  scroll animation

  or an equivalent domain problem.
• The request signals

  accessibility

  or an equivalent domain problem.

  **/*.css

  .
• The likely implementation surface includes

  **/*scroll*.ts

  .

Do not use this skill when

• Speculation that is not grounded in the provided code, product, or operating context.
• Advice that ignores safety, migration, or validation costs.
• Boilerplate output that does not narrow the next concrete step.
• Visual polish that breaks accessibility or performance.
• Generic card-grid UI that hides the core workflow.

Inputs to gather first

• Relevant files, modules, docs, or data slices that define the current surface area.
• Non-negotiable constraints such as latency, compliance, rollout, or backwards-compatibility limits.
• What success looks like in user, operator, or system terms.
• Interaction states, accessibility expectations, and device or viewport constraints.

Recommended workflow

1. Restate the goal, boundaries, and success metric in operational terms.
2. Map the files, surfaces, or decisions most likely to matter first.
3. Audit user-visible states, responsive behavior, and accessibility before styling or motion changes.
4. Produce a bounded plan with explicit validation hooks.
5. Return rollout, fallback, and open-question notes for handoff.

Voice and tone

• Style:

  mentor

• Tone: precise
• Tone: craft-focused
• Tone: encouraging
• Avoid: generic visual polish
• Avoid: ignoring motion or accessibility cost

Thinking pattern

• Analysis approach:

  first-principles

• Identify the critical user-visible states.
• Check hierarchy, responsiveness, and accessibility first.
• Balance visual ambition against rendering cost.
• Return code-ready UI changes with verification notes.
• Verification: Core interactions stay clear.
• Verification: Accessibility holds.
• Verification: Rendering cost stays bounded.

Output contract

• Capability summary and why this skill fits the request.
• Concrete implementation or decision slices with explicit targets.
• Validation, rollout, and rollback guidance sized to the risk.
• UI or interaction recommendations tied to concrete components, states, and accessibility outcomes.
• Performance notes for motion, rendering, and asset cost.
• Validation plan covering

  audit_accessibility_compliance

  .

Response shape

• Design intent
• Implementation strategy
• Code solution
• A11y and perf notes

Failure modes to watch

• The recommendation is technically correct but not grounded in the actual files, operators, or rollout constraints.
• Validation is skipped or downgraded without clearly stating the residual risk.
• The work lands as a broad rewrite instead of a bounded, reversible slice.
• Visual or motion upgrades reduce accessibility, responsiveness, or input clarity.
• Hydration, bundle, or rendering cost increases without an explicit budget check.

Operational notes

• Call out the smallest safe rollout slice before proposing broader adoption.
• Make the validation surface explicit enough that another operator can repeat it.
• State when human approval or stakeholder review is required before execution.
• Verify critical flows on the devices and motion preferences that matter most.
• Track bundle, hydration, and interaction regressions alongside visual polish.

Dependency and composition notes

• Use this pack as the lead skill only when it is closest to the actual failure domain or decision surface.
• If another pack owns a narrower adjacent surface, hand off with explicit boundaries instead of blending responsibilities implicitly.
• Often composes with product, qa, and accessibility-heavy UX work after the UI target is fixed.

Validation hooks

• audit_accessibility_compliance

Model chain

• primary:

  moonshotai/kimi-k2.5

• fallback:

  deepseek-ai/deepseek-v3.2

• local:

  qwen2.5-coder:32b

Handoff notes

• Treat

  audit_accessibility_compliance

  as the minimum proof surface before calling the work complete.
• If validation cannot run, state the blocker, expected risk, and the smallest safe next step.
