codex-slides-browser

Compatibility entry point for opening and operating Codex Slides in Codex's in-editor Browser, including scenario selection, Design Files, brand systems, decks, and Play mode.

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 Browser 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-browser
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-browser .claude/skills/codex-slides-browser

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

Use it in TypingMind

Enable Codex Slides Browser 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 Browser 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 Browser 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 Browser

This specialized skill remains for compatibility. The canonical codex-slides sibling skill owns the full workflow and portable CLI.

Call open_codex_slides when the MCP tool is available. Otherwise run node ../codex-slides/scripts/codex-slides.mjs open --json '<input>' from this skill directory. Pass projectId when the user named a deck; otherwise omit it for the create workspace. Use view:"scenarios" for the 24-workflow catalog, view:"design-files" plus projectId and optional filePath for project files, or view:"brand-system" plus projectId for the brand editor.
Navigate the returned resource link in the Codex in-editor Browser. Do not stop after printing the URL and do not ask the user to open it manually. Follow browserHandoff.url exactly so slide, panel, version, mode, checkpoint, conversation, and run focus are preserved.
For a new deck, always open and verify the home/create screen before any research, outline, or rendering call. Submit the topic in that UI so it creates a durable project and opens the guided workspace. Use start_project / CLI start-project only if UI submission needs a deterministic fallback, then navigate its project resource immediately.
Keep the Browser visible and operate the checkpoints in order: clarify, outline review, inspiration/style selection, render, deck review. Do not run the entire workflow invisibly in the Codex conversation.
Use direct MCP tools or the canonical skill CLI for deterministic recovery and mutations, then reload or inspect the Browser result.
Verify the visible outcome before reporting completion.

Long Deck Agent, outline, and render operations can continue after navigation. Use start_project_run, retain its runId, and use get_project_run, wait_project_run, or cancel_project_run without closing the Browser.

Use the Browser for scenario/slot selection, @ Design File references, brand system editing, Play from the current slide or the beginning, dual-window presenter mode, speaker notes editing/AI generation, slide navigation, direct on-canvas marking, layout inspection, and other visual interactions. If the Browser capability is unavailable in the current Codex surface, return the resource link and explain that limitation rather than claiming it opened.

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 Browser AI skill do?

Why use Codex Slides Browser on TypingMind?

Because you install it once and use it with any model. Codex Slides Browser 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 Browser in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/nexu-io/codex-slides/tree/master/skills/codex-slides-browser. 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 Browser?

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 Browser?

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

Is the Codex Slides Browser 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.
