At a glance
- Hosted parent agents can launch snapshot-isolated children that read a frozen workspace without modifying files, running commands or affecting the parent.
- Managed sessions created from published AgentDefinitions can load static Skills and pass pinned MCP server and Hook selections to hosted runtimes. File and folder deletion also gains confirmation steps in the Files interface.
Why it matters
For teams evaluating agent tooling, these changes make execution scope and configured integrations more concrete review items. A frozen review workspace can be useful when analysis should not alter the code under examination.
Limits and availability
AISubHub has not installed or tested this release. The notes do not prove every feature is available in every standalone setup, and hosted components may require separate configuration. They establish neither new model access nor free credits, prices or subscription entitlements.
