* Add A2A consuming quickstart for Kotlin
adk-kotlin has been able to consume remote A2A agents since 0.6.0, and the docs
had no Kotlin page for it. This adds one alongside the Python, Go and Java
quickstarts, plus its nav entry.
A new page rather than a tab: docs/a2a has no tab groups at all, it is one page
per language, so this follows the section's own shape.
Two dependencies are needed, not one. The a2a artifact publishes the A2A SDK as
runtime-only, and A2AAgent's httpClient parameter defaults to JdkA2AHttpClient(),
so a2a-java-sdk-client has to be on the compile classpath as well. That number
was established by compiling, not by reading module metadata: the a2a artifact
alone fails with "Cannot access class 'A2AHttpClient'", and adding the client
artifact is sufficient -- spec and the jsonrpc transport arrive transitively.
Only the consuming side is documented, because that is all that exists: no
webserver source at v0.7.0 mentions a2a, so there is no Kotlin equivalent of the
exposing quickstarts. The page says so and links to the Python and Java ones.
A2AAgent is a suspending factory, and the implementation class behind it is
internal, so the factory is the only way to construct one. The snippet notes it.
Verified end to end rather than by compiling alone: served a real agent card
from a local server and ran the snippet, which fetched it, parsed it and wired
the remote agent in as a sub-agent --
"Root agent root_agent delegates to prime_agent".
* Correct the agent card claims and make the server step usable
A2AAgent does not read the remote's name from the card: the name is the
caller's, and independent of what the card advertises. It does not read the
transport either, which is hardcoded to JSON-RPC. What the card supplies is
the description and the streaming capability.
The server step told readers to start a server without saying how, and the
two obvious candidates do not work: adk-kotlin parses A2A 1.0 cards, which
require supportedInterfaces with a protocolBinding, and the adk-java and
adk-python samples both publish 0.3-style cards that A2AAgent rejects with
AgentCardResolutionError. State that, and give a minimal card verified by
running the snippet against it.
Also fix the root agent instruction, which referenced dice-rolling the agent
cannot do; match the Java snippet's prime-delegation wording.
* Point the A2A quickstart at the adk-python sample server
The page claimed neither the adk-java nor the adk-python sample works as the
server for this quickstart. The adk-python half is wrong. adk-python does not
serve its `agent.json` verbatim: `fast_api.py` parses it through
`_compat.parse_agent_card`, and under a2a-sdk 1.x that parse promotes the
legacy `url` and `preferredTransport` into `supportedInterfaces`. The dependency
is `a2a-sdk>=0.3.4,<2`, so a fresh install resolves to 1.x and the card on the
wire is A2A 1.0 - exactly what the Kotlin client requires.
So the page now names a server a reader can actually start, instead of asking
them to hand-write a card:
adk api_server --a2a --port 8001 \
contributing/samples/a2a/a2a_basic/remote_a2a
Its card is served under the agent's own prefix, and the snippet's agentCardUrl
follows it to http://localhost:8001/a2a/check_prime_agent. Confirmed the route
prefix in `attach_a2a_routes_to_app` and that the sample card's own `url`
already points there.
The adk-java half of the claim was correct and stays: `a2a_server` is pinned to
the 0.3.x A2A SDK and serves a 0.3 card. That, and the A2A 1.0 requirement it
illustrates, move into a note. The hand-written card survives as a collapsible
fallback for readers bringing their own server.

* 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.
* Add Kotlin snippet for the CallbackContext memory-write helpers
adk-kotlin 0.7.0 added addEventsToMemory and addMemory to CallbackContext,
alongside the addSessionToMemory the page already shows in Kotlin. They cover
the cases addSessionToMemory cannot: a chosen subset of events, and facts you
construct yourself rather than letting the service derive them.
Compiling changed the shape of this snippet. The obvious version read the
current turn's events off context.invocationContext, but that property is
internal -- CallbackContext exposes no way to reach the session. So
addEventsToMemory takes events the caller already holds, and the snippet says
so rather than quietly implying otherwise.
Both helpers, and addSessionToMemory, throw IllegalStateException when the
runner has no memory service. That is a runtime failure with nothing at compile
time to warn you, so the page states it. Verified by running both paths:
"Cannot add events to memory: memory service is not available." and
"Cannot add memory: memory service is not available."
Badged Kotlin v0.7.0, verified rather than assumed: neither helper exists on
CallbackContext at v0.6.0.
Appended to the existing MemoryExample.kt, already registered, so CI compiles
and lints it.
* docs: clarify CallbackContext memory methods and their default behavior
* Add Kotlin snippet for DebugLoggingPlugin
The Kotlin logging page covered LoggingPlugin's console output but not
DebugLoggingPlugin, available since adk-kotlin 0.6.0, which records the same
activity in full to a YAML file instead of truncated console summaries. Both
plugins override the same twelve callbacks, so the difference really is only
fidelity and destination.
