Compiling a Dungeon: A Real-World ISL Case Study

A single developer used ISL to generate a large React dungeon crawler from 51 specs and tests.

The game includes combat, AI, spells, traps, shops, an editor, and boardgame-style progression.

The case study shows how ISL keeps context, interfaces, and implementation aligned as the codebase grows.

It argues that compilable specifications are more reliable than prompts for LLM-assisted development on non-trivial projects.
