Rebuilding uji

Everything uji does, from startup to the screen, is written in Lua in the uji module tree, and you can replace any file in it. A file at lua/uji/<path>.lua in your config directory or in a pack replaces the built-in module uji.<path>. A module that is a folder, such as uji.agent, lives in lua/uji/agent/init.lua.

A replacement is a whole file. uji loads yours instead of the built-in one, so the easiest start is a copy of the original from the lua/uji folder of the uji source.

For example, ~/.config/uji/lua/uji/prompt.lua:

local M = {}

function M.system(env)
  return "You are a careful coding agent. Work in " .. env.directory .. "."
end

return M
