JevGate

JevGate is a code-review gate. It asks small, precise questions about your code and turns the answers into findings you can act on.

JevGate parses your repository locally and builds small units of evidence: a function, a file outline, a pair of copies, a test, a documentation section. It asks TypeSafe Jev short, typed questions about each one. Code, not a chat model, combines the answers into a verdict. Each finding has a location, how often findings like it were right and a concrete next step, so an agent or CI job can act on it and a person can check it quickly. By default the gate fails only on the rules and levels measured right at least 80% of the time on projects JevGate was never tuned on: among the default rules, function-simplification reviews, right 20 of the 23 times they were labeled there (87%), and 80 of 93 times on 27 more public projects (accuracy).

Review (2):
  src/billing/invoices.ts:88 [maintainability/shared-logic] `createInvoice` and `createReceipt`
    may repeat one piece of logic, so a change to it would have to be made in each place.
    Not yet measured.
    → Keep the logic in one shared function, or dismiss this finding with a reason if the
      copies must stay separate
  src/api/search.py:41 [security/injection] `search_orders` places its parameters into a
    database query without binding, escaping or checking them; a caller passing outside
    input would make it exploitable. Not yet measured.
    → Pass the values as bound query parameters

Where to start

• Install and follow the quick start: a dry run shows exactly what would be uploaded, free and offline.
• What it finds and the rules reference describe every rule and the question it asks, and each rule’s page shows findings it got wrong.
• Accuracy gives how often each rule was right on projects JevGate was never tuned on, and how that is measured.
• Continuous integration sets JevGate up on pull requests with the GitHub Action or any other CI.
• Git hooks run the same gate before each push or commit, and let the change through, saying so, when JevGate cannot finish.
• How it works explains the evidence units and how code, not a chat model, turns answers into findings.
