## Request Details

**Requestor:** Human (project owner)
**Date Received:** 02-15-2026
**Priority:** High

## Description

Extend the `save_uiux_reference` MCP tool and Flask endpoint to accept richer reference data and automatically generate structured output files. This CR documents the schema extension and structured folder output that was already implemented in TASK-454.

Changes:
1. **Extended element data schema**: Elements can now include `html_css` (outer_html, computed_styles) for component HTML/CSS extraction
2. **Static resources tracking**: New optional `static_resources` field (list of {type, src, usage}) for fonts, icons, and images
3. **Structured folder output**: When elements contain `html_css` data, the service auto-generates:
   - `page-element-references/resources/{id}-structure.html`
   - `page-element-references/resources/{id}-styles.css`
   - `page-element-references/summarized-uiux-reference.md`
   - `mimic-strategy.md` (6-dimension validation rubric)

## Business Justification

- Current save only produces flat JSON session files — insufficient for agent-driven mockup generation
- Structured output (HTML/CSS snippets, summarized reference, mimic strategy) enables the agent to produce more accurate mockups
- Static resource tracking ensures fonts/icons/images are captured for 99% visual fidelity

## Impact Analysis

### Classification

**Type:** Modification to FEATURE-033

**Reasoning:**
The changes extend the existing `save_uiux_reference` tool with additional optional fields and auto-generated output files. Same API endpoint, same users, same tool name. Backward compatible — v1.0 payloads work unchanged.

### Comparison Matrix

| Aspect | CR Requirement | Existing Feature |
|--------|---------------|------------------|
| Users | CLI agents (same) | CLI agents |
| Workflow | Same: agent calls MCP tool → Flask saves data | Same |
| Data Model | Extended: html_css, static_resources, structured output | Flat JSON session + merged reference-data.json |
| UI Elements | None | None |
| API Endpoints | Same endpoint, extended payload | POST /api/ideas/uiux-reference |

### Affected Components

| Component | Impact Level | Details |
|-----------|--------------|---------|
| uiux_reference_service.py | High | 4 new methods for structured output (already implemented) |
| app_agent_interaction.py | Low | Updated tool docstring (already done) |
| test_uiux_reference.py | Medium | 17 new tests added (already passing) |

### Dependencies

- None — changes are backward compatible

## Proposed Approach

Update FEATURE-033 specification to document the extended schema and structured output capabilities. All code changes are already implemented and tested (TASK-454, 60 tests pass).

## Mockup Impact
