At a glance

Scan and fix .pptx files: slide titles, alt text and reading order.

  • Works in 2 steps: [ ] Presentation has a title in… → [ ] Presentation language is set…
  • Tasks that involve PowerPoint presentations
  • SKILL.md covers Native-Tool-First Guidance, Your Scope, Open XML Structure (.pptx) and Validation Checklist, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Powerpoint Accessibility is an agent skill from Community-Access/accessibility-agents. Scan and fix .pptx files: slide titles, alt text and reading order.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/complete-rule-set.md` and `references/structured-output-for-sub-agent-use.md`).

It sits in Documents & Office, covering PowerPoint presentations, Slides and decks and Accessibility. It works with Microsoft PowerPoint. The repository describes itself as: Accessibility review agents for Claude Code, GitHub Copilot, and Claude Desktop. Eleven specialists that enforce WCAG 2.2 AA compliance so AI coding tools stop generating… The licence is MIT.

When your agent uses it

  • Tasks that involve PowerPoint presentations
  • Tasks that involve Slides and decks
  • Tasks that involve Accessibility

Example prompts

  • “/powerpoint-accessibility”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. [ ] Presentation has a title in properties (PPTX-W001)
  2. [ ] Presentation language is set (PPTX-T004)

What it can do on your machine

Read from SKILL.md and the folder at commit decf6ba. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Powerpoint Accessibility loads about 1.6k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 23 tokens; SKILL.md has 766 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

PowerPoint Accessibility

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, and Advanced / 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, sections
  • ppt/slides/slide1.xml (slide2.xml, etc.) - Individual slide content
  • ppt/slideLayouts/ - Slide layout templates
  • ppt/slideMasters/ - Slide master templates
  • ppt/notesSlides/notesSlide1.xml - Speaker notes
  • ppt/_rels/presentation.xml.rels - Relationships (slide references)
  • docProps/core.xml - Presentation properties (title, language, creator)

Validation Checklist

Presentation Properties
  1. Presentation has a title in properties (PPTX-W001)
  2. Presentation language is set (PPTX-T004)
Slide Structure
  1. Every slide has a title (PPTX-E002)
  2. No duplicate slide titles (PPTX-E003)

  5. Alt text is concise (under 150 chars) (PPTX-W006)
  6. Audio/video has captions or transcript (PPTX-W004)
Tables
  1. All tables have header rows (PPTX-E004)
  2. No merged cells in tables (PPTX-W003)
  3. Tables are for data, not layout (PPTX-W002)
  1. All hyperlinks have descriptive text (PPTX-E005)
Color and Animation
  1. Color is not the only way to convey meaning (PPTX-W005)
  2. Animations and transitions are not excessive (PPTX-T002)
Notes
  1. Slides have speaker notes for context (PPTX-T003)

Configuration

Rule sets can be customized per file type using .a11y-office-config.json. See the office-scan-config agent for details.

Example - only check errors and warnings, skip tips:

json
{
  "pptx": {
    "enabled": true,
    "disabledRules": [],
    "severityFilter": ["error", "warning"]
  }
}

Common Mistakes You Must Catch

  • Slides with no title placeholder at all - every slide must have a title, even if it's visually hidden
  • Title placeholder exists but is empty - an empty title is the same as no title for screen readers
  • Alt text that says "image" or "Picture 3" - describe the content, not the object type
  • Reading order never checked - objects are read in insertion order, not visual position
  • Embedded YouTube videos without captions - verify captions are enabled on the video source
  • Complex SmartArt without alt text - SmartArt can contain many shapes; the group needs a single descriptive alt text
  • Tables used to align text in columns - use text boxes or columns instead
  • Animations that auto-advance - screen reader users may not have time to read the content

Multi-Agent Reliability

Role

You are a read-only scanner. You analyze PowerPoint documents and produce structured findings. You do NOT modify documents.

Output Contract

Every finding MUST include these fields:

  • rule_id: PPTX-prefixed rule ID
  • severity: critical | serious | moderate | minor
  • location: file path, slide number, element description
  • description: what is wrong
  • remediation: how to fix it
  • wcag_criterion: mapped WCAG 2.2 success criterion
  • confidence: high | medium | low

Findings missing required fields will be rejected by the orchestrator.

Handoff Transparency

When you are invoked by document-accessibility-wizard:

  • Announce start: "Scanning [filename] for PowerPoint accessibility issues ([N] rules active)"
  • Announce completion: "PowerPoint scan complete: [N] issues found ([critical]/[serious]/[moderate]/[minor])"
  • On failure: "PowerPoint scan failed for [filename]: [reason]. Returning partial results for [N] files that succeeded."

When handing off to another agent:

  • State what you found and what the next agent will do with it
  • Example: "Found [N] issues in [filename]. Handing off to cross-document-analyzer for pattern detection across all scanned documents."

Reference files

Read one only when the task reaches it. Do not read them all up front.

  • references/complete-rule-set.md - Complete Rule Set, Rule Details and Remediation
  • references/structured-output-for-sub-agent-use.md - Structured Output for Sub-Agent Use

Output contract

Return only JSON matching skills/a11y-core/schemas/findings.schema.json. No prose, no summary, no restated instructions. One object, one array of findings.

Shared rules, dispatch contract and schemas: skills/a11y-core/SKILL.md. Authoritative specifications for this skill: skills/a11y-core/references/sources.md.
