Add nil check in Flow.callLLM() after BeforeModelCallbacks but before

accessing Model.GenerateContent(). This prevents a nil pointer dereference

panic when an llmagent is created without a Model configuration.

The check is positioned after BeforeModelCallbacks to allow callbacks that

return cached responses to short-circuit execution without requiring a Model.

This provides a clear error message instead of a cryptic segmentation fault:

'agent %q has no Model configured; ensure Model is set in llmagent.Config'

Preserves valid use cases:

• Testing agent metadata/structure without running the agent
• BeforeAgentCallbacks that short-circuit before agent execution
• BeforeModelCallbacks that return cached responses

Fixes panic: runtime error: invalid memory address or nil pointer

dereference when sub-agents without Models were invoked.

Date: November 13, 2025 at 4:29 PM

This change re-introduces error as a possible return value for function tools. The previous removal of this feature led to poor error-handling patterns, as functions often need to signal failures from validation, I/O, or network calls. Restoring the ability to return errors allows for conventional error handling.

Fixes #260.

• Added comments

Commit: cffe3b0

Date: November 12, 2025 at 12:18 PM

• Add NewHandler() function to return http.Handler instead of requiring mux.Router - Created NewHandler() that returns standard http.Handler for better decoupling - Marked SetupRouter() as deprecated for backward compatibility - Allows users to use ADK REST API with any HTTP server/router, not just gorilla/mux

• Update api launcher to use NewHandler() instead of SetupRouter() - Refactored SetupSubrouters to use web.NewHandler() - Wraps handler with CORS middleware before registration - Uses http.StripPrefix for proper path handling - No breaking changes to web launcher interface

• Add example demonstrating NewHandler() usage with standard net/http - Shows how to use web.NewHandler() with net/http.ServeMux - Demonstrates framework-agnostic approach - Includes health check endpoint to show composability - Example works with any HTTP server/router, not tied to gorilla/mux

• Resolve PR feedback: remove SetupRouter and update example to use launcher.Config

• Clean up comments in NewHandler and setupRouter

Removed comments about the preferred integration method and the public SetupRouter helper.

• Fix linter issues: handle w.Write error and format with goimports

• Fix missing newline at end of api.go

Add a newline at the end of the file.

• Fix goimports formatting: remove trailing blank line and handle w.Write error

Implements a remote a2a agent.

An agent can be created as `remoteagent.New(remoteagent.A2AConfig{...})`.

The agent can be configured with either an `a2a.AgentCard` or an `AgentCardSource` pointing to a local file or an http resource.

Other options contain configurations for the various steps of execution: card resolution, message send configuration, client creation.

For remote agent input:

1. If the last session event is a user function tool response: send content parts as new message parts with the task and contextID matching those on the matching function tool call.

2. Combine parts from all the events after the last event authored by the remote agent and present them as a single user message.

For remote agent output:

1. `TaskStatusUpdate` event parts are converted to thoughts, unless it's the final task status updates.

2. Empty `TaskArtifactUpdate`s (no parts) are skipped.

3. Every event has a `CustomMetadata` with task and context IDs, the original A2A request and a matching A2A event.

4. If an error is generated during an execution it's converted to a session event with ErrorMessage.

These are slightly different from Python, but changes changes were made based on the implementation of `adka2a.NewExecutor`, I'll open a bug in their tracker to reconcile implementations.

Commit: 37e0403

Date: October 24, 2025 at 6:57 AM

1. `getUserFunctionCallAt` returns a non-nil response if the last session event is a user function call response.

2. `toMissingRemoteSessionParts` collects parts from all the events not present in the remote agent session. An event is considered present in a remote session if there's an event at a higher index with remote agent as an author.

3. `presentAsUserMessage` takes an event authored by another agent and converts it to a user event describing the provided event, eg:

• Move `adka2a.toMapStructure` to `internal/utils/ToMapStructure`. The utility is used by `adka2a` and `remoteagent` for converting structs to metadata `map[string]any` values.
• Rename and export utility functions for creating metadata keys. Python adds `adk_` prefix for keys it stores in a2a metadata, and `a2a:` prefix for keys it stores in `session.Event.CustomMetadata`, I'm doing the same.

