promptlint

Lint and improve LLM prompts using the promptlint CLI. Use when writing, reviewing, or optimizing prompts for GPT-4, Claude, Gemini, or any LLM — whether in plain text files or embedded in Python/TypeScript code. Activates when the user writes prompts, asks to optimize or review a prompt, mentions prompt injection, or works with LangChain/OpenAI/Anthropic SDK code containing prompt strings.
