Describe the bug
A clear and concise description of what the bug is.

Running sparc --model gpt-4o-mini-2024-07-18 --provider openrouter. If I run with message sparc only performs the research and stops. If I run with --chat I get the following message when asking to add a feature:

╭────────────────────────────────────── ❌ Tool Error ──────────────────────────────────────╮
│ Error: 1 validation error for ChatAnthropic api_key Input should be a valid string        │

.env:

# Optional: Expert knowledge configuration
EXPERT_PROVIDER=openai                   # Default provider for expert queries (anthropic|openai|openrouter)
EXPERT_MODEL=o1-preview                      # Model to use for expert knowledge queries

# Optional: Default provider settings
DEFAULT_PROVIDER=openrouter               # Default LLM provider (anthropic|openai|openrouter)
DEFAULT_MODEL=gpt-4o-mini-2024-07-18

# Optional: Development settings
DEBUG=false                              # Enable debug logging
COWBOY_MODE=false                        # Skip command approval prompts

Expected behavior
I'm expecting that I can use openai models to execute the development tasks.

Same here. If ANTHROPIC_API_KEY is not set, there's a "Missing required dependencies:" error and the process stops.
If ANTHROPIC_API_KEY is set, Claude is used whatever the settings for DEFAULT_PROVIDER say.
The usual 40,000 tokens per minute for Claude are not enough, and the wait time is doubled whenever I run into the limit.
