Problem Description

I'm experiencing an issue with the tools compression feature in claude-kiro. When using the opencode functionality, built-in tools (such as the todo tool) cannot be executed because critical information about these tools is being stripped during compression. I suspect the compression logic has become too strict in recent changes, as this functionality was working correctly before the latest fix.

Environment Information

OS: Ubuntu

Steps to Reproduce

Run Opencode
Attempt to use a built-in tool (e.g., todo tool)
Observe that the tool fails to execute
Check the compressed output and notice that tool metadata/information is missing

Expected vs Actual Behavior

Expected: Built-in tools should execute properly when using opencode, with all necessary tool information preserved during compression.

Actual: Built-in tools fail to execute because the compression process strips away essential tool metadata and configuration information, making them unavailable at runtime.

Attempts Made

I reviewed the recent changes to the compression logic and noticed increased strictness in metadata filtering
I tested with previous versions before the compression fix was applied, and confirmed that built-in tools worked correctly

This appears to be a regression introduced by the recent compression improvements, where the logic is now too aggressive in removing what it considers "unused" information, but is actually critical for tool execution.

I can use the built-in todo tool. It's possible your single request is too large, causing excessive compression. Please disable unnecessary tools.
