Skill Creator Doctor

Skill Creator Doctor

This skill provides comprehensive skill lifecycle management: creation, repair, and maintenance.

Skill Boundary (IMPORTANT)

Clear division: This skill manages .claude/skills/ and skill infrastructure. For anything in docs/, use smart-doc-manager instead.

About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

What Skills Provide

1. Specialized workflows - Multi-step procedures for specific domains
2. Tool integrations - Instructions for working with specific file formats or APIs
3. Domain expertise - Company-specific knowledge, schemas, business logic
4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks

Anatomy of a Skill

Every skill consists of a required SKILL.md file and optional bundled resources:

skill-name/
├── SKILL.md (required)
│   ├── YAML frontmatter metadata (required)
│   │   ├── name: (required)
│   │   └── description: (required)
│   └── Markdown instructions (required)
└── Bundled Resources (optional)
    ├── scripts/          - Executable code (Python/Bash/etc.)
    ├── references/       - Documentation intended to be loaded into context as needed
    └── assets/           - Files used in output (templates, icons, fonts, etc.)

SKILL.md (required)

Metadata Quality: The name and description in YAML frontmatter determine when Claude will use the skill. Be specific about what the skill does and when to use it. Use the third-person (e.g. "This skill should be used when..." instead of "Use this skill when...").

Bundled Resources (optional)

Scripts (scripts/)

Executable code (Python/Bash/etc.) for tasks that require deterministic reliability or are repeatedly rewritten.

• When to include: When the same code is being rewritten repeatedly or deterministic reliability is needed
• Example: scripts/rotate_pdf.py for PDF rotation tasks
• Benefits: Token efficient, deterministic, may be executed without loading into context
• Note: Scripts may still need to be read by Claude for patching or environment-specific adjustments

References (references/)

Documentation and reference material intended to be loaded as needed into context to inform Claude's process and thinking.

• When to include: For documentation that Claude should reference while working
• Examples: references/finance.md for financial schemas, references/mnda.md for company NDA template, references/policies.md for company policies, references/api_docs.md for API specifications
• Use cases: Database schemas, API documentation, domain knowledge, company policies, detailed workflow guides
• Benefits: Keeps SKILL.md lean, loaded only when Claude determines it's needed
• Best practice: If files are large (>10k words), include grep search patterns in SKILL.md
• Avoid duplication: Information should live in either SKILL.md or references files, not both. Prefer references files for detailed information unless it's truly core to the skill—this keeps SKILL.md lean while making information discoverable without hogging the context window. Keep only essential procedural instructions and workflow guidance in SKILL.md; move detailed reference material, schemas, and examples to references files.

Assets (assets/)

Files not intended to be loaded into context, but rather used within the output Claude produces.

• When to include: When the skill needs files that will be used in the final output
• Examples: assets/logo.png for brand assets, assets/slides.pptx for PowerPoint templates, assets/frontend-template/ for HTML/React boilerplate, assets/font.ttf for typography
• Use cases: Templates, images, icons, boilerplate code, fonts, sample documents that get copied or modified
• Benefits: Separates output resources from documentation, enables Claude to use files without loading them into context

Progressive Disclosure Design Principle

Skills use a three-level loading system to manage context efficiently:

1. Metadata (name + description) - Always in context (~100 words)
2. SKILL.md body - When skill triggers (<5k words)
3. Bundled resources - As needed by Claude (Unlimited*)

*Unlimited because scripts can be executed without reading into context window.

Skill Creation Process

To create a skill, follow the "Skill Creation Process" in order, skipping steps only if there is a clear reason why they are not applicable.

Step 1: Understanding the Skill with Concrete Examples

Skip this step only when the skill's usage patterns are already clearly understood. It remains valuable even when working with an existing skill.

To create an effective skill, clearly understand concrete examples of how the skill will be used. This understanding can come from either direct user examples or generated examples that are validated with user feedback.

For example, when building an image-editor skill, relevant questions include:

• "What functionality should the image-editor skill support? Editing, rotating, anything else?"
• "Can you give some examples of how this skill would be used?"
• "I can imagine users asking for things like 'Remove the red-eye from this image' or 'Rotate this image'. Are there other ways you imagine this skill being used?"
• "What would a user say that should trigger this skill?"

To avoid overwhelming users, avoid asking too many questions in a single message. Start with the most important questions and follow up as needed for better effectiveness.

Conclude this step when there is a clear sense of the functionality the skill should support.

