- 22 unit test files added/modified across all core modules
- Fix jsonschema ValidationError import in test_tool
- Coverage increased from 23% to ~35% overall
- Replace LocalShellComponent's one-shot subprocess.run() with a
PersistentShellSession that wraps a long-running bash process per UMO.
cd/export/source now persist naturally within a conversation.
- Support background task execution via nohup.
- Remove unused ToolSessionManager / ToolSessionState (dead code,
never wired to any consumer).
- Fix performance benchmark: separate throughput and memory measurement
so tracemalloc doesn't distort timing (was 7x slower).
- Optimize bool validation in CommandFilter with frozenset + isinstance
short-circuit.
Introduce session-level state management for tools that need to maintain
state across conversation turns within the same session (UMO).
- Add ToolSessionManager class for central per-(UMO, tool_name) state
- Add ToolSessionState with set_persistent(key) support
- Add is_stateful flag to FunctionTool base class
- Wire session_manager through run_context in all agent runners
- Update ExecuteShellTool to use framework session manager
- Update CLAUDE.md with stateful tool documentation
BREAKING: Tools that were manually managing session state via _sessions
dict should migrate to use the framework's ToolSessionManager for proper
lifecycle management and persistence support.
* stage
* refactor: 重构 Function Tool 管理并引入 multi agent handsoff 机制
- Updated `star_request.py` to use the global `call_handler` instead of context-specific calls.
- Modified `entities.py` to remove the dependency on `FunctionToolManager` and streamline the function tool handling.
- Refactored `func_tool_manager.py` to simplify the `FunctionTool` class and its methods, removing deprecated code and enhancing clarity.
- Adjusted `provider.py` to align with the new function tool structure, removing unnecessary type unions.
- Enhanced `star_handler.py` to support agent registration and tool association, introducing `RegisteringAgent` for better encapsulation.
- Updated `star_manager.py` to handle tool registration for agents, ensuring proper binding of handlers.
- Revised `main.py` in the web searcher package to utilize the new agent registration system for web search tools.
* chore: websearch
