ai-llm-development
MANDATORY invocation for ALL LLM-related work. Invoke immediately when:
- ANY mention of model names, IDs, or versions
- ANY configuration of AI providers or APIs
- ANY defaults/constants for LLM settings
- ANY prompt engineering or modification
- ANY discussion of model capabilities or features
- ANY changes to AI-related dependencies
- Reading/writing .env files with AI config
- Modifying aiProviders.ts, prompts.ts, or similar
