Use this skill when the user needs to write the actual instructional text that defines how an AI agent behaves. This is the skill for crafting the core "brain instructions" — the system prompt, persona, or behavioral rules that go into making an AI assistant, chatbot, or agent act in a specific way. Trigger for requests to: - Create or design a system prompt, instruction set, or persona for any AI agent - Write the "instructions" field for a custom GPT, Claude project, or similar platform -…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent System Prompt Generator A structured workflow for crafting effective LLM agent system prompts, from scratch or from an existing draft. ## When to Use This Skill - Creating a new agent from scratch — user describes what they want, you interview and draft - Improving an existing prompt — user provides the current version, you diagnose and rewrite - Refactoring a prompt for a different platform (e.g., moving from OpenAI to Claude) ## Core Philosophy A system prompt is a contract between the developer and the model. It should be: - **Clear** — the model never has to guess what's expected - **Complete** — covers the agent's role, boundaries, behavior, and output format - **Concise** — every sentence earns its place; fluff dilutes signal The goal is not to write a long prompt, but to write a *precise* one. --- ## Step 1: Gather Requirements Interview the user to understand the agent's purpose. Ask these questions (adapt to context — if the user already provided some of this, don't re-ask): ### 1.1 Identity & Role - What is this agent's name/identity? - What role does it play? (e.g., "senior code reviewer", "customer support agent", "data analyst") …

How to install
mdr add ahoo-wang/skills/agent-system-prompt@sha256:11754c7ac5810385The line at the top of this page pins the label git:20260527.808710c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
