description: Orchestrator for WebView UI mockup workflow - delegates design iteration to ui-design-agent and implementation scaffolding to ui-finalization-agent. Use when user mentions UI design, mockup, WebView interface, or requests 'design UI for [plugin]'.
allowed-tools:
  - Read
  - Task
  - AskUserQuestion
preconditions:
  - None (can work standalone or with creative brief)
<objective> Creates WebView UI mockups for audio plugins through iterative design and implementation scaffolding. </objective>

<quick_start>

  1. •Check for aesthetic library (Phase 0)
  2. •Gather requirements through tiered questions (Phases 1-3)
  3. •Dispatch ui-design-agent for mockup generation
  4. •Iterate until user approves
  5. •Generate implementation files </quick_start>
<workflow> <phase name="A-design-iteration"> <purpose>Generate 2 design files for rapid iteration</purpose> <outputs> - `v[N]-ui.yaml` - Machine-readable design specification - `v[N]-ui-test.html` - Browser-testable mockup </outputs> <gate>Do NOT proceed to Phase B until user approves design via Phase 5.5 decision menu</gate> </phase> <phase name="B-implementation-scaffolding"> <purpose>Generate 5 implementation files ONLY after Phase A approval</purpose> <outputs> - `v[N]-ui.html` - Production HTML - `v[N]-PluginEditor.h` - C++ header boilerplate - `v[N]-PluginEditor.cpp` - C++ implementation boilerplate - `v[N]-CMakeLists.txt` - WebView build configuration - `v[N]-integration-checklist.md` - Implementation steps </outputs> <location>plugins/[PluginName]/.ideas/mockups/</location> </phase> </workflow>

<context_detection> <standalone_mode>

  • •No .continue-here.md file present
  • •Generates mockups independently
  • •Skips state updates </standalone_mode>

<workflow_mode>

  • •File plugins/[PluginName]/.continue-here.md exists with current_stage field
  • •Updates workflow state after each phase </workflow_mode>

Check for .continue-here.md existence to determine mode. If present, update state files. If absent, skip state updates. </context_detection>

<phase name="0-aesthetic-check"> Check if `.claude/aesthetics/manifest.json` exists. If found, count aesthetics using jq. <menu> Found {N} saved aesthetics in library.

How would you like to start the UI design?

  1. •Start from aesthetic template - Apply saved visual system
  2. •Start from scratch - Create custom design
  3. •List all aesthetics - Browse library before deciding

Choose (1-3): _

</menu> <routing> - Option 1: Display aesthetics from manifest with metadata (name, vibe, colors, source). Invoke ui-template-library skill with "apply" operation. Skip to Phase 4 with generated mockup. - Option 2: Continue to Phase 1 (load context). - Option 3: Invoke ui-template-library skill with "list" operation, show previews, return to menu. - No aesthetics: Skip directly to Phase 1. </routing>

See references/aesthetic-integration.md for complete integration details. </phase>

<phase name="1-load-context"> Load context from creative brief and extract requirements. See `references/phase-details.md` for extraction protocol. See `references/context-extraction.md#example-extracting-from-creative-brief` for examples. </phase> <phase name="1.5-context-aware-prompt"> Adapt initial prompt based on creative brief contents (rich/minimal/zero UI details). See `references/phase-details.md` for prompt templates. </phase> <phase name="2-gap-analysis"> Analyze gaps in Tier 1 (Critical), Tier 2 (Visual), Tier 3 (Polish) requirements. See `references/phase-details.md` for tier definitions. See `references/design-questions.md` for question templates. </phase> <phase name="2.5-calculate-dimensions"> Calculate recommended window size before asking user. See `references/phase-details.md` for calculation steps. See `references/layout-validation.md` Section 2 for formulas. </phase> <phase name="3-question-batch"> Generate exactly 4 questions using AskUserQuestion based on identified gaps. See `references/phase-details.md` for rules and question format. See `references/design-questions.md#example-question-batches` for templates. </phase> <phase name="3.5-decision-gate"> Present decision gate with AskUserQuestion: finalize, ask more questions, or add context. Route to Phase 4, back to Phase 2, or collect free-form text. See `references/phase-details.md` for menu format and routing. </phase> <phase name="4-5.45-design-agent"> Invoke ui-design-agent via Task tool to generate YAML + test HTML.

Include in invocation prompt:

  • •All gathered requirements (layout, controls, colors, etc.)
  • •Quality expectation: "Design must look like commercial $50-200 audio plugin - intentional decisions, not defaults"

See references/phase-details.md for invocation summary. See references/delegation-protocols.md for complete protocol. </phase>

<phase name="5.5-design-decision-menu"> <gate>CRITICAL: Phases 6-10 ONLY execute if user chooses option 2 (Finalize)</gate> <menu> Mockup v[N] design created (2 files)

Files generated:

  • •v[N]-ui.yaml (design specification)
  • •v[N]-ui-test.html (browser-testable mockup)

What would you like to do?

