Highlights

Notable C# changes that may require Java porting:

bb02de1 — [C#] Use event delegate for thread-safe, insertion-ordered event handler dispatch — may need Java equivalent

6415c40 — [C#] Remove unnecessary SemaphoreSlim locks for handler fields — review corresponding Java synchronization

cb94df9 — [C#] Deduplicate OnDisposeCall and improve implementation — review Java close() disposal

388f2f3 — Add permission checks for SDK-registered custom tools — new feature to port

9d998fb — Add SDK support for agent selection and session compaction APIs — new feature to port

279f6c4 — Require permission handler on session creation — API change to port

Pull request overview

Ports 28 upstream commits from github/copilot-sdk into the Java SDK, including a breaking permission-handler requirement, new session APIs (agent selection + compaction), and expanded event surface area.

Changes:

Breaking: require onPermissionRequest for createSession(SessionConfig) and resumeSession(String, ResumeSessionConfig); remove no-arg overloads and update E2E tests accordingly.
Add agent selection + session compaction APIs (listAgents/getCurrentAgent/selectAgent/deselectAgent/compact) and new AgentInfo JSON type.
Add new event types and extend existing event payloads (e.g., interactionId, copilotUsage, streaming delta metrics), plus update docs/changelog.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

checkstyle.org
- Triggering command: /opt/hostedtoolcache/CodeQL/2.24.2/x64/codeql/tools/linux64/java/bin/java /opt/hostedtoolcache/CodeQL/2.24.2/x64/codeql/tools/linux64/java/bin/java -jar /opt/hostedtoolcache/CodeQL/2.24.2/x64/codeql/xml/tools/xml-extractor.jar --fileList=/tmp/codeql-scratch-a0b8ba07f7cabbfc/dbs/java/working/files-to-index9945316311741484777.list --sourceArchiveDir=/tmp/codeql-scratch-a0b8ba07f7cabbfc/dbs/java/src --outputDir=/tmp/codeql-scratch-a0b8ba07f7cabbfc/dbs/java/trap/java (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

Configure Actions setup steps to set up my environment, which run before the firewall is enabled
Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
