+# API Contracts: SpecKit UI Workflow Enhancement
+
+**Feature**: 004-speckit-ui-workflow
+
+## No API Contracts
+
+This feature is a **tooling enhancement** that modifies markdown templates and Claude Code command definitions. It does not expose any programmatic APIs, REST endpoints, GraphQL schemas, or other machine interfaces.
+
+### What This Feature Modifies
+
+| File | Type | Description |
+|------|------|-------------|
+| `.specify/templates/spec-template.md` | Template | Markdown template for feature specifications |
+| `.claude/commands/speckit.specify.md` | Command | Claude Code command definition |
+
+### Why No Contracts
+
+- **No HTTP APIs**: This is not a web service
+- **No CLI interface**: No command-line arguments exposed
+- **No library exports**: No functions/classes for programmatic use
+- **No data exchange**: No structured data formats to document
+
+### Human Interface
+
+The "interface" for this feature is the natural language interaction with Claude Code:
+
+```
+User: /speckit.specify Create a file upload dialog
+Claude: [Generates spec with UI section]
+
+User: /speckit.specify Create a file parser service
+Claude: [Generates spec without UI section]
+```
+
+This interaction is documented in the spec and quickstart, not as a formal API contract.

+# Data Model: SpecKit UI Workflow Enhancement
+
+**Feature**: 004-speckit-ui-workflow
+**Date**: 2026-01-11
+
+## Overview
+
+This feature is a **tooling enhancement** that modifies markdown templates and command definitions. It does not introduce persistent data entities, database tables, or data structures requiring formal modeling.
+
+## Conceptual Entities
+
+While no persistent data is involved, the following conceptual entities are relevant to the implementation:
+
+### Feature Type Classification
+
+```
+FeatureType:
+  - UI_FEATURE (triggers UI section generation)
+  - SERVICE_FEATURE (no UI section)
+  - CLI_FEATURE (no UI section)
+```
+
+**Detection**: Based on keyword presence in feature description text.
+
+### Keyword Lists (Configuration)
+
+```
+UI_KEYWORDS:
+  - dialog, screen, form, wizard, app, window
+  - button, UI, interface, desktop, mobile
+  - panel, modal, picker, selector, dropdown, menu
+
+SERVICE_KEYWORDS:
+  - API, service, backend, parser, processor
+  - handler, worker, queue, batch
+
+CLI_KEYWORDS:
+  - command, terminal, CLI, shell, console
+```
+
+**Usage**: These are embedded in the command definition, not stored as data.
+
+### UI Section Structure
+
+```
+UserInterfaceFlow:
+  - DecisionAnalysis:
+      - primary_goal: string
+      - key_decisions: list[string]
+      - decision_inputs: list[string]
+
+  - ScreenProgression:
+      - rows: list[ProgressionRow]
+        where ProgressionRow:
+          - step: number
+          - screen_state: string
+          - user_action: string
+          - system_response: string
+
+  - UIStates:
+      - empty: string
+      - loading: string
+      - error: string
+      - success: string
+```
+
+**Usage**: This structure guides the markdown generation but is not persisted - it's written directly into spec files.
+
+## Relationships
+
+```
+FeatureDescription --[analyzed by]--> KeywordDetection
+KeywordDetection --[determines]--> FeatureType
+FeatureType --[controls]--> SectionGeneration
+SectionGeneration --[produces]--> UserInterfaceFlow (if UI_FEATURE)
+```
+
+## State Transitions
+
+```
+None applicable - this is a stateless template transformation
+```
+
+## Validation Rules
+
+1. **Keyword matching**: Case-insensitive
+2. **Precedence**: UI keywords override service/CLI keywords
+3. **Default**: SERVICE_FEATURE if no keywords match
+
+## No Persistent Storage
+
+This feature:
+- Does not create database tables
+- Does not modify existing schemas
+- Does not require migrations
+- Does not store user data
+
+All "data" exists transiently during command execution.

+## Validation Checklist Testing (US4)
+
+### UI Feature Specs
+
+When spec contains "User Interface Flow" section, validation includes:
+- [x] Decision Analysis section completed
+- [x] Screen Progression table covers happy path
+- [x] UI States defined for all conditions
+
+### Non-UI Feature Specs
+
+When spec does NOT contain "User Interface Flow" section:

+- [x] Standard validation items still checked
+
+## Files Modified
+
+| File | Changes Verified |
+|------|-----------------|
+| `.specify/templates/spec-template.md` | UI section added with Decision Analysis, Screen Progression, UI States |
+| `.claude/commands/speckit.specify.md` | Detection logic added with keyword lists and precedence rules |
+
+## Conclusion
+
+All 13 test scenarios passed. The enhancement correctly:
+1. Detects UI features by keyword matching
+2. Generates UI section for dialogs, wizards, apps, dashboards
+3. Omits UI section for services, parsers, APIs, CLI tools
+4. Handles hybrid features with correct precedence (UI wins)
+5. Maintains backward compatibility with existing specs
