codex-ppt-skill is an agent skill that turns written material such as articles, reports, papers, and notes into presentation slides made from full-page images, then packages them as PowerPoint files. It is intended for Codex and other agents that support SKILL.md workflows, including Claude Code, OpenClaw, and Hermes Agent.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 39 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.02289 |
| Opus 5.5 | $0.00011 | $0.00916 |
| Sonnet 5.5 | $0.00005 | $0.00458 |
| Haiku 4.5 | $0.00003 | $0.00229 |
Grade A, and why
codex-ppt scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex PPT
Overview
This skill creates image-based PowerPoint decks from source material. Each slide is a complete 16:9 generated image. Final images are assembled into .pptx with scripts/assemble_ppt.py.
Use this when the user wants a visually unified presentation and accepts full-slide image pages. Do not use it when every textbox, chart, or shape must remain separately editable.
Prefer the built-in image generation/editing tool. Use scripts/image_gen.py only when the built-in backend is unavailable, lacks a required capability, or the user explicitly asks for API/CLI mode.
Hard Constraints
- Read the relevant
Reference Mapfiles before each phase. This file is the orchestration contract; detailed rules live indocs/and worker prompts inprompts/. - Respect approval gates. Do not create final
deck_spec.json,speech.md, prompt jobs, slide images, or.pptxbefore the approvals indocs/workflow-gates-and-progress.md. - After the user approves the sample slide and authorizes full-deck generation, every remaining slide image job must be dispatched to a slide subagent whenever subagents are available.
- The main agent owns orchestration, prompt jobs, state recording, QA, speaker notes, and assembly. Do not silently replace available slide subagents with sequential production.
- Every final
origin_image/slide_XX.pngmust be generated by the selected image backend: built-in image generation/editing tool orscripts/image_gen.py. - Local drawing, Pillow, SVG, HTML/CSS/canvas screenshots, python-pptx/PptxGenJS layouts, and manual overlays are failure modes, not fallbacks.
- The selected image backend must stay fixed after backend confirmation. Do not let subagents switch backend for convenience.
- After sample approval, record how the approved sample was generated and pass that exact method to every slide subagent.
- Slide dispatch and result state must be recorded with the bundled scripts. Chat messages alone do not make a slide dispatched or complete.
- If a required subagent, image backend, or required-image path is unavailable, stop and report a blocker with the slide id and evidence. Do not create a lower-quality replacement.
What ships with it
39 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codex-ppt is a skill published in the GitHub repository ningzimu/codex-ppt-skill (7,134 stars, last pushed 7d ago), licensed MIT. It adds 27 tokens to every session and 2,289 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
