then let a dozen of them run at once

Ensemble maps how your codebase actually connects, so you can start a task from any file, module or function. Build your own agents out of skills you can read, decide which one gets which job, and run them all at once.

Every agent aimed at a part of the map. Every skill visible before it runs.

THE IDEA

YOUR AGENTS. YOUR CODE. SIDE BY SIDE.

Coding should feel like directing, not babysitting. Everything here is built to be pointed at, read and understood before it runs.

COMPOSE YOUR OWN AGENTS

Build an agent from skills, tools and a model, name it, and keep it. A reviewer, a test-writer, a refactorer — shaped the way you work, not the way a vendor guessed.

DECIDE WHICH AGENT GETS WHAT

Route every task to the agent that suits it, and hand it to a different one mid-run. No single generalist doing everything a little bit badly.

SKILLS YOU CAN ACTUALLY READ

Open any skill and see what it does, what it is allowed to touch and when it fires. No black box, no guessing why a run went sideways.

START FROM ANY PART OF THE MAP

A live map of how your codebase connects. Click a file, a module or a function and start the task right there, with the context already loaded.

STOP BABYSITTING.START DIRECTING.

the fun part of coding, back where it belongs
