Token cost

What it costs to keep this loaded

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.

Fable 5.1 $0.00079 $0.01887

Security

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 10d 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.

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:

  1. The meaning is truly universal (✕, search, back arrow).
  2. Space is genuinely exhausted (mobile tab bar, dense toolbar).
  3. 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.
