2.5Error Recovery Patterns

One of the most powerful aspects of mapping ReAct onto a CLI is the agent's ability to recover from errors:

Stale Ref Recovery

Agent tries: playwright-cli click e11
Output: ERROR: ref e11 not found (page changed since last snapshot)

Agent observes: playwright-cli snapshot
→ button "Submit" is now [ref=e31]

Agent reasons: "The page re-rendered and refs changed. The submit button
              is now e31."

Agent acts: playwright-cli click e31
Output: success

Unexpected State Recovery

Agent tries: playwright-cli click e24   # checkout button
Output: success

Agent observes: playwright-cli snapshot
→ heading "Your session has expired. Please log in again."

Agent reasons: "Session expired during checkout. This is an environment
              issue. I need to log in again before continuing the test."

Agent acts:
  playwright-cli state-load auth-state   # restore saved login state
  playwright-cli goto "https://app.example.com/checkout"
  // Then retries the checkout
