⚠️Warning

10,000 lines a day from coding agents,

who fixes it?

Без структурных ограждений AI-генерированный код быстро превращается в запутанный клубок технического долга.

🔥

Разрастание функциональности

AI-агенты создают дублирующие утилиты и игнорируют существующие паттерны, раздувая кодовую базу.

→ negotiate + Skills keep structure consistent

💀

Тихие сбои

Логические ошибки, скрытые глубоко в сгенерированных функциях, которые проходят базовые тесты, но ломаются в продакшене.

→ ATE writes tests and heals failures

🌀

Архитектурный дрейф

Ваша чистая архитектура деградирует, когда AI вставляет код, не понимая границ.

→ Guard enforces boundaries at runtime

↓

Mandu solves this

Основные концепции

Безопасно. Масштабируемо. Структурировано.

📋

Already giving your agent the same instruction for the third time?

One contract file brings types, API, tests, and runtime validation with it. When the agent drifts, Guard stops it at runtime.

🛡️

Clean architecture, fell apart in a week?

Guard enforces layer boundaries, naming, and dependency rules at runtime. Six presets ready — FSD, Clean, Hexagonal, Atomic, CQRS, Mandu.

// layer violation detected

Agent "claude" blocked.

Reason: layer-violation: shared → features

Architecture preserved. ✅

🧩

Архитектура на основе Slot

Изолированные контексты выполнения. Заменяйте части системы, не ломая целое.

🤖

Агент-нативный (MCP)

Создан для Model Context Protocol. Агенты нативно понимают структуру вашей кодовой базы.

🧪

Still writing tests yourself?

ATE auto-generates Playwright specs from your routes. Pick an oracle level (L0–L3, smoke to contract). When a test fails, the LLM suggests a repair diff.

⏪

One click to undo an agent's mistake.

Snapshot with `mandu change begin` before the agent edits. Rollback if it's wrong, commit if it's right. File-level atomic recovery — no branches.

6-line handler, 8-line contract.
