* Prepare for archiving of copilot-sdk-java repo in favor of java directory in copilot-sdk
* Update README
* Update with latest `java` from `copilot-sdk`.
### 16:37 Prompt
I have added `copilot-sdk-00` to this VS Code workspace. The `copilot-sdk-00/java` directory **is** the Copilot SDK for which this `copilot-sdk-java.instructions.md` is the instructions.
Do a deep read of the source code in `copilot-sdk-00/java`.
Do a deep read of the existing `copilot-sdk-java.instructions.md`.
Suggest any updates based on what should be changed in `copilot-sdk-java.instructions.md`, based on your findings.
### 16:51 Response
Now I have a comprehensive picture. Let me summarize the findings and suggest updates:
---
Based on my deep read of the Java SDK source code and the current copilot-sdk-java.instructions.md, here are the updates I'd suggest:
## Issues Found
### 1. Incorrect: `session.setModel()` documentation is slightly wrong
The instructions show `session.setModel(modelId)` — this is actually correct (it exists on CopilotSession), but the full signatures should be documented:
- `setModel(String model)`
- `setModel(String model, String reasoningEffort)`
- `setModel(String model, String reasoningEffort, ModelCapabilitiesOverride modelCapabilities)` *(since 1.3.0)*
### 2. Incorrect: `PreToolUseHookOutput` API
The instructions show:
```java
var decision = new PreToolUseHookOutput().setKind("allow");
```
But actually `PreToolUseHookOutput` is a **record** with static factory methods:
- `PreToolUseHookOutput.allow()`
- `PreToolUseHookOutput.deny()`
- `PreToolUseHookOutput.deny(String reason)`
- `PreToolUseHookOutput.ask()`
### 3. Missing: `CopilotClientOptions` fields not documented
These are in the source but not in the instructions:
- `setRemote(boolean)` — Mission Control integration
- `setTelemetry(TelemetryConfig)` — OpenTelemetry export *(since 1.2.0)*
- `setSessionIdleTimeoutSeconds(int)` — Idle timeout *(since 1.3.0)*
- `setExecutor(Executor)` — Custom thread pool
- `setTcpConnectionToken(String)` — TCP security token
### 4. Missing: `ToolDefinition.createSkipPermission()`
A third factory method exists *(since 1.2.0)* that skips the CLI permission request entirely. The instructions only mention `create()` and `createOverride()`.
### 5. Missing: Session listing with filters
The instructions show `client.listSessions()` but don't mention the overload with `SessionListFilter` that can filter by `cwd`, `gitRoot`, `repository`, and `branch`.
### 6. Missing: `session.log()` with URL
The instructions show `log(message, level, ephemeral)` but there's also a 4-param overload:
```java
session.log(String message, String level, Boolean ephemeral, String url)
```
### 7. Missing: MCP Server Configuration
The instructions mention `setMcpServers()` in the SessionConfig options list but don't show how to configure them. There are two types:
- `McpStdioServerConfig` — Local/stdio-based servers
- `McpHttpServerConfig` — HTTP/SSE remote servers
### 8. Missing: Cloud Sessions / Remote features
The `setRemote(boolean)` option on client options and per-session GitHub token support for cloud/content-exclusion scenarios.
### 9. Missing: `ModelCapabilitiesOverride`
Vision/image support can be controlled via model capabilities override, but this isn't documented.
### 10. Missing: `EventErrorPolicy` enum values
The instructions mention `EventErrorPolicy.SUPPRESS_AND_LOG_ERRORS` but don't list the other value: `PROPAGATE_AND_LOG_ERRORS` (which is the default).
### 11. Missing: `onLifecycle()` typed overload
There's also `onLifecycle(String eventType, SessionLifecycleHandler handler)` for filtering specific lifecycle events.
### 12. Minor: `send()` return type
`session.send()` returns `CompletableFuture<String>` (the message ID), which is worth mentioning since it can be used for correlation.
---
## Recommended Priority
**High priority** (incorrect info):
- Fix#2 (`PreToolUseHookOutput` API)
**Medium priority** (missing important features):
- Add #4 (`createSkipPermission`)
- Add #7 (MCP server configuration examples)
- Add #3 (missing client options)
- Add #5 (session list filters)
**Low priority** (nice-to-have completeness):
- Expand #1 (setModel overloads)
- Add #6 (log with URL)
- Add #9-12 (minor additions)
Would you like me to apply any or all of these updates to the file?
### 16:52 Prompt
Yes. Apply all of these.
