[karmaboy1309]

• Add /health endpoint to agent.py returning comprehensive system, version, Ollama connectivity, and capability diagnostics
• Enhance /status endpoint to indicate agent health status
• Add automated test suite in agent/test_agent.py testing dependencies, endpoints, memory context generation, and note action parsing
• Add 'npm run test:agent' script to package.json
• Add checkAgentHealthDetails in src/services/ollama.ts
• Add interactive 'Check Agent Health' diagnostic panel in AIChat.tsx settings with real-time ping, latency, and status feedback
• Closes The AI agent is not checked that it's working well or not !! #13

agent/agent.py:38

• This probe is hard-coded to OLLAMA_URL, so when the UI's configured aiSettings.ollamaUrl points to a non-default Ollama server, /health reports the default as disconnected even though /chat uses the configured URL. Pass the configured endpoint through the health check (or explicitly probe it in the client) so diagnostics cover the backend the app actually uses.

        r = requests.get(f"{OLLAMA_URL}/api/tags", timeout=1)

agent/test_agent.py:27

• If Flask, flask-cors, or requests is missing, importing agent.agent raises ImportError before unittest can run; this fallback then imports the requested names from agent/__init__.py, which exports none of them. Thus npm run test:agent crashes at module import instead of executing test_required_modules and reporting the missing dependency. Move the dependency check ahead of the agent import or explicitly handle an unavailable agent module.

    from agent import (

• On the fallback path, latencyMs was captured before the direct Ollama request, so the report omits the time spent on the probe it is reporting and can show an outdated/near-zero latency after that request completes. Compute the value after the direct request, or measure that request separately.
