Agent Tools & Google Calendar Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Implement the Pydantic AI Tools (Read/Write) and the Google Calendar Adapter to allow the SDR to check availability and book appointments deterministically.

Architecture: We use Dependency Injection via Pydantic AI's RunContext and AgentDeps. External integrations (Google Calendar) are isolated via the ICalendarAdapter interface. Tools are defined as simple Python functions decorated or registered with the agent, relying on Pydantic for validation.

Tech Stack: Python 3.12, Pydantic AI, Beanie (MongoDB), Google API Python Client.

Task 1: Add Google Calendar Dependencies

Files: - Modify: pyproject.toml

Step 1: Install dependencies using uv

Run: uv add google-api-python-client google-auth

Step 2: Commit

git add pyproject.toml uv.lock
git commit -m "build: add google-api-python-client and google-auth dependencies"

Task 2: Define Agent Dependencies (Context)

Files: - Create: src/amon_claw/infrastructure/llm/agents/deps.py - Create: tests/infrastructure/llm/agents/test_deps.py

Step 1: Write the failing test

from uuid import uuid4
from amon_claw.infrastructure.llm.agents.deps import AgentDeps

def test_agent_deps_instantiation():
    deps = AgentDeps(
        tenant_id=uuid4(),
        customer_id=uuid4(),
        tenant_repository="mock_repo",
        service_repository="mock_repo",
        professional_repository="mock_repo",
        appointment_repository="mock_repo",
        calendar_adapter="mock_adapter"
    )
    assert deps.tenant_id is not None

Step 2: Run test to verify it fails

Run: uv run pytest tests/infrastructure/llm/agents/test_deps.py Expected: FAIL

Step 3: Implement AgentDeps

from pydantic import BaseModel, ConfigDict
from uuid import UUID
from typing import Any

class AgentDeps(BaseModel):
    model_config = ConfigDict(arbitrary_types_allowed=True)

    tenant_id: UUID
    customer_id: UUID
    tenant_repository: Any
    service_repository: Any
    professional_repository: Any
    appointment_repository: Any
    calendar_adapter: Any

Step 4: Run test to verify it passes

Run: uv run pytest tests/infrastructure/llm/agents/test_deps.py Expected: PASS

Step 5: Commit

git add src/amon_claw/infrastructure/llm/agents/deps.py tests/infrastructure/llm/agents/test_deps.py
git commit -m "feat(llm): create AgentDeps model for Pydantic AI context"

Task 3: Define Calendar Interface

Files: - Create: src/amon_claw/application/interfaces/calendar.py

Step 1: Implement ICalendarAdapter

from abc import ABC, abstractmethod
from datetime import datetime
from typing import List

class ICalendarAdapter(ABC):
    @abstractmethod
    async def get_free_slots(self, calendar_id: str, start_date: datetime, end_date: datetime, duration_minutes: int) -> List[datetime]:
        """Fetch available time slots for a given duration."""
        pass

    @abstractmethod
    async def create_event(self, calendar_id: str, summary: str, description: str, start_time: datetime, end_time: datetime) -> str:
        """Create an event and return the external event ID."""
        pass

Step 2: Commit

git add src/amon_claw/application/interfaces/calendar.py
git commit -m "feat(application): define ICalendarAdapter interface"
