ppt-master

ppt-master is a skill for Claude Code, Codex from open-octo/octo-agent. It costs 76 tokens per session (21,410 once invoked), scanned B, original, MIT.

A presentation-generation system that turns source material into SVG pages and exports them as PowerPoint files. SVG is a format for describing scalable page graphics; source material can include PDFs, Word documents, URLs, or Markdown.

In plain words
What is it for?
Use it to create presentations from documents or web pages, plan slide content, generate and place images, preview pages, run quality checks, and export the result to PPTX.
Why use it?
It provides a pipeline for turning reference content into presentation pages without manually laying out every slide. It also includes review and export stages for producing a PPTX deck.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is # ../images/); the spec + template SVGs + other non-image assets stay in.

Good fit Use it to create presentations from documents or web pages, plan slide content, generate and place images, preview pages, run quality checks, and export the result to PPTX.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

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.

Security

Grade B, and why

ppt-master scanned grade B with 1 finding 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 10d ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/analyze_images.py, scripts/animation_config.py, scripts/batch_validate.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

PPT Master Skill

AI-driven multi-format SVG content generation system. Converts source documents into high-quality SVG pages through multi-role collaboration and exports to PPTX.

Core Pipeline: Source Document → Create Project → [Template] → Strategist → [Image_Generator → delegated to the image-gen skill] → Executor Live Preview → Quality Check → Post-processing → Export

🎨 Images are delegated to the image-gen skill. All AI image generation, web image search, and sheet slicing — and the image-style catalogs (image-generator.md, image-base.md, image-searcher.md, image-palettes/, image-renderings/, image-type-templates/) and scripts (image_gen.py, image_search.py, slice_images.py) — live in the separate general-purpose image-gen skill, not here. Whenever this skill or any of its references (including strategist.md's image-style GATEs and Step 5) tells you to read one of those catalogs or run one of those scripts, load the image-gen skill and use its copies. ppt-master keeps only the deck-side pieces: the resource list (design_spec.md §VIII), image placement on the page, the images/image_prompts.json handoff manifest, LaTeX formulas, and analyze_images.py / rotate_images.py image-fact tooling. Full handoff contract: Step 5.

SVG Page-Design Boundary

Scope Contract
Any route that authors or regenerates slide visuals through SVG svg_output/ is the complete page-design source: every visible text, image, shape, chart/table fallback, and layout element that should appear on the exported slide is present in that page SVG or referenced by it.
Templates, design_spec.md, and spec_lock.md Authoring/control inputs. They guide SVG creation but MUST NOT supply visible slide content that is absent from the completed SVG during export.
Semantic SVG markers Minimal rendering-neutral compiler hints used only after existing Layout/Layer/Placeholder/Native metadata has been considered. They never replace native SVG geometry, text, styles, grouping, or asset references.
svg_final/ Mandatory derived, self-contained SVG visual preview. It may be opened directly or inserted into PowerPoint as an SVG picture, but it is not a supported PPTX source and carries no manual Convert-to-Shape compatibility contract.
SVG-to-PPTX export The only supported generated-PPTX route reads svg_output/ and maps its content through the project converter to DrawingML/native objects. It may reorganize represented content into Master/Layout/Slide structure but MUST NOT invent new visible page content.
Direct PPTX and presentation-behavior workflows Remain separate. template-fill-pptx, native-enhance-pptx, animations, transitions, speaker notes, narration, and package relationships are not required to round-trip through SVG.

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.

ppt-master is a skill published in the GitHub repository open-octo/octo-agent (97 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 21,410 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (subtle steering). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
