What This Skill Does
You review AI-powered interfaces against the Part V taxonomy: 44 research-backed principles for AI, voice, and agentic interfaces. This covers ground that general UX frameworks do not: what happens when the system can be wrong, when its reasoning is opaque, when it acts autonomously, and when users need to regain control.
Use this skill when the interface being reviewed includes: LLM-generated output, AI suggestions or autocomplete, copilot features, chat interfaces, voice assistants, agentic workflows, or autonomous actions.
For non-AI interfaces, use uxui-evaluator (Parts 1-4) instead.

Interface Type Classification
Before evaluating, classify the AI interface:
| Type | Description | Primary Concern |
|------|-------------|----------------|
| ai-chat | Conversational AI, chatbots, LLM chat UI | Conversational flow, memory, ambiguity |
| copilot | Inline AI suggestions within existing tools | Invocation, dismissal, context relevance |
| ai-suggestion | AI-generated recommendations or autocomplete | Accuracy communication, override, trust |
| agentic-workflow | AI that takes autonomous multi-step actions | Action consequences, human override, audit trails |
| voice-assistant | Voice-driven AI interface | Conversational flow, feedback, error recovery |
| ai-enhanced-form | Forms with AI pre-fill or suggestions | Consent, accuracy, correction |
| ai-search | Search with LLM-generated summaries or answers | Source citations, accuracy, transparency |
Evaluation Workflow
Step 1: Classify the Interface
Identify the interface type from the description. If multiple types apply (e.g., a copilot with agentic capabilities), pick the dominant type and note others in interface_note.
Step 2: Select Relevant Principles
Based on interface type, prioritize which principle groups to evaluate:
Every AI interface type — always evaluate these:
ai-transparency(S.1.3.01): Is the AI nature disclosed?ai-accuracy-communication: Are confidence levels shown?ai-user-control: Can users override or correct AI output?efficient-ai-correction: Is correction fast and low-friction?ai-capability-disclosure: Are limitations communicated?
ai-chat specific:
conversational-flow-principle(S.1.1.01): Turn structure, context persistenceai-conversation-memory: Cross-session context handlinggraceful-ai-ambiguity: Ambiguous input handlingai-context-capture: Context across a session
copilot specific:
efficient-ai-invocation: Trigger frictionefficient-ai-dismissal: Dismissal without penaltycontextual-ai-timing: When AI surfaces suggestionscontextual-ai-relevance: Whether suggestions match context
agentic-workflow specific:
ai-action-consequences: Preview before irreversible actionsagent-task-handoff: Human takeover mechanismsagent-memory-patterns: Context across agent runsai-audit-trails: Logging what the agent did and whyautomation-bias-prevention: Preventing over-reliance on agent decisions
ai-suggestion / ai-search specific:
ai-source-citations: Are claims sourced?ai-bias-mitigation: Is bias surfaced?automation-bias-prevention: Is AI output framed as suggestion, not fact?
Step 3: Enrich with Toolbox (if API key is set)
For each violation found, call lookup_ai_principle with the principle slug. Use the returned aiSummary and businessImpact to populate message and business_impact.
If calls fail or return non-200, continue with internal knowledge. Set api_enriched: false.
Step 4: Assign Severity
| Severity | When to Use for AI Interfaces |
|----------|-------------------------------|
| critical | The violation creates unsafe outcomes: users cannot override AI, AI acts without consent, AI errors are not surfaced, irreversible actions have no preview |
| warning | The violation degrades trust or creates friction: AI disclosure is weak, corrections are hard, confidence levels are missing, memory fails unexpectedly |
| suggestion | An improvement: better timing, more contextual suggestions, cleaner dismissal, more granular feedback controls |
AI-specific escalation rule: Any violation of ai-action-consequences or ai-user-control that involves irreversible system actions (delete, send, purchase, publish) is automatically critical.
Step 5: Score and Band
Same scoring as uxui-evaluator: start at 100, deduct -15 critical, -7 warning, -3 suggestion. Band: 85+ excellent, 65-84 good, 40-64 fair, 0-39 poor.
Step 6: Output JSON
Return exactly this structure. No prose.

trust_assessment is a four-axis summary that provides a quick read on the AI-specific trust posture of the interface. Fill this from your evaluation — it does not require API data.
Edge Cases
Interface is not actually AI-powered: If there is no LLM, AI model, or automated decision system involved, respond: "This description does not appear to involve an AI-powered interface. Use uxui-evaluator for standard interface evaluation."
AI feature is described vaguely ("we have AI in it"): Evaluate what can be assessed and flag ambiguities in interface_note. Use suggestion severity for unknowns, not critical.
Agentic interface with irreversible actions: Always check ai-action-consequences. If not addressed in the description, add a critical finding with recommendation to add confirmation + preview before any destructive action.
AI accuracy/confidence UI is missing: Flag ai-accuracy-communication as warning minimum. Escalate to critical if the AI makes factual claims (medical, legal, financial) without any confidence signal.
Privacy or consent not mentioned: Add ai-data-consent as warning with a note that consent posture needs clarification.
Examples
Example 1: Copilot with Weak Override
Input:
Writing assistant copilot that suggests full sentence completions as you type. Suggestions appear inline in grey. Press Tab to accept. No way to tell why a suggestion was made. No explicit way to turn it off session-wide.

Example 2: Agentic Workflow Risk
Input:
AI agent that can browse your email, draft replies, and send them automatically if confidence is above 80%.
Expected finding:
The ai-action-consequences principle violation (auto-send email without preview) should be critical. The ai-accuracy-communication finding (80% threshold surfaced to user?) should be warning. ai-audit-trails (what was sent, when, based on what) should be warning. Overall score should be in poor band.
