+# UI5 Modernization Plugin
+
+A comprehensive plugin providing a complete toolkit for modernizing SAPUI5/OpenUI5 applications by removing deprecated APIs and producing modernized UI5 code.
+
+## Overview
+
+Modernized UI5 code removes all deprecated APIs and global namespace access. This plugin provides:
+
+- **Autonomous migration workflow** with end-to-end orchestration
+- **Specialized fix skills** for every linter rule category
+- **Validation** at every step via UI5 linter integration
+
+## Skills Included
+
+This plugin bundles 14 specialized skills for producing modernized UI5 code:
+
+### Migration Workflow
+
+- **`/modernize-ui5`** - Autonomous end-to-end workflow: runs linter, applies autofix, uses specialized skills for remaining errors, documents unfixable issues, and generates a summary report
+
+### Global Namespace Fixes
+
+- **`/fix-js-globals`** - Fix JavaScript `no-globals` errors: global namespace assignments, delete expressions, `sap.ui.core.Core` direct access, jQuery/$ global calls
+- **`/fix-xml-globals`** - Fix XML view/fragment globals: global variable access, ambiguous event handlers, formatters, type references in bindings, factory functions, legacy `template:require` syntax
+- **`/fix-pseudo-modules`** - Fix pseudo module and implicit global issues: deprecated enum/DataType pseudo module access, direct `library.EnumName` access, OData expression addons in bindings
+
+### Deprecated API Fixes
+
+- **`/fix-deprecated-controls`** - Fix deprecated controls, classes, interfaces, and types with modern replacements (e.g., `sap.m.MessagePage` to `IllustratedMessage`)
+- **`/fix-partially-deprecated-apis`** - Fix partially deprecated API usage: `Parameters.get`, `JSONModel.loadData`, `Mobile.init`, `ODataModel.v2.createEntry`, `View.create`, `Fragment.load`, `Router` constructor, string formatters in JS bindings
+- **`/fix-table-row-mode`** - Migrate deprecated Table row properties (`visibleRowCountMode`, `visibleRowCount`, `rowHeight`, `fixedRowCount`, `fixedBottomRowCount`, `minAutoRowCount`) to structured `rowMode` aggregation
+
+### Component and Bootstrap Fixes
+
+- **`/fix-component-async`** - Fix Component.js async configuration: `IAsyncContentCreation` interface, manifest declaration, redundant async flags
+- **`/fix-bootstrap-params`** - Fix HTML bootstrap parameter issues: missing/deprecated parameters (`async`, `compat-version`, `animation`, `binding-syntax`), deprecated theme values, deprecated libraries
+- **`/fix-manifest-json`** - Fix manifest.json issues: outdated manifest version, legacy UI5 version, deprecated libraries/components, deprecated view/model types, removed properties
+
+### Control and Rendering Fixes
+
+- **`/fix-control-renderer`** - Fix Control renderer issues: missing renderer declaration, string-based renderer, implicit auto-discovery (breaking change in modernized UI5 code), `apiVersion:2` configuration
+- **`/fix-csp-compliance`** - Fix Content Security Policy compliance: unsafe inline scripts, inline JavaScript in HTML, inline event handlers
+- **`/fix-xml-native-html`** - Fix native HTML and SVG usage in XML views/fragments: replace `html:div`, `html:span`, `html:a` with UI5 controls, SVG with UI5 icons
+
+### Test Infrastructure
+
+- **`/fix-test-starter`** - Migrate from legacy QUnit test setup to modern Test Starter concept for `*.qunit.html` and `*.qunit.js` files
+
+## Quick Start
+
+### 1. Start with the Migration Workflow
+
+The main entry point is the autonomous workflow skill which orchestrates the entire migration:
+
+```
+/modernize-ui5
+```
+
+This will autonomously:
+- Run UI5 linter to assess the current state
+- Apply autofix for issues the linter can resolve
+- Use specialized skills for remaining errors
+- Document unfixable issues
+- Generate a summary report
+
+### 2. Use Specialized Skills for Specific Issues
+
+When you encounter specific error patterns, use the targeted skills:
+
+```
+# Global namespace issues
+/fix-js-globals                   # For no-globals errors in JS files
+/fix-xml-globals                  # For no-globals errors in XML views/fragments
+/fix-pseudo-modules               # For pseudo module and implicit global issues
+
+# Deprecated API migrations
+/fix-deprecated-controls          # For deprecated controls, classes, interfaces
+/fix-partially-deprecated-apis    # For partially deprecated API calls
