Changes Made

1. settings.local.json - Stale MCP Permissions Removed

Removed 21 pre-approved permissions for inactive MCP servers:

Removed:

  • 8 Chrome DevTools MCP permissions (mcp__plugin_chrome-devtools-mcp_*)
  • 11 Playwright MCP permissions (mcp__plugin_compound-engineering_playwright_*)
  • 1 unused skill permission (Skill(scientific-skills:get-available-resources))

Retained:

  • Bash(*), WebFetch, WebSearch
  • Active skill permissions: frontend-dev-guidelines, cicd-cross-platform, skill-developer, git:commit, git:commit-and-push

2. settings.json - Unused Plugins Disabled

Removed 11 plugins from awesome-claude-skills that were enabled but unused:

  • file-organizer
  • internal-comms
  • image-enhancer
  • content-research-writer
  • developer-growth-analysis
  • invoice-organizer
  • competitive-ads-extractor
  • lead-research-assistant
  • canvas-design
  • meeting-insights-analyzer
  • mcp-builder

Retained: commit-commands@claude-code-plugins (actively used)

3. skill-rules.json - Overlapping Skills Consolidated

Merged 2 pairs of overlapping skills:

bugfix-planner → bug-detective:

  • Added keywords: bugfix plan, fix plan, reproduce bug, regression, rollback plan
  • Added patterns: (create|make|write).*?(bugfix|fix).*?plan, (plan|strategy).*?(fix|bugfix|repair), root cause.*?(analysis|investigation)

ui-ux-design-expert → frontend-design:

  • Added keywords: UI, UX, user interface, user experience, design review, layout, visual hierarchy, usability, interface design, design system
  • Added patterns: (review|improve|simplify).*?(UI|UX|interface|design|layout), (how|what).*?(design|UX|usability)

Result: 19 skills (was 21)

4. marketplaces.json - Inactive Marketplaces Removed

Removed 3 marketplace registrations that weren’t actively used:

  • claude-code-marketplace (ananddtyagi)
  • fradser-dotagent (FradSer/dotclaude)
  • claude-code-templates (davila7)

Retained: 10 marketplaces including official Anthropic ones

Recommendations for Future Cleanup

  1. Audit remaining marketplaces - Consider removing insforge-official-marketplace and claude-scientific-skills if not actively used
  2. Review skill triggers - Some skills may have overlapping keywords that could be further consolidated
  3. Periodic permission review - Remove MCP permissions when disabling servers
