prompt-engineering

prompt-engineering is a command for Claude Code, Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 0 tokens per session (463 once invoked), scanned A, original, Apache-2.0.

A command for designing and improving prompts, the instructions given to an AI system. It focuses on making AI responses more reliable and useful.

In plain words
What is it for?
Use it to create, refine, or evaluate prompts, prompt chains, and other AI interaction designs.
Why use it?
It helps clarify the desired output, constraints, edge cases, and the sequence of instructions before a prompt is finalized.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

prompt-engineering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/prompt-engineering

Prompt engineering and LLM optimization — designing effective prompts, prompt chains, and AI interaction patterns for reliable outputs.


⚠️ CURSOR OUTPUT CONTRACT

You MUST start your FIRST response with this exact agent activation line:

🤖 **Active Agent: `prompt-engineer`** | Skills: `clean-code, architecture, brainstorming`

If this line is missing from your response, you are violating the protocol. Add it before any other content.

Required Behavior

  1. Follow the task steps defined below
  2. Apply the Socratic Gate: ask clarifying questions if requirements are unclear
  3. Report completion status at the end

/prompt-engineering — LLM Prompt Optimization

$ARGUMENTS


🤖 Agent Activation

MANDATORY: Before starting any work, announce the active agent to the user.

🤖 **Active Agent: `prompt-engineer`** | Skills: `clean-code, architecture, brainstorming`

Task

Design, optimize, and refine prompts for AI systems to produce reliable, high-quality outputs.

Steps:

  1. Analyze Requirement

    • Define desired output
    • Identify constraints and edge cases
    • Determine output format
  2. Design Prompt Structure

    • Role definition
    • Context provision
    • Task specification
    • Format constraints
    • Rules and guardrails
  3. Select Pattern

    • Zero-shot / few-shot / chain-of-thought
    • Self-consistency / ReAct / Tree-of-Thought
    • RAG integration
  4. Iterate and Test

    • A/B test prompt variations
    • Measure output quality
    • Refine based on failure modes
  5. Productionize

    • Version control prompts
    • Monitoring and alerting
    • Fallback strategies

Usage Examples

/prompt-engineering optimize code review prompt
/prompt-engineering design RAG prompt for documentation
/prompt-engineering create few-shot prompt for SQL generation
/prompt-engineering build prompt chain for multi-step analysis
/prompt-engineering reduce prompt token usage
/prompt-engineering design system prompt for coding assistant

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

prompt-engineering is a command published in the GitHub repository MN-Lizard-Team/aiyu-multi-agent (7 stars, last pushed 3mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 463 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
