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 | $0.00078 | $0.00749 |
| Opus 5 | $0.00039 | $0.00375 |
| Sonnet 5 | $0.00016 | $0.00150 |
| Haiku 4.5 | $0.00008 | $0.00075 |
Grade A, and why
information-density 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.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Information Density
Design interfaces that let users control how much information they see at once — because the right density for a power user scanning 200 rows is the wrong density for someone who needs space to process each item.
The Density Spectrum
Compact
- Minimal spacing, smaller text, more items visible
- Suits: power users, data-heavy tasks, large screens
- Risks: overwhelming for cognitive disabilities, hard to tap on touch devices, hard to scan for low vision
Comfortable (Default)
- Moderate spacing, standard text size, balanced visibility
- Suits: most users in most contexts
- This should be the default — optimise for this first
Spacious
- Generous spacing, larger text, fewer items visible
- Suits: cognitive disabilities, low vision, touch devices, new users, stressful contexts
- Risks: requires more scrolling for experienced users
Design Patterns
Density Controls
- Offer 2–3 density options (compact, comfortable, spacious)
- Use clear labels — not just icon toggles
- Apply density change immediately (no page reload)
- Remember the preference across sessions
- Place the control near the content it affects
What Changes With Density
- Vertical spacing between items
- Horizontal padding within items
- Font size (within accessible range — never below 0.875rem)
- Line height (within accessible range — never below 1.5 for body)
- Amount of metadata shown per item
- Thumbnail or preview sizes
- Number of columns in grid layouts
What Should NOT Change With Density
- Content meaning — no information should be lost at any density
- Accessibility — every density level must meet WCAG requirements
- Interaction targets — minimum 44×44px on touch regardless of density
- Heading structure — structure stays consistent
- Keyboard navigation — tab order stays logical
Density by Context
- Lists and feeds: control row height and visible metadata
- Data tables: control row padding and visible columns
- Dashboards: control card size and spacing
- Inboxes: control preview length and row height
- Calendars: control event detail visibility
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.

information-density is a skill published in the GitHub repository Owl-Listener/inclusive-design-skills (98 stars, last pushed 3mo ago), licensed MIT. It adds 78 tokens to every session and 749 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
