What it does

Slides Grab HTML is an agent skill from NomaDamas/slides-grab. HTML-mode presentation pipeline usable in Codex and Claude Code. Build semantic slide-XX.html files, generate bespoke hero/accent imagery with slides-grab image, run the design gate, and export. Use when the deck needs editable, searchable, accessible text or when no existing template must be matched pixel-for-pixel.

Its SKILL.md is about 1.6k 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: Best harness + editor + linter for generating slides in Claude Code / Codex - Claude Design Open Source Alternative. The licence is MIT.

When your agent uses it

The deck needs editable
Accessible text
No existing template must be matched pixel-for-pixel

Example prompts

“/slides-grab-html”

Requirements

A credential in OPENAI_API_KEY
A credential in GOOGLE_API_KEY

Workflow steps

3 steps, taken from the step headings in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 49bdaed. 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
Shell commands in SKILL.md call:
- codex
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- cdn.jsdelivr.net
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- OPENAI_API_KEY
- GOOGLE_API_KEY
- GEMINI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Slides Grab HTML loads about 1.6k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 744 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~84
When it runs · the whole SKILL.md, loaded when a task matches: ~1.6k

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.

metadata.short-description: Semantic HTML slide pipeline with bespoke imagery

slides-grab HTML Skill

Build semantic slide-XX.html files where text is real HTML (selectable, editable, accessible) and imagery is generated as supporting accent/hero assets — never as whole-slide rasters. Use this pipeline when the user wants a deck they can edit, when slides contain charts or diagrams, or when no existing template demands pixel-perfect visual matching.

Mode signal

The plan stage records mode: html in slide-outline.md. If no mode is recorded, default to this pipeline.

Bespoke imagery rule

Use slides-grab image to generate individual hero/accent images that sit beside or behind semantic text inside an HTML slide. The generated image is a supporting visual — text and layout stay in HTML/CSS.
A bespoke image prompt describes the accent visual only — the atmospheric mood, the hero illustration, the background texture — not the slide's title, body copy, or layout. Let HTML handle text and layout.
Good prompt: "Atmospheric dawn horizon, cyan and silver tones, dreamy Y2K mood, no text, 16:9" — describes a hero background.
If you instead need the generated image to BE the whole slide (title, body, layout burned into the raster), use the image-native pipeline (../slides-grab-image/SKILL.md) — semantic HTML is the wrong tool for that.

Workflow

Stage 1 — Plan

Use the installed slides-grab-plan skill.

Take topic, audience, and tone.
Run slides-grab list-styles, shortlist 2–3 bundled styles, get explicit approval. Optionally offer slides-grab preview-styles. If none fit, propose a custom direction. If the user provides a reference template/PDF/PPTX for color tokens only (not pixel-perfect matching), import it with slides-grab import-template and record style: template-pack — the template pack supplies design tokens, but slides stay semantic HTML.
Record mode: html in slide-outline.md meta.
Present outline, revise until approved.

Stage 2 — Design

Use the installed slides-grab-design skill.

Read approved slide-outline.md, load the style spec (src/design-styles-data.js for bundled ids, slides-grab show-design for DESIGN.slides.md, or .slides-grab/template-pack.json for imported packs).
Write a visual thesis, content plan, system declaration, and design tokens before generating slides.
Generate slide-XX.html semantic HTML files with 2-digit numbering in --slides-dir.
Bespoke imagery: when a slide needs a hero/accent image, run slides-grab image --prompt "<accent-visual prompt>" --slides-dir <path>. The default codex provider reuses the local Codex ChatGPT login (~/.codex/auth.json — run codex login once; no API key required). Save under <slides-dir>/assets/. To guide the style, pass reference images with --reference <path> (repeatable). Optional providers: --provider openai (OpenAI gpt-image-2 via OPENAI_API_KEY), --provider nano-banana (Google gemini-3-pro-image-preview via GOOGLE_API_KEY/GEMINI_API_KEY, supports --image-size 2K|4K). If credentials are unavailable, fall back to web search + download into <slides-dir>/assets/.
Diagrams: for complex diagrams (architecture, workflows, relationship maps), use tldraw via slides-grab tldraw, store under <slides-dir>/assets/.
Charts: default to Chart.js (<script src="https://cdn.jsdelivr.net/npm/chart.js"></script>), start from templates/chart.html, keep animation: false, responsive: true, maintainAspectRatio: false, wrap <canvas> in a stable container. slides-grab validate reports empty-canvas for unpainted canvases.
Video: store under <slides-dir>/assets/, prefer poster="./assets/<file>". Use slides-grab fetch-video or yt-dlp for web sources.
Icons: prefer Lucide before emoji.
Run slides-grab validate --slides-dir <path>. Auto-fix failures until it passes.
Run the design gate (../slides-grab-design/references/design-gate.md): capture PNG evidence, run Pass A (System Contract) + Pass B (Audience Impact), synthesize verdict. Resolve all Critical findings, re-render, re-review until Proceed. Record with slides-grab design-gate --slides-dir <path> --verdict proceed --pass-a-report <a.md> --pass-b-report <b.md>.
Launch the HTML editor: slides-grab edit --slides-dir <path>. For chart decks, also run slides-grab build-viewer and confirm charts render in viewer.html.

Show full SKILL.md (193 more words)Show less

Stage 3 — Export

Use the installed slides-grab-export skill. Requires a fresh Proceed gate receipt.

Widescreen → slides-grab pdf --slides-dir <path> --output <name>.pdf.
Per-slide PNG → slides-grab png --slides-dir <path> --output-dir <path>/out-png --resolution 2160p.
Card-news → slides-grab png --slide-mode card-news (see ../slides-grab-card-news).
PPTX/Figma (experimental / unstable) → slides-grab convert / slides-grab figma.

Rules

Keep slide size 720pt × 405pt.
Keep semantic text tags (p, h1-h6, ul, ol, li). Never put text directly in <div>/<span>.
Backgrounds only on <div>; text only in semantic tags.
No CSS gradients — use flat fills; rasterize gradients to PNG with Sharp if needed.
Put local images/videos under <slides-dir>/assets/, reference as ./assets/<file>.
Allow data: URLs when a slide must be self-contained; never leave remote http(s):// image URLs in saved HTML.
Prefer Lucide for iconography; avoid emoji unless the brief explicitly asks.
Keep body copy ≥14pt on a 720pt × 405pt slide; 10pt absolute floor.
Avoid AI slop tropes (aggressive gradient backgrounds, left-border accent cards, SVG-drawn imagery, generic font stacks, generic 3×2 icon-plus-blurb grids).
Do not present slides for review until slides-grab validate passes.
Do not advance to export while any Critical design-gate finding is unresolved.
