Prompt Designer

Help users design and customize prompts for aish shell.

Workflow

Step 1: Check or Initialize

# Check if user has a prompt file
if [[ ! -f ~/.config/aish/scripts/hooks/aish_prompt.aish ]]; then
    # Create from template
    mkdir -p ~/.config/aish/scripts/hooks
    cp <aish-src>/src/aish/scripts/templates/aish_prompt.aish ~/.config/aish/scripts/hooks/
fi

# Read current content
cat ~/.config/aish/scripts/hooks/aish_prompt.aish

Step 2: Modify or Regenerate

Modify existing:

• Read current file
• Apply only requested changes
• Preserve existing customizations

Regenerate (when user asks):

• "重写", "重新生成", "create new"
• Generate completely new prompt