  1. •Iterate - Refine design, adjust layout
  2. •Finalize - Validate alignment and complete mockup
  3. •Save as template - Add to aesthetic library for reuse
  4. •Other

Choose (1-4): _

</menu> <routing> - Option 1 (Iterate): Collect refinement feedback, return to Phase 2 with new version (v2, v3, etc.), invoke NEW ui-design-agent instance (fresh context). - Option 2 (Finalize): Proceed to Phase 5.6 (automatic brief update), mockup is source of truth for UI sections, no user interaction needed, continue to Phase 6-10 after brief sync. - Option 3 (Save as template): Invoke ui-template-library skill with "save" operation, after saving return to Phase 5.5 menu. - Option 4 (Other): Handle custom request (test in browser, validate constraints, etc.). </routing>

<iteration_guidance> When collecting feedback for Option 1 (Iterate):

If user provides specific changes ("make it vertical", "add a meter", "change colors to blue"):

  • •Pass these as explicit requirements to new ui-design-agent instance

If user provides vague improvement requests ("make it better", "improve it", "polish it"):

  • •Prompt for specifics: "What aspect should I focus on? (layout, colors, spacing, controls)"
  • •If user says "everything" or "overall quality": Pass instruction to refine existing elements (spacing, color harmony, control styling) rather than add new elements </iteration_guidance>

See references/decision-menus.md#phase-5-5-design-decision-menu for detailed routing. </phase>

<phase name="5.6-update-brief"> Automatic update of creative brief from finalized mockup. Triggered by "Finalize" selection in Phase 5.5. No user interaction required. See `references/phase-details.md` for protocol. </phase> <phase name="6-10-implementation"> <prerequisites> - User confirmed design in Phase 5.5 (selected option 2: Finalize) - Phase A files exist (`v[N]-ui.yaml`, `v[N]-ui-test.html`) - Finalization marker present in YAML </prerequisites>

See references/phase-b-enforcement.md for guard implementation. </phase>

<phase name="6-10.5-finalization-agent"> Invoke ui-finalization-agent via Task tool to generate 5 implementation files. See `references/phase-details.md` for invocation summary. See `references/delegation-protocols.md` for complete protocol. </phase> <phase name="10.7-completion-menu"> Present completion menu after ui-finalization-agent returns successfully. See `references/decision-menus.md#completion-menu` for format and routing. </phase>

<orchestration_protocol> <delegation_rules> This skill NEVER generates mockup files directly. ALL file generation delegated to subagents.

<sequence> 1. Orchestrator: Gather requirements (Phases 0-3.5) 2. Orchestrator: Invoke ui-design-agent via Task tool 3. ui-design-agent: Generate YAML + test HTML, commit, return JSON 4. Orchestrator: Parse JSON, present Phase 5.5 menu 5. If iterate: Orchestrator invokes NEW ui-design-agent 6. If finalize: Orchestrator updates brief (Phase 5.6) 7. Orchestrator: Invoke ui-finalization-agent via Task tool 8. ui-finalization-agent: Generate 5 files, commit, return JSON 9. Orchestrator: Parse JSON, present completion menu </sequence>

See references/delegation-protocols.md for enforcement details. </delegation_rules>

<state_management> Subagents update .continue-here.md with their phase results. Orchestrator verifies stateUpdated flag in JSON report.

After subagent returns stateUpdated: true, verify actual state contents match expected values (not just boolean flag).

Read .continue-here.md, parse YAML, check specific fields match JSON report values. If mismatch, present state recovery menu.

See references/state-tracking.md for complete state schema and verification protocol. </state_management>

<iteration_protocol> Each iteration runs in fresh agent context. User chooses "Iterate" then orchestrator collects feedback and invokes NEW ui-design-agent with incremented version. Fresh context prevents context window bloat during iterative design. </iteration_protocol>

<error_handling>

  • •Agent failures: Present error menu (retry/manual fix/debug/cancel).
  • •Validation failures: Agent returns validationPassed: false - present error menu.
  • •State update failures: Agent returns stateUpdated: false - present state recovery menu (verify/manual update/continue anyway). </error_handling> </orchestration_protocol>

<versioning_strategy> Pattern: v1, v2, v3... Each version saved separately.

Purpose: Explore layouts without losing work, A/B test designs, keep history for rollback.

File naming: All 7 files prefixed with version (e.g., v2-ui.html, v2-PluginEditor.h).

Implementation: Latest version used for Stage 3 (GUI) unless user specifies different version.

See references/versioning.md for file management details. </versioning_strategy>
