## Purpose

The Inclusive Design sub-skill provides structured accessibility evaluation using two complementary frameworks: **WCAG 2.2 conformance auditing** (W3C, 2023) and **Microsoft Inclusive Design methodology** (Microsoft, 2016). It targets tiny teams (1-5 people) who need to ensure their products are accessible to the broadest possible range of users while meeting legal compliance requirements (ADA, EAA, Section 508).

This sub-skill is part of Wave 3 (Design System), meaning it requires Wave 2 completion (launched product with analytics OR 1 completed Lean UX hypothesis cycle) before deployment. It pairs with `/ux-atomic-design` in the "Build to Evaluate" canonical sequence: components are built using atomic design principles, then evaluated for accessibility compliance.

### Why Inclusive Design Matters for Tiny Teams

- **Legal compliance** -- The Americans with Disabilities Act (ADA; US DOJ, 2024), European Accessibility Act (EAA, effective June 2025; European Parliament, 2019), and Section 508 (US federal; 29 U.S.C. Section 794d) create legal obligations for digital accessibility. Non-compliance exposes organizations to litigation risk, particularly under Title III ADA case law.
- **Broader user reach** -- Microsoft's Persona Spectrum methodology reveals that designing for permanent disabilities simultaneously benefits users with temporary and situational impairments. Designing for one person with a permanent arm injury also serves someone with a broken arm (temporary) or a parent holding a child (situational). This expands the addressable user base beyond what accessibility compliance alone achieves.
- **Microsoft Inclusive Design principles** -- The methodology operates on three principles: (1) Recognize exclusion -- identify who is being excluded by current design decisions, (2) Solve for one, extend to many -- design for a person in the most constrained scenario and the solution benefits everyone, (3) Learn from diversity -- people with disabilities are experts on adaptation and workarounds that inform better design for all.
- **Cost efficiency** -- Addressing accessibility during design (Wave 3) is significantly less expensive than retrofitting after launch. Teams that evaluate accessibility alongside component design avoid the accumulation of accessibility debt.

### Key Capabilities

- **WCAG 2.2 Compliance Auditing** -- Systematic evaluation against WCAG 2.2 success criteria across four principles (Perceivable, Operable, Understandable, Robust) at conformance levels A, AA, and AAA
- **Persona Spectrum Analysis** -- Application of Microsoft Inclusive Design Persona Spectrum methodology to map permanent, temporary, and situational disability scenarios for each interaction pattern
- **Color Contrast Evaluation** -- Assessment of text and UI component color contrast ratios against WCAG 2.2 success criteria 1.4.3 (AA: 4.5:1 normal text, 3:1 large text) and 1.4.6 (AAA: 7:1 normal text, 4.5:1 large text)
- **Keyboard Navigation Assessment** -- Evaluation of keyboard-only operability including focus order, focus visibility, keyboard traps, and shortcut key conflicts per WCAG 2.2 Operable principle
- **Screen Reader Compatibility Review** -- Assessment of semantic HTML structure, ARIA landmark roles, live region announcements, and alternative text adequacy for assistive technology compatibility
- **Cognitive Load Assessment** -- Evaluation of information density, reading level, consistent navigation patterns, error prevention mechanisms, and input assistance per WCAG 2.2 Understandable principle

## When to Use This Sub-Skill

Activate when:

- Auditing an existing interface or component for WCAG 2.2 conformance at A, AA, or AAA level
- Evaluating color contrast ratios for text, UI components, and graphical objects
- Assessing keyboard navigation completeness and focus management
- Reviewing screen reader compatibility and ARIA implementation
- Performing a Persona Spectrum analysis to map permanent, temporary, and situational disability scenarios
- Evaluating cognitive load and understandability of an interface
- Checking accessibility of components from an atomic design system (Build to Evaluate sequence)
- Responding to "Any stage: Check accessibility" routing from the ux-orchestrator
- Preparing accessibility documentation for legal compliance (ADA, EAA, Section 508)

Do NOT use for:

- Evaluating general usability heuristics beyond accessibility -- use `/ux-heuristic-eval` (Nielsen's 10) instead. Inclusive Design focuses specifically on accessibility; general usability evaluation is a broader scope.
- Building or cataloging a component library -- use `/ux-atomic-design` instead. Inclusive Design evaluates accessibility of components; it does not build the component taxonomy.
- Measuring quantitative UX health metrics -- use `/ux-heart-metrics` (Google GSM) instead. Inclusive Design produces qualitative accessibility findings; HEART Metrics produces ongoing measurement baselines.
- Designing experiments to test design changes -- use `/ux-lean-ux` instead. Inclusive Design evaluates current state; Lean UX tests hypotheses about changes.
- Diagnosing behavioral bottlenecks -- use `/ux-behavior-design` (Fogg B=MAP) instead. Inclusive Design evaluates accessibility barriers; behavior design diagnoses motivation/ability/prompt bottlenecks.
- Security-focused interface review or threat modeling -- use `/eng-team` instead.
- General research without accessibility focus -- use `/problem-solving` instead.

