| Anyone makes an agent by describing it: one box drafts the whole agent (name, job, responsibilities, voice, skills to keep, integrations it needs, model limits and budget) as a card to change and try in a chat beside it before creating it, and an agent changes later by saying what to change, shown as a diff before it's saved. Members can make personal agents, which only they talk to and which spend from their own budget, unless owners turn that off; owners promote one to a workspace agent. The agents guide says how. | 1 | /** |

| Money is written one way. A single formatter turns millionths of a dollar into dollars, rounding half up on whole micros rather than on a float, so the same sum reads the same on every page: under a cent reads <$0.01 on a total and exactly nothing is $0.00, while the statement's lines, a session's receipt, the price book and an agent's effort costs carry up to four places where the fraction of a cent is the point; the six formatters that each rounded their own way are gone. This month is the calendar month in UTC from its first day to today everywhere, and billing counts the month's not-yet-closed usage in any range that reaches into the current month, so the top bar's pill, Spend, Home and Usage ask for the same days and get the same figure; Home now reads the usage report the others read instead of adding up statements. Usage's pending sentence says what of that usage the close will charge after the discount and included usage, which the billing API returns as pending_charged_micros. A reconciliation test holds the pill, Spend, Home and Usage to one number for one month. The usage and billing guide says how amounts are written and what this month means. | 11 | import { wholeDollars } from "./money.ts"; |
