This setup enables LLMs to define, invoke, and evolve their own tools through programmatic interaction with a live REPL. By embedding Lisp expressions within generation and intercepting them via a middleware layer, the system allows for stateful external memory, reflective programming, and dynamic tool creation. We present a design framework and architectural principles to guide future implementations of interactive AI systems that integrate symbolic programming with ne","authors_text":"Jordi de la Torre","cross_cats":["cs.AI"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.PL","submitted_at":"2025-06-08T20:12:06Z","title":"From Tool Calling to Symbolic Thinking: LLMs in a Persistent Lisp Metaprogramming Loop"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.10021","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":"sha256:4931668a0e0c062a2f02b71d8a14d7268bf2dc96fa5f96405e9e6b981348e231","target":"record","created_at":"2026-07-05T11:20:15Z","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":"27cdaa0bf86b1ea6336b5e055b6a4a64e27821994353f8a5b99328a866af4ac0","cross_cats_sorted":["cs.AI"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.PL","submitted_at":"2025-06-08T20:12:06Z","title_canon_sha256":"22d0e9670492fdc18120a12de180f2042dfa8c9010c55de4f064cf39aa167284"},"schema_version":"1.0","source":{"id":"2506.10021","kind":"arxiv","version":1}},"canonical_sha256":"c4761165b18e469a912719e696833825b422369bd2e19e124ee4e41e37be748f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c4761165b18e469a912719e696833825b422369bd2e19e124ee4e41e37be748f","first_computed_at":"2026-07-05T11:20:15.297478Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:20:15.297478Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lKHZEvDiFT+NVh/GWHW6wPjhqMt4I6o35B4WqXgJJ25yH2mThJeWThUynivRV5qNYQ5+bpYktobBNjXH38zoDA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:20:15.298037Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.10021","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4931668a0e0c062a2f02b71d8a14d7268bf2dc96fa5f96405e9e6b981348e231","sha256:76b3af85b31aed61a7cba6edbb736d072c3eb1827e9b9987c8cb84c04323a607"],"state_sha256":"981c1c17aa8776459b61511782a6ee619ffaf7a28583031cc9b8f931223ea018"}
