jevify
Find where TypeSafe AI's Jev (a System One model that returns typed Choice, Noul and Score judgments with probabilities instead of generated text) can make an app faster or cheaper, then design the actual questions, composition code and a fair evaluation. Use whenever the user mentions Jev, TypeSafe, System One, or "Jevify this", and also when they want to replace or cut the cost or latency of an LLM classifier, router, reranker, judge, rubric check, guardrail, memory selector, or extraction verifier, want to review or rewrite existing Jev questions, or ask whether a codebase has LLM calls worth moving to a cheaper decision model, even if they never name Jev.

claude-api
Reference for the Claude API / Anthropic SDK โ model ids, pricing, params, streaming, tool use, MCP, agents, caching, token counting, model migration. TRIGGER โ read BEFORE opening the target file; don't skip because it "looks like a one-liner" โ whenever: the prompt names Claude/Anthropic in any form (Claude, Anthropic, Fable, Opus, Sonnet, Haiku, `anthropic`, `@anthropic-ai`, `claude-*`, `us.anthropic.*`, `[1m]`); the user asks about an LLM (pricing/model choice/limits/caching) โ never answer from memory; OR the task is LLM-shaped with provider unstated (agent/MCP/tool-definition/multi-agent/RAG/LLM-judge/computer-use; generate/summarize/extract/classify/rewrite/converse over NL; debugging refusals/cutoffs/streaming/tool-calls/tokens). SKIP only when another provider is being worked on (overrides all triggers): OpenAI/GPT/Gemini/Llama/Mistral/Cohere/Ollama named in the query; OR `grep -rE 'openai|langchain_openai|google.generativeai|genai|mistralai|cohere|ollama'` over the project hits (run this grep FIRST if no provider named โ don't Read the file).
