Interface: ToolIdentityRule

Defined in: src/batteries/validation/types.ts:370

Requires a replayed tool result to name a tool the request actually declares.

Remarks

A ROOT CAUSE of the silent empty-generation class. Gemini matches a functionResponse.name against its functionDeclarations; a name that resolves to nothing — an opaque call id, or a tool no longer offered this turn — makes it return an empty candidate (parts: [{text: ''}], STOP, no candidatesTokenCount) a large fraction of the time. The gateway then forwards that as an ordinary finish_reason: stop with content: null and NO error, so the caller sees a successful turn that produced nothing.

Requires the tool registry; the evaluator skips this rule when none is supplied.
