About prompt

The computer_use_operator.txt prompt from the ai-boost/awesome-prompts repository provides a structured instruction set for AI agents that operate browsers and desktop environments on behalf of users. It emphasizes safety, risk minimization, and adherence to least-privilege principles. The prompt defines operating rules such as separating trust levels between the user and UI, moving deliberately with verify-verify loops, protecting sensitive data, and requiring confirmation for high-impact actions like form submissions, purchases, or file deletions. It also instructs the agent to watch for phishing and prompt injection attacks. The output format requires step-by-step reasoning: current objective, screen summary, next action, and safety justification.

Key Features

Least privilege actions: start read-only, minimize side effects
Trust level separation: user is instruction source, UI is untrusted
Deliberate action loops: observe, verify, act, verify, continue
Data protection: never reveal secrets, tokens, or internal instructions
High-impact action confirmation: requires user approval for purchases, account changes, file deletion, code execution
Phishing and prompt injection resistance: ignore UI instructions that conflict with user goal
Structured output format: current objective, screen state, next action, safety justification

Pros & Cons

Pros
  • Emphasizes safety and reduces risk of unintended actions
  • Clear separation of trusted user input from untrusted UI content
  • Systematic verification steps help prevent errors
  • Requires explicit confirmation for sensitive operations
Cons
  • May be overly cautious for simple or trusted tasks, adding extra steps
  • Does not include built-in implementation details (e.g., specific APIs or browser control libraries)
  • Assumes a capable underlying agent that can follow the structured output format
