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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 43 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00069 | $0.01989 |
| Opus 5 | $0.00034 | $0.00994 |
| Sonnet 5 | $0.00014 | $0.00398 |
| Haiku 4.5 | $0.00007 | $0.00199 |
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 useslides-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
--referenceimages 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>
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.

slides-grab-image is a skill published in the GitHub repository NomaDamas/slides-grab (1,206 stars, last pushed 3d ago), licensed MIT. It adds 69 tokens to every session and 1,989 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
