Models and tools come and go; the way good engineers actually work, planning, reviewing, debugging, reading the source, does not. Waza turns those habits into eight skills that run on whatever agent you have, so your workflow never depends on a single model staying available.
The fashionable move is to bolt on a pack of "superpowers", dozens of skills promising an agent can suddenly do anything. But unconstrained capability is the problem, not the cure: it drifts into confident, generic, subtly wrong work. Waza adds no new powers. It encodes the habits a good engineer already has, so the model spends its capability on precision instead of breadth. Eight skills, not eighty, the few that actually decide quality, each carrying reference docs and real-failure gotchas rather than a one-line promise that rots the moment a task gets specific.
