planifest Responsive Layout Design
Overview
Use this skill to define responsive behavior that keeps critical workflows usable across supported screen sizes.
Scope Boundaries
- Layouts break, overflow, or lose usability across devices.
- Teams need explicit breakpoint and adaptation rules before implementation.
- Localization/content growth increases truncation and wrapping risk.
Templates And Assets
- Responsive rule template:
assets/responsive-rule-template.md
- Breakpoint test checklist:
assets/breakpoint-test-checklist.md
Inputs To Gather
- Device and viewport support matrix.
- Critical tasks and layout priority by context.
- Content constraints including localization expansion risk.
- Interaction modality requirements (touch, pointer, keyboard).
Deliverables
- Responsive rule set with breakpoint-specific behavior.
- Component adaptation guidance for each viewport range.
- Risk list for overflow, truncation, and interaction regressions.
- Verification checklist for critical screens.
Workflow
- Define viewport model and breakpoint rationale.
- Specify component behavior per breakpoint (reflow, collapse, hide, or transform).
- Validate text expansion, dynamic data density, and media constraints.
- Define interaction affordance adjustments by modality.
- Verify critical workflows at each supported viewport range.
- Publish responsive rules with ownership and review cadence.
Quality Standard
- Core tasks remain usable at all supported viewport ranges.
- Overflow and truncation risks are addressed explicitly.
- Interactive targets remain accessible and operable.
- Rules are consistent and do not conflict across breakpoints.
Failure Conditions
- Stop when breakpoint choices lack user/device evidence.
- Stop when critical workflows fail in supported viewport ranges.
- Escalate when responsive constraints conflict with required functionality.
