Jason Woltje f0fd0bed41 feat(#144): Implement agent profiles
- Add Capability enum (HIGH, MEDIUM, LOW) for agent difficulty levels
- Add AgentName enum for all 5 agents (opus, sonnet, haiku, glm, minimax)
- Implement AgentProfile data structure with validation
  - context_limit: max tokens for context window
  - cost_per_mtok: cost per million tokens (0 for self-hosted)
  - capabilities: list of difficulty levels the agent handles
  - best_for: description of optimal use cases
- Define profiles for all 5 agents with specifications:
  - Anthropic models (opus, sonnet, haiku): 200K context, various costs
  - Self-hosted models (glm, minimax): 128K context, free
- Implement get_agent_profile() function for profile lookup
- Add comprehensive test suite (37 tests, 100% coverage)
  - Profile data structure validation
  - All 5 predefined profiles exist and are correct
  - Capability enum and AgentName enum tests
  - Best_for validation and capability matching
  - Consistency checks across profiles

Mosaic Coordinator

FastAPI webhook receiver for Gitea issue events, enabling autonomous task coordination for AI agents.

Overview

The coordinator receives webhook events from Gitea when issues are assigned, unassigned, or closed. It verifies webhook authenticity via HMAC SHA256 signature and routes events to appropriate handlers.

Features

  • HMAC SHA256 signature verification
  • Event routing (assigned, unassigned, closed)
  • AI-powered issue metadata parsing (using Anthropic Sonnet)
  • Context estimation and agent assignment
  • Dependency tracking (blocks/blocked_by)
  • Comprehensive logging
  • Health check endpoint
  • Docker containerized
  • 95%+ test coverage

Development

Prerequisites

  • Python 3.11+
  • pip or uv package manager

Setup

# Install dependencies
pip install -e ".[dev]"

cp .env.example .env

# Edit .env with your values
# GITEA_WEBHOOK_SECRET, GITEA_URL, ANTHROPIC_API_KEY

# Run server
uvicorn src.main:app --reload --port 8000

API Endpoints

POST /webhook/gitea

Receives Gitea webhook events.

Headers:

  • X-Gitea-Signature: HMAC SHA256 signature of request body

Response:

  • 200 OK: Event processed successfully
  • 401 Unauthorized: Invalid or missing signature
  • 422 Unprocessable Entity: Invalid payload

GET /health

Health check endpoint.

Response:

  • 200 OK: Service is healthy
