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

design-fundamentals 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 2mo 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.

Design Thinking Fundamentals

For Claude: This skill provides foundational design thinking knowledge to help users understand the Design Partner workflow and methodology.

Core Design Thinking Process

Design Partner follows a structured 5-phase approach:

1. Context Capture

  • Goal: Gather essential problem context
  • Questions: Who is this for? What job needs to be done? What constraints matter?
  • Output: Design Brief with problem, users, constraints, and success criteria

2. Divergent Exploration

  • Goal: Generate multiple solution directions
  • Approach: Explore different assumptions, perspectives, and approaches
  • Output: 5+ idea cards with diverse core assumptions

3. Convergent Selection

  • Goal: Choose the most promising direction(s)
  • Approach: Evaluate ideas based on feasibility, desirability, and viability
  • Output: Selected idea(s) for deeper exploration

4. Visualization & Prototyping

  • Goal: Create concrete artifacts to explore the idea
  • Approach: Generate UI mockups, concept art, user scenarios
  • Output: High-resolution images via DALL-E 3 or Gemini Imagen

5. Critique & Iteration

  • Goal: Identify risks and refine the approach
  • Approach: Systematic risk analysis and rapid iteration
  • Output: Refined concept with addressed concerns

Ideation Techniques

Divergent Thinking (Broadening)

  • Reframe the problem from different perspectives
  • Challenge core assumptions
  • Explore extreme constraints or inversions
  • Consider different user types or contexts

Convergent Thinking (Narrowing)

  • Evaluate based on impact and feasibility
  • Force-rank options
  • Identify must-have vs nice-to-have features
  • Select direction based on success criteria

Visual Exploration

Natural Language

Simply say "show me what this looks like" and Design Partner will:

  1. Extract context from your conversation
  2. Build an enhanced prompt from your Design Brief
  3. Generate a high-resolution image
  4. Link it to your design session

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.