+/fix-table-row-mode               # For deprecated Table row properties
+
+# Component and bootstrap
+/fix-component-async              # For Component.js async issues
+/fix-bootstrap-params             # For HTML bootstrap parameters
+/fix-manifest-json                # For manifest.json issues
+
+# Control and rendering
+/fix-control-renderer             # For control renderer issues
+/fix-csp-compliance               # For CSP compliance issues
+/fix-xml-native-html              # For native HTML/SVG in XML views
+
+# Test infrastructure
+/fix-test-starter                 # For Test Starter migration
+```
+
+## Understanding Modernized UI5 Code Requirements
+
+### Critical Success Criteria
+
+For your app to produce modernized UI5 code, you MUST fix **ALL linter errors (severity 2)** reported by the UI5 linter:
+
+**Common error categories:**
+1. **`no-deprecated-api`** - All deprecated APIs that must be replaced (most common)
+2. **`no-globals`** - All global namespace access must use proper imports (most common)
+3. **Other rule violations** - Any additional errors specific to your codebase
+
+**Check your progress:**
+```bash
+# Count ALL critical errors (must be 0)
+npx @ui5/linter --format json 2>&1 | jq '[.[] | select(.messages) | .messages[] | select(.severity == 2)] | length'
+
+# Count by specific categories (for tracking progress)
+npx @ui5/linter --format json 2>&1 | jq '[.[] | select(.messages) | .messages[] | select(.severity == 2)] | group_by(.ruleId) | map({rule: .[0].ruleId, count: length})'
+```
+
+### Error vs Warning Priority
+
+- **Errors (severity 2)** 🔴 - MUST fix ALL for modernized UI5 code
+- **Warnings (severity 1)** ⚠️ - Can address later (non-blocking)
+
+The migration workflow focuses on `no-globals` and `no-deprecated-api` as these are the most common error categories, but you must address ALL errors to achieve fully modernized UI5 code.
+
+## Migration Phases Overview
+
+The `/modernize-ui5` workflow handles the following phases autonomously:
+
+```
+Phase 1: Assessment
+├── Run linter baseline
+├── Count all critical errors (severity 2)
+└── Create migration branch
+
+Phase 2: Autofix
+├── Run linter with --fix flag
+└── Review and validate autofix changes
+
+Phase 3: Fix Remaining Errors
+├── Apply specialized skills per linter rule
+├── Track progress continuously
+└── Document unfixable issues
+
+Phase 4: Validation and Completion
+├── Run final linter check (0 errors required)
+├── Build verification
+└── Generate migration summary report
+```
+
+## Key Features
+
+### Autonomous Execution
+
+The `/modernize-ui5` workflow is designed for **autonomous execution**:
+
+1. Runs the full migration end-to-end without constant confirmation
+2. Applies autofix first, then uses specialized skills for remaining errors
+3. Tracks progress via continuous linter error counts
+4. Documents unfixable issues separately
+5. Generates a comprehensive summary report
+
+### Validation Tools
+
+Built-in validation at every step:
+
+- **Linter integration** - Continuous error count tracking
+- **Build verification** - Confirms no breaking changes
+- **Detailed guidance** - UI5 Linter `--details` flag for immediate fix guidance
+- **UI5 MCP Server** - API documentation and replacements
+
+## Prerequisites
+
+Before using this plugin, ensure you have:
+
+1. **UI5 application** on version 1.71+ (preferably 1.120+)
+2. **UI5 linter installed**: `npm install --save-dev @ui5/linter`
+3. **Git repository** with clean working directory
+4. **Test suite** working (QUnit/OUnit/OPA)
+5. **Build system** working (UI5 CLI or Maven)
+
+## Expected Results
+
+### Before Migration
+
+- no-deprecated-api errors: 200-500+ ❌
+- no-globals errors: 100-300+ ❌
+- Build: ✅ Success
+- Tests: ✅ Passing
+
+### After Migration (Modernized UI5 Code)
+
+- **ALL LINTER ERRORS: 0** ✅ (REQUIRED - any severity 2 error means code is not fully modernized)
+  - no-deprecated-api errors: 0 ✅
+  - no-globals errors: 0 ✅
+  - Other rule errors: 0 ✅
+- Linter warnings: <100 ⚠️ (acceptable)
+- Build: ✅ Success
+- Tests: ✅ Passing
+
+## Estimated Timeline
+
+For a large enterprise application (300+ JS files):
+
+- **Phase 0 (Assessment)**: 1 day
+- **Phase 1-5 (Critical Errors)**: 16-27 days
+- **Phase 6-7 (Supporting)**: 2 days
+- **Phase 8-10 (Validation)**: 5-7 days
+- **Total**: 24-40 days
+
+Smaller applications will take proportionally less time.
+
