Environment

  • Platform (select one):
  • [ ] Anthropic API
  • [ ] AWS Bedrock
  • [ ] Google Vertex AI
  • [x ] Other: MAX Subscription
  • Claude CLI version: 1.0.60 (Claude Code)
  • Operating System: Ubuntu 22.04 (WSL)
  • Terminal: Windows Terminal Version: 1.22.11141.0

Bug Description

While working with several Claude sub-agents, the terminal seems super sluggish, the agents take a very long time to execute commands, and I frequently get a warning saying pre-flight checks are taking too long when the agents try to use the Bash Tool.

Steps to Reproduce

  1. Define several agents using /agents
  2. Make the agents work in parallel
  3. Check for slowness

Expected Behavior

Agents should run their tasks smoothly and achieve improved performance, as each agent has a separate context window.

Actual Behavior

Slowness, the agent takes a very long time to complete tasks.
