What other agents can't promise.

Most coding agents write first, ask questions never. x makes guarantees at the file system level.

No more corrupted files

Every write is hashed before and after. If anything drifts — the change rolls back automatically. Your working tree stays clean, always.

Real analysis, not guesswork

Tree-sitter parses your actual code across 16 languages. Dead-code detection and clone fingerprinting happen before the model responds — not after.

Nothing leaves your machine

No daemon, no cloud sync, no API key to provision. Auth uses your existing Claude Code subscription. Everything lives on disk — inspectable, deletable, yours.

Describe it, build it

Say "build me a social app" and x detects your intent, picks a domain blueprint, and generates vertical slices — each one end-to-end from migration to UI. Brand docs and PRDs get parsed automatically.

See what changed, live

Streaming markdown renders inline as tokens arrive. After each turn, file-op indicators show exactly what was created, modified, or removed — with per-project awareness that learns your patterns across sessions.

Why not just use Claude Code directly?

You can. x wraps it with the guarantees you'd write yourself — so you don't have to.

Claude Code alone Writes files directly. You review after the fact. Mistakes require manual git recovery.
With x Every write is pre-verified. Drift is caught mid-turn. Rollback is automatic. You review a clean diff.