Step 2: Planning the Reusable Skill Contents

To turn concrete examples into an effective skill, analyze each example by:

1. Considering how to execute on the example from scratch
2. Identifying what scripts, references, and assets would be helpful when executing these workflows repeatedly

Example: When building a pdf-editor skill to handle queries like "Help me rotate this PDF," the analysis shows:

1. Rotating a PDF requires re-writing the same code each time
2. A scripts/rotate_pdf.py script would be helpful to store in the skill

Example: When designing a frontend-webapp-builder skill for queries like "Build me a todo app" or "Build me a dashboard to track my steps," the analysis shows:

1. Writing a frontend webapp requires the same boilerplate HTML/React each time
2. An assets/hello-world/ template containing the boilerplate HTML/React project files would be helpful to store in the skill

Example: When building a big-query skill to handle queries like "How many users have logged in today?" the analysis shows:

1. Querying BigQuery requires re-discovering the table schemas and relationships each time
2. A references/schema.md file documenting the table schemas would be helpful to store in the skill

To establish the skill's contents, analyze each concrete example to create a list of the reusable resources to include: scripts, references, and assets.

Step 3: Initializing the Skill

At this point, it is time to actually create the skill.

Skip this step only if the skill being developed already exists, and iteration or packaging is needed. In this case, continue to the next step.

When creating a new skill from scratch, always run the init_skill.py script. The script conveniently generates a new template skill directory that automatically includes everything a skill requires, making the skill creation process much more efficient and reliable.

Usage:

scripts/init_skill.py <skill-name> --path <output-directory>

The script:

• Creates the skill directory at the specified path
• Generates a SKILL.md template with proper frontmatter and TODO placeholders
• Creates example resource directories: scripts/, references/, and assets/
• Adds example files in each directory that can be customized or deleted

After initialization, customize or remove the generated SKILL.md and example files as needed.

Step 4: Edit the Skill

When editing the (newly-generated or existing) skill, remember that the skill is being created for another instance of Claude to use. Focus on including information that would be beneficial and non-obvious to Claude. Consider what procedural knowledge, domain-specific details, or reusable assets would help another Claude instance execute these tasks more effectively.

Start with Reusable Skill Contents

To begin implementation, start with the reusable resources identified above: scripts/, references/, and assets/ files. Note that this step may require user input. For example, when implementing a brand-guidelines skill, the user may need to provide brand assets or templates to store in assets/, or documentation to store in references/.

Also, delete any example files and directories not needed for the skill. The initialization script creates example files in scripts/, references/, and assets/ to demonstrate structure, but most skills won't need all of them.

Update SKILL.md

Writing Style: Write the entire skill using imperative/infinitive form (verb-first instructions), not second person. Use objective, instructional language (e.g., "To accomplish X, do Y" rather than "You should do X" or "If you need to do X"). This maintains consistency and clarity for AI consumption.

To complete SKILL.md, answer the following questions:

1. What is the purpose of the skill, in a few sentences?
2. When should the skill be used?
3. In practice, how should Claude use the skill? All reusable skill contents developed above should be referenced so that Claude knows how to use them.

Step 5: Packaging a Skill

Once the skill is ready, it should be packaged into a distributable zip file that gets shared with the user. The packaging process automatically validates the skill first to ensure it meets all requirements:

scripts/package_skill.py <path/to/skill-folder>

Optional output directory specification:

scripts/package_skill.py <path/to/skill-folder> ./dist

The packaging script will:

1. Validate the skill automatically, checking:

   • YAML frontmatter format and required fields
   • Skill naming conventions and directory structure
   • Description completeness and quality
   • File organization and resource references

2. Package the skill if validation passes, creating a zip file named after the skill (e.g., my-skill.zip) that includes all files and maintains the proper directory structure for distribution.

If validation fails, the script will report the errors and exit without creating a package. Fix any validation errors and run the packaging command again.

Step 6: Iterate

After testing the skill, users may request improvements. Often this happens right after using the skill, with fresh context of how the skill performed.

Iteration workflow:

1. Use the skill on real tasks
2. Notice struggles or inefficiencies
3. Identify how SKILL.md or bundled resources should be updated
4. Implement changes and test again

Skill Repair & Maintenance

When Skills Break

Skills can fail to load due to various issues. Common symptoms include:

• "Unknown skill" errors when trying to activate a skill
• Missing registry entries in skills.json
• Invalid metadata format in SKILL.md frontmatter
• Structural problems with missing directories or files

Automated Skill Repair

Use the built-in repair functionality to automatically diagnose and fix common issues:

# Repair a specific skill
scripts/repair_skill.py <skill-name>

# Diagnose without repairing
scripts/repair_skill.py --diagnose <skill-name>

# List all skills with issues
scripts/repair_skill.py --list-issues

Common Repair Scenarios

Scenario 1: Skill Not Found in Registry

Problem: "Error: Unknown skill: my-skill-name" Solution: The repair script automatically adds missing skills to the skills.json registry with proper metadata extracted from SKILL.md.

