A set of instructions for creating, reading, and editing PowerPoint presentation files. It covers slide content, templates, charts, and the internal files used by a presentation.

Use it to extract text from presentations, inspect slide layouts, create decks, edit existing files, and add data-backed charts.

It gives an agent a defined way to work with presentations instead of treating them as ordinary text files. This helps preserve slide structure while changing content or design.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/seaworld008/Commonly-used-high-value-skills

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	$0.00040	$0.02527
Opus 5	$0.00020	$0.01264
Sonnet 5	$0.00008	$0.00505
Haiku 4.5	$0.00004	$0.00253

Security

Grade A, and why

pptx 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 3d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/__init__.py, scripts/add_slide.py, scripts/chartkit.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.

Editing Workflow

Read editing.md for full details.

Analyze template with thumbnail.py
Unpack → manipulate slides → edit content → clean → pack

Creating from Scratch

Read pptxgenjs.md for full details.

Use when no template or reference presentation is available.

For a multi-section executive, sales, or analytical deck, load only the relevant files under references/creator-workflow/:

INTAKE.md and WORKFLOW.md for scope and sequencing
STYLE-GUIDE.md and VIS-GUIDE.md for visual direction
ORCHESTRATION_DATA_CHARTS.md when the deck depends on data-backed charts
RUBRIC.md and CHECKLIST.md for final acceptance

Use scripts/chartkit.py for a deterministic PNG fallback from CSV or JSON when native chart generation is unavailable. The rendered chart still requires visual inspection for labels, scale, and contrast.

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.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
