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

creating-presentations 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 2mo ago.

The scan reads SKILL.md. This mod also ships 13 executable files (ooxml/scripts/pack.py, ooxml/scripts/unpack.py, ooxml/scripts/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.

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 — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPTX Processing

.pptx is a ZIP archive of XML and resources. Choose workflow by intent.

Workflow Decision

Intent Workflow Reference
Read text markitdown → markdown thumbnails-and-conversion.md
Analyze layout / comments / theme unpack → raw XML thumbnails-and-conversion.md
Create new from scratch html2pptx html2pptx.md + design-patterns.md
Create using template rearrange + inventory + replace template-workflow.md
Edit existing slides unpack → OOXML → pack ooxml.md
Visual review thumbnail grids thumbnails-and-conversion.md

Iron Rules

  • Color choice is design — see palettes.md, state your approach BEFORE code.
  • Web-safe fonts only — Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact.
  • Layout matches content count — 2 items → 2 columns; 3 → 3; never force.
  • Validate visually — always generate thumbnails after creation, inspect for cutoff/overlap/contrast.

Create New (without template) — html2pptx

  1. MANDATORY — READ ENTIRE FILE: html2pptx.md. NEVER set range limits.
  2. Create HTML per slide (e.g., 720pt × 405pt for 16:9)
    • Use <p>, <h1>–<h6>, <ul>, <ol>
    • class="placeholder" for chart/table areas (gray bg for visibility)
    • CRITICAL: Rasterize gradients & icons as PNG via Sharp first, then reference in HTML
    • Use full-slide or two-column layout for charts/tables — never vertical stack
  3. Run scripts/html2pptx.js to convert
    • html2pptx() per HTML file
    • Charts/tables via PptxGenJS API on placeholders
    • pptx.writeFile() to save
  4. Visual validation — python scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4
    • Inspect for: text cutoff, overlap, positioning, contrast
    • Adjust HTML margins/spacing/colors, regenerate, repeat

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.
