Tips for All Terminal AIs

Always start in the right directory:

cd ~/Documents/my-project

This helps the AI understand your project structure.

Be Specific About Files

Tell the AI which file to work on:

  • "Edit introduction.md"

  • "Read chapters/chapter-1.md and improve it"

Work Section by Section

Don't ask for everything at once:

  1. "Improve the opening paragraph"

  2. "Now make section 2 clearer"

  3. "Add a conclusion"

Give Context

Tell the AI what you're writing:

  • "This is a blog post for developers"

  • "This is a user manual for beginners"

  • "This is a sales proposal"
