Documentation

README

Excerpt

When to use

Dev asks "are we following the architecture?" or "is this a valid change?"
PR touches files near module boundaries or service interfaces
Weekly architecture health check
Any cross-service import was just added

When NOT to use

"What does module X do?" → use brownfield-chat
"What breaks if I change X?" → use brownfield-chat
Graph coverage is low on a file → use brownfield-fix (it fills gaps before editing)
No PLAN.md exists — drift requires machine-readable boundaries in PLAN.md

This is the opening of the README. Read the full README on GitHub.
