ADR stands for Architecture Decision Record. It's a critical aspect of producing well-designed code using GenAI (in my case I use Claude Code). The idea of an ADR is to capture something platform-sized. Something that improves the overall code base plus the developer and author experience.

Sharpee has it's own home outside of github now. Visit https://sharpee.net/. There are quick start and author guides along with the beta port of Mainframe Zork aka Dungeon. The platform is also in beta and can be used to create stories. I only have the thin

In the last week I've been play-testing the port of Dungeon which has exposed many things about Sharpee and the Dungeon implementation. Many many things. Just the first ten to twenty turns of Dungeon have uncovered a lot of issues. The troll logic is actually quite complicated.

White Paper on Sharpee Interactive Fiction Engine January 2026 Abstract Sharpee's Capability Dispatch system solves a fundamental problem in extensible software: how do you allow third-party code to modify the behavior of standard operations without sub-classing, monkey-patching, or invasive hooks? This paper describes a pattern

Classic IF Systems and Sharpee A detailed comparison of how TADS, Inform 6, Inform 7, Hugo, and Sharpee handle the journey from player input to executed action. Overview All parser-based IF systems solve the same fundamental problem: transform natural language input into game actions. The solutions share common ancestry

In the process of porting Dungeo to Sharpee, we got to a completed implementation, but some unit tests missed important steps. When I started a "walkthrough" test in phases, we discovered a glaring gap in my grammar and parser implementation. I should say fundamental misunderstanding of what the
