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 | $0.00091 | $0.01728 |
| Opus 5.5 | $0.00036 | $0.00691 |
| Sonnet 5.5 | $0.00018 | $0.00346 |
| Haiku 4.5 | $0.00009 | $0.00173 |
Grade A, and why
canon-tooltips 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CANON · Tooltips
A tooltip is a band-aid. If you need one, the interface usually failed first. Use them, but earn them.
When a tooltip is appropriate
| Appropriate | Not appropriate |
|---|---|
| Naming an icon-only button | Explaining what a button labeled "Save" does |
| Showing full text of a truncated cell | Critical info users must see to proceed |
| Showing the exact value of a chart data point | Error messages |
| Shortcut hints ("⌘K") | Instructions needed by everyone |
| Disambiguating a date ("Posted 3d ago" → exact timestamp) | Form field labels |
| Advanced-use details secondary to the label | Primary call-to-action copy |
Critical info is never tooltip-only. If users need the info to succeed, put it in the interface.
Tooltip vs label vs popover
| Pattern | Trigger | Dismiss | Content |
|---|---|---|---|
| Tooltip | Hover, focus | Auto on mouseleave/blur | Short text, 1–2 lines max |
| Label | Always visible | N/A | Primary name of the control |
| Popover | Click, tap | Explicit dismiss | Longer content, interactive (buttons, links) |
| Disclosure | Click, tap | Toggle | Expand/collapse structured content |
Tooltips have no interactive content. No buttons. No links. If users need to click inside it, it's a popover.
Timing
| Event | Delay |
|---|---|
| Show on hover | 500–700ms delay before showing |
| Show on focus | 0ms delay — immediate |
| Hide on mouseleave | 0ms (or 50ms to allow cursor slip) |
| Hide on blur | 0ms |
| Show delay for adjacent tooltip | 0ms (if another tooltip was recently shown) |
The hover delay is critical — tooltips appearing instantly trigger every time the cursor passes by, creating visual noise. Material spec says 500ms; most modern systems use 500–700ms.
Positioning
Default: above the trigger, centered horizontally.
Fallback order when above doesn't fit:
- Below
- Right
- Left
Every tooltip needs an offset: 4–8px between tooltip edge and trigger.
Never let a tooltip cover its own trigger — users lose the context.
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.
