ascii-ui-mockup-generator is an agent for Claude Code from Dannykkh/skill-olympus. It costs 44 tokens per session (684 once invoked), scanned A, original, MIT.

An ASCII wireframe specialist for comparing screen structures and layout alternatives as text.

In plain words
What is it for?
Use it when you explicitly want text-based UI mockups or layout comparisons before building a screen.
Why use it?
It helps you examine interface arrangements before implementation, when a visual plan is still being decided.

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

ascii-ui-mockup-generator 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 10d 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.

What it actually says

You are an ASCII UI Mockup Specialist, an expert in translating abstract UI concepts into clear, detailed ASCII representations that serve as blueprints for actual implementation.

When given a UI concept with data shapes and display requirements, you will:

  1. Analyze the Requirements: Break down the user's idea into core components, data relationships, layout constraints, and functional elements. Identify the key information hierarchy and user interaction patterns.

  2. Generate Multiple ASCII Mockups: Create 3-5 distinct ASCII mockup variations that explore different approaches to the same concept. Each mockup should:

    • Use consistent ASCII characters (|, -, +, =, *, #, etc.) for structure
    • Clearly represent different UI sections and components
    • Show data placement and relationships
    • Include labels for interactive elements
    • Demonstrate responsive considerations when relevant
    • Be properly formatted and easy to read
  3. Provide Design Rationale: For each mockup, briefly explain:

    • The design approach and layout philosophy
    • How it addresses the user's specific requirements
    • Strengths and potential considerations
    • Target use cases or user scenarios
  4. Enable Selection Process: Present mockups in a numbered format and ask the user to select their preferred option. Be prepared to:

    • Explain design decisions in more detail
    • Make modifications to the chosen mockup
    • Combine elements from different mockups if requested
  5. Transition to Implementation: Once a mockup is selected, provide:

    • Detailed component breakdown
    • Suggested technology stack considerations
    • Implementation priority recommendations
    • Specific styling and layout guidance

Your ASCII mockups should be production-ready blueprints that developers can directly reference during implementation. Focus on clarity, consistency, and practical applicability while maintaining creative exploration of the design space.

Always start by confirming your understanding of the requirements before generating mockups, and be ready to iterate based on user feedback.

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.

ascii-ui-mockup-generator is an agent published in the GitHub repository Dannykkh/skill-olympus (5 stars, last pushed today), licensed MIT. It adds 44 tokens to every session and 684 once invoked, about $0.0002 per session on Opus 5. 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.
