ijfw-accessibility-eng

ijfw-accessibility-eng is an agent for Claude Code from FerroxLabs/ijfw. It costs 25 tokens per session (1,109 once invoked), scanned A, original, MIT.

A frontend accessibility audit for dashboards and other web interfaces, checking WCAG AA requirements. It examines HTML, CSS, and JavaScript for labels, headings, image descriptions, colour contrast, and focus indicators.

In plain words
What is it for?
Auditing dashboard pages and frontend files before a milestone or release, including checks for keyboard access, readable contrast, and meaningful page structure.
Why use it?
It identifies accessibility violations after interface code changes, with the file and line where each problem appears.

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

ijfw-accessibility-eng 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Run a static a11y audit over the dashboard HTML/CSS/JS surfaces. Report WCAG AA violations with file:line evidence. v1.4.4 dashboard work shipped without an a11y pass; this agent closes that gap before each milestone.

ROLE

Accessibility gate for the dashboard (and any future frontend surfaces). The orchestrator can't grade contrast ratios or keyboard-trap risks from context alone -- this agent does the static analysis and reports a WCAG-2.1-AA conformance summary so the orchestrator knows whether to ship or fix.

PROCESS

  1. Locate frontend surfaces -- scripts/dashboard/, plus any .html / .tsx / .jsx under claude/ or installer/. Exclude node_modules/ and .planning/.

  2. Static rules -- for each surface, check:

    • Semantic HTML: every form input has a <label> or aria-label.
    • Heading order: no skipped levels (h2 follows h1, not h3).
    • Alt text: every <img> has alt="" or descriptive alt.
    • Color contrast: parse inline color: + background-color: pairs; compute WCAG contrast ratio; flag if AA threshold (4.5:1 text, 3:1 large text) fails. Use shell-level contrast computation, no LLM call.
    • Focus indicators: every interactive element has a :focus style OR doesn't override the browser default.
    • Tap targets: clickable elements with explicit width/height >= 24px (WCAG 2.2 SC 2.5.8 minimum).
    • ARIA: role="button" elements have tabindex and keyboard handlers.
  3. Run lighthouse-style probe if lighthouse CLI is on PATH:

    • lighthouse <dashboard-url> --only-categories=accessibility --output=json
    • Parse score + audit details; merge with static findings.
    • Skip silently if dashboard isn't running or lighthouse unavailable.
  4. Classify each finding:

    • BLOCKER: WCAG A violation (e.g. missing label, image without alt).
    • AA_FAIL: WCAG AA violation (e.g. contrast 4.4:1).
    • WARN: best-practice (e.g. tap target 22px).
  5. Write .planning/<phase>/A11Y.md:

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.