## Available Agents

| Agent | Role | Tier | Mode | Model | Output Location |
|-------|------|------|------|-------|-----------------|
| `ux-inclusive-evaluator` | Inclusive design and WCAG 2.2 accessibility auditor | T4 | Systematic | Sonnet | `projects/${JERRY_PROJECT}/engagements/{engagement-id}/ux-inclusive-evaluator-{topic-slug}.md` |

**STUB:** The agent definition file (`skills/ux-inclusive-design/agents/ux-inclusive-evaluator.md`) is planned for creation during Wave 3 implementation of PROJ-022 EPIC-004. The SKILL.md specifies the methodology and output contract that the agent will implement. Agent definition file and governance YAML will contain frontmatter, identity, purpose, guardrails, and full body sections (`<input>`, `<capabilities>`, `<methodology>`, `<output>`).

**Tool tier:** T4 (External) = Read, Write, Edit, Glob, Grep + WebSearch, WebFetch + Context7 MCP. The T4 tier enables access to external WCAG specifications, ARIA authoring practices, and accessibility API documentation via Context7 and web search. Bash is intentionally excluded; T4 tier does not require shell access for MCP operations. See `agent-development-standards.md` [Tool Security Tiers] for full tier definitions.

The agent produces output at three levels per AD-M-004:
- **L0 (Executive Summary):** Conformance level achieved (A, AA, AAA, or none); critical WCAG violations count; Persona Spectrum coverage summary; top remediation priorities for stakeholders and cross-framework synthesis input.
- **L1 (Technical Detail):** Full WCAG 2.2 success criteria evaluation by principle (POUR), per-criterion pass/fail with evidence, Persona Spectrum profiles for each interaction pattern, color contrast ratio measurements, keyboard navigation audit, screen reader compatibility findings, and remediation recommendations with WCAG success criteria references.
- **L2 (Strategic Implications):** Organizational accessibility maturity assessment, legal compliance gap analysis (ADA, EAA, Section 508), accessibility debt quantification, inclusive design adoption roadmap, and cross-product accessibility pattern analysis.

## P-003 Compliance

The `/ux-inclusive-design` sub-skill contains a single **worker** agent. It is invoked by the `ux-orchestrator` (T5) via the Agent tool. The agent does NOT have Agent tool access and MUST NOT spawn sub-agents.

```
MAIN CONTEXT (user request)
    |
    v
ux-orchestrator (T5, Opus, Integrative) -- parent orchestrator
    |
    +-- ux-inclusive-evaluator (T4, Systematic, Sonnet) -- THIS sub-skill's worker
    +-- [other sub-skill workers...]
```

**Enforcement:**
- `disallowedTools: [Agent]` declared in `skills/ux-inclusive-design/agents/ux-inclusive-evaluator.md` frontmatter
- P-003 prohibition in `skills/ux-inclusive-design/agents/ux-inclusive-evaluator.governance.yaml` `capabilities.forbidden_actions`
- CI gate validates no sub-skill agent has Agent access (documented in `skills/user-experience/rules/ci-checks.md`)

## Invoking the Agent

This is a sub-skill invoked by the `ux-orchestrator`, not directly by users. Users interact with the parent `/user-experience` skill, which routes to this sub-skill based on lifecycle-stage triage.

### Via Natural Language (to parent skill)

```
"Audit this page for WCAG 2.2 AA compliance"
"Check the color contrast on our form components"
"Review this interface for screen reader compatibility"
"Map the persona spectrum for our checkout flow"
"Evaluate cognitive load on the settings page"
"Make this accessible"
```

The `ux-orchestrator` routes these requests to `ux-inclusive-evaluator` based on [skills/user-experience/rules/ux-routing-rules.md -- Stage Routing Table]. Specifically, the "Any stage: Check accessibility" route maps directly to `/ux-inclusive-design` without qualification question (source: [skills/user-experience/SKILL.md -- Common Intent-to-Route Resolution]).

