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:

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:

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:

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

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

# 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
