BeliefNest dynamically and hierarchically constructs simulators within a Minecraft environment, allowing agents to explicitly represent nested belief states about themselves and others. This enables agent control in open-domain tasks that require Theory of Mind reasoning. The simulator provides a prompt generation mechanism based on each belief state, facilitating the design and evaluation of methods for agent control utilizing large langua","authors_text":"Koichiro Terao, Naoto Iwahashi, Rikunari Sagara","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2025-05-18T09:26:48Z","title":"BeliefNest: A Joint Action Simulator for Embodied Agents with Theory of Mind"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.12321","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:40a963553b9c6a40ab7d8715bbbc08923d004fbd740b8fd88a530d2c54f5fc4c","target":"record","created_at":"2026-07-05T11:05:02Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3b333517c550bb1e10e2bfbe7c1b175be105441783ed559ac46f20ed74ea42f1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.AI","submitted_at":"2025-05-18T09:26:48Z","title_canon_sha256":"eb3cd47406ffda7ff7016ace79326034f2e35b0e8b59c2819bbabeed7b647433"},"schema_version":"1.0","source":{"id":"2505.12321","kind":"arxiv","version":1}},"canonical_sha256":"e30da554f40979f157d786c605451c050feb67d8aefa2bb232aecb03c7341eb6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e30da554f40979f157d786c605451c050feb67d8aefa2bb232aecb03c7341eb6","first_computed_at":"2026-07-05T11:05:02.246033Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:05:02.246033Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uitfS7Ubln/bkmPVHB1CaipYz3URA/w9EQaqYbWFGMAMk6IbHYJWPSKp38VQWZ9KjezVTlH+ZBYMYtztiSj/DQ==","signature_status":"signed_v1","signed_at":"2026-07-05T11:05:02.246575Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.12321","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:40a963553b9c6a40ab7d8715bbbc08923d004fbd740b8fd88a530d2c54f5fc4c","sha256:df893a4567246daf0430bcc8abcf0bcf496704d24251b4b8cb5100b67af0cc03"],"state_sha256":"76b45d856bcfe79459a68f6240cf8b58d084d067a0d0f8996eea80c7f973215e"}
