Pull request overview

Automated dependency bump of @github/copilot from 1.0.57-3 to 1.0.57-4, with regenerated SDK types reflecting an upstream doc/schema tweak to ModelSwitchToRequest.contextTier.

Changes:

• Bump @github/copilot to ^1.0.57-4 in nodejs/package.json and test/harness/package.json (plus lockfiles).
• Regenerated ModelSwitchToRequest.contextTier docs across Node/Python/Go/Rust/.NET, with the Node type narrowing from ContextTier | null to ContextTier.

Cross-SDK Consistency Review

The contextTier support added to setModel/SetModel is consistently implemented across Node.js, Python, Go, .NET, and Rust — great work! 🎉

However, the Java SDK appears to be missing this update:

Java gaps found

1. SessionModelSwitchToParams.java (generated) — missing contextTier field:

   // java/src/generated/java/com/github/copilot/generated/rpc/SessionModelSwitchToParams.java
   public record SessionModelSwitchToParams(
       String sessionId,
       String modelId,
       String reasoningEffort,
       ReasoningSummary reasoningSummary,
       ModelCapabilitiesOverride modelCapabilities
       // missing: ContextTier contextTier
   ) {}

2. CopilotSession.setModel() — no contextTier parameter or SetModelOptions equivalent. The most complete overload today is:

   setModel(String model, String reasoningEffort, String reasoningSummary, ModelCapabilitiesOverride modelCapabilities)

   Compared to other SDKs that now support:

   • .NET: SetModelAsync(string model, SetModelOptions options) where SetModelOptions includes ContextTier
   • Rust: SetModelOptions::with_context_tier(ContextTier)
   • Node.js: setModel(model, { contextTier })
   • Python: set_model(model, context_tier=...)
   • Go: SetModelOptions{ ContextTier: &tier }

Suggested next steps

• Re-run the Java codegen (cd java && mvn generate-sources -Pcodegen) once the schema update is picked up — this should regenerate SessionModelSwitchToParams with the contextTier field.
• Add a setModel overload (or a SetModelOptions class) in CopilotSession.java that exposes contextTier, following the same pattern as the recently added reasoningSummary parameter.

This is a consistency gap, not a blocker for this PR — but it would be good to track as a follow-up to keep the Java SDK in parity with the others.
