Cursor Agent terminal output is truncated or garbled with Powerlevel10k or another heavy prompt

Command output looks cut off or misformatted in Agent's terminal

Verified 2026-10-15 · Confirmed by 0 builders · Trust 50/100

Cause

Prompt themes such as Powerlevel9k and Powerlevel10k interfere with how Cursor captures inline terminal output for Agent.

Fix

Skip the theme when the CURSOR_AGENT variable is set, so Agent sessions get a simple prompt.

Apply

# ~/.zshrc
if [[ -z "$CURSOR_AGENT" ]]; then
  [[ -r ~/.p10k.zsh ]] && source ~/.p10k.zsh
fi

Affects: Cursor Agent terminal on zsh and bash, as of 2026-10
