# Loom environment configuration
# Copy to .env and fill in your values:  cp env-template .env
# Source before starting the supervisor:  set -a && source .env && set +a

# --- LLM Provider (required) ---
# These three vars configure Prime (reflect, LLM review, chat).
# Lab inherits from these unless overridden below.
# Works with any Anthropic-compatible API (Anthropic, Minimax, etc.)

ANTHROPIC_API_KEY=sk-ant-...
# ANTHROPIC_API_BASE=https://api.anthropic.com
# LOOM_MODEL=claude-sonnet-4-20250514

# Example: Use Minimax for everything
# ANTHROPIC_API_KEY=sk-cp-...
# ANTHROPIC_API_BASE=https://api.minimax.io/anthropic
# LOOM_MODEL=MiniMax-M2.5

# --- Lab LLM provider (optional, overrides Prime config for Labs) ---
# Use when Labs should run a different model/provider than Prime.
# If unset, Labs inherit ANTHROPIC_API_KEY, ANTHROPIC_API_BASE, LOOM_MODEL.
