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 | $0.00089 | $0.01879 |
| Opus 5.5 | $0.00036 | $0.00752 |
| Sonnet 5.5 | $0.00018 | $0.00376 |
| Haiku 4.5 | $0.00009 | $0.00188 |
Grade A, and why
craftsmanship-polish 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.
How it starts
The opening of the file, as written. The whole thing — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Craftsmanship Is the Multiplier — A Simple Design Flawlessly Executed Beats a Brilliant Design Sloppily Built
Craftsmanship is the strongest single correlate with perceived visual quality in the VisAWI model (Moshagen & Thielsch, 2010). Users cannot articulate why a polished interface feels trustworthy, but they punish sloppiness instantly. Every blurry image, inconsistent radius, and missing hover state erodes credibility.
Pixel-Perfect Alignment
Enforce the >90% grid alignment rule from the layout-spatial-structure skill. Misalignment of even 1px between adjacent elements is visible at retina resolution.
Debug technique: Add outline: 1px solid rgba(255,0,0,0.3) to all elements temporarily. Misaligned edges become obvious.
Image Quality
| Rule | Requirement |
|---|---|
| Resolution | All images must be >=2x rendered resolution (e.g., 800px image for a 400px container) |
| Format priority | AVIF > WebP > JPEG (use <picture> with fallbacks) |
| Hero image budget | <=300KB after compression |
| Lazy loading | All images below the fold use loading="lazy" |
| Aspect ratio | Always specify width and height attributes to prevent CLS |
Shadow Elevation System
Use layered box-shadows for realistic depth. Single-layer shadows look flat and artificial. Define exactly 5 levels and use them consistently.
| Level | Name | Use Case | Box-Shadow |
|---|---|---|---|
| 0 | Flat | Inline elements, flush cards | none |
| 1 | Card | Cards, tiles, raised surfaces | 0 1px 2px rgba(0,0,0,0.06), 0 1px 3px rgba(0,0,0,0.1) |
| 2 | Dropdown | Dropdowns, popovers, tooltips | 0 4px 6px rgba(0,0,0,0.07), 0 2px 4px rgba(0,0,0,0.06) |
| 3 | Modal | Modals, dialogs, drawers | 0 10px 15px rgba(0,0,0,0.1), 0 4px 6px rgba(0,0,0,0.05) |
| 4 | Popover | Floating toolbars, command palettes | 0 20px 25px rgba(0,0,0,0.1), 0 8px 10px rgba(0,0,0,0.04) |
Rule: Higher elevation = larger offset + larger blur + lower opacity. Never use a single heavy shadow.
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.

craftsmanship-polish is a skill published in the GitHub repository oborchers/fractional-cto (32 stars, last pushed 5d ago), licensed MIT. It adds 89 tokens to every session and 1,879 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.
