# ADR-001: Clay Client Initialization

## Status
Accepted

## Context
We need to decide how to initialize the Clay client across our application.

## Decision
We will use the singleton pattern with lazy initialization.

## Consequences
- Pro: Single client instance, connection reuse
- Pro: Easy to mock in tests
- Con: Global state requires careful lifecycle management

## Enforcement
- ESLint rule: clay/use-singleton-client
- CI check: grep for "new ClayClient(" outside allowed files