### 16:54 Response
Created 12 todos
Now I have the full file. Let me apply all the changes:
Starting: *Fix PreToolUseHookOutput API (incorrect)* (1/12)
Replacing 84 lines with 199 lines in [](file:///e%3A/workareas/awesome-copilot-00/instructions/copilot-sdk-java.instructions.md)
```
```
Completed: *Fix PreToolUseHookOutput API (incorrect)* (1/12)
All 12 updates have been applied to copilot-sdk-java.instructions.md:
1. **Fixed** `PreToolUseHookOutput` — now uses correct static factory methods (`allow()`, `deny()`, `ask()`) instead of the incorrect `new PreToolUseHookOutput().setKind("allow")`
2. **Added** `ToolDefinition.createSkipPermission()` section (since 1.2.0)
3. **Added** 5 missing `CopilotClientOptions` fields: `remote`, `telemetry`, `sessionIdleTimeoutSeconds`, `executor`, `tcpConnectionToken`
4. **Added** `SessionListFilter` with `setRepository()`, `setBranch()`, `setCwd()`, `setGitRoot()`
5. **Expanded** `setModel()` to show all 3 overloads (model, reasoning effort, capabilities)
6. **Added** `log(message, level, ephemeral, url)` overload
7. **Added** full MCP server configuration section with `McpStdioServerConfig` and `McpHttpServerConfig` examples
8. **Added** `EventErrorPolicy` enum values with explanations
9. **Added** `onLifecycle(String eventType, handler)` filtered overload
10. **Added** note that `send()` returns `CompletableFuture<String>` (message ID for correlation)
11. **Added** `ModelCapabilitiesOverride` section with vision/limits configuration (since 1.3.0)
12. **Added** `remote` option for Mission Control / cloud session integration
13. **Bonus:** Expanded `SessionHooks` example to include all 5 hook types (`onPreToolUse`, `onPostToolUse`, `onUserPromptSubmitted`, `onSessionStart`, `onSessionEnd`)
Made changes.
### 16:54 Prompt
In the "## Core Principles" section. Add a bullet point that describes how `Optional` is used in the API.
### 16:58 Response
Searched for text `Optional` (`copilot-sdk-00` · `java/src/main/java/com/github/copilot/sdk/json/*.java`), 10 results
Searched for text `Optional` (`copilot-sdk-00` · `java/src/main/java/com/github/copilot/sdk/json/InfiniteSessionConfig.java`), 13 results
Replacing 7 lines with 8 lines in [](file:///e%3A/workareas/awesome-copilot-00/instructions/copilot-sdk-java.instructions.md)
```
```
Added the bullet point describing how `Optional<T>`, `OptionalInt`, and `OptionalDouble` are used on config class getters to distinguish "not set" from explicit values, while setters accept raw types and return `this` for fluent chaining.
Made changes.
### 16:58 Prompt
Consider this code from the Java README.
```java
public class CopilotSDK {
public static void main(String[] args) throws Exception {
var lastMessage = new String[]{null};
// Create and start client
try (var client = new CopilotClient()) { // JDK 25+: comment out this line
// JDK 25+: uncomment the following 3 lines for virtual thread support
// var options = new CopilotClientOptions()
// .setExecutor(Executors.newVirtualThreadPerTaskExecutor());
// try (var client = new CopilotClient(options)) {
client.start().get();
// Create a session
var session = client.createSession(
new SessionConfig().setOnPermissionRequest(PermissionHandler.APPROVE_ALL).setModel("claude-sonnet-4.5")).get();
// Handle assistant message events
session.on(AssistantMessageEvent.class, msg -> {
lastMessage[0] = msg.getData().content();
System.out.println(lastMessage[0]);
});
// Handle session usage info events
session.on(SessionUsageInfoEvent.class, usage -> {
var data = usage.getData();
System.out.println("\n--- Usage Metrics ---");
System.out.println("Current tokens: " + data.currentTokens().intValue());
System.out.println("Token limit: " + data.tokenLimit().intValue());
System.out.println("Messages count: " + data.messagesLength().intValue());
});
// Send a message
var completable = session.sendAndWait(new MessageOptions().setPrompt("What is 2+2?"));
// and wait for completion
completable.get();
}
boolean success = lastMessage[0] != null && lastMessage[0].contains("4");
System.exit(success ? 0 : -1);
}
}
```
I want to get across the very important JDK 25 comment. What's the best place to encode that knowledge in the instructions?

Adds a new custom agent that guides Azure Verified Modules (AVM) owners through a structured, repeatable workflow to triage open issues across the AVM repos they maintain. Splits the backlog into a Copilot-delegatable pile and a human pile, produces a report with a delegation ratio, and never comments or assigns without explicit user approval.

The accessibility-report recipe and its companion doc used "assistant.message.delta" (dotted), which never matches the SDK event. The canonical name is "assistant.message_delta" (underscore), as documented in instructions/copilot-sdk-nodejs.instructions.md and used by the Python cookbook. Without this fix the streaming branch was dead and no incremental output was printed.
