-## 1. Introduction - -This document provides a detailed analysis of the AI chat implementation within the `core-api` service, focusing on the integration of Google's Agent Development Kit (ADK), LiteLLM, and Ollama. The primary goal is to understand the current architecture, identify probable causes for production failures, and propose actionable improvements to enhance stability, maintainability, and performance. - -## 2. Current Implementation Analysis - -The `core-api` service employs a sophisticated but complex dual-path architecture for handling chat completions. - -### 2.1. Dual-Path Architecture - -Two distinct endpoints process chat requests: - -1. **Agent-Based Path (`/api/v1/ai/chat/completions`):** Managed by `src/controllers/ai_controller.py`, this is the primary, advanced endpoint. It leverages an agent built with the Google ADK for complex logic, including tool usage. If the agent is unavailable or fails, this endpoint critically falls back to the direct path. - -2. **Direct Ollama Path (`/api/v1/chat/completions`):** Defined in `src/api/v1/chat.py`, this endpoint provides a simpler, OpenAI-compatible interface that interacts directly with Ollama, bypassing the agent. - -This dual-path system, especially the silent fallback in the main controller, creates ambiguity and can mask critical failures in the agent stack. - -### 2.2. ADK and LiteLLM Integration - -The core of the agent is in `src/agent/orchestrator.py`. - -- It uses `google-adk` to define the agent's structure and logic (`UnifiedAgent`). -- It uses `litellm` as a compatibility layer to connect the ADK to the Ollama backend. The agent is instantiated on a per-request basis, making it stateless from the ADK's perspective. -- **Crucially, the connection to Ollama is configured via the `OLLAMA_API_BASE` environment variable.** - -### 2.3. Configuration Management - -Application settings are centralized in `src/config.py` and loaded from `.env` files. However, a critical inconsistency exists: - -- The **direct Ollama client** (`src/models/ollama_client.py`) correctly uses the `ollama_base_url` setting from the `Settings` object. -- The **ADK/LiteLLM agent** (`src/agent/orchestrator.py`) ignores this and relies exclusively on the `OLLAMA_API_BASE` environment variable. - -This discrepancy is a primary source of configuration fragility. - -### 2.4. Production Environment - -The `Dockerfile` defines the production container. It installs dependencies from `requirements.txt` (including `google-adk` and `litellm`) but **does not set the `OLLAMA_API_BASE` environment variable.** This means the agent defaults to LiteLLM's hardcoded `http://localhost:11434`, which may not be correct in all deployment scenarios. - -The Docker `HEALTHCHECK` only tests the direct Ollama client via `/health`, meaning the service can report as healthy even if the entire agent stack is non-functional. - -## 3. Potential Causes of Production Errors - -The investigation points to several likely causes for the reported failures. - -1. **Configuration Mismatch (Most Likely Cause):** The agent is likely failing because the `OLLAMA_API_BASE` environment variable is not set or is set incorrectly in the production environment. Because the direct client uses a different configuration variable (`ollama_base_url`), the fallback mechanism works, and the API returns a successful response, completely hiding the agent's failure. Developers may be unaware that the agent is not being used. - -2. **Silent Agent Failure:** The fallback logic in `ai_controller.py` prevents any errors from the agent from propagating. While this ensures availability, it makes debugging impossible and hides the fact that advanced features (tool use, complex reasoning) are not executing. - -3. **Incomplete Health Check:** The current health check provides a false sense of security. The service can be "healthy" while the core agent functionality is broken. - -## 4. Suggested Improvements and Optimizations - -To address these issues, the following improvements are recommended: - -1. **Unify Configuration:** - - **Action:** Refactor `src/agent/orchestrator.py` to source the Ollama URL from the central `Settings` object in `src/config.py`. Remove the dependency on the `OLLAMA_API_BASE` environment variable. - - **Benefit:** Creates a single, unambiguous source of truth for the Ollama URL, simplifying configuration and reducing errors. - -2. **Eliminate Redundant Endpoint:** - - **Action:** Deprecate and remove the `/api/v1/chat/completions` endpoint in `src/api/v1/chat.py`. The `ai_controller` should be the sole entry point for all chat-related requests. - - **Benefit:** Simplifies the architecture, removes code duplication, and eliminates confusion about which endpoint to use. - -3. **Improve Health Checks:** - - **Action:** Implement a dedicated agent health check endpoint (e.g., `/health/agent`) that specifically invokes the agent and verifies its connection to Ollama via LiteLLM. - - **Benefit:** Provides a true signal of the agent's status, enabling reliable automated monitoring and faster failure detection. - -4. **Introduce an Explicit Failure Mode:** - - **Action:** Add a configuration flag (e.g., `AGENT_FALLBACK_ENABLED`) that, when disabled in development/testing environments, causes agent failures to return a `500` error instead of silently falling back. - - **Benefit:** Makes debugging the agent significantly easier. - -5. **Explore Stateful ADK Sessions:** - - **Action:** Investigate using the ADK's built-in session management (`session_service`). This would involve creating sessions that persist across multiple requests. - - **Benefit:** Could improve performance by reducing agent initialization overhead and would enable more sophisticated, multi-turn conversational memory within the agent's context. - -## 5. Architectural Review and Validity - -The current architecture is powerful and ambitious. The use of the Google ADK provides a solid foundation for building advanced, tool-using agents, and the Qdrant-based memory system is robust. - -However, its validity is severely undermined by its fragility and opacity. The configuration mismatch and silent fallback mechanism make the system difficult to debug and unreliable in a production setting. The dual-path entry points add unnecessary complexity. - -The architecture is fundamentally sound but requires the recommended refactoring to become robust, maintainable, and production-ready. By unifying configuration, improving observability, and simplifying the request flow, the `core-api` service can reliably deliver on the promise of its advanced agent capabilities. diff --git a/docs/architecture/agent-flow-diagrams.md b/docs/architecture/agent-flow-diagrams.md deleted file mode 100644 index 93d4ba8..0000000 --- a/docs/architecture/agent-flow-diagrams.md +++ /dev/null @@ -1,759 +0,0 @@ -# Agent Architecture Flow Diagrams - -**Date**: 2025-11-23 -**System**: Core API Unified Agent with LangGraph - -This document shows the data flow through the agent system for various scenarios, including which models are used and how components interact. - ---- - -## System Components Overview - -``` -┌─────────────────────────────────────────────────────────────────┐ -│ Open WebUI │ -│ (or any OpenAI client) │ -└────────────────────────┬────────────────────────────────────────┘ - │ POST /v1/chat/completions - │ - ▼ -┌─────────────────────────────────────────────────────────────────┐ -│ Core API (FastAPI) │ -│ ┌──────────────────────────────────────────────────────────┐ │ -│ │ AI Controller (ai_controller.py) │ │ -│ │ • Routes all requests to unified agent │ │ -│ │ • Converts OpenAI format ↔ agent format │ │ -│ └─────────┬────────────────────────────────────────┬───────┘ │ -│ │ │ │ -│ │ │ │ -└────────────┼─────────────────────────────────────────────────────┘ - │ - ▼ - ┌──────────────────────┐ - │ Unified Agent │ - │ (orchestrator.py) │ - │ • LangGraph ReAct │ - │ • mistral:7b │ - │ • Tool calling │ - │ • Decides: tools │ - │ or direct answer │ - └──────────┬───────────┘ - │ - ┌──────────▼───────────┐ - │ Agent Tools │ - │ (tools.py) │ - │ • Infrastructure │ - │ • Web scraping │ - │ • Documentation │ - └──────────────────────┘ -``` - ---- - -## Scenario 1: Simple Knowledge Prompt (No Tools Needed) - -**User**: _"What is Docker?"_ - -``` -┌──────────┐ -│ User │ "What is Docker?" -└────┬─────┘ - │ POST /v1/chat/completions - │ - ▼ -┌────────────────────────────────────────────┐ -│ Core API - AI Controller │ -│ │ -│ 1.

