Moldable Development: programming through custom tools
summary
Argues that programming shifts when tools become code and shows Glamorous Toolkit (gtoolkit.com) used to build problem‑specific tools on demand. Demonstrations include reconstructing a retailer’s DB migration by parsing unstructured DB logs, IP→app mappings and partial sources to reveal unexpected app clusters that change the migration plan, debugging an editor bug by inspecting Rust internals (intervals 0–38 makes the off‑by‑one obvious), and using tests that return live objects for evidence‑based conversations. Claims this yields thousands of per‑system custom tools and faster, cheaper investigation.
