gabrielmoreira UI/UX Concept Implementation
Overview
Turn a selected visual direction into working UI while preserving the project's product identity and producing browser evidence against the target.
Run this skill in the main conversation. Do not spawn subagents, agent teams, or delegated parallel workers unless the user explicitly approves the proposed count and scope after being told that doing so can increase usage. Ask again before expanding an approved scope.
Establish The Visual Contract
- Confirm that one direction is selected. A single user-supplied mockup, screenshot, or reference site is a selected target. If materially different concepts remain unselected, return to the coordinator or obtain the user's selection before implementation.
- If the selected target is an operational dashboard and a dashboard-specific workflow is available, return to the coordinator and use it. Otherwise continue with this general visual-reference workflow.
- Inspect the target and the current rendered UI at the relevant routes, viewports, themes, data states, and interaction states. Ask a narrow question only when unresolved ambiguity would produce materially different results.
- Classify the target's visible decisions as exact (must match), adaptable (translate into the product's visual language), or unspecified (follow established project conventions). Record only the distinctions needed to guide implementation and verification.
- Treat existing project instructions, design-system sources, components, tokens, content, assets, responsive conventions, and accessibility patterns as constraints. Do not replace suitable project identity merely because the reference uses a different system.
- Preserve the selected concept outside committed source only when later comparison genuinely needs a durable artifact. Prefer an existing ignored or environment-managed location; do not create project files or modify ignore configuration solely for transient persistence without authorization.
Implement The Direction
- Map the visual contract to project-owned routes, components, styles, tokens, assets, and representative content. Reuse existing surfaces when their semantics fit; introduce new ones only for a concrete gap.
- Recreate the target's structure, hierarchy, rhythm, responsive intent, and interactions without copying proprietary source, private assets, tracking code, or brand-identifying content that the user is not authorized to use.
- Preserve product behavior and accessible semantics while adapting visual details. Cover only the loading, empty, error, validation, focus, or other states that the affected surface can meaningfully enter.
- Add a dependency only when project tools cannot reasonably satisfy a material part of the visual contract and the tradeoff is clear.
Compare In A Real Rendering Environment
- Follow the host and project browser-testing policy instead of assuming one universal tool. Capture the smallest useful region, using full-page images only when composition, scrolling, or surrounding context matters.
- Compare the target, before state, and updated state at equivalent viewports, theme, data, account, and interaction state when practical. Disclose any mismatch in comparison conditions.
- Iterate on material differences in layout, hierarchy, spacing, typography, color, imagery, overflow, text fit, and interaction. Stop when the visual contract is satisfied or when a concrete blocker requires user direction.
- Verify relevant responsive behavior, keyboard-visible focus, and interaction states. Keep exploratory browser evidence distinct from source-controlled automated E2E coverage.
- If no real rendering environment is available, perform the closest useful source-level check, report the gap, and do not claim visual fidelity.
Final Handoff
Report:
- The selected target and any important exact-versus-adaptable decisions.
- Files changed.
- Browser verification performed, including evidence paths when available.
- Remaining visual mismatches, unverified states or viewports, and comparison limitations.
- The location and uncommitted status of any temporary concept artifact, only when one was actually created.
