CHANGELOG

LibrarianAgent: Introduced a new Librarian Agent that allows testing of an agent's model reading its resources and prompts. This enhances the ability to simulate and audit resource access within the MCP framework.
StorytellerAgent: Added a Storyteller Agent that streams replies in chunks, enabling testing of streamed responses. This feature supports progressive data delivery, improving real-time interaction capabilities.

Feature Flags: Implemented a new app for feature flag management with default gate values, allowing more flexible control over feature accessibility.
Job Hooks: Introduced job auditing capabilities with hooks that record every job attempt, providing detailed insights into job execution and retries.

Tool Command Execution: Resolved an issue where npx commands were not executing correctly on Windows due to shell resolution problems. This fix ensures consistent tool execution across platforms.
