CLI crashing

[arishrehmankhan]

Describe the bug

CLI crashes when I give this prompt:

Research online using subagents and download the Claude/Copilot/AI agents skill which would be good while developing the @plan.md like frontend/backend/react skills. Try to install them by running cli commands instead of fetching and storing them in files, refer: https://github.com/skillcreatorai/Ai-Agent-Skills

This should be resolved in recent releases. Several versions since v0.0.410 include memory-related fixes - v1.0.6 improved sub-agent session stability and reduced memory usage, v1.0.12 fixed out-of-memory crashes from high-volume shell output, and v1.0.21 added automatic cleanup of idle shell sessions. If you're still seeing crashes on a current version, please feel free to reopen this issue.