Scenario 2: Invalid Frontmatter Format

Problem: YAML parsing errors or missing required fields Solution: The repair script fixes frontmatter format, adds missing required fields (name, description), and ensures proper YAML structure.

Scenario 3: Missing Skill Structure

Problem: Missing SKILL.md or required directories Solution: The repair script identifies structural issues and provides guidance for fixing them.

Scenario 4: Category Not Defined

Problem: Skill references undefined category in registry Solution: The repair script adds missing category definitions to skills.json.

Manual Registry Fixes

For advanced users, skills.json can be manually edited:

{
  "skills": {
    "my-skill": {
      "name": "My Skill Display Name",
      "category": "create",
      "triggers": ["using my skill", "activate my skill"],
      "keywords": ["my", "skill", "automation"],
      "activation_count": 0,
      "last_used": null,
      "related_skills": ["skill-creator-doctor"],
      "description": "Skill description for discovery"
    }
  },
  "categories": {
    "create": {
      "description": "Skills for building new components and features",
      "color": "#45B7D1"
    }
  }
}

Skill Health Monitoring

Regular maintenance ensures skills remain functional:

# Validate a single skill
python scripts/quick_validate.py <path/to/skill>

# Comprehensive system health check
scripts/repair_skill.py --list-issues

Prevention Best Practices

1. Always validate skills after creation with the packaging script
2. Test skill loading immediately after creation or modification
3. Use consistent naming between directory names and registry entries
4. Maintain proper YAML format in SKILL.md frontmatter
5. Update registry entries when modifying skill metadata

Real-World Example: ts-foundation-restorer

The ts-foundation-restorer skill was successfully repaired using this system:

Issue: Skill existed in filesystem but wasn't discoverable Root Cause: Missing registry entry in skills.json Solution: Added proper registry entry with metadata extracted from SKILL.md Result: Skill became discoverable and functional

This demonstrates how the repair system can quickly resolve skill loading failures without manual intervention.

Advanced Troubleshooting Guide

Understanding Claude Code Skill Discovery

Claude Code uses a declarative, prompt-based system for skill discovery. The system scans skills from multiple locations and loads metadata into the system prompt. Claude decides when to invoke skills based on textual descriptions—there's no algorithmic matching at the code level.

Critical YAML Frontmatter Requirements

The most common cause of "Unknown skill" errors is YAML frontmatter validation failures.

Required Fields:

• name: Must use lowercase letters, numbers, and hyphens only (kebab-case), max 64 characters
• description: Brief description (max 1024 characters)

Correct Format:

---
name: my-skill-name
description: Brief description of what the skill does and when to use it
---

Common Validation Failures:

❌ Title Case: name: My Skill Name ❌ snake_case: name: my_skill_name ❌ camelCase: name: mySkillName ❌ Underscores: name: my_skill_name ❌ XML tags: <name>my-skill</name> ❌ Reserved words: Names containing "anthropic", "claude"

Systematic Troubleshooting Process

1. Validate YAML Frontmatter Format

Check for common issues:

# View the frontmatter
cat .claude/skills/my-skill/SKILL.md | head -n 15

# Common issues to look for:
# - Missing opening or closing ---
# - Tabs instead of spaces (use spaces only)
# - Unquoted strings with special characters
# - Extra spaces or hidden characters

2. Check for Hidden Characters and Encoding

Even if YAML looks correct, hidden characters can cause parsing failures:

# Check for hidden characters
cat -A .claude/skills/my-skill/SKILL.md | head -n 15

# Verify UTF-8 encoding
file .claude/skills/my-skill/SKILL.md

3. Verify File Structure

Ensure the directory structure is correct:

.claude/skills/my-skill/
└── SKILL.md  (required, exact capitalization)

The file must be named SKILL.md (all caps).

