Rewrite if-statements with Jev

Ricky Grannis-Vu on replacing deeply nested boolean expressions with one natural-language sentence for Jev to decide.

@RickyGrannisVu

We rewrote the oldest primitive in programming. The if statement takes a sentence now, and Jev decides. That nested boolean mess eleven rules deep, four AND/ORs, one comment nobody understands anymore? Replace all of it with "if this expense is allowed under the expense policy." Judgment Mode, live now.

everything you need to start building with jev, in one article. code, architecture, diagrams... everything you need to follow the build and make it your own. x.com/i/article/2102…

Build an agentic harness using Jev
Avid’s builder’s guide, and the fullest public write-up of the pattern: where the decision layer sits in a coding harness, the five rules that keep it enforceable, and keel, the Rust app it was built in. Honest about the self-improvement part it has not proved.

The Jev + Claude Code Stack
cyril on where the 200× and 400× headline figures come from and why they are a ceiling rather than a typical result: 31 bounded checks counted in one real session, and the decision-point audit that finds yours.
