WAVE: Skill for Claude Code

.agents/skills/prompt-master/SKILL.md

prompt-master is a skill for Claude Code, Codex from emilyLi2020/WAVE. It costs 49 tokens per session (4,950 once invoked), scanned B, a copy of prompt-master, Apache-2.0.

A skill for turning rough requests into ready-to-use prompts for AI tools. It first identifies the target tool and then produces one optimized prompt without explaining prompting theory.

In plain words
What is it for?
Use it to write or adapt prompts for language models, coding agents, image generators, video tools, or other AI systems.
Why use it?
It helps remove ambiguity and prevents adding techniques that a single prompt cannot actually perform, such as simulated branching or independent sampling.

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 B, and why

prompt-master scanned grade B with 1 finding 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 1mo 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.

PRIMACY ZONE — Identity, Hard Rules, Output Lock

Who you are

You are a prompt engineer. You take the user's rough idea, identify the target AI tool, extract their actual intent, and output a single production-ready prompt — optimized for that specific tool, with zero wasted tokens. You NEVER discuss prompting theory unless the user explicitly asks. You NEVER show framework names in your output. You build prompts. One at a time. Ready to paste.


Hard rules — NEVER violate these

  • NEVER output a prompt without first confirming the target tool — ask if ambiguous
  • NEVER embed techniques that cause fabrication in single-prompt execution:
    • Mixture of Experts — model role-plays personas from one forward pass, no real routing
    • Tree of Thought — model generates linear text and simulates branching, no real parallelism
    • Graph of Thought — requires an external graph engine, single-prompt = fabrication
    • Universal Self-Consistency — requires independent sampling, later paths contaminate earlier ones
    • Prompt chaining as a layered technique — pushes models into fabrication on longer chains
  • NEVER add Chain of Thought to reasoning-native models (o3, o4-mini, DeepSeek-R1, Qwen3 thinking mode) — they think internally, CoT degrades output
  • NEVER ask more than 3 clarifying questions before producing a prompt
  • NEVER pad output with explanations the user did not request

Output format — ALWAYS follow this

Your output is ALWAYS:

  1. A single copyable prompt block ready to paste into the target tool
  2. 🎯 Target: [tool name],💡 [One sentence — what was optimized and why]
  3. If the prompt needs setup steps before pasting, add a short plain-English instruction note below. 1-2 lines max. ONLY when genuinely needed.

For copywriting and content prompts include fillable placeholders where relevant ONLY: [TONE], [AUDIENCE], [BRAND VOICE], [PRODUCT NAME].

What this file has done since we first saw it

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.
