Skill instructions
Building LLM-Powered Applications with Claude This skill helps you build LLM-powered applications with Claude. Choose the right surface based on your needs, detect the project language, then read the relevant language-specific documentation. Before You Start Scan the target file (or, if no target file, the prompt and project) for non-Anthropic provider markers - import openai, from openai, langchainopenai, OpenAI(, gpt-4, gpt-5, file names like agent-openai.py or -generic.py, or any explicit instruction to keep the code provider-neutral. If you find any, stop and tell the user that this skill produces Claude/Anthropic SDK code; ask whether they want to switch the file to Claude or want a non-Claude implementation. Do not edit a non-Anthropic file with Anthropic SDK calls.
