ListDirectoryTool is broken #1164
Description
To Reproduce
Add dependency.
implementation("ai.koog:koog-agents:0.5.3")Run code.
import ai.koog.agents.ext.tool.file.ListDirectoryTool
import ai.koog.rag.base.files.JVMFileSystemProvider
suspend fun main() {
val tool = ListDirectoryTool(JVMFileSystemProvider.ReadOnly)
val result = tool.execute(args = ListDirectoryTool.Args(path = "/home/admin", depth = 2))
println(tool.encodeResult(result))
}It fails.
