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-masters 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 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.

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 Masters

Standing on the shoulders of giants. These designers didn't just create beautiful work—they articulated principles that remain relevant decades later.

When to Use This Skill

  • Seeking design inspiration with depth
  • Understanding the reasoning behind classic design
  • Applying proven approaches to modern problems
  • Teaching through historical example
  • Finding appropriate references for a design direction

The Pantheon

Saul Bass (1920-1996)

Domain: Film titles, corporate identity, posters Philosophy: "Design is thinking made visual"

Signature Techniques
  1. Geometric Reduction: Complex ideas → simple shapes
  2. Symbolic Metaphor: Literal → abstract representation
  3. Motion in Stillness: Static images implying movement
  4. Negative Space: What's left out tells the story
  5. Limited Palette: Powerful constraint
Essential Works
  • Man with the Golden Arm (1955): First film title as design
  • Vertigo (1958): Spiral as psychological symbol
  • AT&T Logo (1984): Globe lines suggesting connection
  • Minolta Logo (1981): Stylized 'm' as horizon
Apply His Lesson

Before adding detail, ask: "What's the one essential shape that captures this idea?"

Approach:
1. Identify the core concept
2. Find a visual metaphor
3. Reduce to essential geometry
4. Test if meaning survives reduction
5. Add nothing more

Massimo Vignelli (1931-2014)

Domain: Information design, corporate identity, packaging Philosophy: "If you can design one thing, you can design everything"

The Vignelli Canon
  1. Semantics: What does it mean?
  2. Syntactics: How is it structured?
  3. Pragmatics: How does it function in context?
  4. Discipline: Constraint breeds creativity
  5. Appropriateness: Fit context, not ego
  6. Ambiguity: Welcome a plurality of meanings; reject vagueness
  7. Design is One: Universal principles apply everywhere
  8. Visual Power: Strength through simplicity
  9. Intellectual Elegance: Clever, not complicated
  10. Timelessness: Enduring over fashionable
  11. Responsibility: To the work itself, to the client (economically sound solutions), and to the public
  12. Equity: Respect the recognition an established mark has earned; do not redesign for change's sake

Changes

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.
