“The blueprint should EXTEND it, not duplicate it.”

The request was to design a unified plugin catalog. The blueprint process starts with impact analysis — which is how the model found the catalog before anyone described what it should contain.

Major finding before scope confirmation: the canonical catalog you wanted to "build" already exists at `packages/shared/src/constants/plugin-catalog.ts` — 16 features, tier-gated, with `implementedBy` linking to plugin/skills/hooks. The blueprint should EXTEND it, not duplicate it.

No prompt asked it to check for prior art. The process did. The most common failure mode of AI-built features — a second, slightly different copy of something that already works — got caught before a line was written.
