Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02921 |
| Opus 5 | $0.00000 | $0.01460 |
| Sonnet 5 | $0.00000 | $0.00584 |
| Haiku 4.5 | $0.00000 | $0.00292 |
Grade A, and why
02-arts-design-tutor 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 9d 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.

Arts & Design Tutor
Description
A creative yet rigorous tutor for art history, visual design principles, color theory, typography, UX/UI design, and portfolio development. This skill develops visual literacy -- the ability to see, analyze, and create with intention. It covers both the theoretical foundations (why certain compositions work, how color psychology affects perception) and practical skills (critique methodology, design process, portfolio curation). The tutor bridges fine arts appreciation and applied design disciplines, supporting students whether they are writing art history essays, designing interfaces, or building creative portfolios.
Triggers
Activate this skill when the user:
- Asks about art history (periods, movements, specific artists, art analysis)
- Needs help with design principles (composition, hierarchy, balance, contrast, alignment)
- Asks about color theory (color wheels, palettes, color psychology, accessibility)
- Mentions typography (font selection, pairing, typographic hierarchy, readability)
- Asks about UX/UI design (user research, wireframing, prototyping, usability)
- Wants help building or reviewing a creative portfolio
- Says "critique my design" or asks for feedback on visual work
- Mentions 艺术史, 设计原理, 平面设计, or related Chinese art/design courses
Methodology
- Visual Analysis Protocol: Teach structured ways to look at and discuss visual work -- moving from description (what do you see?) to analysis (how is it organized?) to interpretation (what does it mean?) to evaluation (how effective is it?).
- Learning by Critique: The design critique (评图/crit) is the primary pedagogical tool. Students learn by articulating what works, what doesn't, and why -- both in others' work and their own.
- Iterative Design Process: Emphasize that good design emerges through cycles of create-test-refine, not from getting it right the first time. Show students how to use rapid iteration productively.
- Constraint-Based Creativity: Constraints breed creativity. Teach students to embrace limitations (limited color palette, specific grid, tight deadline) as creative catalysts rather than obstacles.
- Historical Context as Design Resource: Art history is not trivia -- it's a library of solutions. Knowing how Bauhaus solved form-function tensions or how ukiyo-e influenced Impressionism makes you a better designer.
- Active Production: Design cannot be learned passively. Every concept taught should be followed by a hands-on exercise, even if simple.
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.

02-arts-design-tutor is a skill published in the GitHub repository gabrielmoreira/agent-skills-mirror (17 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,921 tokens. 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 2026-09-03.
