slides-grab-image

slides-grab-image is a skill for Codex from NomaDamas/slides-grab. It costs 69 tokens per session (1,989 once invoked), scanned A, original, MIT.

A presentation workflow that generates each slide as a complete raster image while following a supplied reference template. A raster image is a finished picture rather than editable slide text and objects.

In plain words
What is it for?
Use it to create slides one at a time from matching reference pages, replacing the original content while preserving the template’s visual form.
Why use it?
It is intended for cases where matching an existing deck’s layout, colours, fonts, and visual density matters more than keeping the content editable.

About the project

slides-grab is a tool for creating and editing presentations as HTML and CSS files, with an editor that lets coding agents work on selected parts of a slide and export decks to PDF or experimental PPTX files. It is for people generating presentations with Claude Code, Codex, and related agents. The catalogue entries provide skills, agents, and instructions for its presentation workflow.

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

slides-grab-image 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 10d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

slides-grab Image Skill

Generate whole-slide raster images where the generated PNG is the slide. Each slide is generated individually with slides-grab image, passing the matching reference template page image(s) via --reference so the model reproduces the template's layout, colors, fonts, and density — only swapping in the new slide's content. Use this pipeline when the user wants to match an existing corporate template, filled deck, or brand form visually.

Mode signal

The plan stage records mode: image-native in slide-outline.md. The user typically provides a reference template (PPTX, PDF, HTML examples) and says "make slides in this form."

Core rule: reference-guided per-slide generation

  • Generate one slide at a time with slides-grab image. Do NOT use slides-grab generate-images (the batch command auto-assembles garbage prompts from markdown and produces inconsistent output).
  • Always pass at least one reference template page image via --reference <path> (repeatable). The reference page(s) must be the same slide-type (cover, content, closing) from the source template. The model must copy the reference's layout, color bands, typography hierarchy, whitespace, and density — only the text content and any embedded photos change.
  • The prompt must explicitly instruct: "Follow the reference image's layout, composition, color palette, and typography hierarchy exactly. Keep the same band positions, spacing, and visual rhythm. Only replace the text content and photos with the new slide's content below."
  • Pass any real photos/assets to embed as additional --reference images so the model can place them into the template layout.

Prompt structure (use this pattern)

slides-grab image \
  --prompt "Follow the reference image layout exactly — same color bands, same typography hierarchy, same spacing and density. This is a [cover/content/closing] slide. Replace the text with: Title: '<new title>'. Body: '<new body text>'. Bullets: <bullet list>. Keep the template's visual style, fonts, and color palette. Render all text sharp and legible. 16:9, 720pt × 405pt." \
  --slides-dir <path> \
  --reference <template-page-cover.png> \
  --reference <real-photo-to-embed.png>
