What is the Codex PPT SkillProof Score?

8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.

How do I install Codex PPT?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Codex PPT with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Codex PPT

Test report

Verdict: Works with setup
Score: 8.0/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 78e4371

The assembly pipeline is real and works: with python-pptx and Pillow installed, assemble_ppt.py packed three 1920x1080 images into a valid 16:9 three-slide PPTX. The headline value, though, is AI-generated unified slide imagery, which needs an image backend (built-in image tool or a paid OpenAI-compatible key) that was unavailable here, so no delta versus a no-skill baseline could be measured. Well-engineered orchestration with approval gates, subagent dispatch and QA, and its API key only ever goes to the user-configured OpenAI or atlascloud endpoint.

What Codex PPT does

Turns an article, report, paper or outline into a visually unified PowerPoint where every slide is a full 16:9 generated image, with approval gates, per-slide subagent dispatch, QA and a Python assembler. Requires an image-generation backend (a built-in image tool or an OpenAI-compatible/gpt-image API key). Use it for image-first decks, not when shapes must stay individually editable.

How to install Codex PPT

git clone https://github.com/ningzimu/codex-ppt-skill.git
mkdir -p ~/.claude/skills
cd codex-ppt-skill && cp -r skills/codex-ppt ~/.claude/skills/codex-ppt

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
