✨ PR Description

Purpose: Add Neo4j-based skill framework management with hierarchical competency navigation to replace hardcoded skill categories in LearnCard App.

Main changes:

• Implemented complete skill framework CRUD operations with Neo4j backend including framework creation, skill tree management, and admin/network associations
• Added framework-based skill selector with multi-column browsing interface replacing legacy hardcoded BoostCMSSkillsAttachmentForm component in boost creation flows
• Integrated Open Badges v3 alignment types with automatic icon generation and hierarchical skill/tier distinction for credential attachments

✨ PR Review

This is a substantial PR that introduces skill frameworks and redesigns the Skills Hub. The code is generally well-structured with proper type definitions and helper functions. However, there's a critical error handling issue in the alignment extraction logic that could cause runtime failures when processing credentials with malformed URLs.

1 issues detected:

🐞 Bug - Missing error handling for decodeURIComponent which can throw URIError on malformed input

Details: The decodeURIComponent calls on lines 93-94 can throw URIError exceptions if the URL contains malformed percent-encoding sequences. This could crash the extractSkillIdsFromAlignments function when processing credentials from external sources or with corrupted alignment data, preventing skills from being extracted and potentially breaking the entire skill management flow.

Full PR Review & Merge Recommendation

I've conducted a comprehensive review of this large PR that introduces skill frameworks management to LearnCard App. Here's my detailed analysis and recommendation.

🔍 Technical Review Summary

This PR successfully brings the skill frameworks system from Scouts to LCA, introducing comprehensive framework management with Neo4j integration and OpenBadges v3 alignment support.

✅ Strengths

Architecture & Implementation

• Well-structured skill framework system with clear separation between legacy skills and new framework-based alignments
• Proper TypeScript integration with strong type definitions (SkillFramework, SkillFrameworkNode, BoostCMSAlignment)
• Comprehensive CRUD operations for frameworks with JSON import/export functionality
• Smart dual-mode operation maintaining backward compatibility with existing hardcoded skills while introducing dynamic frameworks

Code Quality

• Clean component architecture with logical separation of concerns across 57+ new components
• Consistent naming conventions and proper React patterns throughout
• Proper state management using React hooks and query invalidation
• Good abstraction layers between API models and UI models with conversion helpers

User Experience

• Intuitive Skills Hub redesign with filtering, searching, and sorting capabilities
• Seamless framework browsing with hierarchical skill navigation
• Admin panel integration with appropriate role-based access controls
• Framework management UI for creation, editing, and skill management

⚠️ Critical Issues

1. Error Handling Vulnerability (High Priority)

Location: alignmentHelpers.ts:93-94

if (!frameworkId) frameworkId = decodeURIComponent(urlMatch[1]);
if (!skillId) skillId = decodeURIComponent(urlMatch[2]);

Issue: decodeURIComponent() can throw URIError on malformed URLs, causing runtime failures when processing credentials with corrupted alignment data.

Impact: Could crash the skill extraction process and break the entire Skills Hub functionality.

Fix: Add try-catch blocks around decodeURIComponent() calls.

2. Missing Changeset (Blocking)

The PR lacks a changeset for version management, which will prevent proper version bumping and release notes.

3. Failed Deploy

Staging deployment failed - needs investigation before merge.

🔧 Minor Issues

Code Quality

• Some overly long files (BrowseFrameworkPage.tsx at 1000+ lines) could benefit from further componentization
• Missing error boundaries in some new modal components
• Some hardcoded strings that could be extracted to constants

Testing

• Limited test coverage for new framework functionality
• No integration tests for Neo4j skill operations
• Missing tests for alignment extraction logic

📊 Breaking Changes Assessment

✅ No Breaking Changes Detected

• Maintains backward compatibility with existing skills system
• New framework features are additive
• Legacy skill display components preserved
• API changes are non-breaking extensions

🔒 Security Assessment

✅ Generally Secure

• No introduction of new authentication endpoints
• Proper input validation in framework creation
• Role-based access controls implemented correctly
• No sensitive data exposure in new components

⚠️ URL Parsing Vulnerability
The decodeURIComponent issue mentioned above could potentially be exploited with malformed URLs.

📋 Merge Readiness Checklist

Blockers 🚫

• Critical: Fix decodeURIComponent error handling in alignmentHelpers.ts
• Critical: Add missing changeset for version management
• Major: Resolve staging deployment failure

Recommended Before Merge ⚠️

• Add error boundaries to new modal components
• Extract hardcoded strings to constants
• Add basic integration tests for framework CRUD operations
• Consider splitting large components (BrowseFrameworkPage.tsx)

Post-Merge Improvements 📝

• Add comprehensive test coverage for alignment extraction
• Performance optimization for large framework datasets
• Enhanced error messaging for framework operations
• Consider implementing caching for frequently accessed frameworks

🎯 Final Recommendation

CONDITIONAL APPROVE ⚠️

This is a high-quality implementation that successfully brings skill frameworks to LCA with excellent architecture and user experience. However, three critical blockers must be resolved before merging:

1. Fix the decodeURIComponent error handling - This could cause runtime crashes
2. Add the missing changeset - Required for proper version management
3. Resolve staging deployment failure - Needs investigation

Once these blockers are addressed, this PR will be ready for merge. The implementation is solid, maintains backward compatibility, and provides significant value to the LCA ecosystem.

🏆 Code Quality Rating: 8.5/10

• Strong architecture and implementation ✅
• Excellent type safety and React patterns ✅
• Good user experience design ✅
• Critical error handling issue ❌
• Missing deployment configuration ❌

---

Review Tasks

• Analyze core skill framework implementation
• Review new UI components and integration
• Check error handling and security
• Assess code quality and architecture
• Evaluate merge readiness
• Provide final recommendation

@smurflo2 Although the loom isn't working, I was able to go through and make a framework and skills and test basic CRUD stuff. Everything looks to be stable to me and no major issues. I have a few thoughts on some things that are more for UI/UX discussion but don't need to be addressed at the moment:

• This "Review & Edit Framework" button doesn't do anything atm but seems like it should.

• For UI/UX discussion: This is abit confusing to me, there is "Edit Framework" in the dot menu and "Edit Framework" in the header of the page up top but they do different things:

The "Edit Framework" found in the dot menu on the framework list item on the left opens this:

The "Edit Framework" up top opens this edit mode where you can add/edit skills/tiers:

I think they should not be called the same thing since they don't open the same editing modes.

• I think it's weird that the emoji picker and the emoji displayed are different styles (one is the iOS emoji style/one is the windows style flat emoji):
  In the picker:

In the display after selected:
