Moldable Development: Programming Through Custom Tools
summary
Argues that programming shifts when tools become editable code and shows concrete tooling work: instrumenting databases and parsing homegrown Excel/XML to build a data-lineage viewer that reveals 600 used / 900 unused attributes and uncovers an unknown black‑box step; interactive demos in Glamorous Toolkit raise the abstraction for COBOL BMS screens, trace overlapping variables, wrap an OpenAI tokenizer into live visualizations and construct a back-in-time debugger from token-merge objects.
