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 | $0.00022 | $0.00735 |
| Opus 5 | $0.00011 | $0.00367 |
| Sonnet 5 | $0.00004 | $0.00147 |
| Haiku 4.5 | $0.00002 | $0.00073 |
Grade A, and why
ui-page 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 2d 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.

UI Page
Overview
Part of StyleSeed, this skill scaffolds a complete page or screen using the Toss seed's mobile-first composition rules. It keeps page structure consistent by building on the existing shell, top bar, bottom navigation, and card rhythm instead of producing disconnected sections.
When to Use
- Use when you need a new page in a Toss-seed app
- Use when you want a consistent page shell, spacing, and navigation structure
- Use when you are adding a new product flow and need a solid starting layout
- Use when you want to stay mobile-first even if the project later expands to larger breakpoints
How It Works
Step 1: Inspect the Existing Shell
Read the current page scaffolding patterns first, especially:
- page shell
- top bar
- bottom navigation
- representative pages using the same route family
Step 2: Define the Page Purpose
Clarify:
- the page name
- the primary user question the screen answers
- the top one or two actions the user should take
Every screen should have one dominant purpose.
Step 3: Use the Information Pyramid
Lay out the page from highest importance to lowest:
- Hero or top summary
- KPI or key actions
- detail cards or supporting modules
- lists, history, or secondary content
Avoid repeating the same section type mechanically from top to bottom.
Step 4: Apply the Toss Layout Rules
Default layout choices:
- mobile viewport width around
max-w-[430px] - page background on
bg-background - horizontal padding around
px-6 - section rhythm with
space-y-6 - generous bottom padding if a bottom nav is present
- cards using semantic surface tokens, rounded corners, and light shadows
Step 5: Compose Instead of Rebuilding
Use existing ui/ and patterns/ components wherever possible. New pages should primarily orchestrate existing building blocks, not recreate them.
Step 6: Account for Real Device Constraints
- handle safe-area insets
- avoid horizontal overflow
- keep interactive clusters thumb-friendly
- ensure long content scrolls cleanly without clipping the bottom navigation
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.

ui-page is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 22 tokens to every session and 735 once invoked, about $0.0001 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 2026-09-03.
