Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by nexu-io on GitHub. Read the source before you install it.

Installation

Install the Codex Slides Deck AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/nexu-io/codex-slides/tree/master/skills/codex-slides-deck
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/nexu-io/codex-slides.git /tmp/codex-slides
mkdir -p .claude/skills
cp -r /tmp/codex-slides/skills/codex-slides-deck .claude/skills/codex-slides-deck

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Codex Slides Deck in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Codex Slides Deck on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Codex Slides Deck is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Codex Slides Deck

The canonical codex-slides sibling skill owns the complete workflow. Use the codex_slides MCP tools when available; otherwise run its self-contained CLI at ../codex-slides/scripts/codex-slides.mjs. Keep the live workspace available in the in-editor Browser whenever visual review helps.

Choose the flow

Default to the live Browser workflow: open the Codex Slides home screen, submit the request there, then operate the created project through clarify, outline confirmation, style selection, rendering, and review. Keep the Browser visible throughout.
If Browser UI submission fails, use start_project / CLI start-project to create the durable project shell, immediately open its returned URL, and continue in the UI.
Use list_scenarios / CLI scenarios when a named workflow such as business report, document-to-deck, data insights, brand application, localization, or batch generation fits. Upload required slot files and pass scenarioId, materialIds, and materialContexts into creation.
Only when the user explicitly requests an unattended/headless one-call result, call create_deck or CLI command create.
For CLI automation or recovery, call create_outline, optionally revise_outline and rank_inspiration, then render_deck; the CLI commands are outline, revise-outline, inspiration, and render.
For an existing deck, use list_projects or get_project, then choose the smallest mutation tool.

Edit with the right tool

Use edit_deck for natural-language add/rewrite/redraw/optimize requests.
Use manage_slide for deterministic add, duplicate, delete, or transition.
Use regenerate_slide for one slide.
Use restyle_deck for a whole-deck template/style change.
Use upload_material before creation, editing, or restyling when a local reference file matters.
Use upload_slide_image for a finished PNG.
Use mark_edit_slide when the user supplies an annotated PNG and wants a clean revised slide.
Use get_speaker_notes, update_speaker_notes, and generate_speaker_notes (CLI speaker-notes with get, set, or generate) for presenter-only talk tracks. These notes persist per slide, appear in the speaker window, and are embedded in PPTX export.
Use list_design_files, read_design_file, write_design_file, and upload_design_file for the project file workspace. Pass selected paths as designFilePaths when revising an outline or editing a deck.
Use get_brand_design_system then update_brand_design_system for persistent project-wide brand/style rules. Redraw only when requested.
Use start_project_run for navigation-independent chat, outline, or render work; retain the returned runId and track or cancel it explicitly.

Show and verify

Open open_codex_slides / CLI open before a new creation and keep the live workspace visible. After a programmatic mutation, navigate or reload its resource link and inspect the changed slide or flow; do not make the user open the URL manually.

Follow the exact browserHandoff.url; it can focus the changed slide, speaker notes, export, versions, Design Files, brand system, Play menu, or durable run.

Use export_deck only after the requested visual result is ready. Browser-only controls such as Play from current/beginning, the synchronized audience and presenter windows, notes editing, slide navigation, and direct on-canvas marking remain available through the live workspace.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Codex Slides Deck AI skill do?

Why use Codex Slides Deck on TypingMind?

Because you install it once and use it with any model. Codex Slides Deck is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Codex Slides Deck in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/nexu-io/codex-slides/tree/master/skills/codex-slides-deck. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Codex Slides Deck?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Codex Slides Deck?

As many as you like. As long as a model supports skills, you can use Codex Slides Deck with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Codex Slides Deck AI skill free?

Yes. It is published on GitHub by nexu-io under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
