Round once, on the total.

Some carts were off by a cent. Each line was rounded before tax, so small errors added up.

Rounding rules

Round a monetary amount one time, at the end of the calculation. Rounding in the middle moves the result.

Invoices use half-even rounding. An amount that ends in exactly half a cent goes to the nearest even cent.

See Half-even rounding for the full table.

Run the tax tests

$pnpm vitest run tax-total

The review of the tax path is complete. It has one finding, and a new test fails on it.

What I found

Line rounding: src/checkout/tax-total.ts rounds each line in taxTotal(), then adds the lines. The cart rounds one time, after the sum.

Failing case: three lines of 0.336 give 1.02. The correct tax is 1.01.

Checks run

pnpm vitest run tax-total: 6 passed, 1 failed (the new case).

pnpm tsc --noEmit: passed.

Rounding rules
Round a money value once, at the end of the calculation.
Rounding at every step can move a total by a cent.

A value exactly halfway between two cents goes to the even cent.

Notas de un vídeo
El agente obtiene los pasos, los comandos y las decisiones de un vídeo de YouTube o de una grabación.
Alertas en el móvil
El agente envía una alerta a tu móvil cuando el trabajo termina, falla o necesita tu decisión.

Los vídeos explicativos, la voz y las notas de vídeo usan tu propia clave de API de Gemini. La herramienta del navegador necesita la extensión HB Code Browser Bridge para Chrome. Las alertas en el móvil necesitan el ajuste de notificaciones y un móvil conectado.

Hecho para el trabajo diario

HB Code ejecuta Claude Code con el Claude Agent SDK de Anthropic, y Codex con su propia compilación del Codex app-server de OpenAI. Cada agente conserva su propio historial y su propio inicio de sesión.

Los mensajes esperan al escritorio
Si el móvil no llega al escritorio, tu mensaje espera en el móvil. Sale cuando vuelve la conexión, y un reintento nunca lo envía dos veces.
Continúa una conversación guardada
Inicia una sesión desde una conversación que el agente guardó para la carpeta del proyecto. Con Claude Code, esto incluye las conversaciones de la terminal. Después de un reinicio, cada sesión se abre con su historial completo.
Diez temas de color
Cada tema tiene una versión clara y una oscura. Tus móviles usan el tema que eliges en el escritorio.
Colores de sintaxis en comandos y archivos
Los comandos tienen colores de shell, y un script dentro de un comando recibe los colores de su propio lenguaje. Los archivos se abren con colores de sintaxis y números de línea.
