Environment Variables

Tools

Six questions about any system, plus a render tool. Every tool takes source (EN code or .en/.txt file path). Tool names are shorthand, not specs — read each description before calling; compose and equivalent are mode-based, not general analyzers.

EN Syntax

One statement per line:

actor do: action needs: input1, input2 yields: output1, output2

Shared names between yields and needs create connections automatically:

customer do: place order needs: menu yields: order
kitchen do: prepare food needs: order yields: meal
waiter do: deliver needs: meal yields: served customer

Modeling

Shortened. The full README is on GitHub.