### Via Explicit Agent Request (to parent skill)

```
"Use ux-inclusive-evaluator to review color contrast and screen reader compatibility"
"Have ux-inclusive-evaluator perform a WCAG 2.2 AAA audit of the navigation"
```

### Via Agent Tool (orchestrator internal)

The `ux-orchestrator` invokes the agent via the Agent tool:

```python

## Methodology

### Dual-Framework Approach

The evaluator applies two complementary frameworks in sequence:

1. **WCAG 2.2 Compliance Audit** -- Systematic, criterion-by-criterion evaluation against the W3C Web Content Accessibility Guidelines 2.2 (2023). Produces deterministic pass/fail results per success criterion.
2. **Microsoft Inclusive Design** -- Persona Spectrum analysis that maps each interaction pattern to permanent, temporary, and situational disability scenarios. Produces qualitative insights about who is excluded and how to extend solutions.

The dual-framework approach ensures both compliance coverage (WCAG addresses "what must be met") and design thinking coverage (Inclusive Design addresses "who is being excluded and why").

### WCAG 2.2 Compliance Audit

WCAG 2.2 organizes accessibility requirements into four principles (POUR), each containing guidelines with testable success criteria at three conformance levels (A, AA, AAA).

#### Four Principles (POUR)

| Principle | Letter | Focus | Example Guidelines |
|-----------|--------|-------|-------------------|
| **Perceivable** | P | Information and UI components must be presentable in ways users can perceive | Text alternatives (1.1), time-based media (1.2), adaptable content (1.3), distinguishable presentation (1.4) |
| **Operable** | O | UI components and navigation must be operable by all users | Keyboard accessible (2.1), enough time (2.2), seizure-safe (2.3), navigable (2.4), input modalities (2.5) |
| **Understandable** | U | Information and UI operation must be understandable | Readable (3.1), predictable (3.2), input assistance (3.3) |
| **Robust** | R | Content must be robust enough for reliable interpretation by assistive technologies | Compatible with current and future user agents (4.1) |

#### Conformance Levels

| Level | Scope | Typical Target | Legal Requirement |
|-------|-------|---------------|-------------------|
| **A** | Minimum accessibility -- addresses the most critical barriers | Minimum legal floor in some jurisdictions | ADA (case law baseline) |
| **AA** | Standard compliance target -- removes significant barriers for most users | Most common target for organizations | EAA (explicit requirement), Section 508 (federal), ADA (recommended) |
| **AAA** | Enhanced accessibility -- addresses barriers for specialized user needs | Aspirational; rarely achievable across an entire site | Not typically required by law; recommended for specific content types |

#### Success Criteria Evaluation Format

Each WCAG success criterion is evaluated using the following format:

```
### SC {X.Y.Z}: {Success Criterion Name} [{Level}]

- **Status:** PASS | FAIL | NOT APPLICABLE
- **Evidence:** {specific observation, measurement, or test result}
- **Affected Elements:** {UI element references, selectors, or screen locations}
- **Severity:** 0 (not a problem) | 1 (cosmetic) | 2 (minor barrier) | 3 (major barrier) | 4 (critical -- blocks access)
- **Remediation:** {specific fix with WCAG technique reference, e.g., "Apply ARIA-label per Technique ARIA14"}
```

The severity scale aligns with Nielsen's severity rating scale (Nielsen, 1994b) to enable cross-framework synthesis with `/ux-heuristic-eval` findings. Severity 0 in this sub-skill means "not an accessibility barrier" (equivalent to Nielsen's "not a usability problem" at severity 0); levels 1-4 maintain direct semantic correspondence between the two scales (1=cosmetic/minor, 2=minor barrier, 3=major barrier/usability problem, 4=critical/catastrophe). **Note:** While WCAG pass/fail status is a deterministic compliance check, the severity assignment (0-4) for each finding involves AI judgment about user impact and is classified as MEDIUM synthesis confidence (see [Synthesis Hypothesis Confidence](#synthesis-hypothesis-confidence)).

### Microsoft Inclusive Design

Microsoft Inclusive Design methodology (Microsoft, 2016) complements WCAG compliance with a design-thinking approach that broadens the understanding of who benefits from accessible design.

#### Three Principles

| Principle | Description | Application |
|-----------|-------------|-------------|
| **Recognize exclusion** | Identify who is being excluded by current design decisions and how | For each interaction pattern, identify users who cannot complete the task due to permanent, temporary, or situational impairments |
| **Solve for one, extend to many** | Design for a person in the most constrained scenario; the solution benefits everyone | Remediation recommendations target the permanent disability scenario; benefits to temporary and situational users are documented |
| **Learn from diversity** | People who adapt to exclusion develop expertise that informs better design | Persona Spectrum profiles include adaptation strategies observed in the disability community |

#### Persona Spectrum Methodology

The Persona Spectrum maps each interaction pattern across three disability duration categories:

| Duration | Definition | Example (Visual) | Example (Motor) | Example (Auditory) | Example (Cognitive) |
|----------|-----------|-------------------|-----------------|--------------------|--------------------|
| **Permanent** | Long-term or lifelong disability | Blind user | Single arm user | Deaf user | Learning disability |
| **Temporary** | Short-term impairment due to injury, surgery, or condition | Post-cataract surgery | Arm in cast | Ear infection | Concussion |
| **Situational** | Context-dependent limitation due to environment or activity | Glare on screen outdoors | Carrying grocery bags | Loud restaurant | Distracted by children |

For each interaction pattern evaluated, the agent produces a Persona Spectrum profile:

