# Timmy Time — Implementation Summary

**Date:** 2026-02-25  
**Phase:** 1, 2 Complete (MCP, Event Bus, Agents)  
**Status:** ✅ Ready for Phase 3 (Cascade Router)

---

## What Was Built

### 1. MCP (Model Context Protocol) ✅

**Location:** `src/mcp/`

| Component | Purpose | Status |
|-----------|---------|--------|
| Registry | Tool catalog with health tracking | ✅ Complete |
| Server | MCP protocol implementation | ✅ Complete |
| Schemas | JSON schema utilities | ✅ Complete |
| Bootstrap | Auto-load all tools | ✅ Complete |

**Features:**
- 6 tools registered with full schemas
- Health tracking (healthy/degraded/unhealthy)
- Metrics collection (latency, error rates)
- Pattern-based discovery
- `@register_tool` decorator

**Tools Implemented:**
```python
web_search    # DuckDuckGo search
read_file     # File reading
write_file    # File writing (with confirmation)
list_directory # Directory listing
python        # Python execution
memory_search # Vector memory search
```

### 2. Event Bus ✅

**Location:** `src/events/bus.py`

**Features:**
- Async publish/subscribe
- Wildcard pattern matching (`agent.task.*`)
- Event history (last 1000 events)
- Concurrent handler execution
- System-wide singleton

**Usage:**
```python
from events.bus import event_bus, Event

@event_bus.subscribe("agent.task.*")
async def handle_task(event):
    print(f"Task: {event.data}")

await event_bus.publish(Event(
    type="agent.task.assigned",
    source="timmy",
    data={"task_id": "123"}
))
```

### 3. Sub-Agents ✅

**Location:** `src/agents/`

| Agent | ID | Role | Key Tools |
|-------|-----|------|-----------|
| Seer | seer | Research | web_search, read_file, memory_search |
| Forge | forge | Code | python, write_file, read_file |
| Quill | quill | Writing | write_file, read_file, memory_search |
| Echo | echo | Memory | memory_search, read_file, write_file |
| Helm | helm | Routing | memory_search |
| Timmy | timmy | Orchestrator | All tools |

**BaseAgent Features:**
- Agno Agent integration
- MCP tool registry access
- Event bus connectivity
- Structured logging
- Task execution framework

**Orchestrator Logic:**
```python
timmy = create_timmy_swarm()

# Automatic routing:
# - Simple questions → Direct response
# - "Remember..." → Echo agent
# - Complex tasks → Helm routes to specialist
```

### 4. Memory System (Previously Complete) ✅

**Three-Tier Architecture:**

```
Tier 1: Hot Memory (MEMORY.md)
   ↓ Always loaded
   
Tier 2: Vault (memory/)
   ├── self/identity.md
   ├── self/user_profile.md
   ├── self/methodology.md
   ├── notes/*.md
   └── aar/*.md
   
Tier 3: Semantic Search
   └── Vector embeddings over vault
```

**Handoff Protocol:**
- `last-session-handoff.md` written at session end
- Auto-loaded at next session start

## Usage Example

```python
from agents import create_timmy_swarm

# Create fully configured Timmy
timmy = create_timmy_swarm()

# Simple chat (handles directly)
response = await timmy.orchestrate("What is your name?")

# Research (routes to Seer)
response = await timmy.orchestrate("Search for Bitcoin news")

# Code (routes to Forge)
response = await timmy.orchestrate("Write a Python script to...")

# Memory (routes to Echo)
response = await timmy.orchestrate("What did we discuss yesterday?")
```

## Next: Phase 3 (Cascade Router)

To complete the brief, implement:

### 1. Cascade LLM Router
```yaml
# config/providers.yaml
providers:
  - name: ollama-local
    type: ollama
    url: http://localhost:11434
    priority: 1
    models: [llama3.2, deepseek-r1]
  
  - name: openai-backup
    type: openai
    api_key: ${OPENAI_API_KEY}
    priority: 2
    models: [gpt-4o-mini]
```

Features:
- Priority-ordered fallback
- Latency/error tracking
- Cost accounting
- Health checks

### 2. Self-Upgrade Loop
- Detect failures from logs
- Propose fixes via Forge
- Present to user for approval
- Apply changes with rollback

### 3. Dashboard Integration
- Tool registry browser
- Agent activity feed
- Memory browser
- Upgrade queue
