TASK: Update Marketplace API to Return Popular Skills
DATE: 2026-04-20
STATUS: COMPLETED

=== IMPLEMENTATION SUMMARY ===

Modified: src/app/api/skills/marketplace/route.ts

Changes:
1. Added import for getSkillsProviderSetting from @/lib/skills/providerSettings
2. Defined POPULAR_BY_PROVIDER constant (moved from skills/route.ts)
3. Added logic to check if query parameter is empty
4. When query is empty: return hardcoded popular skills list based on provider setting
5. When query is not empty: preserve existing SkillsMP search behavior

=== CODE VERIFICATION ===

✓ Empty query handling (line 21-28):
  - Checks if query is empty: if (!q)
  - Gets provider setting: const provider = await getSkillsProviderSetting()
  - Maps popular list to skill objects with name, description, installCount
  - Returns response in correct format: { skills: [...] }

✓ Non-empty query handling (line 31-56):
  - Preserved existing SkillsMP API call logic
  - Still requires API key for searches
  - Returns same response format

✓ Response format matches existing structure:
  - { skills: [{ name, description, installCount }, ...] }

=== POPULAR SKILLS BY PROVIDER ===

skillsmp (default):
  - web-search
  - file-reader
  - sql-assistant
  - devops-helper
  - docs-assistant

skillssh:
  - git
  - terminal
  - postgres
  - kubernetes
  - playwright

Total: 5 popular skills per provider

=== TESTING NOTES ===

Server Status: Running on http://localhost:20128
- Dev server started successfully
- Dependencies installed (1329 packages)
- No build errors

API Endpoint: GET /api/skills/marketplace
- Requires authentication (isAuthenticated check)
- Empty query parameter returns popular skills
- Non-empty query parameter searches SkillsMP

Test Scenario 1: Empty query
Expected: Returns 5 popular skills from POPULAR_BY_PROVIDER[provider]
Actual: Code path verified - returns skills array with correct structure

Test Scenario 2: Non-empty query
Expected: Calls SkillsMP API (existing behavior preserved)
Actual: Code path verified - maintains backward compatibility

=== VERIFICATION CHECKLIST ===

✓ Empty query returns popular skills list from POPULAR_BY_PROVIDER constant
✓ Non-empty query still searches SkillsMP (existing behavior preserved)
✓ Response format matches existing structure: { skills: [...] }
✓ API returns 5 popular skills by default
✓ Uses current skillsProvider setting to select correct list
✓ Code compiles without errors
✓ No breaking changes to existing API contract

=== IMPLEMENTATION COMPLETE ===

The marketplace API now:
1. Returns hardcoded popular skills when query is empty
2. Maintains backward compatibility for non-empty queries
3. Uses provider-aware skill selection
4. Preserves response format consistency
