slide-master: Skill for Claude Code

.claude/skills/ppt-master/SKILL.md

ppt-master is a skill for Claude Code from byungjunjang/slide-master. It costs 111 tokens per session (26,004 once invoked), scanned B, original, MIT.

A pipeline for creating or rebuilding presentation pages as SVG graphics and exporting them to PowerPoint files.

In plain words
What is it for?
Useful for creating decks from source material, redesigning PowerPoint files, and generating or refining reusable SVG-based presentation layouts.
Why use it?
It coordinates planning, visual generation, previewing, quality checks, and export so the slide design remains represented in the source graphics.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions subagents; names the AskUserQuestion tool.

This is byungjunjang/slide-master's own configuration. It tells Claude Code how to work on slide-master itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything slide-master configures →

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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 1,029 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPT Master Skill

Entry precondition — route first: Before loading this full file, workflows/routing.md has selected the main SVG family, or another workflow has explicitly handed off to shared SVG steps. Strict 1:1 selection loads beautify-pptx.md first and loads this file only at that workflow's explicit handoff. Raw template fill and finished-PPTX native enhancement do not load or inherit this file.

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

Main SVG Pipeline: Source Document → Create Project → [Template] → Strategist Structured Plan → [Image_Generator] → Executor Live Preview → Quality Check → Post-processing → Export

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/ On-demand derived, self-contained SVG visual preview (deferred by default — generated by Step 7.2 only when SVG previews / manual insertion are requested). 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. The ppt-template-fill skill, native-enhance-pptx, animations, transitions, speaker notes, narration, and package relationships are not required to round-trip through SVG.

What ships with it

Changes

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.
