1.3The Agent Advantage: Adaptive Error Investigation

Consider this real-world example of how an agent thinks through an unexpected situation:

Step 1: OBSERVE  -- Login page loaded. Email and password fields visible.
Step 2: THINK   -- "I should fill in valid credentials and click login."
Step 3: ACT     -- Type email, type password, click submit.
Step 4: OBSERVE  -- Error banner: "Account locked after 5 failed attempts"
Step 5: THINK   -- "Unexpected error. This is not a test failure -- it is
                    test environment state. The account was locked by a
                    previous test run. I should report this as an
                    environment issue, not a bug."
Step 6: ACT     -- DONE fail "Account locked -- environment state issue, not a bug"

A deterministic script would simply fail with "Expected dashboard URL, got login URL." The agent provides a diagnosis.
