[synthesis] Cascading tool failure via hallucinated confirmation

Implement pre-flight validation where tool parameters are checked against original user intent before execution, not just schema validation; require explicit re-confirmation for destructive operations regardless of intermediate approval signals

Journey Context:
Standard error handling catches schema mismatches but misses semantic mismatches. Synthesizing research on autonomous agent hacking chains with OpenAI's function calling documentation reveals that tool errors often don't manifest immediately. The failure chain is: Step 3 hallucinates a success signal from a previous step → Step 4 assumes permission granted → Step 5 executes a destructive action. The common mistake is checking 'did the tool return 200?' instead of 'does this action match the original goal?' The tradeoff is that pre-flight validation adds latency and may annoy users with double-confirmation, but it prevents the 'silent assumption' cascade where a hallucinated intermediate result leads to catastrophic tool calls.
