# Provider Selection (anthropic, openai, or openrouter)
PROVIDER=anthropic

# API Keys - Set the key for your chosen provider
ANTHROPIC_API_KEY=your_anthropic_api_key_here
OPENAI_API_KEY=your_openai_api_key_here
OPENROUTER_API_KEY=your_openrouter_api_key_here

# OPENROUTER_API_KEY doubles as a UNIVERSAL FALLBACK:
# If PROVIDER=anthropic but ANTHROPIC_API_KEY is missing, or PROVIDER=openai but
# OPENAI_API_KEY is missing, the agent automatically routes through OpenRouter
# using the OpenAI-compatible API (as long as OPENROUTER_API_KEY is set).
# On fallback the model id is mapped/prefixed automatically:
#   claude-sonnet-* -> anthropic/claude-sonnet-4.6
#   claude-haiku-*  -> anthropic/claude-haiku-4.5
#   claude-opus-* / other claude-* -> anthropic/claude-opus-4.8
#   gpt-* / o1-*    -> openai/<model>   (e.g. gpt-4o-mini -> openai/gpt-4o-mini)
# So you can run with ONLY an OPENROUTER_API_KEY set.
