Singapore tax,

Ask about GST, income tax, corporate tax, or SRS. Anything personal is routed to a human advisor.
A multi-step tax agent: every reply shows the routed model, tokens, and cost, plus a step trace when tools ran.
- Click the GST chip (or ask about the GST registration threshold). The reply cites SGD 1,000,000 and the badge under it reads "Routed to GPT-4o mini" with tokens and cost.
- Click Multi-step: the agent chains lookup_tax_info then calculate_tax_estimate in one turn. Expand "Agent steps (2)" in the reply to see each tool's input and output.
- Click SRS: personalised questions route to Claude Sonnet 4.6 and escalate to the advisor queue with a case number.
- Click PII: a question containing an NRIC routes to Claude Haiku 4.5 under the pii-sensitive rule.
- Use New chat to start over; past conversations stay in the history sidebar (this browser only).