```
### Persona Spectrum: {Interaction Pattern Name}

**Interaction:** {description of the user task/action}

| Disability Type | Permanent | Temporary | Situational |
|----------------|-----------|-----------|-------------|
| **Visual** | {scenario} | {scenario} | {scenario} |
| **Motor** | {scenario} | {scenario} | {scenario} |
| **Auditory** | {scenario} | {scenario} | {scenario} |
| **Cognitive** | {scenario} | {scenario} | {scenario} |

**Exclusion Points:** {specific design decisions that create barriers}
**Design Opportunity:** {how solving for permanent extends to all}
**Current Compliance:** {WCAG success criteria relevant to this pattern}
```

### Accessibility Testing Protocols

The evaluator applies the following testing protocols to produce evidence for WCAG findings:

#### Color Contrast Assessment

| Test | Method | Threshold (AA) | Threshold (AAA) | WCAG Criterion |
|------|--------|----------------|-----------------|----------------|
| Normal text contrast | Compute luminance ratio of foreground/background colors | >= 4.5:1 | >= 7:1 | 1.4.3 / 1.4.6 |
| Large text contrast | Large text: >= 18pt or >= 14pt bold | >= 3:1 | >= 4.5:1 | 1.4.3 / 1.4.6 |
| UI component contrast | Non-text UI components and graphical objects | >= 3:1 | >= 3:1 | 1.4.11 |
| Focus indicator contrast | Focus visible indicator against adjacent colors | >= 3:1 | >= 3:1 | 2.4.11 (new in 2.2) |

**Note on programmatic evaluation:** In text-only mode (Figma MCP unavailable), the evaluator cannot compute exact contrast ratios from design artifacts. In this mode, the evaluator documents color values provided by the user and applies the ratio formula, or flags elements where contrast appears insufficient based on visual inspection of screenshots. Exact ratios require hex/RGB values.

#### Keyboard Navigation Audit

| Test | Evaluation Criteria | WCAG Criterion |
|------|-------------------|----------------|
| Tab order completeness | All interactive elements reachable via Tab/Shift+Tab | 2.1.1 (A) |
| Focus visibility | Focus indicator visible on all focused elements | 2.4.7 (AA), 2.4.11 (AA, new in 2.2) |
| No keyboard traps | Focus can be moved away from all components | 2.1.2 (A) |
| Shortcut conflicts | Single character key shortcuts can be turned off or remapped | 2.1.4 (A, new in 2.1) |
| Skip navigation | Skip-to-content mechanism available | 2.4.1 (A) |
| Focus not obscured | Focused element not fully hidden by other content | 2.4.12 (AA, new in 2.2) |

#### Screen Reader Compatibility Review

| Test | Evaluation Criteria | WCAG Criterion |
|------|-------------------|----------------|
| Heading hierarchy | Logical heading structure (h1-h6) without skipped levels | 1.3.1 (A) |
| ARIA landmarks | Main, navigation, banner, contentinfo landmarks present and correct | 1.3.1 (A), 4.1.2 (A) |
| Alternative text | All non-decorative images have descriptive alt text; decorative images use empty alt | 1.1.1 (A) |
| Form labels | All form controls have programmatically associated labels | 1.3.1 (A), 3.3.2 (A) |
| Live regions | Dynamic content updates announced via ARIA live regions | 4.1.3 (AA) |
| Error identification | Error messages programmatically associated with the invalid field | 3.3.1 (A) |

#### Cognitive Load Assessment

| Test | Evaluation Criteria | WCAG Criterion |
|------|-------------------|----------------|
| Reading level | Content appropriate for the target audience's reading level (evaluate via Flesch-Kincaid readability formula where text is available; otherwise AI-assisted reading level assessment -- flag as MEDIUM synthesis confidence per [Synthesis Hypothesis Confidence](#synthesis-hypothesis-confidence)) | 3.1.5 (AAA) |
| Consistent navigation | Navigation mechanisms consistent across pages/screens | 3.2.3 (AA) |
| Error prevention | Reversible submissions; confirmation for consequential actions | 3.3.4 (AA), 3.3.6 (AAA) |
| Input assistance | Labels, instructions, and suggestions provided for user input | 3.3.2 (A), 3.3.3 (AA) |
| Redundant entry | Information previously entered is auto-populated or selectable | 3.3.7 (A, new in 2.2) |
| Consistent help | Help mechanisms in consistent relative order across pages | 3.2.6 (A, new in 2.2) |

## MCP Dependencies

### Dependency Matrix

| MCP Tool | Classification | Purpose | Fallback |
|----------|---------------|---------|----------|
| **Figma** | **REQ** | Inspect design layers, extract color values for contrast computation, examine component states and responsive behavior, access design token definitions | Screenshot-input mode: user provides design screenshots as image inputs; color values provided manually for contrast computation |
