📋

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. ✅

🧪

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.
