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 | $0.00066 | $0.00661 |
| Opus 5.5 | $0.00026 | $0.00264 |
| Sonnet 5.5 | $0.00013 | $0.00132 |
| Haiku 4.5 | $0.00007 | $0.00066 |
Grade A, and why
canon-illustrations 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Illustrations
An illustration earns its space by explaining something words can't, or by giving an emotional moment visual weight. Decorative illustrations that do neither are clutter.
When illustrations help
| Context | Purpose | Effective? |
|---|---|---|
| Empty state | Softens the blank page, invites action | Yes — if paired with a CTA |
| Error page (404, 500) | Humanizes the failure | Yes — keeps it light |
| Onboarding | Explains a concept visually | Yes — if the concept is spatial/abstract |
| Feature marketing | Shows the benefit | Yes — if it's specific, not generic |
| Success confirmation | Celebration moment | Maybe — keep it subtle |
| Every card in a grid | Decoration | No — visual noise |
| Loading screen | Distraction | No — use skeleton |
Style rules
- One illustration style per product. Mixing styles (flat + 3D + hand-drawn) looks like different products.
- Consistent stroke weight, color palette, and level of detail across all illustrations.
- Match the brand voice. Playful brands get whimsical illustrations. Enterprise tools get cleaner, geometric ones.
- No stock illustration without customization. Generic "person at laptop" illustrations signal low effort.
Sizing
| Placement | Size |
|---|---|
| Spot illustration (empty state) | 120–200px |
| Feature explanation (inline) | 200–320px |
| Hero / marketing | 400–600px |
| Error page | 200–320px |
Never let an illustration dominate the page over the content or CTA.
Accessibility
- Illustrations are decorative unless they convey information.
- Decorative:
aria-hidden="true"oralt="". - Informative:
alt="Description of what the illustration shows". - Don't rely on the illustration to convey critical information.
Anti-patterns
| Anti-pattern | Why it fails |
|---|---|
| Illustration on every empty state regardless of context | Noise |
| Stock illustrations with inconsistent styles | Looks patchwork |
| Giant hero illustration pushing content below the fold | Users came for content, not art |
| No alt text on informative illustrations | Accessibility fail |
| Animation on illustrations without reduced-motion respect | Motion sensitivity |
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.