Transcluded from the existing LoggingExamples.kt rather than written inline,
matching the rest of the page and keeping it in the compile regression suite --
the file is already registered in files_to_test.txt.
The sample passes includeSystemInstruction = false, since the plugin's KDoc
cautions that it writes raw prompts, tool arguments and session state to disk.
Verified against the upstream test that the flag records has_system_instruction
in place of the instruction text rather than dropping the field, and the
comment names that field so it can be found in the output.
outputPath is left at its default rather than passed explicitly; the default
filename is given in the prose instead, so the snippet does not imply the
parameter is required.
Page badge left at Kotlin v0.1.0: the other snippets on the page have worked
since then, so the version requirement for this one is noted in the prose.
* docs: add Kotlin version support tag to debug logging documentation
* Document how to check whether the context cache was used
The caching page explained how to turn caching on and never how to tell whether
it is working. CacheMetadata has been available since adk-kotlin 0.6.0 and is
undocumented: adk-python has fourteen code references to cache_metadata, while
adk-docs mentions it twice, both incidental -- a BigQuery schema table and a
bullet in the Live dev guide.
The snippet reads it from Event.cacheMetadata and covers both states the type
can be in, because the constructor enforces the split: cacheName, expireTime and
invocationsUsed must either all be set (an active cache) or all be null (the
fingerprint-only state used for prefix matching before a cache exists).
Notes that token counts live on LlmResponse.usageMetadata rather than here,
which the KDoc calls out to avoid duplication and a reader would otherwise
reasonably look for on CacheMetadata.
Badged Kotlin v0.6.0 and verified rather than assumed: the snippet compiles
against a temporary 0.6.0 pin as well as the current 0.7.0 one.
Transcluded and registered, so CI compiles and lints it. Exercised all four
paths with synthetic events: no metadata, fingerprint-only, active, and active
with expireSoon true.
* Correct when CacheMetadata is present on an event
The section claimed every event backed by an LLM response carries a
CacheMetadata. It does not: LlmResponse.cacheMetadata is null when caching
is disabled and also when the call produced no cache information, so the
claim was wrong even with caching on.
Say "can carry", name both null cases, and explain why the snippet checks
before reading. The snippet's own comment made the same overstatement.
* docs: clarify the behavior of expireSoon and cache status in documentation and snippets
adk-kotlin 0.7.0 added a plugins parameter to the agent-based InMemoryRunner
constructor. App.plugins already existed at 0.6.0, so this is an ergonomic
shorthand rather than a new capability, but it is the form a Kotlin reader
should see and the plugins page had no Kotlin at all.
Two tab groups rather than one. The Register group's prose refers to
"the CountInvocationPlugin plugin defined in the previous section", so a Kotlin
tab there alone would point at a class the page never defines in Kotlin. Adding
the Create group as well makes the pair self-contained.
Kotlin now appears in two of the page's nine groups; the remaining seven are
per-callback detail. Whether to finish the page is a separate decision.
Plugin declares exactly one abstract member, name -- all twelve callbacks and
close() have defaults -- so a custom plugin only overrides what it needs. The
snippet overrides beforeAgent and beforeModel, matching the callbacks the
surrounding prose describes.
Transcluded and registered, so CI compiles and lints it. Also run: the runner is
constructed with the plugin wired, and invoking beforeAgent twice prints
"[Plugin] Agent run count: 1" then 2, so the counter callbacks work.
* Upgrade Kotlin examples to adk-kotlin 0.7.0
The Kotlin examples were pinned to adk-kotlin 0.5.0, which predates the
context caching, Vertex AI memory, and RAG retrieval APIs. Bump the pin to
0.7.0 so snippets for those features can be added.
Three consequences of the bump are handled here:
- `ExperimentalResumabilityFeature` was removed in 0.7.0, so RunConfigExample
no longer opts into it. The annotation class is gone, not merely deprecated,
so this is a hard compile break rather than a warning that could be deferred.
- The Vertex AI session and memory services expose Ktor's `HttpClient` as a
defaulted constructor parameter, so any snippet naming them needs Ktor on the
compile classpath, not just at runtime.
- The `resolutionStrategy` block forcing kotlin-stdlib 2.1.20 is now dead. It
worked around 0.5.0 publishing a stdlib newer than this project's compiler;
0.6.0 fixed that upstream. Verified that the highest stdlib on the compile
classpath is still 2.1.20 without it.
