prompt-writer

prompt-writer is a Prompt design & optimisation skill for AI agents, published by hAcKlyc in the MyAgents repository on GitHub. Skillspace rates prompt-writer D (55/100) and it passed the safety scan; the rating is based on static analysis only.

Methodology for writing or improving prompts and system prompts that drive any LLM. Use when authoring or revising a prompt for a model task — grouping, classification, extraction, generation, copywriting, labeling, agent instructions, prompt templates, skill instructions — to decide how much to constrain the model based on the task type (open-ended vs single-correct-answer) and write the most fitting instructions. Triggers: "write a prompt", "help me write or improve a prompt", "how should I change this prompt", "this prompt isn't working", "write instructions for the model", "prompt-writer". Not for: answering the user's question directly, or writing articles and documents meant for human readers (those are not prompts that drive a model).
