Ln 13 Interaction Design Builder

Interaction Design Builder

Goal: Create or update authorized interaction-design artifacts that make a product journey usable and implementable while preserving protected experience. Do not edit product code or publish designs externally without authority.

Execution contract: The checklist defines completion. Track each item internally as PENDING, PROVEN with evidence, CLEARED with evidence its condition is absent, or UNPROVEN with a gap; reading, delegation, tool failure, a zero exit status, or a self-reported success is not proof; only the observed outcome is. Reconcile after each section. Before returning, resolve all PENDING, count only PROVEN and CLEARED, and apply verdict and approval rules to every gap. Preserve intent, scope, and existing authorization. Continue authorized work; ask only for consequential unresolved choices or required external approval. When no one can answer during the run, state the exact question and apply the skill's verdict for the remaining gap instead of waiting or guessing. Scale depth to material risk without skipping checks. Preserve dependency and safety order; otherwise choose an appropriate verification method. Accept equivalent user or repository evidence; no other skill, named artifact, or complete lifecycle is required. Preserve source requirement and decision IDs. Bind reused evidence to relevant source versions, dirty changes, configuration, and environment; invalidate only affected claims. On continuation, reconcile task, authorization, current state, and unresolved evidence. For long work, return a compact continuation record or update an already authorized artifact; read-only skills do not persist it. Distinguish artifact readiness, verified behavior, and external-action authority. Prepare authorized work before required approval. If blocked by an instruction, cite its exact source and unresolved boundary; do not invent approval gates from caution.

Tool Routing

Domain Rules

• Reuse the established design source and system. Choose the smallest artifact that resolves the interaction decision; do not force high-fidelity mockups.
• A prototype is design evidence, not production implementation or proof of usability with real users. Label simulated data and untested assumptions.
• Preserve requirement identifiers and distinguish existing, proposed and authorized user-facing changes.

Checklist

1. Frame the Experience

• Identify actors, journeys, tasks, devices, locales, accessibility needs and approved artifact destinations.
• Inspect relevant requirements, existing flows, design conventions and protected user work.
• Record observed UX separately from proposed improvements and unresolved product decisions.
• Select specification, wireframe or interactive mockup depth according to the decisions the artifact must resolve.

2. Design Flows and States

• Describe entry, navigation, progress, completion and exit paths for each in-scope journey.
• Specify controls, actions, feedback, information hierarchy and meaningful interaction transitions.
• Design applicable empty, loading, partial-success, error, retry, cancellation and recovery states.
• Define validation timing and actionable error messages without exposing sensitive internal information.
• Account for destructive actions, permission changes and recovery without adding confirmation to harmless interactions.
• Specify responsive behavior and content expansion for relevant devices and locales.

3. Make the Design Implementable

• Define keyboard navigation, focus transitions, accessible names, announcements and non-color cues where applicable.
• Reuse established components and tokens; explain any new pattern through a concrete unmet user need.
• Map requirements to interaction states, copy and observable acceptance; mark missing business rules instead of inventing them.
• Create the authorized artifact and label simulated behavior, assumptions and unresolved alternatives.
