Model Failover Skill

Automatically switch between LLM providers when one fails. Supports configurable fallback chains, rate limiting, and health monitoring. Inspired by OpenClaw's model failover system.

Setup

Configure your provider chain in environment variables:

# Comma-separated list of providers (in fallback order)
export LLM_PROVIDER_CHAIN="anthropic:claude-3-5-sonnet-20241022,openai:gpt-4o-mini,google:gemini-1.5-flash"

# API keys for each provider
export ANTHROPIC_API_KEY="sk-ant-..."
export OPENAI_API_KEY="sk-..."
export GOOGLE_API_KEY="..."
