One continuous workflow
Four modes. One repo-aware loop.
Switch modes depending on whether you need a brief, a patch, a diagnosis, or a controlled execution run.
Plan mode Live in the repo
Turn a vague request into an implementation brief you can actually trust.
Playground starts by shaping the work: milestones, risks, acceptance criteria, and where the patch should land.
Deliverable
Milestone plan ready for approval
A clean handoff for you or the agent to execute next.
- Break work into reviewable steps
- Surface compatibility risks early
- Write success criteria before mutation

const plan = await playground.plan({
goal: "Ship audit logs for sensitive account actions",
output: "milestones + tests + rollout notes",
constraints: ["backward compatible API", "no schema drift"]
});Beyond the answer box
Playground stays in the workflow.
Keep your favorite tools for ideation. Use Playground when the work needs a real plan, repo context, and a controlled path from request to tested patch.
