Termination Conditions

How does an agent know it is done?

Explicit vs Implicit

• Implicit: The LLM says "I am done." (Risky. It might lie or be lazy).
• Explicit: The Tool validates the work.

def check_completion(state):
    # Don't ask the LLM "Are you done?"
    # Ask the filesystem "Does file.txt exist?"
    if os.path.exists("report.pdf"):
        return "END"
    return "continue"

Build graphs where the Exit Condition depends on the Environment (tools), not just the Language Model's opinion.
