Hypothesis

The v2 version of the prompt (released 2026-05-05) introduced an explicit defaulting clause that instructs the agent to assume USD for unspecified currencies, which contradicts the requirement to ask for clarification.

recommended
Remove the clause 'Always assume USD if not specified.' and restore the explicit instruction 'Never silently assume a default currency.' from version v1.
evidence
The defaulting clause was added in v2 (released 2026-05-05T12:47:00+00:00), and all 18 reported failures occurred after this rollout timestamp.
