pptx-builder

A workflow for creating editable PowerPoint presentation files. It builds slides from native text, shapes, tables, charts, connectors, and supporting images instead of making each slide one flat picture.

In plain words
What is it for?
Use it to turn a narrative and design specification into production-ready PPTX decks. It supports business slides, metrics, tables, diagrams, charts, and other presentation content.
Why use it?
It keeps the important slide content editable, so users can change text, numbers, diagrams, and layouts in PowerPoint.

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.

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-builder 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.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PPTX Builder

Create editable PowerPoint decks. Use native text, shapes, lines, tables, connectors, and images. Keep the JSON layout tree as the source of truth and use a small, task-specific python-pptx builder only when a PPTX file is required.

Non-Negotiable Output Rules

  • Build editable slides. Do not use a full-slide image as the slide's content.
  • Use native PowerPoint objects for titles, body text, metrics, tables, diagrams, charts, and other information the user may need to edit.
  • Use images only as supporting visuals, such as photographs, logos, textures, or illustrations. An image must not be the only meaningful object on a slide.
  • Do not put essential text, data labels, or the only explanation of a diagram inside an image. Recreate that information with native objects.
  • Write clear U.S. business English. Use short sentences, common words, direct verbs, and specific claims. Check grammar, spelling, numbers, and titles. Avoid idioms, filler, and placeholder text.
  • Keep the implementation small. Do not add a general renderer, a large helper library, or a code-heavy framework.
  • pptx-deck-context: narrative, source material, and design context
  • pptx-slide-specification: final coordinates and the spec-to-PPTX contract
  • pptx-visual-assets: permitted asset selection and placement
  • pptx-reference-deck-analysis: read-only reference-deck analysis, safe OOXML inspection, and package validation
  • pptx-quality-gates: build, package, geometry, and accessibility checks

Read the relevant skill before using its rules. If a required reference file is missing, state the path and use only information the user supplied. Do not invent missing brand, source, or accessibility details.

Workflow

Understand the request

  1. Collect the audience, decision or purpose, slide count, language, source material, brand requirements, and delivery date.
  2. Ask no more than five focused questions at once. Offer practical defaults for slide count, language, and reference deck when the user has not given them.
  3. Ask the user to select a narrative framework when one is not supplied. Do not select one without the user's approval.
  4. If a topic alone cannot support a credible deck, ask one direct question for the missing decision, audience, or source facts. Do not add placeholder text.

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.
