Evidence claims:
- [sourced_fact] README: accompanies the paper and contains the core simulation module for generative agents and their game environment, with setup steps and a replay demo. · locator: README intro · source: https://github.com/joonspk-research/generative_agents
- [upstream_claim] Paper abstract: agents store a complete record of experiences in natural language, reflect and plan; evaluated as believable proxies of human behavior. · locator: abstract · source: https://arxiv.org/abs/2304.03442
- [sourced_fact] Apache-2.0 license; last push 2024-08-05. · locator: LICENSE file · source: https://github.com/joonspk-research/generative_agents/blob/main/LICENSE
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
