feat: WCAG 2.2 AA accessibility detection with wcag_audit tool
Adds accessibility intelligence to GitNexus — detects WCAG 2.2 AA violations in JSX/TSX components, maps findings to success criteria, and provides compliance scoring via the wcag_audit MCP tool. Phase 1 implementation: - JSX element extraction from TSX/JSX files (regex-based, correlates elements with attributes, classNames, text content) - A11ySignal node type with HAS_A11Y_SIGNAL edges in knowledge graph - 12 WCAG rules across 4 principles: - Perceivable: img-alt, icon-button-label, input-label, landmarks - Operable: keyboard, no-keyboard-trap, bypass-blocks, page-titled - Understandable: language-page - Robust: name-role-value, status-messages - Deaf-specific: video-captions - wcag_audit MCP tool with compliance score, violation list, fix patterns from the codebase, and EU compliance context tags - Pipeline phase 3.8 integration Each finding includes compliance context: - EU: Required by EN 301 549 (mandatory for EU compliance) - EU: Recommended - WCAG AAA (exceeds EU minimum) - Deaf-specific (important for deaf/HoH users) All findings are informational — shown always, never blocking. The WCAG rule set and detection patterns are informed by production accessibility tooling built and validated on real EU-funded projects with EN 301 549 compliance requirements.

# WCAG Accessibility Detection for GitNexus
|
||||
|
||||
**Date:** 2026-03-26
|
||||
**Status:** Approved
|
||||
**Approach:** Hybrid — Tree-sitter JSX extraction + structured WCAG rule engine
|
||||
**Target:** WCAG 2.2 AA (EN 301 549 compatible)
|
||||
|
||||
## Problem
|
||||
|
||||
GitNexus analyzes code structure, call graphs, and data flow, but has no awareness of accessibility. When an AI agent is asked to fix a11y issues, it must read dozens of files to understand the component tree, guess at patterns, and has no way to know which WCAG criteria are met or violated. This wastes tokens and produces unreliable fixes.
|
||||
|
||||
Meanwhile, EU-funded projects (like those in this workspace) must comply with EN 301 549 which references WCAG 2.1 AA, with WCAG 2.2 AA expected as the upcoming standard.
|
||||
|
||||
## Goals
|
||||
|
||||
1. **Index a11y signals** during pipeline analysis — extract JSX elements, attributes, ARIA patterns, store in graph
|
||||
2. **Map to WCAG 2.2 AA criteria** — 42 detectable rules covering perceivable, operable, understandable, robust principles
|
||||
3. **Provide AI agent context** — structured findings with fix patterns from the same codebase, reducing token usage by ~90%
|
||||
4. **Per-route compliance reporting** — compliance score, violation list, per-route matrix via `wcag_audit` MCP tool
|
||||
5. **A11y regression detection** — integrate with `detect_changes` and `impact` tools
|
||||
6. **Informational, not blocking** — all findings always shown, teams decide what to act on
|
||||
|
||||
## Non-Goals
|
||||
|
||||
- Runtime testing (color contrast rendering, screen reader behavior, focus order testing)
|
||||
- CSS file parsing (Tailwind classes in JSX are in scope; standalone .css files are not)
|
||||
- Third-party component internals (trust Radix, MUI, etc. are accessible)
|
||||
- Build/CI blocking or enforcement
|
||||
|
||||
## Graph Model
|
||||
|
||||
### New Node: `A11ySignal`
|
||||
|
||||
Represents a detected accessibility signal on a specific element in a component.
|
||||
|
||||
| Property | Type | Description |
|
||||
|----------|------|-------------|
|
||||
| `name` | string | Human-readable (e.g., `"img missing alt"`, `"button has aria-label"`) |
|
||||
| `criterion` | string | WCAG SC number (e.g., `"1.1.1"`, `"2.1.1"`) |
|
||||
| `status` | enum | `violation` \| `warning` \| `pass` |
|
||||
| `severity` | enum | `critical` \| `serious` \| `moderate` \| `minor` |
|
||||
| `element` | string | JSX element tag (e.g., `"img"`, `"button"`, `"div"`) |
|
||||
| `filePath` | string | Source file |
|
||||
| `startLine` | number | Line of the element |
|
||||
| `confidence` | enum | `definite` \| `likely` \| `heuristic` |
|
||||
| `complianceTag` | enum | `eu-required` \| `eu-recommended` \| `wcag-aaa` \| `deaf-specific` |
|
||||
|
||||
### New Edge: `HAS_A11Y_SIGNAL` (Function/File → A11ySignal)
|
||||
|
||||
Connects a component to its a11y signals.
