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 | $0.00051 | $0.01576 |
| Opus 5 | $0.00026 | $0.00788 |
| Sonnet 5 | $0.00010 | $0.00315 |
| Haiku 4.5 | $0.00005 | $0.00158 |
Grade A, and why
layout 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 yesterday.
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.
This is a copy
89% identical to arrange — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Assess and improve layout and spacing that feels monotonous, crowded, or structurally weak — turning generic arrangements into intentional, rhythmic compositions.
MANDATORY PREPARATION
Invoke /impeccable — it contains design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no design context exists yet, you MUST run /impeccable teach first.
Assess Current Layout
Analyze what's weak about the current spatial design:
-
Spacing:
- Is spacing consistent or arbitrary? (Random padding/margin values)
- Is all spacing the same? (Equal padding everywhere = no rhythm)
- Are related elements grouped tightly, with generous space between groups?
-
Visual hierarchy:
- Apply the squint test: blur your (metaphorical) eyes — can you still identify the most important element, second most important, and clear groupings?
- Is hierarchy achieved effectively? (Space and weight alone can be enough — but is the current approach working?)
- Does whitespace guide the eye to what matters?
-
Grid & structure:
- Is there a clear underlying structure, or does the layout feel random?
- Are identical card grids used everywhere? (Icon + heading + text, repeated endlessly)
- Is everything centered? (Left-aligned with asymmetric layouts feels more designed, but not a hard and fast rule)
-
Rhythm & variety:
- Does the layout have visual rhythm? (Alternating tight/generous spacing)
- Is every section structured the same way? (Monotonous repetition)
- Are there intentional moments of surprise or emphasis?
-
Density:
- Is the layout too cramped? (Not enough breathing room)
- Is the layout too sparse? (Excessive whitespace without purpose)
- Does density match the content type? (Data-dense UIs need tighter spacing; marketing pages need more air)
CRITICAL: Layout problems are often the root cause of interfaces feeling "off" even when colors and fonts are fine. Space is a design material — use it with intention.
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.

layout is a skill published in the GitHub repository ReScienceLab/TrySkills (2 stars, last pushed 3mo ago), licensed MIT. It adds 51 tokens to every session and 1,576 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to arrange, differing in 12 lines, and is treated as a copy.
