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 | $0.00081 | $0.00986 |
| Opus 5 | $0.00041 | $0.00493 |
| Sonnet 5 | $0.00016 | $0.00197 |
| Haiku 4.5 | $0.00008 | $0.00099 |
Grade A, and why
masonry 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 4d 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.
This is a copy
100% identical to masonry — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Masonry Layout
Guides masonry layout design for content with varying heights. Masonry stacks items in columns without distinct rows; items fill gaps like a brick wall. Best for image galleries, portfolios, and discovery-focused platforms.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
When to Use Masonry
| Use masonry when | Use grid when |
|---|---|
| Varying heights | Equal-height items |
| Image-heavy; varied aspect ratios | Products, templates (consistent) |
| Gallery, portfolio, showcase | Card grid |
| Discovery, browsing; visual-first | Structured browsing |
See grid for equal-height grid; card for card structure.
Masonry vs Grid vs Bento vs Carousel
| Layout | Structure | Best for |
|---|---|---|
| Grid | Equal rows and columns; uniform items | Products, templates, features |
| Masonry | Columns; items stack without rows; gaps filled | Pinterest, Behance; varied content |
| Bento | Intentional sections; predefined sizes | Homepage, dashboard; Apple-style |
| Carousel | Slides; one/few visible; swipe/click | Testimonials, logos, featured items; see carousel |
Masonry Structure
| Element | Purpose |
|---|---|
| Columns | 2–4 columns; fluid or fixed |
| Items | Varying heights; natural aspect ratio |
| Gap | Consistent horizontal and vertical spacing |
| Order | Top-to-bottom fill within columns |
Implementation
- CSS columns:
column-count; simple, no JS; but items flow top-to-bottom then next column - Masonry.js / libraries: True masonry (left-to-right fill); may need JS
- CSS Grid +
grid-auto-flow: dense: Approximate; no JS; see grid for dense grid
Note: Pure masonry can create accessibility challenges (screen reader order); ensure logical DOM order.
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.