| **Storybook** | ENH | Browse component stories to evaluate accessibility of interactive states, inspect component markup for ARIA implementation | Manual component inventory: user provides component list, markup samples, and documentation links |
| **Context7** | Available (current infrastructure) | Resolve and query WCAG 2.2 success criteria documentation, ARIA Authoring Practices Guide (APG), accessibility API documentation | WebSearch fallback per MCP-001 (`mcp-tool-standards.md` [Error Handling]) |

### Figma Fallback: Screenshot-Input Mode

When the Figma MCP adapter is unavailable (current state -- adapter implementation is post-PROJ-022 scope), the evaluator operates in screenshot-input mode:

- Design evaluation is performed from user-provided screenshot images
- Color contrast ratios require manually provided hex/RGB color values (cannot be extracted programmatically from screenshots)
- Component state evaluation (hover, focus, active, disabled) requires separate screenshots per state
- Responsive behavior assessment requires screenshots at multiple breakpoints
- **Limitations in screenshot-input mode:**
  - Cannot inspect design layers or component hierarchy programmatically
  - Cannot extract exact color values for automated contrast ratio computation
  - Cannot evaluate interactive states (animations, transitions, dynamic content)
  - Cannot access design token definitions or systematic color palette information
- Output carries a degraded mode disclosure per P-022:
  ```
  [DEGRADED MODE] This output was produced without Figma MCP access.
  Input was provided via screenshot-input mode. Some features are reduced:
  - Cannot inspect design layers or component hierarchy programmatically
  - Cannot extract exact color values for automated contrast ratio computation
  - Cannot evaluate interactive states (animations, transitions, dynamic content)
  - Cannot access design token definitions or systematic color palette information
  ```

### Context7 Usage

Per MCP-001 (`.context/rules/mcp-tool-standards.md` [Context7 Integration]), Context7 is used when the evaluation references external accessibility standards, ARIA patterns, or component library documentation by name:

| Library/Framework | Usage |
|-------------------|-------|
| WCAG 2.2 | Success criteria definitions, techniques, sufficient and advisory techniques references |
| ARIA Authoring Practices Guide (APG) | Design pattern implementations for accessible widgets (tabs, dialogs, menus, comboboxes) |
| ARIA specification | Role, state, and property definitions for assistive technology communication |
| Material UI / Radix UI / similar | Component accessibility API documentation for specific design system libraries |

Protocol: call `mcp__context7__resolve-library-id` with the framework name, then `mcp__context7__query-docs` with the resolved ID and specific query. If Context7 returns no results, fall back to WebSearch per `mcp-tool-standards.md` [Error Handling].

**Synthesis Judgments Summary requirements:** This section MUST list every AI-generated judgment (Persona Spectrum customization, severity assignment, remediation priority ranking, cognitive load assessment) with a confidence classification (HIGH, MEDIUM, LOW) and a one-line rationale. This enables downstream consumers (including the `ux-orchestrator` synthesis gate) to assess which findings are strongly supported versus which require additional validation. The format follows the synthesis judgments pattern established in `skills/user-experience/rules/synthesis-validation.md`.

## Routing

### Trigger Keywords

| Keyword | Routing Context |
|---------|----------------|
| accessibility | Direct match -- primary trigger |
| WCAG | Direct match |
| WCAG 2.2 | Direct match |
| ARIA | Direct match |
| screen reader | Direct match |
| contrast | In combination with UX/design/accessibility context |
| cognitive load | In combination with accessibility context |
| inclusive design | Direct match |
| a11y | Direct match |
| persona spectrum | Direct match |

### Lifecycle-Stage Routing Integration

This sub-skill is routed to by the `ux-orchestrator` in the following lifecycle-stage scenarios:

| Stage | User Intent | Route Condition |
|-------|-------------|-----------------|
| Any stage | "Check accessibility" | No qualification needed -- direct route to `/ux-inclusive-design` per [skills/user-experience/SKILL.md -- Lifecycle-Stage Routing] |
| Any stage | "Make this accessible" | No qualification needed -- routes directly; source: [skills/user-experience/SKILL.md -- Common Intent-to-Route Resolution] |
