 # Implementation Plan: Expanded Test Coverage and Stress Testing
 
 ## Phase 1: Tool Accessibility and State Unit Tests
-- [ ] Task: Review current tool registration and disabling logic in `src/mcp_client.py` and `src/api_hooks.py`.
-- [ ] Task: Write Tests: Create unit tests in `tests/test_agent_tools_wiring.py` (or similar) to verify turning a tool off removes it from the agent's available tool list.

+- [~] Task: Write Tests: Create unit tests in `tests/test_agent_tools_wiring.py` (or similar) to verify turning a tool off removes it from the agent's available tool list.
 - [ ] Task: Implement: If tests fail due to missing logic, update the tool filtering implementation to ensure disabled tools are strictly excluded from the context sent to the provider.
