accessibility-audit

accessibility-audit is a skill for Claude Code, Codex from androoAGI/starnet. It costs 31 tokens per session (549 once invoked), scanned A, original, MIT.

A live-page accessibility audit focused on barriers that prevent people from using a site. It checks keyboard access, visible focus, control names, colour contrast, headings, labels, and image descriptions.

In plain words
What is it for?
It helps verify keyboard navigation, focus behaviour, accessible names, readable colours, page structure, form labels, and meaningful image text.
Why use it?
It finds usability blockers that automated warning lists can miss or fail to prioritise.

About the project

StarNet is a local-first desktop harness for creating AI agents and arranging them in a pixel-art space station whose layout represents their capabilities, permissions, and workflow. It lets people run real model calls and tools through multiple bounded agents, using their own provider keys or accounts and optionally messaging the station through chat services. The catalogue entries are skills that extend or support work performed by StarNet 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.

Security

Grade A, and why

accessibility-audit 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 — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Accessibility work goes wrong when it becomes a list of automated warnings nobody acts on. The useful version checks the small number of failures that genuinely prevent someone from using the page, and proves each one on the live page.

Method

  1. Walk the page with the keyboard only. Tab through every interactive element in order. Anything reachable by mouse but not by keyboard is a hard blocker, as is a focus trap you cannot escape, or a tab order that jumps around the page.
  2. Check that focus is VISIBLE. A removed focus outline with nothing in its place makes keyboard use impossible even when the tab order is correct.
  3. Check names on controls. Every button, link, input, and icon-only control needs an accessible name. Read the page's structure and find controls whose name is empty, or is "button", or is a filename.
  4. Check contrast on real rendered colours — body text, muted/secondary text, placeholder text, text on images, and disabled states, which are the ones that usually fail.
  5. Check structure: one main heading, headings that descend without skipping, form inputs tied to labels, images with alt text that says what the image MEANS (and empty alt for decoration).
  6. Check motion and state: anything that animates or auto-plays, and whether errors are announced rather than only shown in red.
  7. Rank by who is locked out. A keyboard trap outranks a heading-order warning by a wide margin.

Rules

  • Test the live rendered page, not the source — computed colours and injected markup are what users actually meet.
  • Every finding names the element and gives the concrete fix, not a WCAG number on its own.
  • Never claim compliance. Automated and manual checks find barriers; they do not certify a standard. Say what was checked and what was not.
  • Real assistive-technology testing by a human is the finish line — say so when the stakes warrant it.

Output

Blockers first (keyboard, focus, unnamed controls), then serious issues, then polish — each with the element, what it breaks for whom, and the fix. Plus what you could not check.

Changes

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.
