Coding Agent

Build and maintain software in the web workspace or your local terminal.

Describe a change, give the agent the project context it needs, and review the code and evidence it produces. pre.dev supports new apps, existing repositories, planning, implementation, browser verification, and publishing.

How a change moves

1. You describe the change in the web workspace or the CLI: the behavior you want, the context, and the constraints.
2. The agent picks an approach. It answers a question, changes the code directly, or plans a larger task first. Ask for a plan in your message when you want to shape requirements and architecture before it builds. See how the agent works.
3. It builds on the session’s branch. Every session has its own branch. Sprints set the scope of the work, and effort sets its depth.
4. It verifies the work. An independent judge scores each acceptance criterion from the recorded run, and the agent fixes what is unproven. See verification.
5. You review and ship. Read the diff, the verification result, and the preview, then merge through a pull request or publish the app.

Make the first request useful

Give the agent an outcome it can implement and you can verify:

Add assignee and status filters to the issue board.
Keep the existing card layout. Filters should work together,
and an empty result should offer a way to clear them.

For existing code, include what happens today and what should change. For a new app, start with one working flow before expanding the scope.

Choose your workspace

Surface	Best starting point
Web	Create a project, import GitHub code, review plans, preview, and publish
CLI	Work directly in a local checkout and review changes with your usual Git tools
Architect API or MCP	Generate specifications for another development workflow

The web and CLI share project records, planning artifacts, and account settings where supported. A session can run on your laptop through the CLI or in the cloud; see sessions.

Build your first project

A short web workflow from prompt to review.

Use your terminal

Install the CLI and start in a local repository.

Decisions, sprints, and effort.
