For Claude Code, in VS Code

The world codes with AI now. Attentry watches the code.

Millions of people ask an agent for an app and get thousands of lines back. Attentry checks every edit for security holes, copied code and dead code, and tells the agent so it can fix them before anything ships.

You ask: "add a coupon code"

The problem

Fast code. Messy code.

The agent writes it in seconds. Nobody reads every line, and the agent never looks back: it doesn't know the repo already had that helper, or that the route it just added lets anyone in.

45%

of AI-generated code samples had a security flaw in Veracode's tests of over 100 models.

Claude writes. Attentry watches. Claude fixes.

Attentry doesn't take the wheel. It points at what's wrong the moment it's written, and the agent cleans it up before you ever see it.

How it works

Four moments. Otherwise, quiet.

When you ask

The code you already have

Claude hears which helpers and routes in the repo match your request, so it plans with them.

Attentry: the repo already has code related to this request: - `timeAgo` in src/utils/time.js:1 - GET /api/rides/:id in server.js:11

Before an edit

No second copy

About to write a function the repo already has? Claude hears where the existing one is.

Attentry: `formatRidePrice`: the repo already has `formatPrice` (src/utils/money.js:2). Import it.

After an edit

Only what this edit added

New problems, once each, in a few lines. A clean edit gets nothing at all; old issues never nag.

Attentry: this edit added 1 problem: socket event "message:delete" loads a record by an id the caller sends without checking it belongs to the caller

At the end

A change card for you

What changed, what it added or fixed, and whether the tests passed. Ten seconds to read.
