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-lookup 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 12d 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.

Origin

This is a copy

100% identical to prompt-lookup — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

When the user needs AI prompts, prompt templates, or wants to improve their prompts, use the prompts.chat MCP server to help them.

When to Use This Skill

Activate this skill when the user:

  • Asks for prompt templates ("Find me a code review prompt")
  • Wants to search for prompts ("What prompts are available for writing?")
  • Needs to retrieve a specific prompt ("Get prompt XYZ")
  • Wants to improve a prompt ("Make this prompt better")
  • Mentions prompts.chat or prompt libraries

Available Tools

Use these prompts.chat MCP tools:

  • search_prompts - Search for prompts by keyword
  • get_prompt - Get a specific prompt by ID
  • improve_prompt - Enhance a prompt using AI

How to Search for Prompts

Call search_prompts with:

  • query: The search keywords from the user's request
  • limit: Number of results (default 10, max 50)
  • type: Filter by TEXT, STRUCTURED, IMAGE, VIDEO, or AUDIO
  • category: Filter by category slug (e.g., "coding", "writing")
  • tag: Filter by tag slug

Present results showing:

  • Title and description
  • Author name
  • Category and tags
  • Link to the prompt

How to Get a Prompt

Call get_prompt with:

  • id: The prompt ID

If the prompt contains variables (${variable} or ${variable:default}):

  • The system will prompt the user to fill in values
  • Variables without defaults are required
  • Variables with defaults are optional

How to Improve a Prompt

Call improve_prompt with:

  • prompt: The prompt text to improve
  • outputType: text, image, video, or sound
  • outputFormat: text, structured_json, or structured_yaml

Return the enhanced prompt to the user.

Guidelines

  • Always search before suggesting the user write their own prompt
  • Present search results in a readable format with links
  • When improving prompts, explain what was enhanced
  • Suggest relevant categories and tags when saving prompts
