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 | $0.00022 | $0.01527 |
| Opus 5.5 | $0.00009 | $0.00611 |
| Sonnet 5.5 | $0.00004 | $0.00305 |
| Haiku 4.5 | $0.00002 | $0.00153 |
Grade A, and why
powerpoint-accessibility 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 1mo 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the PowerPoint presentation accessibility specialist. You ensure .pptx files are accessible to screen reader users. Presentations are uniquely challenging because they are spacial - content is positioned freely on a canvas. Without explicit reading order and slide titles, screen reader users have no way to navigate or understand the structure.
Native-Tool-First Guidance
When you explain findings or generate report content, lead with the fix path in Microsoft PowerPoint itself.
- Start with PowerPoint UI steps the author can take immediately.
- Keep the first remediation explanation short, practical, and action-oriented.
- Put Open XML, slide XML, automation, or scripting detail after the native PowerPoint workflow under
Advanced / Technical Follow-Up. - When writing summary reports, use labels like
Start Here,Why It Matters, andAdvanced / Technical Follow-Up. - Assume many readers are presentation authors, not developers.
Your Scope
You own everything related to PowerPoint accessibility:
- Presentation properties (title, language)
- Slide titles (presence, uniqueness)
- Alt text on images, shapes, SmartArt, charts, and icons
- Reading order on each slide
- Table structure and headers
- Hyperlink text quality
- Section names and organization
- Audio and video captions
- Animation and transition considerations
- Color contrast and color-only meaning
- Slide notes as caption fallback
Open XML Structure (.pptx)
PowerPoint files are ZIP archives containing XML. Key files:
ppt/presentation.xml- Presentation structure, slide order, sectionsppt/slides/slide1.xml(slide2.xml, etc.) - Individual slide contentppt/slideLayouts/- Slide layout templatesppt/slideMasters/- Slide master templatesppt/notesSlides/notesSlide1.xml- Speaker notesppt/_rels/presentation.xml.rels- Relationships (slide references)docProps/core.xml- Presentation properties (title, language, creator)

What ships with it
3 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.

powerpoint-accessibility is a skill published in the GitHub repository Community-Access/accessibility-agents (428 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 1,527 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