Regular gemma3 models (4b, 12b) do NOT have tool support, regardless of size. - -## Why Size Doesn't Matter Here - -In a cloud/API context, you'd want the smallest model possible to reduce costs. But in our homelab: - -### Our Context: -- **Free inference** (running locally on Ollama) -- **GPU available** (RTX 2080 Ti with 11GB VRAM) -- **Single user** (no concurrent load) -- **Quality > Speed** (correctness matters more than 500ms latency) - -### Trade-off Analysis: -``` -gemma3-tools:1b savings: -- Memory: 6.5GB saved (we have 11GB available, not constrained) -- Speed: 500ms faster (2s → 1.5s, marginal UX improvement) -- Cost: $0 saved (local inference is already free) - -mistral:7b benefits: -- Reliability: 100% vs 33% success rate (CRITICAL) -- Tool selection: Correct tool vs wrong tool -- Response quality: Natural synthesis vs confused output -``` - -**Conclusion**: The savings don't justify the reliability loss. - -## Integration Test Results - -### Discovered During Testing - -Our current implementation already handles the case correctly: - -**File**: [services/core-api/src/agent/orchestrator.py](../../services/core-api/src/agent/orchestrator.py:36-40) - -```python -# The agent model must support tool calling -self.llm = ChatOllama( - model=self.settings.agent_model, # mistral:7b - base_url=self.settings.ollama_base_url, - temperature=0.7, -) -``` - -The agent is hardcoded to use `agent_model` from config (currently `mistral:7b`). This is correct because: - -1. **Tool calling is a requirement** - The agent uses `create_react_agent` which requires tool support -2. **Not all models support tools** - As demonstrated by phi3:mini -3. **Quality matters** - gemma3-tools:1b technically works but unreliably - -## Recommendations - -### Short Term (Current Implementation) ✅ - -**Keep using mistral:7b** for the agent orchestrator: -- Proven reliability -- Excellent tool calling support -- No resource constraints in homelab environment - -### Medium Term (Monitoring) - -**Watch for**: -- Ollama releases of newer tool-capable models (e.g., `llama3-groq-tool-use`) -- Gemma4 or Phi4 with improved tool calling -- Qwen2.5 variants (some support tools) - -**Test criteria for replacement**: -- 100% success rate on tool calling tests -- Correct tool selection (not just "can call tools") -- Consistent response format -- Production-ready error handling - -### Long Term (Optimization) - -**If memory becomes a constraint**: -1. Test `gemma2:9b` - Larger than 1B, might have better tool support -2. Test `qwen2.5:7b` - Similar size to mistral, different architecture -3. Consider quantization of mistral:7b (Q4 or Q5) to reduce memory footprint - -**If latency becomes critical**: -1. Upgrade GPU (RTX 4070+ for faster inference) -2.

Start a conversation: "Hello, testing Phase 1" -7. Verify response arrives -8. Try streaming: Should see tokens appear one by one - ---- - -## Success Criteria Checklist - -### Code Quality -- [ ] All Python files have proper imports -- [ ] No syntax errors -- [ ] Type hints where appropriate -- [ ] Docstrings for functions -- [ ] Logging configured - -### Functionality -- [ ] Health endpoint returns 200 -- [ ] Models endpoint lists available models -- [ ] Non-streaming chat works -- [ ] Streaming chat works -- [ ] Model aliases resolve correctly -- [ ] Error handling works (try invalid model name) - -### Docker -- [ ] Image builds successfully -- [ ] Container starts without errors -- [ ] Container passes health check -- [ ] Can connect to Ollama from container -- [ ] Logs are readable - -### Integration -- [ ] Open WebUI can connect -- [ ] Can send messages through orchestrator -- [ ] Responses appear in Open WebUI -- [ ] Streaming works in UI -- [ ] No regressions from direct Ollama connection - ---- - -## Troubleshooting - -### Issue: "Ollama connection failed" - -**Symptoms:** Health check shows `ollama_connected: false` - -**Solutions:** -1. Check Ollama is running: `docker ps | grep ollama` -2. Check network connectivity: `docker exec ai-orchestrator curl http://ollama:11434/api/tags` -3. Verify both containers on ai-dataplane network -4. Check Ollama logs: `docker logs ollama` - -### Issue: "Model not found" - -**Symptoms:** Error when trying to use a model - -**Solutions:** -1. List available models in Ollama: `docker exec ollama ollama list` -2. Pull missing model: `docker exec ollama ollama pull gemma:7b` -3. Check model aliases in config.py -4. Verify model name spelling - -### Issue: "Streaming not working" - -**Symptoms:** No streaming output, or all text arrives at once - -**Solutions:** -1. Check Content-Type header: Should be `text/event-stream` -2. Verify stream=true in request -3. Check browser/client supports SSE -4. Test with curl first (easier to debug) - -### Issue: "Open WebUI can't connect" - -**Symptoms:** Open WebUI shows connection error - -**Solutions:** -1.

Make Your Changes - -Edit agent code, tools, prompts, etc. - -### 3. Run Tests Again - -```bash -python tests/test_ai_flow_quality.py -``` - -### 4. Compare Reports - -Compare the new report against the baseline: - -```bash -# List recent reports -ls -lh tests/reports/ - -# Compare two reports -diff tests/reports/quality-report-20251201-103045.txt \ - tests/reports/quality-report-20251201-115522.txt -``` - -**Key metrics to watch**: -- Pass rate (should stay 100%) -- Average response time (should not significantly increase) -- Individual test failures (investigate immediately) - -### 5.
