What
When Claude Code reads an artifact (a file-like object it can boot up and inspect), the internal boot function now accepts a probeToolUseId. For plain status-probe reads, it checks a cache of recent probe results keyed by the artifact's slug (short identifier); if the same tool call already probed that artifact recently and the cached version isn't stale, it reuses that result instead of fetching again.
Why
This avoids redundant network fetches when the same artifact is checked more than once within a single tool call, making artifact reads faster and less wasteful.
