Claude Code hides a /hub path for sub-agent boards

TestingCatalog reports that Claude Code carries an unreleased /hub path where Claude itself would run task boards tracking sub-agents. The sighting includes a sample prompt, "Set up a board with my workstreams and active agents," with Claude controlling the board. Per the same report, it's unclear whether the path ties to the "Hub Mode" spotted earlier. Anthropic announced Claude Managed Agents, a suite of composable APIs for building and deploying cloud-hosted agents at scale, on April 8, 2026.
