## The problem

AI coding agents are fast and unreliable in the same breath. Left alone they drift from conventions, repeat mistakes and produce changes nobody has read.

The speed is only worth having if the output holds up in production.

## What it does

1. **Skill files**: Written conventions for each kind of task, so agents work the way the studio works.
2. **Subagents**: Narrow agents for research, implementation and review, each with a focused brief.
3. **Parallel worktrees**: Independent changes run side by side in separate git worktrees, so they don't collide.
4. **Human review**: Nothing merges without a person reading the diff. Agents draft; the studio ships.

## How it's built

### On Claude Code

Built around Claude Code's skills, subagents and worktree support.

### Used on every build

Client projects and Labs products both run through it, which is how a Pilot Sprint lands in weeks.

## What's next

- Deciding whether to open-source it.
- Writing up the workflow in the Studio Log.
