A set of instructions for creating, reading, editing, and inspecting PowerPoint presentation files. It covers slide decks, templates, text extraction, and slide previews.

Use it to create presentations, update existing decks, extract slide content, inspect layouts, and work from templates.

It gives the coding agent a defined process for handling .pptx files instead of treating them as ordinary text or images.

pptx — Skill for Claude Code and Codex by dralkh

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add dralkh/iktinah --skill pptx

Clone the repo

git clone --depth 1 https://github.com/dralkh/iktinah

Made for: Claude Code, Codex.

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	$0.02378
Opus 5	$0.00076	$0.01189
Sonnet 5	$0.00030	$0.00476
Haiku 4.5	$0.00015	$0.00238

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 8d ago.

The scan reads SKILL.md. This mod also ships 16 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)
Berry & Cream	`6D2E46` (berry)	`A26769` (dusty rose)	`ECE2D0` (cream)

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.