| During design | "Building component system" | In "Build to Evaluate" sequence: routes to `/ux-atomic-design` first, then `/ux-inclusive-design` for accessibility evaluation of the component inventory |
| Any stage | After `/ux-atomic-design` completion | Canonical sequence continuation: component inventory available as upstream handoff artifact |

### Wave Gating

This sub-skill is in **Wave 3** (Design System). It requires Wave 2 completion before deployment:

**Entry criteria:** Wave 2: launched product with analytics OR 1 completed Lean UX hypothesis cycle.

**Bypass condition:** Storybook already in use (skip Lean UX prerequisite for Atomic Design). Note: this bypass condition is defined for the Wave 3 pair (`/ux-atomic-design` and `/ux-inclusive-design`); the bypass allows teams with an existing component system to proceed to Wave 3 without completing Lean UX cycles.

## Cross-Framework Integration

### Upstream Inputs

This sub-skill receives context from other sub-skills when invoked as part of a multi-sub-skill workflow:

| From Sub-Skill | Handoff Artifact | Key Fields | Usage |
|----------------|-----------------|-----------|-------|
| `/ux-atomic-design` | Component inventory with Storybook references | Component taxonomy (atoms, molecules, organisms, templates, pages), Storybook story references, design token definitions | Component inventory provides the evaluation scope for accessibility audit; Storybook references enable component-level accessibility testing; design tokens inform color contrast evaluation |
| `/ux-heuristic-eval` | Severity-rated findings with accessibility subset | Finding ID, heuristic violated (especially H4: Consistency and Standards, H7: Flexibility and Efficiency of Use, H10: Help and Documentation), severity (0-4), affected screen/flow | Heuristic findings related to accessibility (keyboard navigation, error visibility, consistent interface) provide context for targeted WCAG evaluation; severity ratings enable cross-framework convergence detection |

### Downstream Handoffs

This sub-skill produces artifacts that feed into cross-framework synthesis via the Jerry handoff protocol (`docs/schemas/handoff-v2.schema.json`).

| To Sub-Skill/Consumer | Handoff Artifact | Key Fields | Trigger |
|-----------------------|-----------------|-----------|---------|
| `ux-orchestrator` (synthesis) | WCAG findings + Persona Spectrum analysis | Conformance result, WCAG findings with criterion references, persona spectrum profiles, remediation priorities | After audit completion; findings feed cross-framework synthesis for convergence detection with heuristic eval and other sub-skill outputs |
| `/eng-team` (cross-skill) | Accessibility requirements for security integration | WCAG AA violations, ARIA implementation gaps, keyboard trap findings | When engineering team needs accessibility requirements for secure frontend patterns (source: [skills/user-experience/SKILL.md -- Cross-Skill Integration], `/eng-team` integration) |

**Handoff threshold:** Only findings with severity >= 2 (minor barrier or above) are included in cross-framework synthesis handoffs. Severity 0 (not a problem) and severity 1 (cosmetic) findings remain in the full audit report but are excluded from synthesis signal extraction to prevent noise in convergence detection.

### Canonical Multi-Skill Workflow Sequences

This sub-skill participates in the following canonical sequences:

| Sequence | Skills Involved | This Sub-Skill's Role |
|----------|----------------|-----------------------|
| Build to Evaluate | `/ux-atomic-design` then **`/ux-inclusive-design`** | Receives component inventory from Atomic Design; evaluates each component level (atoms through pages) for WCAG compliance and Persona Spectrum coverage |
| Evaluate to Diagnose to Measure | `/ux-heuristic-eval` then **`/ux-inclusive-design`** (accessibility subset) then `/ux-behavior-design` | Heuristic eval identifies accessibility-related findings; inclusive design provides detailed WCAG audit for those areas; behavior design diagnoses why accessibility barriers cause user drop-off |

> **Source:** Handoff data contracts from [skills/user-experience/rules/ux-routing-rules.md -- Handoff Data Contracts] and [skills/user-experience/SKILL.md -- Cross-Sub-Skill Handoff Data] ("/ux-atomic-design -> /ux-inclusive-design: Component inventory with Storybook references"). Canonical sequences from [skills/user-experience/SKILL.md -- Canonical Multi-Skill Workflow Sequences] ("Build to Evaluate: /ux-atomic-design then /ux-inclusive-design").

