What it does

HTML Slide is an agent skill from humantonylee/future-slide. End-to-end HTML slide workflow. Trigger when the user wants a slide deck as editable HTML/CSS/JS from a reference design, source files, and a deck prompt. Runs design, plan, prompt, and render stages in order.

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Documents & Office, covering Slides and decks. The repository describes itself as: The workflow for disciplined slide generation. Extract design, plan the deck, render with consistency. The licence is Apache-2.0.

When your agent uses it

  • The user wants a slide deck as editable HTML/CSS/JS from a reference design
  • Tasks that involve Slides and decks

Example prompts

  • “/html-slide”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Extract DESIGN.md from the reference visual.
  2. Build slide_plan.json from DESIGN.md, user files, and the deck request.
  3. Build html_slide_prompts.json with per-slide implementation instructions.
  4. Implement an HTML deck and verify it in a browser when possible.

What it can do on your machine

Read from SKILL.md and the folder at commit 26914e8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

HTML Slide loads about 362 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 157 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~362

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
End-to-end HTML slide workflow. Trigger when the user wants a slide deck as editable HTML/CSS/JS from a reference design, source files, and a deck prompt. Runs design, plan, prompt, and render stages in order.

HTML Slide Workflow

Use this skill when the user asks for the full HTML slide workflow, for example:

  • $html-slide
  • "create an HTML slide deck"
  • "make browser-rendered slides from this reference"
  • "build editable web slides"

This is the HTML orchestrator. If the user asks for only one step, use the matching step skill instead:

  • $slide-design for DESIGN.md
  • $html-slide-plan for slide_plan.json
  • $html-slide-prompt for html_slide_prompts.json
  • $html-slide-render for final HTML/CSS/JS slide files

Required Sequence

Run these stages in order:

  1. Extract DESIGN.md from the reference visual.
  2. Build slide_plan.json from DESIGN.md, user files, and the deck request.
  3. Build html_slide_prompts.json with per-slide implementation instructions.
  4. Implement an HTML deck and verify it in a browser when possible.

Output Contract

The full workflow should leave these files in the workspace:

  • DESIGN.md
  • slide_plan.json
  • html_slide_prompts.json
  • an HTML slide deck, usually under slides-html/

Routing Rule

If the user asks for GPT native image generation, PNG pages, or imagegen output, use the gpt-image-slide skill family instead.
