Load references/ux-heuristics.md and references/ux-psychology.md. Triggers on: ux review, heuristic evaluation, usability audit, cognitive load, mental models, affordances, dark patterns, review this design, check usability, is this good UX\n---\n\n## UX Review Mode\n\nWhen the user wants to evaluate usability rather than generate visuals, switch to UX Review mode. Load `references/ux-heuristics.md` and `references/ux-psychology.md`. Load additional references as the review scope demands (see \"When to Load Which Reference\" below).\n\n### Triggers\n\n| User says | Action | Load |\n|---|---|---|\n| \"ux review\" / \"heuristic review\" / \"usability audit\" | Full heuristic evaluation against Nielsen's 10 | `ux-heuristics.md` + `ux-psychology.md` |\n| \"review this design\" / \"what's wrong with this UI\" | Heuristic scan → findings list with severity | `ux-heuristics.md` |\n| \"check usability\" / \"is this good UX\" | Walk through flow, flag violations | `ux-heuristics.md` + `ux-psychology.md` |\n| \"cognitive load\" / \"too complex?\" | Cognitive load analysis → reduction suggestions | `ux-psychology.md` |\n| \"why do users get confused here\" | Mental model analysis → mismatch diagnosis | `ux-psychology.md` |\n| \"affordances\" / \"does this look clickable\" | Affordance/signifier audit | `ux-psychology.md` |\n| \"dark patterns\" / \"is this ethical\" | Dark pattern scan | `ux-psychology.md` |\n| \"navigation\" / \"can't find\" / \"information architecture\" / \"IA\" | IA audit — labels, hierarchy, findability | `ux-information-architecture.md` |\n| \"site structure\" / \"how to organize\" / \"card sort\" / \"tree test\" | IA design or validation | `ux-information-architecture.md` |\n| \"accessibility\" / \"a11y\" / \"screen reader\" / \"keyboard navigation\" | Accessibility audit against WCAG 2.1 AA | `ux-accessibility.md` |\n| \"WCAG\" / \"alt text\" / \"aria\" / \"focus\" | Specific accessibility check | `ux-accessibility.md` |\n| \"user testing\" / \"how to test this\" / \"usability test\" | Research method recommendation + test plan | `ux-research-methods.md` |\n| \"what do users think\" / \"how do I get feedback\" | Research method selection | `ux-research-methods.md` |\n| \"NPS\" / \"SUS\" / \"survey\" / \"interview users\" | Measurement framework or interview guidance | `ux-research-methods.md` |\n| \"transition feels wrong\" / \"animation timing\" / \"state choreography\" / \"loading feels laggy\" | Component transition audit | `ux-interaction-transitions.md` |\n| \"touch target\" / \"thumb zone\" / \"mobile gesture\" / \"iOS vs Android\" | Mobile interaction audit | `ux-mobile-patterns.md` |\n| \"onboarding\" / \"empty state\" / \"first use\" / \"aha moment\" / \"activation\" | Onboarding flow review | `ux-onboarding.md` |\n| \"chart\" / \"dashboard\" / \"data viz\" / \"KPI card\" / \"which chart\" | Data visualization audit or recommendation | `ux-data-visualization.md` |\n| \"content model\" / \"taxonomy\" / \"multilingual\" / \"RTL\" / \"localization\" | Content structure review | `ux-content-strategy.md` |\n| \"design tokens\" / \"token naming\" / \"theming\" / \"dark mode architecture\" | Token architecture review | `ux-design-tokens.md` |\n| \"component spec\" / \"button states\" / \"modal behavior\" / \"ARIA\" | Component spec review | `ux-component-specs.md` |\n| \"design critique\" / \"feedback on design\" / \"design review meeting\" | Critique framework guidance | `ux-design-critique.md` |\n| \"conversion\" / \"landing page\" / \"trust signals\" / \"CTA copy\" / \"pricing page\" | Conversion UX audit | `ux-conversion-patterns.md` |\n| \"error message\" / \"error state\" / \"form error\" / \"validation\" / \"recovery path\" / \"prevent errors\" | Error design audit — classification, messaging, prevention | `ux-error-design.md` |\n| \"empty state\" / \"no data\" / \"blank state\" / \"nothing here\" / \"zero