Copy and paste
Works today, with every assistant
The manifest page has a button that copies the whole brief as plain text: every account, its exact scope, the free allowance, and the checks the finished build has to pass. Paste it into Claude Code, Cursor, a Jarvis of your own, or a text file. Nothing about this depends on us being clever.
It is deliberately the primary route rather than a fallback. A plain-text brief works in an assistant that does not exist yet, which no integration can claim.
