People are not the only consumers of an interface anymore. An agent
may need to find a record, compare options, change a setting, or recover
from an error.
Can it do that from the information your product actually
exposes?
/carbon-agentic evaluates agent readiness for websites,
APIs, and tool interfaces. It is not an evaluation of the underlying
model. It examines the product an agent is trying to use.
Try the task before
reading the answer
A browser agent should first attempt a representative goal using its
available page information and controls. An API client needs the
relevant contract and documentation. Giving either one privileged source
knowledge changes what the attempt establishes.
The investigation can then inspect semantics, labels, structured
content, contracts, state, and recovery to explain the friction. A
discoverable button is useful. A reliably understood consequence is more
important.
Include a recovery path
/carbon-agentic evaluate whether a browser agent can find and export a synthetic report; include an expired-session recovery path
The report separates discoverability, comprehension, task operation,
and safety. It should verify actual outcomes rather than treating a
success toast as sufficient evidence.
Emerging protocols and guidance need current source checks. Optional
markup conventions are not universal requirements, and an accessibility
or SEO pass does not establish agent task success.
The useful result is specific: which information was missing, where
the task broke, and what interface change could make it safer and more
reliable.
Agent-friendly should mean easier to use correctly, not easier to
perform consequential actions without permission.
