simple-deck

simple-deck is a skill for Claude Code, Codex from mphinance/alpha-skills. It costs 74 tokens per session (1,097 once invoked), scanned A, a copy of simple-deck, MIT.

A recipe for a single-file HTML presentation with horizontal swipe navigation. HTML is the language used to structure web pages; this deck uses a starter file and a library of slide layouts for pitches, product overviews, or study material.

In plain words
What is it for?
Use it to create a lightweight browser-based pitch deck, product presentation, or set of study slides in one HTML file.
Why use it?
It avoids rebuilding slide navigation and common layout patterns for every web presentation. The supplied starter also handles several scrolling and focus problems in embedded pages.

Token cost

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.

Security

Grade A, and why

simple-deck 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 1mo 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.

Simple Deck Skill

Produce a single-file horizontal-swipe HTML deck using the seed and layout library.

Resource map

├── SKILL.md                ← you're reading this
├── assets/

    └── checklist.md        ← P0/P1/P2 self-review (rhythm spot-check at bottom)

Workflow

Step 0 — Pre-flight

  1. Read assets/template.html end-to-end through the <style> block AND the <script> block. The script solves five iframe-specific bugs (real scroller detection, dual capture-phase listeners, auto-focus, no scrollIntoView, position persistence) — do not rewrite it.
  2. Read references/layouts.md so you know the 8 layouts. Pay special attention to the "Theme rhythm" section — it's the rule that prevents the deck from feeling sleepy.
  3. Read the active DESIGN.md — map its tokens to the six :root variables in the seed.

Step 1 — Copy the seed

Copy assets/template.html to the project root as index.html. Replace the six :root variables with the active design system's tokens. Replace the page <title>.

Step 2 — Decide slide count + theme rhythm BEFORE writing any slide

Default: 6 slides unless the brief says otherwise.

Audience / format Slides
Product overview / lightning talk (5–10 min) 6
Pitch deck (15 min) 8–10
Investor update / longer talk (20–30 min) 12–18

Then write out the rhythm before any HTML — for example, 8 slides:

01  hero light center  Cover
02  light              Problem
03  hero dark center   Big stat
04  light              Three points
05  dark               Pipeline
06  hero light center  Quote
07  light              Before / after
08  hero dark center   Ask

A healthy sequence has:

  • No 3+ same theme in a row
  • ≥ 1 hero dark AND ≥ 1 hero light (for 8+ slides)
  • Alternating breath every 3–4 slides

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.
