Verify that Codex Slides changes are durably reflected in project state and visibly reflected in the exact Codex Browser slide, panel, version, checkpoint, or presentation surface. Use after creation, rendering, editing, restyling, mark edits, speaker-note changes, version restores, or export.

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 Verification 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-verification
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-verification .claude/skills/codex-slides-verification

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

Use it in TypingMind

Enable Codex Slides Verification 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 Verification 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 Verification 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 Verification

Use two signals before reporting a presentation task complete:

Read canonical project state with get_project, and read a named durable job with get_project_run or wait_project_run when a runId was returned.
Follow the returned browserHandoff and inspect the exact visible result in the Codex in-editor Browser.

Verification sequence

Confirm the project id rather than guessing from a similar title.
For a durable run, require a terminal complete status. Treat error and cancelled as incomplete; a timed-out wait leaves the run active.
Confirm the expected page count, changed slide indexes, rendered images, transitions, speaker notes, current workflow stage, and current deck version.
Open the exact handoff returned by the mutation. Preserve its slide, panel, version, mode, conversation, checkpoint, and run query parameters.
In Browser, confirm the intended slide or panel is focused and the visible result matches the request. Do not treat a JSON response alone as visual QA.
Export only after the current or explicitly selected version passes review.

If the in-editor Browser is unavailable, use the project state and persisted slide-image endpoints as structural evidence, return the exact handoff URL, and state that visible Browser verification remains outstanding.

For cross-surface changes, also verify that refreshing or reopening the same project preserves the run result and deep-link focus.

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 Verification AI skill do?

Why use Codex Slides Verification on TypingMind?

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

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

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 Verification?

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

Is the Codex Slides Verification 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.
