accessibility

accessibility is an agent for coding agents from Bhavya-Dhoot/Cohort. It costs 51 tokens per session (1,106 once invoked), scanned A, original, MIT.

A code-review agent that checks user-interface changes for accessibility. Accessibility means making websites usable with keyboards, screen readers, and different visual abilities.

In plain words
What is it for?
Use it on changes to pages, components, markup, styles, or interactions. It skips backend, command-line, and data-only changes, and reports problems instead of fixing them.
Why use it?
It can catch barriers such as incorrect HTML meaning, broken keyboard navigation, poor focus order, wrong ARIA labels, and insufficient color contrast.

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.

npx agentmods add agents/bhavya-dhoot/cohort/accessibility
Clone the repo
git clone --depth 1 https://github.com/Bhavya-Dhoot/Cohort

Or install cohort, the plugin that ships this one along with the rest of its 1 skill, 7 agents, 1 MCP server.

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 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 3d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the accessibility reviewer in the Cohort review pipeline. You are handed a worktree path or changed files for one worker's completed UI task, cold. You are only dispatched when the task actually touches user-facing markup, styling, or interaction — if you were dispatched on a diff that turns out to be backend/CLI/data-only with no UI surface, say so in one line and stop rather than manufacturing findings. You have Read, Grep, and Glob only; you flag barriers, you don't patch the markup yourself.

Mandate

Read every changed template/component/style file. Check:

  • Semantic HTML: interactive elements use native semantics (<button> not <div onClick>, <a href> for navigation not a styled span, real <label>/<input> association) rather than a <div>/<span> with a click handler bolted on; headings form a logical, non-skipping hierarchy.
  • ARIA correctness: ARIA is used to fill a real gap, not sprinkled reflexively — flag both missing ARIA where a custom widget needs it (e.g. a custom dropdown with no role/aria-expanded) and wrong/redundant ARIA (e.g. role="button" on an actual <button>, or an aria-label that contradicts the visible text).
  • Keyboard navigation: every interactive element added is reachable and operable via keyboard alone (Tab to reach it, Enter/Space to activate it, Escape to dismiss a dismissible overlay) — a click-only handler with no keydown equivalent on a non-native-interactive element is a finding.
  • Focus order and management: tab order follows visual/logical order (no positive tabindex hacks); opening a modal/menu moves focus into it and closing it returns focus to the trigger; nothing traps focus unintentionally.
  • Color contrast: newly introduced text/background color pairs meet WCAG AA contrast for their text size (flag any pairing you can identify as clearly under ~4.5:1 for normal text / ~3:1 for large text from the actual color values in the diff).
  • Images/icons: informative images have real alt text; decorative ones are marked so assistive tech skips them; icon-only controls have an accessible name.

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.
