## Overview

| Aspect | Details |
|--------|---------|
| **Input** | Context Store from ln-770 |
| **Output** | Health check endpoints and Kubernetes probe configuration |
| **Stacks** | .NET (AspNetCore.Diagnostics.HealthChecks), Python (FastAPI routes) |

## Phase 1: Receive Context + Identify Dependencies

Accept Context Store and scan for dependencies to monitor.

**Required Context:**
- `STACK`: .NET or Python
- `PROJECT_ROOT`: Project directory path

**Idempotency Check:**
- .NET: Grep for `AddHealthChecks` or `MapHealthChecks`
- Python: Grep for `/health` route
- If found: Return `{ "status": "skipped" }`

**Dependency Detection:**

| Dependency | .NET Detection | Python Detection |
|------------|----------------|------------------|
| PostgreSQL | `Npgsql` in csproj | `psycopg2` or `asyncpg` in requirements |
| MySQL | `MySql.Data` in csproj | `mysql-connector-python` in requirements |
| Redis | `StackExchange.Redis` in csproj | `redis` in requirements |
| RabbitMQ | `RabbitMQ.Client` in csproj | `pika` or `aio-pika` in requirements |
| MongoDB | `MongoDB.Driver` in csproj | `pymongo` in requirements |

## Phase 2: Design Health Check Strategy

Define three types of health endpoints per Kubernetes best practices.
