An accessibility testing workflow for checking a web page against WCAG, the commonly used rules for making websites usable by people with disabilities. It uses axe, an accessibility testing service, and can apply and recheck fixes.

Use it to audit a page URL, review WCAG 2.2 AA issues, apply fixes when requested, and verify the result.

It finds accessibility violations and connects them to guidance for correcting them, instead of relying only on manual inspection.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add easingthemes/dx-aem-flow

Claude Code

/plugin install dx-core

Made for: Claude Code.

Or install dx-core, the plugin that ships this one along with the rest of its 49 skills, 7 agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.02167
Opus 5	$0.00024	$0.01084
Sonnet 5	$0.00010	$0.00433
Haiku 4.5	$0.00005	$0.00217

Security

Grade A, and why

dx-axe 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 6d 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 — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You perform accessibility testing and remediation using the Deque axe MCP Server. You follow a strict analyze → remediate → fix → verify workflow.

1. Parse Arguments

Extract from $ARGUMENTS:

URL (required) — the page URL to test
--fix flag — if present, automatically apply remediation fixes to source code after analysis
--standard — WCAG standard to test against (default: wcag2aa)

If no URL is provided, ask the user for one.

2. Load axe MCP Tools

Use ToolSearch to discover the axe MCP Server tools:

ToolSearch query: "+axe analyze"

Look for tools matching axe_mcp_server__analyze and axe_mcp_server__remediate (or similar naming with axe prefix).

If not found, tell the user:

axe MCP Server not available. See setup guide: docs/dx-axe.md in the plugin repo. Quick checklist: Docker running? AXE_API_KEY exported? Image pulled (docker pull dequesystems/axe-mcp-server:latest)? Plugin reinstalled after setup?

Then STOP.

3. Resolve URL for axe

The axe MCP Server runs inside Docker. URLs must be reachable from the container.

Local AEM (`localhost`)

Replace localhost with host.docker.internal in the URL passed to axe — inside Docker, localhost is the container itself:

User provides	Pass to axe
`http://localhost:4502/...`	`http://host.docker.internal:4502/...`
`http://admin:admin@localhost:4502/...`	`http://admin:[email protected]:4502/...`

If the URL has no credentials and the host is localhost:4502, embed admin:admin (AEM default local credentials):

http://admin:[email protected]:4502/content/...?wcmmode=disabled

Remote AEM (QA / Stage)

Follow the qa-basic-auth rule. Resolve credentials in priority order:

Env vars: QA_BASIC_AUTH_USER / QA_BASIC_AUTH_PASS
.ai/config.yaml keys aem.qa-basic-auth.username / aem.qa-basic-auth.password

If credentials are found, embed them in the URL for the first navigation only — the session cookie persists for subsequent navigations:

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.

dx-axe is a skill published in the GitHub repository easingthemes/dx-aem-flow (6 stars, last pushed 4d ago), licensed MIT. It adds 48 tokens to every session and 2,167 once invoked, about $0.0002 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 2026-08-31.
