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.

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 | $0.00095 | $0.02076 |
| Opus 5.5 | $0.00038 | $0.00830 |
| Sonnet 5.5 | $0.00019 | $0.00415 |
| Haiku 4.5 | $0.00010 | $0.00208 |
Grade A, and why
design-evaluation-scoring 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 5d 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.

Visual Quality Is Not Subjective -- It Is Measurable Across 8 Dimensions
Empirical aesthetics research (VisAWI by Moshagen & Thielsch, Lavie & Tractinsky 2004, Seckler et al. 2015) shows that perceived visual quality is not arbitrary opinion -- it decomposes into measurable dimensions. The 8-dimension framework below maps each dimension to research-validated constructs, giving you a repeatable, objective scoring system for any visual artifact.
The 8 Dimensions
| # | Dimension | Research Alignment | What It Measures |
|---|---|---|---|
| 1 | Layout | Seckler et al. (structural clarity) | Grid adherence, alignment, spatial composition, responsive behavior |
| 2 | Typography | Bringhurst, Butterick | Type scale, font pairing, line length, readability, hierarchy |
| 3 | Color | Reinecke et al., 60-30-10 rule | Palette harmony, contrast compliance, shade scale, dark mode |
| 4 | Whitespace | Pracejus et al. (perceptions of luxury) | Spacing consistency, density ratio, separation techniques |
| 5 | Hierarchy | Refactoring UI (emphasis/de-emphasis) | Focal points, 3-tier clarity, scanning patterns, CTA prominence |
| 6 | Consistency | VisAWI Craftsmanship subscale | Design tokens, component uniformity, cross-screen coherence |
| 7 | Craftsmanship | VisAWI Craftsmanship subscale | Pixel precision, image quality, shadows, micro-interactions, CLS |
| 8 | Expression | Lavie & Tractinsky (Expressive aesthetics) | Brand personality, visual motifs, illustration, motion, originality |
Quick Scoring Rubric
Score each dimension 1-5. Total is out of 40.
| Score | Meaning | Indicators |
|---|---|---|
| 1 | Broken | Fundamental violations; unusable or visually chaotic |
| 2 | Weak | Multiple issues; feels amateur or unfinished |
| 3 | Adequate | Meets basics; no major violations but lacks refinement |
| 4 | Good | Consistent and polished; minor improvements possible |
| 5 | Excellent | Research-aligned best practice; cohesive and intentional |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

design-evaluation-scoring is a skill published in the GitHub repository oborchers/fractional-cto (32 stars, last pushed 5d ago), licensed MIT. It adds 95 tokens to every session and 2,076 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-13.
