05 / Handoffs
Spec
A document describing a piece of work too large for one session: what is being built and why, not the step-by-step of how. Made up of tickets.
How you’ll hear it
“What exactly are we building?”
“It is in the spec. Every session works from that.”
Avoid
Starting multi-session work with no written goal.
The longer version
A spec describes work too big for one session: what is being built, why, and what done looks like. It keeps many sessions, and many people, pointed the same way.
