A skill for working with PowerPoint presentation files in the .pptx format, including reading, creating, and editing slide decks.

Use it to analyze presentations, create decks, edit existing slides, generate thumbnails, and inspect the underlying slide files.

It provides a defined process for extracting slide content, inspecting layouts, and changing presentations while preserving their structure.

About the project

OpenGauss is a project-scoped Lean workflow orchestrator that gives coding agents a command-line interface for managing formal proof and formalization tasks. It is used with Lean projects to coordinate agents, tooling, backend sessions, and workflows supplied by lean4-skills. The catalogue add-ons operate these Gauss-native workflows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00152	$0.02367
Opus 5	$0.00076	$0.01184
Sonnet 5	$0.00030	$0.00473
Haiku 4.5	$0.00015	$0.00237

Security

Grade A, and why

powerpoint 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.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/__init__.py, scripts/add_slide.py, scripts/clean.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.

Design Ideas

Don't create boring slides. Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.

Before Starting

Pick a bold, content-informed color palette: The palette should feel designed for THIS topic. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices.
Dominance over equality: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight.
Dark/light contrast: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel.
Commit to a visual motif: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles, thick single-side borders. Carry it across every slide.

Color Palettes

Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:

Theme	Primary	Secondary	Accent
Midnight Executive	`1E2761` (navy)	`CADCFC` (ice blue)	`FFFFFF` (white)
Forest & Moss	`2C5F2D` (forest)	`97BC62` (moss)	`F5F5F5` (cream)
Coral Energy	`F96167` (coral)	`F9E795` (gold)	`2F3C7E` (navy)
Warm Terracotta	`B85042` (terracotta)	`E7E8D1` (sand)	`A7BEAE` (sage)
Ocean Gradient	`065A82` (deep blue)	`1C7293` (teal)	`21295C` (midnight)
Charcoal Minimal	`36454F` (charcoal)	`F2F2F2` (off-white)	`212121` (black)
Teal Trust	`028090` (teal)	`00A896` (seafoam)	`02C39A` (mint)

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.