|
||||
|
||||
| Property | Type | Description |
|
||||
|----------|------|-------------|
|
||||
| `confidence` | number | 0-1 |
|
||||
| `reason` | string | Detection method (e.g., `"tree-sitter\|missing-alt"`) |
|
||||
|
||||
### Query Path
|
||||
|
||||
```
|
||||
Route → HANDLES_ROUTE → File → CONTAINS → Function (component)
|
||||
↓
|
||||
HAS_A11Y_SIGNAL
|
||||
↓
|
||||
A11ySignal
|
||||
```
|
||||
|
||||
Per-page compliance = follow the route chain, collect all A11ySignals, group by criterion.
|
||||
|
||||
## JSX Extraction Layer
|
||||
|
||||
### ExtractedJSXElement interface
|
||||
|
||||
```typescript
|
||||
interface ExtractedJSXElement {
|
||||
tag: string; // "img", "button", "div", "input", "a", "video"
|
||||
filePath: string;
|
||||
lineNumber: number;
|
||||
attributes: Map<string, string | true>; // { alt: "photo", onClick: true, role: "button" }
|
||||
hasChildren: boolean; // <button>Click me</button> vs <button />
|
||||
textContent?: string; // Direct text children
|
||||
enclosingFunction: string; // Which component this element lives in
|
||||
parentTag?: string; // Immediate parent element
|
||||
classNames?: string[]; // Parsed from className="..."
|
||||
inlineStyles?: Map<string, string>; // Parsed from style={{...}}
|
||||
}
|
||||
```
|
||||
|
||||
### Tree-sitter queries
|
||||
|
||||
New queries added to `TYPESCRIPT_QUERIES` and `JAVASCRIPT_QUERIES` for TSX/JSX grammars:
|
||||
|
||||
- `jsx_self_closing_element` with tag name and attributes
|
||||
- `jsx_opening_element` with tag name and attributes
|
||||
- `jsx_attribute` with name and value (string, expression, or absent)
|
||||
- `jsx_text` for text content children
|
||||
|
||||
### Pipeline integration
|
||||
|
||||
Extracted during existing Phase 3 (parse worker), accumulated alongside `allFetchCalls` and `allStateSlots`. Only for `.tsx`, `.jsx` files.
|
||||
|
||||
### What's NOT extracted
|
||||
|
||||
- Standalone CSS files (Tailwind classes in JSX classNames ARE extracted)
|
||||
- Runtime-computed attribute values (`aria-label={condition ? "a" : "b"}` — we detect the attribute exists, can't resolve the value, confidence: `heuristic`)
|
||||
- Third-party component internals
|
||||
|
||||
## WCAG Rule Engine
|
||||
|
||||
### Rule interface
|
||||
|
||||
```typescript
|
||||
type WCAGRule = {
|
||||
id: string; // "img-alt"
|
||||
criterion: string; // "1.1.1"
|
||||
name: string; // "Non-text Content"
|
||||
severity: 'critical' | 'serious' | 'moderate' | 'minor';
|
||||
complianceTag: 'eu-required' | 'eu-recommended' | 'wcag-aaa' | 'deaf-specific';
|
||||
check: (elements: ExtractedJSXElement[], filePath: string) => A11ySignal[];
|
||||
};
|
||||
```

|
||||
|
||||
### Input
|
||||
|
||||
| Param | Type | Description |
|
||||
|-------|------|-------------|
|
||||
| `route` | string? | Filter by route |
|
||||
| `criterion` | string? | Filter by WCAG SC number |
|
||||
| `status` | string? | `"violation"` \| `"warning"` — default: show all |
|
||||
| `component` | string? | Filter by component name |
|
||||
| `repo` | string? | Repository slug |
|
||||
|
||||
### Output
|
||||
|
||||
Three views in one response:
|
||||
|
||||
**1. Compliance score**
|
||||
```
|
||||
WCAG 2.2 AA: 83% (35/42 criteria met)
|
||||
Perceivable: 9/12 — Operable: 11/12 — Understandable: 8/10 — Robust: 7/8
|
||||
```
|
||||
|
||||
**2. Violation list with fix patterns**
|
||||
```
|
||||
Findings (14):
|
||||
SC 1.1.1 (Non-text Content) — 2 findings [EU: Required by EN 301 549]
|
||||
FileUpload.tsx:42 — img button without aria-label
|
||||
Fix pattern: src/components/ui/button.tsx:89
|
||||
GrantCard.tsx:15 — img with empty alt=""
|
||||
Fix pattern: src/features/grants/components/GrantHeader.tsx:8
|
||||
|
||||
SC 2.1.1 (Keyboard) — 1 finding [EU: Required by EN 301 549]
|
||||
KanbanCard.tsx:18 — div with onClick, no keyboard handler
|
||||
Fix pattern: src/features/tasks/components/TaskCard.tsx:24
|
||||
```
|
||||
|
||||
**3. Per-route compliance matrix**
|
||||
```
|
||||
Route /grants/[slug]:
|
||||
Components: GrantForm, BudgetTable, FileUpload, StatusBadge
|
||||
SC 1.1.1: 1 finding (FileUpload)
|
||||
SC 1.3.1: 1 finding (BudgetTable missing caption)
|
||||
SC 2.1.1: clean
|
||||
SC 3.1.2: 2 findings (hardcoded strings)
|
||||
```
|
||||
|
||||
### Compliance tags on every finding
|
||||
|
||||
| Tag | Meaning |
|
||||
|-----|---------|
|
||||
| `EU: Required by EN 301 549` | Part of WCAG 2.2 AA — mandatory for EU compliance |
|
||||
| `EU: Recommended` | Best practice referenced in European Accessibility Act guidance |
|
||||
| `WCAG AAA` | Beyond AA — exceeds EU minimum |
|
||||
| `Deaf-specific` | Important for deaf/HoH users |
|
||||
|
||||
All findings always shown. Tags provide context. Teams decide what to act on.
