Review comments at @A2A_CONFIGURATION.md:
- Around line 48-56: Update both client send calls to use the A2A text-part
shape with `content` containing `$case: 'text'` and the message value. Remove
the `HTTP+JSON/REST` protocol advertisement from the discovery card and update
the Agent Card Discovery description to list only the supported `JSON-RPC`
interface.
Review comments at @app/.well-known/agent-card.json/route.ts:
- Around line 4-6: Update the base URL construction in the route handler to use
the configured `NEXT_PUBLIC_APP_URL` value in production instead of
client-controlled `host` and `x-forwarded-proto` headers. Retain header-based
URL construction only in development.
Review comments at @app/api/a2a/route.ts:
- Line 134: Replace the client-facing `error?.message` fallback with a fixed,
generic error message, and keep the original error details in the server log.
Locate the error response handling around the `message` field.
- Around line 102-109: Add error and cancellation handling to the ReadableStream
around the rpcResult generator: catch iteration errors and pass them to
controller.error, and add a cancel handler that calls rpcResult.return?.() to
stop the generator when the client disconnects.
- Around line 12-27: Replace the duplicated `agentCard` definition in the
`/api/a2a` route with the shared card definition used by the well-known route,
including its skills and absolute URL. Ensure the shared card’s advertised
protocol binding matches the protocol this route actually serves; do not
advertise `HTTP+JSON/REST` here unless the route supports it.
- Around line 90-98: Add a bearer-token authentication check to the POST handler
before parsing the request or invoking jsonRpcHandler.handle, and reject
unauthorized requests; also enforce a request-body size limit before parsing. Do
not change the endpoint’s CORS policy without a defined access policy.
Review comments at @lib/agents/tools/a2a.tsx:
- Around line 37-44: Validate the parsed value in the `A2A_REMOTE_AGENTS`
configuration block before assigning it to `configuredAgents: require an array,
then retain only entries with string `name` and `url` properties so later
lookups cannot throw on malformed input.
- Around line 61-64: Update the fallback condition near the targetAgent lookup
so the first configured agent is selected only when no targetAgent was provided.
If a supplied targetAgent is unknown, do not route the request to another agent
or use that agent’s apiKey.
- Around line 122-141: Restrict the `sendMessage` fallback in the stream error
handler to cases where streaming cannot be started, rather than any error during
stream processing. Use the streaming capability from `client.getAgentCard()` to
decide whether to fall back, or skip fallback when `accumulatedResponse` already
contains streamed content; preserve partial responses without sending the task
twice.
- Line 163: Update the errorText handling in the remote A2A invocation to return
a generic error without exposing agentUrl or the raw error message to the model
or UI, while keeping those details in the server log.
- Around line 49-50: Validate `targetAgent` before assigning it to `agentUrl`:
allow direct URLs only when their host matches an explicitly configured agent in
`A2A_REMOTE_AGENTS`, and otherwise accept only configured agent names. Reject
unmatched URLs before they can reach the outbound request.
- Around line 112-113: Update the streamed task status handling in the
chunk-processing flow to read the state value from
chunk.statusUpdate.status.state instead of converting the status object itself
to a string.

98-102: The A2A section is numbered 6, but the SkyFi and geospatial branches use#### **3.**.The tool guideline numbering is consistent. The decision flow now lists A2A first. Mandatory-style rules in the prompt, such as "Geospatial Priority … MUST", can conflict with the new first rule only for requests that name a remote agent. This is acceptable. No change is needed.

Keep camera updates out of the map initialization lifecycle.
captureMapCenter writes a new mapData.cameraState on every moveend. This dependency therefore runs cleanup after a pan or zoom, removes the map, and creates a new instance. Cleanup does not save active drawRef features, and the map-mode effect does not rerun for this change. Drawing controls and in-progress drawings can be lost. Changes to position also trigger this teardown. Keep map creation independent of these changing values, and apply later camera or position updates without destroying the map instance.

@a2a-js/sdk 1.3.0 JavaScript Client sendMessageStream AbortSignal request options
💡 Result:
Yes. In **`@a2a-js/sdk` 1.3.0**, pass `RequestOptions` as the **second argument** to `sendMessageStream`; it supports a per-call `signal`:
```js
const controller = new AbortController();
const stream = client.sendMessageStream(request, {
signal: controller.signal,
});
for await (const event of stream) {
// Handle event
if (shouldStop) controller.abort();
}
```
The package’s 1.3.0 documentation says client methods accept `RequestOptions` with `signal`, and `sendMessageStream` is consumed as an async generator. ([npmjs.com](https://www.npmjs.com/package/%40a2a-js/sdk?activeTab=versions&utm_source=openai))
You can also pass other request options, such as `serviceParameters` for headers and `context`. The cited package page establishes those options for 1.3.0; it doesn’t show the full `RequestOptions` type declaration. ([npmjs.com](https://www.npmjs.com/package/%40a2a-js/sdk?activeTab=versions&utm_source=openai))

- 2: https://www.npmjs.com/package/%40a2a-js/sdk?activeTab=versions&utm_source=openai
Add a timeout and cancellation signal to the A2A request.
client.sendMessageStream can remain pending while the remote async generator remains open. The current requestOptions contains only authentication settings, so the stream has no per-call deadline. Create an AbortController with the tool's request timeout, pass signal: controller.signal in requestOptions, and clear the timer and abort the controller in a finally block that covers both the streaming request and its fallback.

Persist the agent reply in the completed task.
The completion status sets message to undefined. The preceding AgentEvent.message supplies a reply to the current stream, but the SDK does not persist that event in task history. A client that later calls GetTask receives a completed task without the agent reply. Set the completion status message to the agent response, or publish a response artifact.

Return a failure when the remote task fails.
If a stream ends with TASK_STATE_FAILED and no text, this branch records the state but leaves accumulatedResponse empty. Line 197 then reports that the task completed successfully. Handle failed, canceled, and rejected states before the success fallback. Include any text in status.message in the result. The protocol permits a message on a task status. (a2a-protocol.org)

In the statusUpdate handling branch, detect failed, canceled, and rejected task
states and return a failure result before the success fallback, including any
text from status.message. Preserve the existing success behavior for other
states.

Replace artifact text when an update does not request append.
If an agent updates the same artifact with append: false, this branch still adds the new text to accumulatedResponse. The result contains both the obsolete and replacement text. Track text by artifactId; replace it when append is false and append only when it is true. The SDK uses that distinction when storing artifact updates. (a2a-protocol.org)

Update the artifactUpdate handling in the response-accumulation flow to track
text by artifactId: replace that artifact’s accumulated text when append is
false, and append to it only when append is true. Preserve text from other
artifacts.