4. Clear Claude Code Cache

Claude Code maintains caches that may not refresh after skill modifications:

# Option 1: Use /clear command (may not fully clear skill cache)
# In Claude Code session, type:
/clear

# Option 2: Completely restart Claude Code (recommended)
# Exit current session and restart:
claude

For persistent cache issues:

• Quit Claude Code completely
• Clear cache directories (if they exist):
  • macOS: ~/Library/Caches/Claude/
  • Clear any residual temp files
• Restart Claude Code

5. Test with Minimal Skill

Create a test skill to isolate the issue:

mkdir -p .claude/skills/test-skill
cat > .claude/skills/test-skill/SKILL.md << 'EOF'
---
name: test-skill
description: Simple test skill for validation
---

# Test Skill

This is a test skill.
EOF

Restart Claude Code and test if the minimal skill works.

Known Issues and Limitations

1. SDK vs CLI Behavior

Skills may not load correctly when using the Claude Agent SDK compared to the standalone CLI. If you're using the SDK, this is a known issue where skills are not auto-discovered despite correct configuration.

2. Skill System Cache Inconsistencies

• The /clear command may not fully clear skill-related caches
• Skills added or modified during a session may require a complete restart to be recognized
• Some users report skills only load after exiting and restarting Claude Code entirely

3. Frontmatter Parser Strictness

The frontmatter parser is extremely strict and may reject files that appear valid. The parser specifically checks for:

• Exact YAML syntax (no tabs, proper spacing)
• Kebab-case naming convention
• Absence of reserved words
• No XML tags or special characters in metadata

Advanced Debugging Techniques

1. Compare Working vs Broken Skills

Since some skills work correctly, compare their frontmatter format exactly:

# View working skill
cat .claude/skills/working-skill/SKILL.md | head -n 15

# View broken skill
cat .claude/skills/broken-skill/SKILL.md | head -n 15

# Look for differences in:
# - Spacing (tabs vs spaces)
# - Line endings (CRLF vs LF)
# - Character encoding
# - YAML structure

2. Check Claude Code Logs

View logs to see specific skill loading errors:

• macOS: ~/Library/Logs/Claude/
• Linux: Check terminal output with --verbose flag
• Look for parsing errors or skill validation failures

Recommended Solution Path

Based on troubleshooting experience, follow these steps in order:

1. Recreate the SKILL.md file with guaranteed-clean formatting:

   • Copy the content to a new file
   • Ensure name uses only lowercase letters, numbers, and hyphens
   • Use spaces (not tabs) for indentation
   • Save with UTF-8 encoding, Unix line endings (LF)

2. Verify the exact name format:

   ---
   name: my-skill-name
   description: Your description here
   ---
   

3. Completely restart Claude Code:

   • Exit the current session
   • Close all terminal windows
   • Start fresh with claude

4. Test skill recognition:

   • Ask: "List all available Skills"
   • Check if your skill appears

5. If still failing, try renaming the skill:

   • Change to something simpler: my-skill or skill-fix
   • Sometimes shorter names work better

Why Some Skills Work and Others Don't

The inconsistency you're experiencing (some skills load, others don't with identical formats) suggests:

1. Subtle formatting differences invisible to the eye (tabs vs spaces, line endings)
2. Character encoding issues in the specific file
3. Cache corruption for that particular skill
4. Name validation edge case

The fact that renaming doesn't help suggests the issue is likely in the file content itself (encoding, hidden characters, or YAML structure) rather than the name.

Project Analysis & Tech Stack Detection

Before making decisions about skills, analyze your actual project state to understand which skills are relevant.

Detect Project Type & Tech Stack

Objective: Build accurate understanding of your actual project.

Process:

# Find all dependency files
find . -name "package.json" -o -name "requirements.txt" -o -name "pom.xml" \
  -o -name "go.mod" -o -name "Cargo.toml" -o -name "composer.json" \
  -o -name "Gemfile" -o -name "build.gradle"

# Extract technologies (for Node.js)
if [ -f "package.json" ]; then
  echo "Node.js project detected"
  cat package.json | jq -r '.dependencies, .devDependencies | keys[]' | head -20
fi

# Analyze directory structure
echo "=== Project Structure Analysis ==="
for dir in src lib app components services docs k8s docker; do
  if [ -d "$dir" ]; then
    file_count=$(find "$dir" -type f | wc -l)
    echo "$dir/ - $file_count files"
  fi
done

Output Format:

{
  "system_reality": {
    "project_type": "Vue.js TypeScript Application",
    "primary_technologies": ["Vue 3", "TypeScript", "Vite", "Pinia"],
    "frameworks": ["Vue.js", "Tailwind CSS"],
    "build_tools": ["Vite", "ESLint", "TypeScript"]
  },
  "relevance_domains": ["frontend", "vue.js", "typescript", "pinia", "productivity"]
}