## Synthesis Hypothesis Confidence

Inclusive Design outputs include synthesis hypotheses that carry confidence classifications per the synthesis validation protocol.

| Synthesis Step | Typical Confidence | Rationale |
|---------------|-------------------|-----------|
| Persona Spectrum customization | MEDIUM | Persona Spectrums are heuristic models (Microsoft, 2016), not empirical profiles; the mapping of permanent/temporary/situational scenarios involves AI judgment about plausible user contexts rather than observed user data |
| Severity assignment (0-4 scale) | MEDIUM | Severity ratings involve AI interpretation of user impact against the Nielsen severity scale (Nielsen, 1994b); while WCAG pass/fail is deterministic, mapping a failure to a 0-4 severity level requires judgment about how much the barrier impedes real user tasks -- no objective algorithm exists for this mapping |
| Remediation priority ranking | MEDIUM | Prioritization requires AI judgment about relative user impact severity, affected population size, and estimated implementation effort (W3C, 2023; Microsoft, 2016); these factors are context-dependent and cannot be deterministically computed from WCAG criteria alone |
| Cognitive load assessment | MEDIUM | Reading level evaluation and information density assessments are heuristic (Nielsen, 1994b); readability formulas provide approximate guidance but the determination of whether content is "appropriate for the target audience" (WCAG 3.1.5) requires AI judgment about audience characteristics |

**Gate enforcement:**
- **MEDIUM outputs:** Include a "Validation Required" section. Design recommendations derived from Persona Spectrum analysis, severity assignments, remediation priority rankings, and cognitive load assessments are withheld until validation against real user observation, assistive technology user testing, or accessibility expert review is provided. Persona Spectrum profiles serve as structured hypotheses about who is excluded, not as validated user research findings. Severity and priority assignments serve as structured triage guidance, not as definitive impact measurements.

**Note on WCAG findings confidence:** WCAG 2.2 success criteria evaluations (pass/fail per criterion) do not go through the synthesis hypothesis confidence gate because they are deterministic compliance checks, not AI-generated abstractions. A WCAG criterion either passes or fails based on measurable criteria (W3C, 2023). However, the severity assignment (0-4) for each finding involves AI judgment and is classified as MEDIUM confidence in the table above. Persona Spectrum analysis, by contrast, is inherently interpretive and always receives MEDIUM confidence.

**Confidence upgrade path:** Persona Spectrum customization, severity assignment, and remediation priority confidence can increase to HIGH only through convergence with a second framework in cross-framework synthesis (per `skills/user-experience/rules/synthesis-validation.md` [Convergence Thresholds]: moderate convergence = 2 frameworks identifying the same problem with supporting evidence = HIGH). For example, if Persona Spectrum analysis identifies "situational visual impairment: glare on screen outdoors" as an exclusion point AND Heuristic Eval independently identifies low contrast as a severity-3 finding for the same component, the convergent finding receives HIGH synthesis confidence. Similarly, severity and priority assignments that align with quantitative HEART Metrics data (e.g., low Task Success rate confirms a severity-4 barrier) receive HIGH confidence through cross-framework corroboration.

## Constitutional Compliance

All agents in this sub-skill adhere to the **Jerry Constitution v1.0**:

| Principle | Requirement | Consequence of Violation |
|-----------|-------------|-------------------------|
| P-003 | NEVER spawn recursive subagents -- worker agent, no Agent tool access | Agent hierarchy violation; uncontrolled token consumption |
| P-020 | NEVER override user decisions on target conformance level or remediation priority | Unauthorized action; trust erosion |
| P-022 | NEVER present WCAG pass/fail status without evidence; NEVER inflate conformance claims without criterion-level verification | Governance undermined; legal compliance assessment invalidated |
| P-001 | NEVER present accessibility findings without WCAG success criteria references or Persona Spectrum evidence | Unreliable outputs; unfounded compliance claims propagate downstream |
| P-002 | NEVER leave accessibility audit results or persona spectrum analyses in transient context only -- persist to files | Context rot vulnerability; artifacts lost on session compaction |

