Register — you land on Model connections with a short setup tip.

Under Models, pick a provider and paste your key. Use sk-mock only when the API has MOCK_LLM=true. Pro/Ultra include Bedrock.

Open Mission Control → Load demo for the sample Architect mission (or create your own workspace under Plan).

Pick a model route and click Launch. Work happens in an isolated sandbox; Files rail shows the tree.

Inspect evidence, then Approve changes. Nothing is accepted without you.
