What it does

Accessibility Testing Strategy is an agent skill from Owl-Listener/inclusive-design-skills. Plan what to test, how to test, and who should test for accessibility. Use when defining a testing approach, planning QA, setting up automated and manual testing, or deciding what level of accessibility testing a project needs. Triggers on: accessibility testing, how to test, test plan, automated testing, manual testing, screen reader testing, user testing, accessibility QA, what to test, testing strategy.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Accessibility. The repository describes itself as: Inclusive design skills for AI coding agents — from cognitive accessibility to adaptive interfaces, inclusive research, and accessibility decision-making. The licence is MIT.

When your agent uses it

  • Defining a testing approach
  • Setting up automated and manual testing
  • Deciding what level of accessibility testing a project needs
  • : accessibility testing

Example prompts

  • “/accessibility-testing-strategy”

Workflow steps

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

  1. Is automated testing running on every build?
  2. Is manual expert testing happening before each release?
  3. Has the product been tested by people with disabilities?
  4. Are core tasks tested with keyboard and screen reader?
  5. Is there a clear priority for what to test first?

What it can do on your machine

Read from SKILL.md and the folder at commit 6e0740f. 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.

    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

Accessibility Testing Strategy loads about 1k tokens when it runs. Until then it costs about 110 tokens; SKILL.md has 505 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

Accessibility Testing Strategy

Plan a testing approach that catches real accessibility barriers — because automated tools find roughly 30% of issues. The other 70% require human judgment.

The Testing Pyramid

Layer 1: Automated Testing (Catches ~30%)

What it finds:

  • Missing alt text
  • Colour contrast failures
  • Missing form labels
  • Missing language attribute
  • Empty headings and buttons
  • Duplicate IDs

What it misses:

  • Whether alt text is meaningful
  • Whether focus order is logical
  • Whether content makes sense
  • Whether interactions work with keyboard
  • Whether the experience is usable

Tools: axe, Lighthouse, WAVE, Pa11y, jest-axe When: on every build, in CI/CD pipeline Who: automated — no human needed

Layer 2: Manual Expert Testing (Catches ~50%)

What it finds:

  • Keyboard navigation issues
  • Focus management problems
  • Logical reading order failures
  • Meaningful alt text assessment
  • Cognitive accessibility barriers
  • Interaction pattern issues

Method:

  • Tab through every interactive element
  • Test with screen reader (VoiceOver or NVDA)
  • Test at 200% zoom
  • Test with system preferences enabled
  • Review content for plain language

When: before each release, on major feature changes Who: someone trained in accessibility testing

Layer 3: User Testing With Disabled People (Catches remaining ~20%)

What it finds:

  • Real-world usability barriers that experts miss
  • Assistive technology compatibility issues
  • Unexpected workflows and workarounds
  • Cognitive and emotional barriers
  • Issues that only appear with actual AT proficiency

Method:

  • Recruit participants with diverse disabilities
  • Test core tasks with their own devices and AT
  • Observe — don't guide or explain
  • Record what works, what fails, and what frustrates

When: quarterly, or before major launches Who: users with disabilities using their own setup

What to Test First

Priority 1: Core Tasks
  • Can users complete the primary tasks the product exists for?
  • Test the critical path end to end
  • Any failure here is a launch blocker
Priority 2: Input and Navigation
  • Keyboard-only navigation through the core flow
  • Screen reader navigation through the core flow
  • Touch interaction on mobile for the core flow
Show full SKILL.md (194 more words)Show less
Priority 3: Content and Comprehension
  • Is content understandable at the target reading level?
  • Are error messages helpful?
  • Is help available and findable?
Priority 4: Edge Cases and Preferences
  • Zoom to 200%
  • System preferences (reduced motion, high contrast, dark mode)
  • Long content, empty states, error states

Screen Reader Testing Basics

For teams new to screen reader testing:

Start With VoiceOver (Mac)
  • Turn on: Cmd + F5
  • Navigate: VO + arrow keys (VO = Ctrl + Option)
  • Headings: VO + Cmd + H
  • Links: VO + Cmd + L
  • Forms: VO + Cmd + J
  • Turn off: Cmd + F5
Start With NVDA (Windows)
  • Download free from nvaccess.org
  • Navigate: Tab, arrow keys
  • Headings: H
  • Links: K
  • Forms: F
  • Stop speech: Ctrl
What to Listen For
  • Does every interactive element have a name?
  • Are state changes announced (expanded, selected, checked)?
  • Does focus move to the right place after actions?
  • Can you understand the page reading only the headings?

Assessment Questions

  1. Is automated testing running on every build?
  2. Is manual expert testing happening before each release?
  3. Has the product been tested by people with disabilities?
  4. Are core tasks tested with keyboard and screen reader?
  5. Is there a clear priority for what to test first?