**Per-agent enforcement:** The `ux-inclusive-evaluator` agent declares:
- `constitution.principles_applied`: P-003, P-020, P-022, P-001, P-002 in `skills/ux-inclusive-design/agents/ux-inclusive-evaluator.governance.yaml`
- `capabilities.forbidden_actions`: 3 entries in NPT-009 format referencing the constitutional triplet
- `disallowedTools: [Agent]` in `skills/ux-inclusive-design/agents/ux-inclusive-evaluator.md` frontmatter

### AI-Augmented Analysis Limitations

The Inclusive Design evaluator agent operates as an AI-augmented analysis tool. The following limitations apply to all outputs and MUST be disclosed per P-022 (no deception):

- **WCAG evaluation is best-effort from available artifacts.** Full WCAG compliance testing requires manual testing with assistive technologies (screen readers, switch devices, voice control), automated testing tools (axe-core, Lighthouse, WAVE), and user testing with people who have disabilities. AI-based evaluation from design artifacts or screenshots provides a structured initial audit but does not replace comprehensive accessibility testing.
- **Persona Spectrum profiles are heuristic models.** The mapping of permanent, temporary, and situational disability scenarios is based on the Microsoft Inclusive Design Toolkit methodology and general knowledge of disability contexts. Real Persona Spectrums should be informed by interviews with people who have disabilities and observation of actual assistive technology usage.
- **Color contrast ratios are input-dependent.** In screenshot-input mode (Figma MCP unavailable), exact contrast ratios require user-provided hex/RGB values. Visual estimation from screenshots is not precise enough for compliance determination.
- **Screen reader compatibility is structural, not experiential.** The evaluator assesses semantic HTML structure and ARIA implementation from markup or descriptions, but cannot simulate the actual screen reader experience across different assistive technology combinations (JAWS, NVDA, VoiceOver with different browsers).
- **Always validate with real assistive technology users.** Accessibility audit outputs should be confirmed through manual testing with assistive technologies and, where possible, user testing with people who have disabilities before making compliance claims.

## Registration

This sub-skill follows a parent-routed registration model. Sub-skills are not independently registered in `CLAUDE.md` or `mandatory-skill-usage.md` because they are routed through the parent `/user-experience` orchestrator (`ux-orchestrator`). This is an explicit exception to the H-26 registration requirement (parent-routed model): parent skills own the CLAUDE.md and mandatory-skill-usage.md registration; sub-skills are discovered and dispatched by the parent orchestrator's internal routing logic.

| Registration Point | Status | Detail |
|--------------------|--------|--------|
| `CLAUDE.md` skill table | Registered via parent | `/user-experience` is registered in `CLAUDE.md`; sub-skills are not independently listed |
| `mandatory-skill-usage.md` trigger map | Routed via parent | The `/user-experience` trigger map row includes "accessibility" and "inclusive design" as positive keywords (H-22); requests matching these keywords route to the parent skill, which dispatches to this sub-skill |
| `AGENTS.md` agent registry | Registered | `ux-inclusive-evaluator` is listed in `AGENTS.md` under the User-Experience Skill Agents section |
| Parent SKILL.md agent table | Registered | `ux-inclusive-evaluator` is listed in `skills/user-experience/SKILL.md` [Available Agents] |

> **H-26 parent-routed model rationale:** Independent registration of sub-skills would create duplicate trigger map entries and ambiguous routing (AP-02 Bag of Triggers). The parent orchestrator owns lifecycle-stage routing logic and dispatches to the correct sub-skill based on triage qualification, not keyword matching alone. Sub-skill agents are registered in `AGENTS.md` for discoverability but routing flows through the parent.

## Deployment Status

> **Wave 3 Sub-Skill -- Planned.** This sub-skill is part of Wave 3 (Design System) of PROJ-022. The companion agent file (`skills/ux-inclusive-design/agents/ux-inclusive-evaluator.md`) and governance file (`skills/ux-inclusive-design/agents/ux-inclusive-evaluator.governance.yaml`) are planned for creation during Wave 3 implementation of PROJ-022 EPIC-004. The SKILL.md itself is complete and specifies the methodology, output format, and routing integration that the agent will implement.
