Score: 7.3/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 6)

Nodecode is a Common Lisp-based AI agent that modifies its own running program via a single `eval` tool, persisting each new definition as a git-committed file so capabilities like PDF reading can be added on the fly. It stands out for live self-updates without restarts, a cell-based extensibility model, and claimed major token-efficiency gains on ARC-AGI-3 benchmarks.

Target audience: AI/agent developers, Lisp enthusiasts, power users seeking extensible coding agents