Executor invokes an ADK agent and translates session.Events to a2a.Events according to the following rules:

• If the input doesn't reference any `Task`, produce a `TaskStatusUpdateEvent` with `TaskStateSubmitted`.
• Right before `runner.Runner` invocation, produce `TaskStatusUpdateEvent` with `TaskStateWorking`.
• For every `session.Event` produce a `TaskArtifactUpdateEvent{Append=true}` with transformed parts.
• After the last `session.Event` is processed produce an empty `TaskArtifactUpdateEvent{Append=true}` with `LastChunk=true`, if at least one artifact update was produced during the run.
• If there was an `LLMResponse` with non-zero error code, produce a `TaskStatusUpdateEvent` with `TaskStateFailed`.

Else if there was an `LLMResponse` with long-running tool invocation, produce a `TaskStatusUpdateEvent` with `TaskStateInputRequired`.

Else produce a `TaskStatusUpdateEvent` with `TaskStateCompleted`.

There's no `TaskAuthRequiredState` production rules at the moment, because A2A assumes an Agent is still executing while waiting for auth credentials. A proper integration will require more research and planning.

Event processing logic required for adka2a adapter.

• If there was an `LLMResponse` with non-zero error code, produce a `TaskStatusUpdateEvent` with `TaskStateFailed`.

Else if there was an `LLMResponse` with long-running tool invocation, produce a `TaskStatusUpdateEvent` with `TaskStateInputRequired`.

Else produce a `TaskStatusUpdateEvent` with `TaskStateCompleted`.

Python's ReadonlyContext/CallbackContext/ToolContext will allow

to access user id, branch, etc.

In the mean time, fix the tool.Context so it doesn't allow to

access to InvocationContext.

And add tests.

• Fix LoadArtifactsTool

There were two issues with load artifacts tool:

Unmarshalling json string array, it was treating string array as []any instead of []string, because of it it wasn't converting properly, leaving the artifactsName array empty.

The prompt wasn't completely right, the older prompt ran into issues like failing to process the artifact since it thought it could load them once and be done. But we want it to issue the load_artifact function call every time it needs to access them. I've asked about the issue to Java adk developer and they fixed it on their side as well.

I've also added example where I insert two artifacts and you can ask the agent about it and it can describe them without issues.

• Add memoryservice with in-memory implementation.

Reflects

https://github.com/google/adk-python/tree/e45c3be23895b5ec68908ad9ee19bd622dcbd003/src/google/adk/memory

It currently operates with session.Session. I'd follow up regarding the

use-cases for Session vs StoredSession and update if needed in future

PR.

Inmemory implementation is based on the 2-level map: {appName, userID} ->

sessionID -> {event + eventWords}

eventWords is a precomputation to fetch based on the read request words.

1. Used t.Context() in tests instead of ctx.Background()

2. Minor updates to the in-memory service implementation:

* no error on delete not_found

* required fields set validation

Commit: ff5f5ed

Date: August 19, 2025 at 7:27 AM

When an agent is created, adk automatically sets a parent for subagents.

This is done in the "agent" package.

For LLMAgent creation this means, it's needed to propagate "self" to

this code to ensure each subagent.Parent is set with a proper concrete

type of llmagent (and not just a base agent).

To get rid of the "self" field in the public API, we can move the agent

tree setup to an internal package, used by runner on creation.

Also, this shows an example of propagating data from runner to the

agent.

Such propagation will be done only for 2 cases:

• agent hierarchy (created by runner, needed by LLMAgent for transfer

logic).

• agent run config (set by users to control agents).

To sync with g3. Genai lib version 1.13 client generated URLs with

double //. This was captured by httprr.

But internally we use version genai 1.20 and its client has proper / in

the URIs.

This diff caused test failures internally due to httprr URL

mismatch.

• Move llm agent code to new packages.

1. Now it uses new session, llm, agent, llmagent packages.

2. LLMAgent request processors are now moved to the internal package.

3. Test case logic is kept the same everywhere.

4. Diffs with the doc (these are temporary to simplify the

migration):

* Tool interface has ProcessRequest method and llm.Request has Tools

field. This is to keep current request_processors logic for

llmagent.

* agent.Config accepts Self field to allow setting correct entity as a

parent.

• Add agent_context implementation.

It's mostly a placeholder for now.

agent.NewContext(...) will be used by the runner or agent packages to

create a new context for each agent Run call.

• Update runner from types package.

Now runner uses new packages: session, agent.

There is only types.AgentRunConfig but this will be updated in

subsequent PRs.

Remove internal runner -- because callback logic (the only logic there)

is now moved to agent, wrapping each agent Run.

• Update workflow agents to use new packages.

Workflow agents are now structured as:

agent/workflowagents

loopagent/

sequentialagent/

And they are created now with

loopagent.New(...)

sequentialagent.New(...)
