You changed sign-in. You did not ask for a company-wide quality
audit.
This sounds obvious until a testing agent spends its time
investigating the homepage while the new password-reset flow remains
untouched. More activity is not necessarily more useful testing.
/carbon-test gives CARBON a specific target: a feature,
journey, API, component, or behavior. You can name the quality concern
too. “Checkout accessibility” is a different assignment from “checkout
pricing.”
Follow the behavior
across its boundary
Focused does not mean superficial. A password-reset change may
involve an email link, an expired token, two browser tabs, and the
account's existing sessions. Those are relevant neighbors of the
behavior, not an excuse to test everything.
CARBON uses the available requirements, code, validation rules, and
current interfaces to select cases. It can combine live interaction with
source inspection, then preserve which conclusions came from which
evidence. If you ask about a screenshot alone, it cannot claim the reset
link actually worked.
The result is a scoped report: what was attempted, what happened,
what needs fixing, and what remains outside the investigation. That
boundary is useful. It tells the next person what they can rely on.
Give the command a real
assignment
/carbon-test password reset; check expired links, repeated use, and keyboard recovery; use synthetic accounts and ask before sending email
The practical advantage is the short path from a change to relevant
evidence. You do not need a fresh testing project every time a small
feature moves. You need a clear question and an investigation that stays
with it.
Small scope. Serious testing.
