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 | $0.00077 | $0.01473 |
| Opus 5.5 | $0.00031 | $0.00589 |
| Sonnet 5.5 | $0.00015 | $0.00295 |
| Haiku 4.5 | $0.00008 | $0.00147 |
Grade A, and why
canon-buttons 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Buttons
A button is a verb. If the element navigates, it's a link. This distinction is not cosmetic — screen readers announce them differently, middle-click behaves differently, right-click behaves differently.
The button vs link rule
| Task | Element |
|---|---|
| Submits form, triggers action, toggles state, opens modal, plays media | <button> |
| Navigates to a URL, scrolls to an anchor, opens new tab | <a href> |
Styling doesn't change semantics. A <div onclick> is never correct.
Hierarchy — one primary per screen
| Level | Appearance | Rule |
|---|---|---|
| Primary | Filled, brand color | One per screen. The single most important action. |
| Secondary | Outlined or tonal fill | Alternative action. Cancel, back, alt-submit. |
| Tertiary / Ghost | Text only, no border | Low-priority. Breadcrumb actions, dismiss. |
| Destructive | Red filled or red outlined | Delete, revoke. Appears only when the action is available. |
If you feel you need two primaries, one of them isn't primary.
Sizing
| Size | Height | Padding-X | Font size | Use |
|---|---|---|---|---|
| XS | 24px | 8px | 12px | Inline table actions only |
| SM | 32px | 12px | 13px | Toolbars, dense UIs |
| MD | 40px | 16px | 14px | Default. |
| LG | 48px | 20px | 16px | Hero CTAs, mobile-primary |
| XL | 56px | 24px | 18px | Marketing only |
Mobile floor: 44×44px hit target. Below that, violates Apple HIG and fails WCAG 2.5.5.
Required states
A button must look visibly different in all six states. Missing any = incomplete.
- Default — resting
- Hover —
cursor: pointer, subtle elevation or fill change - Active — press feedback (transform: scale(0.98) or filter darken)
- Focus-visible — 2–3px outline offset 2px, contrast 3:1 minimum
- Disabled — 40–50% opacity,
cursor: not-allowed, no hover change - Loading — spinner replaces label OR sits beside it, button stays the same width
Loading state
<button disabled aria-busy="true">
<span class="spinner" aria-hidden="true"></span>
<span>Saving…</span>
</button>
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.