Also fixes two unrelated snags found while validating the above:
- `check_kotlin_snippets.sh` walked `examples/kotlin` without pruning build
output, so after any local build it reported every generated KSP file as an
unregistered snippet. CI only ever ran it against a clean checkout, so the
bug was invisible there.
- A transclusion path in logging.md was split across two lines, so the include
never resolved and the code block rendered empty.
* Fix broken links to adk-python plugin samples
The three plugin sample links 404. adk-python renamed
`contributing/samples/plugin/` to `contributing/samples/plugins/`; the
directory contents are otherwise unchanged, so only the path segment moves.
This is what the repo-wide `link-check` job has been failing on. It is
unrelated to the 0.7.0 upgrade in this PR, but the check gates the merge and
the fix is confined to the three URLs.
Verified all three targets return 200.
* Add Kotlin snippets for Memory Bank and RAG memory
The memory page documented `VertexAiMemoryBankService` and
`VertexAiRagMemoryService` for Python and Java only; the Kotlin tab stopped at
the in-memory service. Both are available in adk-kotlin as of 0.7.0, so add
the two missing tabs.
Both services declare an `internal` primary constructor, so the snippets use
the public secondary one that takes project/location plus the engine or corpus
id -- reading the primary signature alone gives a constructor callers cannot
invoke.
The page's language-support badge stays at Kotlin v0.1.0: it marks when Kotlin
support for the page was introduced, and the other six Kotlin snippets on it
have worked since then.
The remaining diff in MemoryExample.kt is ktlint bringing pre-existing lines
into line with the repo style, which the linter now gates on because the file
is touched here.
* Correct the ragCorpus contract and wire both services to a Runner
Three fixes from review:
- The `rag_memory` KDoc claimed `ragCorpus` accepts a bare id or a full
resource name. It is the opposite: `normalizeCorpusName` does
`require(!ragCorpus.startsWith("projects/"))` and throws on a full name. The
Python tab directly above this snippet passes a full resource name, so a
reader switching tabs would have hit an IllegalArgumentException with a
comment telling them it was fine. The note now states the bare-id rule and
calls out the divergence from Python explicitly.
- Dropped "the primary constructor is internal" from the rendered snippet. It
is a note for reviewers, not for readers, who cannot see that constructor.
It stays in the PR description.
- Both snippets stopped at a factory function while the surrounding prose says
"instantiating the service and passing it to the Runner" and the Python tab
shows exactly that. They now build the service and pass it to a Runner.
* Upgrade Kotlin examples to adk-kotlin 0.7.0
The Kotlin examples were pinned to adk-kotlin 0.5.0, which predates the
context caching, Vertex AI memory, and RAG retrieval APIs. Bump the pin to
0.7.0 so snippets for those features can be added.

directory contents are otherwise unchanged, so only the path segment moves.

unrelated to the 0.7.0 upgrade in this PR, but the check gates the merge and
the fix is confined to the three URLs.
Verified all three targets return 200.
* Add Kotlin snippet for the Knowledge Engine retrieval tool
The Knowledge Engine integration page only showed Python. `VertexAiRagRetrieval`
landed in adk-kotlin 0.7.0, so add a Kotlin tab and advertise Kotlin support in
the page badge.
Retrieval runs inside the model through the Gemini-native `vertexRagStore` kind
rather than as a locally executed tool, so the snippet configures the corpus via
`VertexRagStoreRagResource` and leaves invocation to the model.
Registers the new file in files_to_test.txt so it stays in the compile
regression suite.
* Use the conventional package for the RAG retrieval snippet
RagEngine.kt declared `package integrations`. Every other snippet in the tree
uses `com.google.adk.kt.examples.<area>`. It compiled either way because the
source root is `snippets/` and Kotlin does not require the directory to match
the package, so nothing would have caught it.
Also worth flagging for anyone reading this alongside the memory snippets: the
two APIs take opposite corpus formats. `VertexAiRagRetrieval` here wants the
full `projects/.../ragCorpora/...` resource name, while
`VertexAiRagMemoryService` wants a bare corpus id and rejects the full name.
That is the library's doing, not a docs inconsistency.
- Add pip install "google-adk[gcp]" step to Eventarc Prerequisites.
- Clarify datacontenttype inference defaults and specify application/json in snippet prompt.
- Update Runtime Lambda table entry to use ctx.session_id and note support for payload and Context.
- Update OMIT table entry to list all mandatory attributes (type, source, bus, id, specversion).

The memory docs and the express-mode weather agent notebook referenced
`adk.tools.preload_memory_tool.PreloadMemoryTool()`, which raises
`AttributeError: module 'google.adk.tools' has no attribute
'preload_memory_tool'` because the submodule is not exposed via the
package's lazy `__getattr__`.
Use the documented public API `from google.adk.tools import preload_memory`
