Minor ML Update: Clearer Outcomes for Tool Calls — Frontier

Clearer Outcomes for Tool Calls is now available to Frontier customers.

When a tool call fails, times out, or returns no results, users will now see a clearer explanation of what happened and, where applicable, guidance on what to do next. This makes unsuccessful tool calls easier to understand and reduces ambiguous or incomplete assistant responses.

Technical Restrictions

This initial release primarily covers Agent Studio plugins. MCP failure transparency and more specific action-error messages are not included in this release and are being handled as separate follow-up work.

Future Release Dates:

• Standard: September 14, 2026
• Basic: September 17, 2026
