Nodecode, an agent written in Lisp that evolves.

Updates while it runs

An orchid opens new flowers while it keeps growing. Nodecode makes its updates on the fly and the program evolves naturally.

Everything is a cell

A cell is like a folder that teaches Nodecode something new: a provider login, a tool, a skill, a GitHub repo, a MCP server, you name it.

/evict, no more /compact

Compaction rewrites older turns into a summary and loses the detail. Eviction moves them to the log whole, and every word can be read back. Accuracy holds: a new paradigm for long sessions.

Lisp

Lisp evolves its own language: code is data, so a program can rewrite itself while it runs. Nodecode redefines itself on the fly.

Cells, the building blocks of the organism.

One form declares a cell: its settings, tools, commands and hooks.
