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 A, and why

slide-making-skill 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 7d 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.

PptxGenJS Slide Making Skill

This skill teaches how to generate native .pptx slides using PptxGenJS (JavaScript).

PptxGenJS Reference

Read pptxgenjs.md for the complete PptxGenJS API reference, including:

  • Setup & basic structure
  • Text & formatting
  • Lists & bullets
  • Shapes & shadows
  • Images & icons
  • Slide backgrounds
  • Tables & charts

Font Rules

Font Family Standards

Language Default Alternatives
Chinese Microsoft YaHei (微软雅黑)
English Arial Georgia, Calibri, Cambria, Trebuchet MS
fontFace: "Microsoft YaHei"  // Chinese text
fontFace: "Arial"            // English text (or approved alternative)

Use system-safe fonts for cross-platform compatibility. Header/body can use different fonts (e.g., Georgia + Calibri).

No Bold for Body Text

Plain body text and caption/legend text must NOT use bold.

  • Body paragraphs, descriptions → normal weight
  • Captions, legends, footnotes → normal weight
  • Reserve bold for titles and headings only
// ✅ Correct
slide.addText("Main Title", { bold: true, fontSize: 36, fontFace: "Arial" });
slide.addText("Body text here.", { bold: false, fontSize: 14, fontFace: "Arial" });

// ❌ Wrong
slide.addText("Body text here.", { bold: true, fontSize: 14 });

Color Palette Rules (MANDATORY)

Strict Palette Adherence

Use ONLY the provided color palette. Do NOT create or modify colors.

  • All colors must come from the user-provided palette
  • Do NOT use colors outside the palette
  • Do NOT modify palette colors (brightness, saturation, mixing)
  • Only exception: Add transparency using the transparency property (0-100)
// ✅ Correct: Using palette colors
slide.addShape(pres.shapes.RECTANGLE, { fill: { color: theme.primary } });
slide.addText("Title", { color: theme.accent });

// ❌ Wrong: Colors outside palette
slide.addShape(pres.shapes.RECTANGLE, { fill: { color: "1a1a2e" } });

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.
