Summary

• Remove the final persona tool allow-list filter from the main agent build flow.
• Keep system-injected tools such as web search and local computer-use tools available even when a persona defines an explicit empty tool list.
• Update regression coverage to assert that late system tools remain available.

Summary by Sourcery

Preserve system-injected tools when personas specify explicit tool lists, and update tests accordingly.

Bug Fixes:

• Ensure system web search tools remain available even when a persona defines an empty tool list.
• Ensure local computer-use runtime tools remain available for personas with empty tool lists.

Enhancements:

• Simplify persona tool handling by removing the final allow-list filter from the main agent build flow.

Tests:

• Extend main agent tests to cover retention of late web search tools for personas with empty tool lists.
• Add regression test to verify local runtime builtin tools remain available with empty persona tool lists.
