Jev Selects Claude Code Rules

Jev reads each Claude Code prompt and selects which of 12 project rules apply. The author says a focused session uses about a quarter of the context tokens.

I put Jev inside Claude Code. Jev reads every prompt and picks which of my rules apply. 12 rules in the project, Claude gets the 1 it needs, and a focused session uses about a quarter of the context tokens. Watch: my prompt never mentions payments, yet the payments rule lands the moment Claude edits a checkout file. 40 seconds, real session. The problem: rule files pile up. Test the payment code.

When Claude edits a checkout file, Jev applies the payments rule even though the prompt does not mention payments. The author notes that rule files can pile up and asks viewers to test the payment code.
