html-slide-plan

html-slide-plan is a skill for Claude Code, Codex from bytonylee/future-slide. It costs 35 tokens per session (257 once invoked), scanned A, original, Apache-2.0.

A planning step for deciding the story, order, content, and layout of each slide in an HTML deck. HTML slides are presentations built with web-page files that can be edited like a website.

In plain words
What is it for?
Use it to create a slide_plan.json file containing deck metadata, content mapping, the story arc, and implementation guidance for every slide.
Why use it?
It settles the structure before coding, helping prevent missing evidence, weak slide order, or layouts that are difficult to build with HTML and CSS.

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

html-slide-plan 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.

What it actually says

HTML Slide Plan

Use this skill for commands like:

  • $html-slide-plan
  • "plan the HTML slide deck"
  • "create slide_plan.json for web slides"
  • "decide slide order before implementation"

Goal

Create slide_plan.json: the deck story, slide order, content mapping, and HTML-friendly layout direction for each page.

Inputs

  • DESIGN.md
  • user files or source material
  • user deck goal, audience, language, and constraints

Required Output

Return valid JSON only. Include:

  • deck metadata
  • design dependency
  • content inventory
  • story arc
  • ordered slides
  • per-slide role, page family, core message, evidence, recommended HTML layout, and header/body/footer plan

Hard Rules

  • Do not write HTML yet.
  • Do not create image-generation prompts.
  • Use DESIGN.md as visual constraints.
  • Prefer layouts that can be built cleanly with semantic HTML and CSS.
  • Stop after slide_plan.json unless the user explicitly asks to continue.

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.
