Summary

Remove the built-in Grep and Glob tools. Agents can search files and contents through Shell. Recorded Grep and Glob calls remain expandable in conversation history.

Bundled installations update automatically. If you explicitly register either removed Files method in a custom composition, remove that tool entry before upgrading.

Verification

• On Windows 11 without ripgrep on PATH, Windows PowerShell 5.1 found files with Get-ChildItem and matching lines with Select-String.
• An existing default Host upgraded and started without a migration.
• The product build, affected tests, SDK checks, and dependency checks passed.

AI use

• Generative tooling made a substantive contribution

OpenAI Codex implemented the tool removal and ran local verification.

Checklist

• Tests cover the change and fail without it
• Format, typecheck and the affected suites pass locally
