -processor, -webserver, and -litertlm.
Only install instructions change. The `Kotlin v0.x` support badges are
deliberately left alone: they record the release a feature landed in, not the
current version.
The site rendered one language under two names. Tab labels were split
137 `TypeScript` / 53 `Typescript`, with three pages carrying both
spellings at once (custom-agents.md 7/7, patterns.md 1/7,
function-tools.md 4/1), and the language-support badges were split 67/18
the same way. Because pymdownx.tabbed slugifies tab labels to lowercase,
both variants rendered and linked fine, so no link check or build warning
ever flagged it -- it was visible only to readers, as two names for one
SDK.
Every user-visible occurrence is normalized to `TypeScript`, plus the two
inconsistencies that turned up while doing it. 80 changed lines, accounted
for exactly:
53 tab label === "Typescript" -> === "TypeScript"
18 badge span lst-typescript">Typescript -> TypeScript
3 prose mention cloud-run.md, mcp-tools.md, workflows/patterns.md
2 api-reference/index.md card heading and link text
1 badge div attr title="...Python and Typescript."
1 mkdocs.yml nav Typescript ADK -> TypeScript ADK
1 code fence ```javascript -> ```typescript on a .ts include
1 artifacts/index.md closing summary sentence
---
80
The first six rows are pure casing: 78 lines that differ from their
originals by nothing but `Typescript` -> `TypeScript`. The last two are
not, and are the reason this is not a `sed`:
llm-agents.md:872 fenced `--8<-- ".../capital_agent.ts"` as ```javascript.
It was the only javascript-fenced `.ts` include in docs/ (the other 189
TypeScript fences are correct), and it cost that one snippet its
TypeScript highlighting.
artifacts/index.md:1084 closed the page by naming languages and got the
list wrong. It described reaching the artifact methods "using Python's
context objects or directly interacting with the `BaseArtifactService` in
Java" -- a two-language enumeration at the end of a page that carries
Python, TypeScript, Go, Java and Kotlin tabs (11/10/10/10/11), and one
that contradicts :556, which correctly names four of them. The
enumeration is dropped rather than extended: the sentence now describes
the two ways to reach these methods -- through the context object, or
through `BaseArtifactService` -- which is what the page actually teaches
and does not rot when a sixth language is added.
docs/api-reference/index.md is included even though the rest of
docs/api-reference/ is generated output that must not be touched. That
tree holds 3,140 generated HTML files and exactly one hand-authored page:
this one. It is Markdown, it is the only api-reference entry mkdocs.yml
lists as `.md` rather than `index.html` (:272, :441), it uses Material
`grid cards` and `:fontawesome-*:` shortcodes, and it carries a
`CONTRIBUTORS:` note citing issues #1716 and #1717. Its TypeScript card
already said "TypeScript" twice in its body text while its heading and
link text said "Typescript"; those two are now consistent with the body.
No generated file is modified.
Not in this change: the broken `SseConnectionParams` sample in
mcp-tools.md (docs-ts/p6c-mcp-ts-sample) and the `@google/adk` example
version bumps (docs-ts/p6b-example-versions). Only the casing of the
prose line above that sample is touched here.
Verified: `mkdocs build` exits 0 with an empty warning set on both main
and this branch, and the two warning sets are identical. A rendered
before/after diff of the whole site shows every `__tabbed_*` id, every
tab radio id and every heading anchor unchanged. Zero `=== "Typescript"`
and zero `lst-typescript">Typescript` remain anywhere in the repo.
