What's Wrong?

Bug Description

After auto-update to Claude Desktop 1.9659.2 (2026-05-29), computer-use tools
disconnect after the first use in Code mode. The tools are available on the
first turn but unavailable in all subsequent turns.

Environment

• Claude Desktop version: 1.9659.2
• OS: Windows 10/11
• Mode: Code (local agent / bridge session)
• Plan: Pro/Max

Steps to Reproduce

1. Open Claude Desktop in Code mode
2. Use any computer-use tool (e.g. screenshot, request_access)
3. Send a follow-up message in the same session
4. computer-use tools are gone — ToolSearch returns no results

Expected Behavior

computer-use tools remain available throughout the session (worked in previous version)

Actual Behavior

Tools disconnect after first use. Every new turn triggers:
[LocalAgentModeSessionManager] Bridge session: disabling renderer-dependent tools

Log Evidence

File: %APPDATA%\Claude\logs\main.log

First occurrence of "renderer-dependent" in logs: 2026-05-29 08:11:48
(Zero occurrences before this date = regression introduced in 1.9659.2)

Repeated pattern every turn:
2026-05-29 08:11:48 [info] [LocalAgentModeSessionManager] Bridge session: disabling renderer-dependent tools
2026-05-29 08:12:50 [info] [LocalAgentModeSessionManager] Bridge session: disabling renderer-dependent tools
2026-05-29 08:14:09 [info] [LocalAgentModeSessionManager] Bridge session: disabling renderer-dependent tools

Additional Notes

• Toggle off/on in Settings > General does NOT fix the issue
• Restarting Claude Desktop does NOT fix the issue
• computer-use works exactly ONCE per fresh session start, then disappears
• Previous version had no "renderer-dependent" messages in logs at all

What Should Happen?

computer-use tools (screenshot, request_access, etc.) should remain available throughout the entire session in Code mode, as they did before version 1.9659.2.
