[IMPORTANT] Use

TaskCreate
to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

<!-- SYNC:critical-thinking-mindset -->

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

<!-- /SYNC:critical-thinking-mindset --> <!-- SYNC:ai-mistake-prevention -->

AI Mistake Prevention — Failure modes to avoid on every task:

  • Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal.
  • Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing.
  • Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain.
  • Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path.
  • When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site.
  • Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code.
  • Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks.
  • Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis.
  • Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly.
  • Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

Quick Summary

Goal: Assist UX Designers with design specs, component docs, accessibility audits, and dev handoffs.

Workflow:

  1. Design Spec — Generate component specs from PBI with tokens, states, responsive behavior
  2. Component Doc — Document states, variants, interactions, BEM classes, ARIA
  3. Accessibility Audit — WCAG 2.1 AA checklist with issue tracking and remediation
  4. Design Handoff — Developer-ready specs with assets, animations, and source links

Key Rules:

  • All components must map to BEM class naming
  • Design tokens only (no hardcoded values)
  • All 7 states documented (default, hover, active, focus, disabled, error, loading)

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Workflow Integration

Creating Design Spec from PBI

When user runs

/design-spec {pbi-file}
:

  1. Read PBI and acceptance criteria
  2. Identify UI components needed
  3. Generate component specifications
  4. Document design tokens
  5. Add accessibility requirements
  6. Save to
    team-artifacts/design-specs/

Accessibility Audit

When user says "accessibility audit":

  1. Identify feature/component to audit
  2. Apply WCAG 2.1 AA checklist
  3. Document issues found
  4. Suggest remediations
  5. Generate audit report

Accessibility Audit Template

.user-card {
    &__avatar {
    }

    }
    &__actions {
        &.--collapsed {
        }
    }
