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.

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 | $0.00133 | $0.04537 |
| Opus 5 | $0.00067 | $0.02269 |
| Sonnet 5 | $0.00027 | $0.00907 |
| Haiku 4.5 | $0.00013 | $0.00454 |
Grade A, and why
devexpress-office-file-api-presentation 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 12d 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 — 360 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DevExpress Presentation API
The Presentation API is a cross-platform .NET library for creating, loading, modifying, saving, and printing PowerPoint presentations in code — without requiring Microsoft Office. It supports PPTX, PPTM, POTX, and POTM formats and can export to PDF. You can use it in console, desktop, and web applications targeting .NET 8+.
When to Use This Skill
Use this skill when you need to:
- Create PowerPoint presentations (.pptx) programmatically without Microsoft Office
- Load and read existing .pptx/.pptm/.potx/.potm files
- Modify existing presentations (add/remove slides, update shapes and text)
- Manage slides: add, remove, reorder, clone, or copy slides between presentations
- Work with shapes: add geometric shapes, picture shapes, and configure fill and outline
- Add and format text inside shapes (paragraphs, runs, bullets, font settings)
- Create and customize tables on slides (rows, columns, cells, styles, borders)
- Set slide backgrounds (solid color, gradient, pattern, picture)
- Configure slide masters and layouts for consistent presentation design
- Export presentations to PDF with options (security, image quality, signatures)
- Merge or split presentations
- Add, read, or remove speaker notes
- Configure headers and footers on slides
- Search, replace, or remove text across a presentation
- Extract text and images from presentation slides
- Print presentations
- Configure themes, view settings, and document properties
Prerequisites & Installation
NuGet Packages
| Package | Purpose |
|---|---|
DevExpress.Docs.Presentation |
Core presentation processing (create, load, edit, save, export) |
.NET (8/9/10+)
dotnet add package DevExpress.Docs.Presentation
Important: All DevExpress packages in a project must share the same version number. A valid DevExpress license is required.
Non-Windows Development (Linux, macOS, Docker, Cloud)
The SkiaSharp-based drawing engine is enabled automatically on non-Windows platforms. Just add the drawing engine package: dotnet add package DevExpress.Drawing.Skia.
What ships with it
6 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.
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.

devexpress-office-file-api-presentation is a skill published in the GitHub repository DevExpress/agent-skills (53 stars, last pushed 25d ago), licensed MIT. It adds 133 tokens to every session and 4,537 once invoked, about $0.0007 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.
