When GreatCTO detects pack-specific signals in your repo (e.g. twilio in deps, SaMD in README), it auto-attaches the pack — adding specialist reviewer agents, human gates, threat-model templates, and EVAL suites on top of your base archetype pipeline.
npx great-cto init scans your repopackages/cli/src/packs.ts matches stack signals + README terms.great_cto/PROJECT.md as packs: voice-pack, clinical-pack/inbox for your sign-offOverride anytime by editing packs: in PROJECT.md or running /migrate.
