Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Adds support for streaming “acting chunk” intermediate tool outputs through the AGUI adapter and Spring Boot starters via a new configuration flag.

Changes:

• Introduces enableActingChunk in AguiAdapterConfig and wires it into StreamOptions.includeActingChunk(...).
• Exposes agentscope.agui.enable-acting-chunk in Spring Boot AguiProperties and passes it through MVC/WebFlux autoconfig.
• Extends adapter config unit tests to cover the new flag (and adds explicit reasoning-flag builder coverage).

This PR adds an enableActingChunk boolean configuration to the AGUI module, preparing for future support of ActivitySnapshot/ActivityDelta events. The change is a clean, well-structured configuration plumbing that spans the adapter config, the agent adapter wiring, Spring Boot properties, and both MVC/WebFlux auto-configurations. The implementation faithfully follows the existing pattern established by enableReasoning. Test coverage for the config layer is adequate. One notable observation is the default value inversion: StreamOptions.Builder.includeActingChunk defaults to true in core, but this PR sets AguiAdapterConfig.Builder.enableActingChunk to false. This does NOT cause a user-visible behavior change because AguiAgentAdapter.convertEvent() already silently drops acting chunks (they arrive with EventType.TOOL_RESULT and isLast=false, but the conversion only processes TOOL_RESULT when isLast=true). Still, a brief inline comment explaining the rationale would improve future maintainability.

[nitpick] The StreamOptions.Builder.includeActingChunk defaults to true in core, but this PR explicitly overrides it to false (via config.isEnableActingChunk()). While this does NOT change user-visible behavior (acting chunks are already silently dropped by convertEvent's event.isLast() guard), the inverted default may confuse future readers. Consider adding a one-line comment: // Explicitly gate acting chunks behind config — AGUI event conversion for chunks is not yet implemented.