|
||||
|
||||
### Fix patterns
|
||||
|
||||
For each violation, search the same codebase for components that pass the same criterion. Return the closest match as a fix pattern. Priority: same directory > same feature > anywhere in project.
|
||||
|
||||
### Integration with existing tools
|
||||
|
||||
| Tool | Change |
|
||||
|------|--------|
|
||||
| `detect_changes` | After mapping diff to symbols, report affected WCAG criteria |
|
||||
| `impact` | When BFS reaches a component with A11ySignals, include them |
|
||||
| `context` | Show a11y signals in 360-degree view |
|
||||
|
||||
## Implementation Phases
|
||||
|
||||
### Phase 1: Foundation — JSX extraction + core rules + wcag_audit tool
|
||||
- Add JSX tree-sitter queries to TS/JS query strings
|
||||
- ExtractedJSXElement extraction in parse worker
|
||||
- A11ySignal node type in graph, LadybugDB schema, CSV generator
|
||||
- 10 core rules: img-alt, icon-button-label, input-label, keyboard, no-keyboard-trap, bypass-blocks, language-page, name-role-value, status-messages, video-captions
|
||||
- Basic `wcag_audit` MCP tool with compliance score + violation list
|
||||
- Seed-based tests + pipeline-level tests
|
||||
|
||||
### Phase 2: Full WCAG 2.2 AA rule coverage
|
||||
- Remaining 32 rules across all 4 principles
|
||||
- Tailwind resolver for CSS-related rules
|
||||
- Per-route compliance matrix in wcag_audit output
|
||||
- Fix pattern search
|
||||
- Compliance tags (EU/WCAG AAA/deaf-specific)
|
||||
- Real-repo validation on fluentiagrant-app
|
||||
|
||||
### Phase 3: Tool integration + graph-enhanced rules
|
||||
- Extend detect_changes with a11y regression detection
|
||||
- Extend impact and context tools
|
||||
- Graph-enhanced rules (bypass-blocks per page, consistent-help, landmark completeness)
|
||||
- Cross-project pattern matching
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Seed-based tests (per rule)
|
||||
- Fixture JSX with known violations → assert A11ySignal created
|
||||
- Fixture JSX with no violations → assert no false positive
|
||||
- Break fixture to confirm test catches the change
|
||||
|
||||
### Pipeline-level tests
|
||||
- Synthetic mini-project with JSX components
|
||||
- Assert node/edge counts and signal verdicts
|
||||
|
||||
### Real-repo validation
|
||||
- fluentiagrant-app (rich a11y infrastructure — verify detection matches existing audit)
|
||||
- collector (PHP — verify zero false positives on non-JSX project)
|
||||
- kurz-spj-sk (Next.js — deaf user context)
|
||||
|
||||
### MCP tool smoke tests
|
||||
- Invoke wcag_audit after each implementation phase
|
||||
- Verify output format matches spec
|
||||
|
||||
## Post-Implementation Process (every phase)
|
||||
|
||||
1. Run /simplify on the branch
|
||||
2. Real-repo validation
|
||||
3. Squash duplicate commits
|
||||
4. Audit PR body for private project references
|
||||
5. Push to fork and create PR

* E2E Integration Tests: WCAG Audit Tool
