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 | $0.00070 | $0.05523 |
| Opus 5 | $0.00035 | $0.02762 |
| Sonnet 5 | $0.00014 | $0.01105 |
| Haiku 4.5 | $0.00007 | $0.00552 |
Grade A, and why
frontend-slides 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 4d 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 — 331 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Slides Skill
Create zero-dependency, animation-rich HTML presentations that run entirely in the browser. This skill helps non-designers discover their preferred aesthetic through visual exploration ("show, don't tell"), then generates production-quality slide decks.
Reference files: When generating CSS, image processing, PPT extraction, HTML structure, edit button, or animation code, read the corresponding file under reference/ (and STYLE_PRESETS.md for presets and CSS Gotchas) so output is correct and complete.
🧠 Core Design Philosophy
1. Visual Style & Material
Principle: Form follows function. All visual decisions (color, layout, material) must serve the user's mental model and business goals.
| Style Position | Use Cases | Core Characteristics |
|---|---|---|
| Future & Depth | Frontier exploration, tech product launches | Frosted glass + dark mode, halos and transparency for layering |
| Efficiency & Speed | Professional tools, data dashboards | Clean flat style + Bento UI, clear boundaries, modular |
| Trust & Professional | Finance, formal presentations, enterprise solutions | Swiss minimalism, generous whitespace, relies on typography and strict grids |
| Care & Resonance | Humanities, lifestyle, brand stories | Low-saturation natural colors + extreme rounding, ultra-soft diffuse shadows |
| Immersion & Expression | Entertainment, narrative, creative showcases | Skeuomorphic materials + high-contrast emotional colors, breaks conventional grids |
Style Selection Rules:
- Solution deck / presales proposal → Trust & Professional (Swiss Modern) or Efficiency & Speed (Bento UI)
- Product launch / tech showcase → Future & Depth (Dark Botanical / Electric Studio)
- Brand story / humanities content → Care & Resonance (Pastel Geometry / Vintage Editorial)
- Creative proposal / marketing campaign → Immersion & Expression (Neon Cyber / Creative Voltage)
2. Spatial & Typography Organization
- Density Hierarchy: Density is inversely proportional to importance. Core focus areas need low density / large margins. Data lists need high density / small margins.
- Typography System:
- Prefer modern sans-serif fonts (Clash Display, Satoshi, DM Sans)
- Establish significant weight and size contrast between headings and body
- Body line-height:
leading-[1.5]orleading-[1.6]for visual breathability
- Font Size Constraints:
- Minimum readable size:
12px(annotations only) - Standard body:
14px/16px - Headings use
clamp()for responsive scaling
- Minimum readable size:

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.

frontend-slides is a skill published in the GitHub repository zai-org/Synapse (438 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 70 tokens to every session and 5,523 once invoked, about $0.0003 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.
