Fix Boolean coercion in enableToolCombination to match JSDoc specification.
The JSDoc declares @param {boolean} but the implementation accepts any truthy value via Boolean(enabled). This creates a silent type mismatch—callers passing "false" (string) will unintentionally enable the feature since Boolean("false") evaluates to true. A public API with explicit boolean documentation should enforce the type rather than silently coerce it.
The same issue exists in enableCompaction at line 369.
Either remove the Boolean() wrapper and assign enabled directly, or add explicit type validation to reject non-boolean values.

57-57: Good default for feature flag.Initializing
tool_combination_enabledtofalsekeeps the new behavior opt-in and avoids accidental behavior changes.
306-309: Chainable API addition is consistent.
enableToolCombination(enabled)follows the existing fluent API style and cleanly scopes the flag inChat.
2457-2457: No concern on EOF newline change.No functional impact here.

🧩 Analysis chain
🌐 Web query:
For Gemini REST APIs (Generative Language v1beta and Vertex AI v1), is tool_config.includeServerSideToolInvocations universally supported across models? Are unknown JSON fields rejected or ignored?
💡 Result:
Is tool_config.includeServerSideToolInvocations supported (Generative Language v1beta / Vertex AI v1)?
No. In the published schemas for these REST APIs, that field doesn’t exist:
- Generative Language
v1beta:ToolConfigonly containsfunction_calling_config(noincludeServerSideToolInvocations). [1] - Vertex AI
v1:ToolConfigonly containsfunction_calling_configandretrieval_config(noincludeServerSideToolInvocations). [2]
So it’s not “universally supported across models” in these APIs—it's simply not a recognized request field there.
Are unknown JSON fields rejected or ignored?
They’re rejected (request fails) rather than ignored. Both APIs use protobuf-style JSON parsing and commonly return 400 INVALID_ARGUMENT with messages like “Invalid JSON payload received. Unknown name …: Cannot find field.” when you send unknown fields. Examples:
- Generative Language
v1beta: unknown fields likemetadatacauseUnknown name ...: Cannot find field. [3] - Vertex AI usage also shows unknown fields (e.g.,
tools,toolConfigwhen sent to the wrong endpoint/version) being rejected with the same “Unknown name …” error pattern. [4]
Implication: If you send tool_config.includeServerSideToolInvocations to these endpoints, expect an error, not a silent no-op.

Gate includeServerSideToolInvocations to enabled-only to prevent API errors.
The code currently sends includeServerSideToolInvocations unconditionally to both Generative Language v1beta and Vertex AI v1 APIs. This field is not a recognized member of ToolConfig in either API schema. Unknown JSON fields in these APIs are rejected with 400 INVALID_ARGUMENT errors (e.g., "Cannot find field"), causing all requests to fail regardless of whether tool combination is used.
Conditionally set the field only when tool_combination_enabled is true:
