How the agent did it
- The author designs the tool and playtests the supported games.
- The tool decompiles Sierra resource files and identifies unwinnable states.
- It generates preventive code and emits loose game patch files.
The author is building Lucasartsifier to prevent situations in Sierra adventure games where a player discovers too late that an essential item was left behind. They describe dividing the work with Claude: the human handles design and playtesting, while Claude does the rest.
The resulting tool decompiles Sierra resource files, uses static analysis to find these unwinnable states, generates code that prevents players from entering them, and emits loose patch files. Players place those files alongside the original game resources. The author says the analysis uses generic logic rather than game-specific code, although supporting additional games requires engine work for newly encountered idioms and mechanics.
The post gives Leisure Suit Larry 2 as a concrete example. Its patched version stops the player boarding the cruise ship without both sunscreen and the Grotesque Gulp, avoiding a later death on the raft. The author reports working support for Leisure Suit Larry 2, King's Quest 4, King's Quest 6, and Laura Bow 2. King's Quest 5 remains in progress.
Who it's for: Developers interested in using an agent to implement analysis tools while retaining responsibility for design and hands-on gameplay verification.

Frequently asked questions
How are the generated patches installed?
The tool emits loose patch files that can be placed alongside the game's original resource files.
Does every supported game need its own custom logic?
The author says the logic is generic and contains no game-specific code, but each newly supported game requires engine work to handle additional idioms and mechanics.
