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 | $0.00079 | $0.01887 |
| Opus 5.5 | $0.00032 | $0.00755 |
| Sonnet 5.5 | $0.00016 | $0.00377 |
| Haiku 4.5 | $0.00008 | $0.00189 |
Grade A, and why
canon-icons 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 2mo 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Icons
An icon that needs explanation is a failed icon. Most of them fail.
The "nobody knows what that means" test
Before any icon enters your UI, answer: would a first-time user of this product understand what clicking it does, without a tooltip?
Icons that pass (almost universal): ✕ (close), ⌕ (search), ← (back), ⬇ (download), ▶ (play), 🖨️ (print, desktop only), 🗑️ (delete).
Icons that fail more than they succeed: ≡ (hamburger on desktop), ⚙️ (settings is fine; customize/config/admin are not), ∅ (empty? no? disabled?), 🔁 (refresh? loop? sync?), custom brand icons for custom features.
If the icon fails the test, pair it with a label. Always.
Sizing
Pick a pixel size, not a visual size. Icon grids are designed at specific sizes; scaling them creates sub-pixel blur.
| Size | Context |
|---|---|
| 12–14px | Inline with caption text, inside chips |
| 16px | Inline with body text, input adornments, menu items |
| 20px | Buttons (default), nav items |
| 24px | Primary buttons, toolbars |
| 32–40px | Tab bars (mobile), large actions |
| 48–64px | Empty state illustrations, onboarding |
Mobile tap targets require 44×44px total hit area, even if the icon glyph is 20px. Pad around the icon.
Stroke weight
Icons in a set should share one stroke weight. Mixing looks amateur.
| Style | Stroke | Use |
|---|---|---|
| Outline / linear | 1.5–2px | Modern, airy |
| Duotone | 1.5–2px + filled accent | Playful |
| Solid / filled | No stroke | Dense UIs, small sizes (< 16px read better filled) |
| Glyph (mono) | Custom per icon | Brand iconography |
Don't mix outline and filled in the same toolbar. If you want filled-active and outline-inactive, pick a library that supports both.
Pairing icons with text
Research shows icon + label outperforms icon-only for comprehension in almost every tested case. Icon-alone is acceptable only when:
- The meaning is truly universal (✕, search, back arrow).
- Space is genuinely exhausted (mobile tab bar, dense toolbar).
- The action is secondary and a tooltip on hover/focus is available.
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.
