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 | $0.00082 | $0.02312 |
| Opus 5 | $0.00041 | $0.01156 |
| Sonnet 5 | $0.00016 | $0.00462 |
| Haiku 4.5 | $0.00008 | $0.00231 |
Grade A, and why
canon-spatial 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 6d 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 — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Spatial Design
Spacing is the third highest-leverage decision after type and color. Inconsistent spacing is the single biggest tell that an interface was generated rather than designed.
Quantified Rules
Grid Base
Pick one base unit and stick to it across the entire system:
| Base | Use case | Source |
|---|---|---|
| 4px | Dense apps, dashboards, data tables | Apple HIG (4pt) |
| 8px | Default for most products | Material 3, Bootstrap |
Rule: every spacing value must be a multiple of the base. No 5px, no 7px, no 13px. Snapping to a grid is the difference between designed and arranged.
Spacing Scale (8px base)
0 = 0px
0.5 = 4px (sub-grid for icon offsets only)
1 = 8px
1.5 = 12px
2 = 16px
3 = 24px
4 = 32px
5 = 40px
6 = 48px
8 = 64px
10 = 80px
12 = 96px
16 = 128px
20 = 160px
24 = 192px
12 to 14 stops is the right total. Fewer feels rigid. More dilutes the system.
Spacing Scale (4px base, dense)
1 = 4px
2 = 8px
3 = 12px
4 = 16px
5 = 20px
6 = 24px
8 = 32px
10 = 40px
12 = 48px
16 = 64px
20 = 80px
24 = 96px
Component Padding
| Component | Padding (8px scale) | Source |
|---|---|---|
| Button (medium) | 12px V, 20px H | Material 3 |
| Button (small) | 8px V, 16px H | |
| Button (large) | 16px V, 24px H | |
| Input field | 12px V, 16px H | |
| Card | 24px all sides | |
| Card (compact) | 16px all sides | |
| Modal | 32px (title), 24px (body), 24px (footer) | |
| Section | 64–96px V on desktop, 48px V on mobile | |
| Page container | 24px H mobile, 48px H tablet, 64px+ H desktop |
Touch Targets
| Platform | Minimum | Source |
|---|---|---|
| iOS | 44 × 44 pt | Apple HIG |
| Android / Material | 48 × 48 dp | Material 3 |
| Web | 44 × 44 px | WCAG 2.5.5 (AAA), 2.5.8 (AA, 24×24 minimum) |
Use 44px as the universal floor. Visual size can be smaller if the tappable area is padded out to 44px via padding or absolute positioning.
Gap Between Elements
Visual hierarchy is created by spacing. Closely-related elements get tighter gaps; distinct sections get wider gaps.
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.

canon-spatial is a skill published in the GitHub repository Dragoon0x/canon (5 stars, last pushed 4mo ago), licensed MIT. It adds 82 tokens to every session and 2,312 once invoked, about $0.0004 per session on Opus 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 2026-09-03.
