## Phase 1-6: Foundation (Original Plan)

### Phase 1: Tool Infrastructure ✅ Complete

| Component | Status | Notes |
|-----------|--------|-------|
| `BaseTool` abstract class | ✅ | `src/domains/tools/base.py` |
| `ToolResult` dataclass | ✅ | Consistent success/error/truncated handling |
| `ReadFileTool` | ✅ | With line numbers, offset/limit support |
| `GlobFilesTool` | ✅ | Pattern matching, sorted by mtime |
| `GrepContentTool` | ✅ | Regex search with context lines |
| `BashReadOnlyTool` | ✅ | Allowlist-based command filtering |
| `EditFileTool` | ✅ | Find-and-replace with unique match validation |
| `WriteFileTool` | ✅ | Create/overwrite files with size limits |
| `BashTool` (full) | ✅ | Write-enabled shell with safety controls |
| `WebSearchTool` | ✅ | SearXNG integration for web search |
| Path validation | ✅ | `allowed_paths` restriction |

**Status:** Tools honor `.gitignore` patterns and default ignores (`.venv/`, `__pycache__/`, etc.)

### Phase 2: Explore Agent ✅ Complete

| Component | Status | Notes |
|-----------|--------|-------|
| `BaseAgent` abstract class | ✅ | `src/domains/agents/base.py` |
| Agent registry | ✅ | `register_agent()`, `get_agent()`, `list_agents()` |
| `ExploreAgentImpl` | ✅ | PydanticAI-based implementation |
| System prompts | ✅ | Mistral-optimized with tool examples |
| Tool registration | ✅ | `@agent.tool` decorator pattern |
| Sanitized Ollama provider | ✅ | Fixes `content: null` issue |
| Streaming support | ✅ | `run_stream()` method with SSE |

**Available tools:** `read_file`, `glob_files`, `grep_content`, `bash_readonly`, `edit_file`, `write_file`, `bash`, `web_search`

**Gap:** Mistral Nemo sometimes hallucinates instead of using tool results.

### Phase 3: CLI Foundation ✅ Complete

| Component | Status | Notes |
|-----------|--------|-------|
| Typer + Rich setup | ✅ | Standalone `webber-cli/` package |
| `webber-cli --version` | ✅ | Shows version from pyproject.toml |
| Console theming | ✅ | Centralized color palette |
| Markdown rendering | ✅ | Rich markdown output |
| Streaming display | ✅ | Real-time token output with `--stream` flag |

### Phase 4: Agentic Loop ⚠️ Partial

| Component | Status | Notes |
|-----------|--------|-------|
| `webber-cli chat` command | ✅ | Interactive mode with streaming |
| `webber-cli explore` command | ✅ | One-shot query with streaming |
| `SessionState` dataclass | ✅ | Basic context tracking |
| `AgenticLoop` class | ⚠️ | Basic implementation, not fully utilized |
| Conversation history | ❌ | Not persisted between turns in CLI |
| Context management | ❌ | No token counting or summarization |

### Phase 5: REST API ✅ Complete

| Component | Status | Notes |
|-----------|--------|-------|
| `POST /agents/run` | ✅ | Execute agent with prompt |
| `POST /agents/stream` | ✅ | SSE streaming responses |
| `GET /agents/` | ✅ | List available agents |
| `GET /agents/{name}` | ✅ | Get agent info |
| Request/response schemas | ✅ | Pydantic models |

### Phase 6: Polish & Tests ✅ Complete

| Component | Status | Notes |
|-----------|--------|-------|
| Tool unit tests | ✅ | 109 tests total |
| API endpoint tests | ✅ | 11 tests for agent routes |
| Health check tests | ✅ | 2 tests |
| Security tests | ✅ | 14 tests for path traversal, injection |
| Integration tests | ✅ | 10 tests with real LLM (requires Ollama) |
| E2E tests | ✅ | 12 tests against running API server |

## Known Issues

1. **Model hallucination** - Mistral Nemo sometimes makes up file contents instead of using actual tool results.

2. **No conversation memory** - CLI chat mode doesn't persist context between sessions.

3. **Temperature setting** - Changed from 0.0 to 0.3 for Mistral Nemo compatibility, may affect determinism.

## Architecture Decisions Made

| Decision | Choice | Rationale |
|----------|--------|-----------|
| Monorepo structure | `webber-api/`, `webber-cli/` | Separate packages, shared root |
| Sanitized Ollama provider | Custom wrapper | Fixes PydanticAI + Ollama `content: null` bug |
| Dev port 8095 | Separate from prod 8086 | Avoid conflicts with Docker deployment |
| Tool choice "required" | Force tool use | Mistral Nemo needs explicit instruction |
| Temperature 0.3 | Mistral recommendation | 0.0 caused issues with Nemo |
| SearXNG for search | Self-hosted | Privacy, no API keys needed |
| SSE for streaming | Server-Sent Events | Simple, well-supported |

## Quick Reference: What Works Now

```bash
# Start dev server
cd webber-api && ./wakeup.sh

# CLI commands (from webber-cli/)
.venv/bin/webber-cli status                    # Check API connection
.venv/bin/webber-cli explore "find tests"      # One-shot exploration
.venv/bin/webber-cli explore "query" --no-stream  # Batch mode
.venv/bin/webber-cli chat                      # Interactive mode

# API endpoints
curl http://localhost:8095/health
curl http://localhost:8095/agents/
curl -X POST http://localhost:8095/agents/run \
  -H "Content-Type: application/json" \
  -d '{"agent_type":"explore","prompt":"list python files","working_dir":"."}'

# Streaming endpoint
curl -N http://localhost:8095/agents/stream \
  -H "Content-Type: application/json" \
  -d '{"agent_type":"explore","prompt":"find config files","working_dir":"."}'
```
