Operator v1

Describe an outcome.
It ships the PR.

Operator is the autonomous agent at the heart of Kaer. It plans, branches, edits, runs and ships — in parallel, in isolation, with checkpoints you control.

Reads before it acts

It reads your code.

Before touching a line, Operator maps your project — files, symbols, blast radius. Edits land behind stable anchors, never silent rewrites, so every diff is one you can actually review.

  • Patches by anchor — never rewrites the wrong file
  • Unified diffs with the reasoning attached
  • Impact analysis before every edit

Parallel by default

One prompt, a tree of work.

A single request fans out into subtasks — schema, interface, tests — each running on its own isolated microVM. Operator stitches the results into a single, reviewable PR.

  • Isolated microVMs per subtask
  • Pause, redirect, or take the cursor at any point
  • Checkpoints before anything risky

you are.

No credit card. No queue. Just a prompt — and an agent that actually does something with it.
