Skill Manager

Analyze skill inventory, detect duplicates, and clean up safely across multiple AI coding tools.

When to Use

Use this skill when user wants to:

• Analyze their skill collection
• Find and remove duplicate skills
• Backup skills before cleanup
• List all installed skills

Example Workflow

Example 1: Analyzing Skills

user: "Analyze my skills"
→ Detect installed tools (Claude Code, OpenCode, etc.)
→ Run: bash scripts/analyze-interactive.sh
→ Show skill count per tool
→ Identify duplicate categories
→ Suggest: "Keep agent-builder, remove skill-creator"

Example 2: Cleaning Up Duplicates

user: "Clean up my duplicate skills"
→ Review references/categories.md
→ Show duplicate table:
  Category: Agent Creation
  - Keep: agent-builder
  - Remove: agent-identifier, skill-creator, skill-writer
→ Confirm: "Remove these 3 skills?"
→ Run backup first
→ Execute: npx skills remove -g agent-identifier skill-creator skill-writer

Example 3: Listing Skills

user: "List all my skills"
→ Detect tool: "Found Claude Code at ~/.claude/skills/"
→ List skills by category:
  Agent: agent-builder, planner
  Debug: debugging, test-driven-development
  Web: react-best-practices, web-frameworks

Commands

Analyze

bash scripts/analyze-interactive.sh

Shows:

• Total skill count per tool
• Duplicate categories
• Removal recommendations

List

bash scripts/skill-manager-cli list

Backup

bash scripts/skill-manager-cli backup

Saves to: ~/.skill-manager/backups/YYYYMMDD_HHMMSS/

Duplicate Categories

Check these groups (see references/categories.md):

Agent Creation – Keep agent-builder, remove others Planning – Keep planner + subagent-driven-development Debugging – Keep debugging MCP – Keep mcp-builder + mcp-management Frontend – Keep react-best-practices + web-frameworks

Safety Checklist

Before removing:

• Run backup: bash scripts/skill-manager-cli backup
• Review references/categories.md
• Verify: npx skills remove -g [skill-name]
• Test after each batch

Detected Tools

Auto-detects:

• ~/.claude/skills/ (Claude Code)
• ~/.config/opencode/skills/ (OpenCode)
• ~/.cursor/skills/ (Cursor)
• ~/.copilot/skills/ (GitHub Copilot)

Output

Generates:

• Skill inventory table
• Category breakdown
• Duplicate comparison
• Safe removal commands
