Script, AI or agent?

Complete plan

To automate a task, the right tool is the simplest one that works: written rules when they are clear, AI only for fuzzy language, and an agent only with few rights, a human approval and a log.

  • 3-question check
  • English · Français

You will be able to

  • Tell apart a rule-based script, an AI (language model) and an agent
  • Choose written rules when they are clear, and AI only for free text, with a check
  • Use an agent only with the fewest rights possible, a human approval before any irreversible action, and a log
