Qualification: Reflexion: Language Agents with Verbal Reinforcement Learning
Shinn and colleagues provide direct evidence for one boundary in Kaal's wild-stage definition. Their Reflexion agent converts task feedback into reflective text, stores it in episodic memory, and uses it to improve decisions in later trials. In the controlled baseline, the environment resets without self-reflection or a memory update. The comparison supports Kaal's distinction between an isolated call and an architecture that preserves task experience. The qualification is strict. Reflexion stores private episodic memory for one agent. It does not create a validation pool, reputation, staking, slashing, citation attribution, or deliberation. The evidence therefore supports the persistence and residue boundary. It does not validate Kaal's full institutional bundle or establish that every wild-stage agent interaction is literally one shot.
