The thesis: a good tool disappears into the background; the toolmaker's job is *good defaults* that do the thinking once so a thousand users don't each re-derive it, with escape hatches reserved for the genuine minority.\n\narchy's job is an inversion of that essay: **archy exists to make the invisible visible** (coupling, cycles, duplication, drift).

The 2026-05 agent-loop test showed agents sometimes read `archy.yaml` + `CLAUDE.md` directly instead of calling the tools, so contract feedb",
