What it means

A tool call, command, or model response did not complete from the agent manager point of view.

Most common causes

  • Command waiting for interactive input
  • MCP server call never returns
  • Auth token expired during the task
  • Conversation context or tool payload became too large

Fastest fix

  • Cancel the task and run the command manually
  • Open a new chat with a smaller request
  • Disable recently added MCP servers
  • Restart the IDE if cancel does not work

Safe fix

  • Use commands with non-interactive flags
  • Set timeouts in custom MCP servers
  • Ask the agent to plan before running long commands
  • Keep generated logs small and readable

What not to do

  • Do not approve repeated identical commands without seeing output
  • Do not leave package installers waiting for prompts
  • Do not continue a stuck session for critical changes

How to confirm the fix

Run the smallest reproducible command first, then retry the agent task only after authentication, quota, and tool discovery are stable.

ps aux | grep -i node
tasklist | findstr node
git status --short
