📝 Feature Summary

Agents on kagent can execute shell commands via the built-in bash tool command, the timeout is currently hardcoded

❓ Problem Statement / Motivation

Agents deployed on kagent can execute shell commands via the built-in bash skill tool, the timeout is currently hardcoded:

30 seconds for general commands
60 seconds for commands containing python

If an agent runs a longer task, the command is killed with a timeout error.
There is currently no way to configure this timeout without modifying the kagent source code.

💡 Proposed Solution

Support an environment variable:

KAGENT_COMMAND_TIMEOUT=<seconds>

When unset or invalid, keep existing defaults (30s / 60s for python)
