Building an inbox filter with Jev: splitting "urgent" into answerable questions
Jack Cheng built a Jev email filter by breaking "urgent" into concrete questions, then ran it over 90 days of email so older messages still awaiting replies resurfaced.
Pro tip: Point Jev at your inbox. @jackcheng built a Jev email filter, and the first version flagged every newsletter as urgent. He didn’t want that, so he revised the criteria with his agent: Did a human write this? Is someone I know waiting on me? Would ignoring it cost me anything? When he ran those checks across 90 days of email, older messages that still needed a reply floated back up. To build your own version: 1. Give your coding agent TypeSafe’s official skill: https://github.com/typesafe-ai/skills 2. Show it examples you’d select, reject, or hesitate over. Ask it to define what “urgent” means to you. 3. Turn that definition into separate questions Jev can assess. Specify what counts as yes or no and how to combine the results. 4. Test on a small set you’ve already judged, without giving Jev your answers. Investigate disagreements, revise the checks, then test on fresh examples before processing everything. Save the questions and examples that work. You can reuse—and improve—your definition with the next batch.