state\" | Empty state design — all 4 types | `ux-empty-states.md` |\n| \"notification\" / \"toast\" / \"banner\" / \"badge\" / \"push notification\" / \"alert priority\" | Notification system design and priority rules | `ux-notifications.md` |\n| \"table\" / \"data table\" / \"sorting\" / \"filtering\" / \"pagination\" / \"bulk select\" / \"row actions\" | Table and list interaction design | `ux-tables-lists.md` |\n| \"search\" / \"autocomplete\" / \"search results\" / \"search bar\" / \"faceted search\" / \"command palette\" | Search pattern design — input, suggestions, results | `ux-search-patterns.md` |\n\n### UX Review Workflow\n\nTwo paths depending on what's available:\n- **Code in cwd** → run Code Scan (Steps 1a–1b) first, then layer conceptual analysis\n- **No code / screenshots / description only** → skip to Step 2\n\n**Step 1a: Auto-detect project files**\n\n```bash\n# Find component files in cwd (skip node_modules, .git, dist)\nfind . \\( -name \"*.tsx\" -o -name \"*.jsx\" -o -name \"*.vue\" -o -name \"*.svelte\" -o -name \"*.html\" \\) \\\n -not -path \"*/node_modules/*\" -not -path \"*/.git/*\" -not -path \"*/dist/*\" | head -30\n```\n\nIf files found, proceed to Step 1b. Otherwise skip to Step 2.\n\n**Step 1b: Code-level heuristic scan**\n\nRun these greps against the found files. Each maps to a specific heuristic:\n\n```bash\n# H9 — Generic error messages (critical pattern)\ngrep -rn \"error occurred\\|something went wrong\\|invalid input\\|please try again\\|An error\\|Unknown error\" \\\n --include=\"*.tsx\" --include=\"*.jsx\" --include=\"*.vue\" --include=\"*.html\" \\\n --exclude-dir=node_modules --exclude-dir=dist . 2>/dev/null\n\n# H1 — Missing loading states: async handlers without loading flag\ngrep -rn \"onClick\\|onSubmit\\|handleSubmit\" \\\n --include=\"*.tsx\" --include=\"*.jsx\" --exclude-dir=node_modules . 2>/dev/null | head -20\n# (then read those files to check if loading/disabled state is managed)\n\n# H3 — Destructive actions: delete/remove calls without confirmation guard\ngrep -rn \"delete\\|remove\\|destroy\\|clearAll\\|reset\" \\\n --include=\"*.tsx\" --include=\"*.jsx\" -i --exclude-dir=node_modules . 2>/dev/null | \\\n grep -iv \"confirm\\|modal\\|dialog\\|undo\\|trash\\|soft\" | head -20\n\n# H4 — Terminology inconsistency: mixed action words for same concept\ngrep -rn '\"Delete\"\\|\"Remove\"\\|\"Erase\"\\|\"Discard\"\\|\"Clear\"' \\\n --include=\"*.tsx\" --include=\"*.jsx\" --exclude-dir=node_modules . 2>/dev/null\n# Flag if multiple terms coexist in same codebase\n\n# H6 — Icon-only buttons missing accessible label\ngrep -rn \"/dev/null | \\\n grep -v \"aria-label\\|title=\\|children\\|tooltip\" | head -20\n\n# H5 — Forms missing inline validation\ngrep -rn \"/dev/null | head -10\n# (then read those files to check for inline validation vs. submit-only)\n\n# H10 — Empty states: no empty state handling\ngrep -rn \"\\.length === 0\\|\\.length == 0\\|items\\.length\\|data\\.length\" \\\n --include=\"*.tsx\" --include=\"*.jsx\" --exclude-dir=node_modules . 2>/dev/null | \\\n grep -v \"EmptyState\\|empty\\|nothing\\|no items\\|no results\" | head -15\n\n# A11y — Images missing alt text\ngrep -rn \"/dev/null | grep -v \"alt=\" | head -10\n\n# A11y — Buttons missing accessible name (icon-only)\ngrep -rn \"/dev/null | \\\n grep -v \"aria-label\\|aria-labelledby\\|title=\" | head -15\n\n# A11y — onClick on non-interactive elements (no keyboard access)\ngrep -rn \"onClick\" \\\n --include=\"*.tsx\" --include=\"*.jsx\" --exclude-dir=node_modules . 2>/dev/null | \\\n grep -E \"/dev/null | head -10\n\n# A11y — Inputs missing associated label\ngrep -rn \"/dev/null | \\\n grep -v \"type=\\\"hidden\\\"\\|aria-label\\|aria-labelledby\\|id=\" | head -10\n```\n\nFor each grep that returns results: read the flagged files at the relevant lines to confirm whether it's a real violation or a false positive. Report only confirmed violations.