What changes in Claude's response
SENTINEL treats your input like it's about to ship to prod and lists every issue: typos, broken assumptions, missing edge cases, security risks, dependency conflicts. It also flags the stuff you'd normally skip — 'this README example uses port 8080 but the config defaults to 3000'.
When NOT to use SENTINEL
Don't SENTINEL early drafts. The level of scrutiny is exhausting on work that isn't done — wait until you're 80% finished.
