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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.07871 |
| Opus 5 | $0.00023 | $0.03936 |
| Sonnet 5 | $0.00009 | $0.01574 |
| Haiku 4.5 | $0.00005 | $0.00787 |
Grade A, and why
dark-mode-design-expert 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 11d 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.

The Science of Dark Mode
Why Dark Mode Exists
| Factor | Light Mode | Dark Mode | Winner |
|---|---|---|---|
| OLED Battery | 100% baseline | 39-47% savings at max brightness | Dark |
| Low Light Comfort | Eye strain, fatigue | Reduced glare | Dark |
| Bright Environment | Better readability | Washed out | Light |
| Astigmatism Users | Easier to read | Halation effect | Light |
| Focus/Immersion | Standard | Content pops forward | Dark |
| Sleep Hygiene | Blue light exposure | Reduced blue light | Dark |
Key Insight: Dark mode isn't universally better—it's contextually better. The best systems respect user preference AND adapt to environment.
Contrast Requirements (WCAG 2.1)
| Element Type | Minimum Ratio | Target Ratio | Notes |
|---|---|---|---|
| Body text | 4.5:1 | 7:1+ | AAA preferred for readability |
| Large text (≥24px) | 3:1 | 4.5:1+ | Headlines, hero text |
| UI components | 3:1 | 4.5:1+ | Borders, icons, focus rings |
| Disabled elements | None required | 2.5:1 | UX consideration |
| Decorative | None required | - | Pure aesthetic elements |
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