\n\n**Step 2: Define scope** — What task(s) is the user trying to complete? What screens/flows are in scope?\n\n**Step 3: Walk the flow** — Step through each screen as a first-time user would. For each screen, check:\n- What is the user trying to do here? (H1: visibility of goal)\n- Can they figure out how to do it? (affordances, signifiers)\n- Will they know when it worked? (feedback, system status)\n- What could go wrong? (error prevention)\n- Is anything adding unnecessary mental work? (cognitive load)\n\n**Step 4: Log violations** — For each violation found (from code scan or conceptual walk):\n```\nFile: [path:line] or Screen: [name]\nHeuristic: [H1–H10, or cognitive load / mental model / affordance]\nViolation: [specific description — quote actual code or UI text where possible]\nSeverity: [1=cosmetic / 2=minor / 3=major / 4=critical]\nFix: [concrete recommendation with code example if applicable]\n```\n\n**Step 5: Report** — Present as a prioritized list, critical issues first. Group by heuristic to surface systemic problems.\n\n**Step 6: Offer next step** — After the report, offer:\n- `fix [H9]` → Generate corrected error messages as a code snippet or new component\n- `generate fix` → Generate redesigned version of worst-offending screen as HTML/TSX\n- `compare` → Side-by-side: current vs. fixed version opened in browser\n- `checklist` → Generate a dev-ready fix checklist (markdown, copy-pasteable to GitHub Issues)\n\n### UX Review Output Format\n\n```\n✦ UX Review: [screen/flow name]\n Scanned: 23 components · 4 violations found\n\n Critical (fix before launch)\n ────────────────────────────\n [H9] src/components/LoginForm.tsx:47\n catch(e) { setError(\"An error occurred\") }\n Fix: setError(`Login failed: ${e.message}. Check your email and password.`)\n\n [H1] src/components/UploadButton.tsx:23\n onClick={handleUpload} — no loading/disabled state managed\n Fix: setLoading(true) on click; disabled={loading}; show inside button\n\n Major (high priority)\n ─────────────────────\n [H3] src/pages/ProjectList.tsx:89\n onClick={() => deleteProject(id)} — no confirmation, immediate delete\n Fix: Move to trash: softDelete(id) + undo toast for 5s, or confirm dialog\n\n Minor (low priority)\n ────────────────────\n [H4] \"Remove\" (src/components/MemberList.tsx:34) vs \"Delete\" (src/pages/Settings.tsx:102)\n Same destructive action, two different words\n Fix: Standardize to \"Remove\" for members, \"Delete\" for owned resources\n\n Summary: 2 critical · 1 major · 1 minor\n Next: fix H9 · fix H1 · generate fix · checklist\n```\n\n### Quick Triggers for UX Review\n\n| User types | Action |\n|---|---|\n| `ux scan` | Code scan only — run all heuristic greps, report file:line violations, no conceptual walk |\n| `ux review` | Full review — code scan + conceptual walk + report |\n| `ux review src/components/` | Scope scan to specific directory |\n| `fix H9` | Generate corrected error message patterns as a code snippet |\n| `fix H1` | Generate loading state pattern for flagged component |\n| `fix H3` | Generate soft-delete / confirmation dialog pattern |\n| `generate fix` | Generate redesigned screen that resolves all critical violations |\n| `checklist` | Output dev-ready markdown checklist of all violations (copy to GitHub Issues) |\n| `compare ux` | Side-by-side: current vs. UX-fixed version in browser |\n\n### Cross-Mode Bridges\n\n**From Site Analysis → UX Review:**\nAfter `audit` extracts tokens and consistency issues, you can continue with `ux scan` — the two modes complement each other. Style audit catches visual/token issues; UX scan catches behavioral/interaction issues.\n\n**From UX Review → Generate:**\nAfter flagging violations, off","tagline":"UX Review mode — heuristic evaluation (Nielsen's 10), cognitive load analysis, mental model diagnosis, affordance audit, dark pattern detection — grounded in NNG research.
