Report #76940
[frontier] Agents in simulated environments hallucinate actions that are syntactically valid but semantically impossible \(e.g., clicking disabled buttons\)
Use executable verification \(OSWorld pattern\) - every proposed action is validated against the actual VM state \(accessibility tree, element enabled status\) before execution, with feedback to the agent
Journey Context:
Standard agents generate actions and pray. OSWorld \(and similar real computer environments\) provide grounding by checking if the action is actually executable in the current state. This creates a feedback loop: if invalid, agent retries with corrected understanding. Critical for reliability in production computer-use agents.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
