Best harness + editor + linter for generating slides in Claude Code / Codex - Claude Design Open Source Alternative
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.
This repository also configures its own agents. See what slides-grab tells them →

Skill Claude CodeCodex
Stage 3 conversion skill usable in Codex and Claude Code. Convert approved HTML slides to PDF or per-slide PNG reliably, and to experimental / unstable PPTX/Figma outputs on a best-effort basis.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
Image-native presentation pipeline usable in Codex and Claude Code. Generate whole-slide raster images one slide at a time with slides-grab image, passing the reference template page as --reference so the model copies the layout and style and only swaps the content. Use when visual fidelity to an existing template…
Skill Claude CodeCodex
Stage 1 planning skill usable in Codex and Claude Code. Build and iterate slide-outline.md until explicit user approval.
Skill Claude CodeCodex
End-to-end presentation workflow usable in Codex and Claude Code. Routes the user request to the HTML-mode or image-native-mode sub-skill, then runs the shared plan, design, and export stages. PDF and per-slide PNG are preferred; PPTX/Figma export is experimental / unstable.
