Sources are checked on a schedule. Each watch uses the slower of its aspect's default cadence and its plan's cadence floor. The watch reports its actual interval. This is scheduled change detection, not a real-time feed.

Unknown means no known value is available for comparison, for example because a subject has no observations or a source does not publish the requested field. Unknown does not mean unchanged. Verification compares the latest recorded observation; inspect its time and source health before relying on it.

Start with a supported package, repository, specification, public page, or status source. Coverage is checked before a watch is created. Private registries, sources behind a login, and sources closed to automated reading are not covered.

A durable cursor lets your agent resume from acknowledged state and read later changes from its active, attached watches. New watches cover future changes only. Webhooks use at-least-once delivery, so consumers should deduplicate using the event's idempotency key.

Free includes one repository and a bounded hosted AI allowance. Pro connects five repositories and Studio connects fifteen. Paid repository work requires your own AI provider; there are no repository AI credit quotas or dependency count limits. World State stays on Since AI with separate watch and monthly verification
