pptx

A tool-first skill for working with PowerPoint .pptx files, including creating presentations, reading content, extracting notes, and editing slide files.

In plain words
What is it for?
Use it to create slide decks, extract text or speaker notes, inspect slides, unpack files for editing, and repack edited presentations.
Why use it?
It provides a defined way to inspect and modify presentations without treating them as ordinary text files.

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

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 2d 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.

Tool-First Workflow

Use the Presentation tool for ALL operations. Do NOT use Python scripts unless you need features the tool doesn't have.

Available Presentation tool actions

Task Tool call
Inspect metadata Presentation { action: "inspect", file_path: "deck.pptx" }
List all slides Presentation { action: "list_slides", file_path: "deck.pptx" }
Extract text (all or one slide) Presentation { action: "extract_text", file_path: "deck.pptx" }
Read speaker notes Presentation { action: "read_notes", file_path: "deck.pptx" }
Export text outline Presentation { action: "export_text_outline", file_path: "deck.pptx" }
Create new presentation Presentation { action: "create", output_path: "deck.pptx", content: {slides: [{title, body: [...]}]} }
Unpack for XML editing Presentation { action: "unpack", file_path: "deck.pptx", output_path: "unpacked/" }
Repack after editing Presentation { action: "pack", file_path: "unpacked/", output_path: "output.pptx" }

Editing an existing presentation

Presentation { action: "unpack", file_path: "template.pptx", output_path: "/tmp/unpacked/" }
# → Edit slide XML files in /tmp/unpacked/ppt/slides/ with the Edit tool
# → Reorder slides by editing /tmp/unpacked/ppt/presentation.xml
Presentation { action: "pack", file_path: "/tmp/unpacked/", output_path: "output.pptx" }

Creating from scratch

Presentation { action: "create", output_path: "deck.pptx", content: {
  "layout": "16x9",
  "slides": [
    {"title": "Welcome", "body": ["Point 1", "Point 2", "Point 3"]},
    {"title": "Details", "body": ["Item A", "Item B"], "notes": "Speaker notes here"}
  ]
}}

For advanced presentations (charts, images, custom layouts), use PptxGenJS via Bash — see pptxgenjs.md.

When to fall back to Python

  • Thumbnail grids (requires LibreOffice + PIL)
  • Converting PPTX to PDF (requires LibreOffice)

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.

pptx is a skill published in the GitHub repository SeifBenayed/cloclo (114 stars, last pushed 4mo ago), licensed MIT. It adds 152 tokens to every session and 3,029 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
