[synthesis] Ambiguous Tool Parameters Cause Divergent Agent Loops Across Models

Implement model-specific fallback logic: for Claude, add an 'ask\_user' tool to handle missing params; for GPT-4o, add execution-layer validation to catch hallucinated params; for Gemini, explicitly pass context in the tool description.

Journey Context:
When a required tool parameter is ambiguous, Claude acts as a validator \(asks user\), GPT-4o acts as an autocompleter \(guesses\), Gemini acts as an inferencer \(uses context\). This means agentic loops break differently: GPT-4o loops on execution errors, Claude loops on user-confirmation timeouts. A single fallback strategy fails; you must implement model-specific error recovery.
