How add works · one employee, start to finishDaniel,day one to last day.
01
day one · he joins
Daniel connects his tools.
Slack, GitHub, docs, calendar. Read-only, and he chooses what add may see. From this moment add has the context of what he does.

02
week one · add maps
add learns what he knows.
Every PR he reviews, every thread he settles, every decision he makes. add maps the systems he owns, the calls he made, and the people he deals with.

at regular intervals · add asks
add checks in with him, regularly.
A short call, on a rhythm he sets. It asks only what it couldn't answer from his tools; he talks, add writes, he approves. The gaps in his map come first.