Necessity Scoring Algorithm

Objective: Rank skills by importance and relevance to current project (0-100 scale).

def calculate_necessity_score(skill_data, project_reality, usage_stats):
    """Calculate necessity score for a skill (0-100)"""
    score = 0

    # Base score from recent usage (40 points max)
    usage = usage_stats.get(skill_data['name'], {})
    recent_uses = usage.get('uses_90_days', 0)
    usage_score = min(recent_uses * 2, 40)  # 2 points per use, max 40
    score += usage_score

    # Project relevance score (30 points max)
    skill_domains = extract_domains(skill_data['description'], skill_data['capabilities'])
    project_domains = project_reality.get('relevance_domains', [])
    domain_overlap = len(set(skill_domains) & set(project_domains))
    relevance_score = min(domain_overlap * 10, 30)  # 10 points per matching domain
    score += relevance_score

    # Category importance score (20 points max)
    important_categories = ['debug', 'create', 'fix']
    if skill_data['category'] in important_categories:
        score += 20
    elif skill_data['category'] in ['optimize', 'analyze']:
        score += 15
    else:
        score += 10

    # Dependency score (10 points max)
    if skill_data['name'] in usage_stats.get('dependencies', {}):
        dependent_count = len(usage_stats['dependencies'][skill_data['name']])
        dependency_score = min(dependent_count * 2, 10)
        score += dependency_score

    return min(score, 100)

Score Interpretation:

• 80-100: Critical skill, actively used, high project relevance
• 60-79: Important skill, moderate usage
• 40-59: Useful but not essential
• 20-39: Low priority, candidate for review
• 0-19: Archive candidate

Skill Consolidation & Optimization

Manage growing skill collections by identifying duplicates, resolving conflicts, merging similar skills, and archiving obsolete skills. This ensures your skill ecosystem remains efficient, maintainable, and free of redundancy.

When to Use

• Managing growing skill collections (10+ skills)
• Suspecting duplicate/overlapping skills with similar purposes
• Changing technology stacks (e.g., migrating from MongoDB to PostgreSQL)
• Removing deprecated features or outdated workflows
• Similar names/triggers/keywords causing activation confusion
• Wanting to optimize the skill ecosystem for better organization

Core Workflows

Workflow 1: Scan & Inventory

Build comprehensive inventory of all skills with usage statistics and metadata.

# Generate skill inventory
python scripts/scan_skills.py --output skill_inventory.json

What it does:

• Scans all skills in skills/ directory
• Extracts metadata: name, description, category, triggers, keywords
• Reads usage stats from config/skills.json
• Analyzes bundled resources: scripts, references, assets
• Outputs structured JSON with summary statistics

Output includes:

• Skill metadata and purpose
• Activation counts and last used dates
• Resource analysis (scripts, references, assets)
• Category distribution
• Usage patterns and trends

Workflow 2: Analyze Similarity

Identify merge candidates, trigger conflicts, and obsolete skills.

# Analyze for consolidation opportunities
python scripts/analyze_similarity.py --inventory skill_inventory.json --threshold 0.65

# Custom threshold
python scripts/analyze_similarity.py --inventory skill_inventory.json --threshold 0.80

Similarity Detection Methods:

1. Keyword/Trigger Overlap (Jaccard Similarity)

   • J(A,B) = |A ∩ B| / |A ∪ B|
   • Identifies skills with shared triggers (conflicts)
   • Detects >50% trigger overlap

2. Content Similarity

   • Compares skill descriptions and metadata
   • Analyzes semantic similarity
   • Identifies complementary workflows

3. Category Matching

   • Skills in same category have higher consolidation likelihood
   • Groups related domain-specific skills

4. Usage Statistics

   • Identifies unused skills (activation_count = 0)
   • Finds outdated skills (last_used > 6 months)
   • Prioritizes based on usage patterns

Outputs:

• skill_consolidation_report.md (human-readable recommendations)
• skill_analysis.json (detailed analysis data)
• Priority categorization: High (>80%), Medium (65-80%), Review (<65%)

Workflow 3: Review Consolidation Report

Analyze the generated report and make informed decisions.

# Open the generated report
cat skill_consolidation_report.md

# Key sections to review:
# - High Priority Merge Candidates (>80% similarity)
# - Trigger Conflicts (ambiguous activations)
# - Obsolete Skills (unused or outdated)
# - Medium Priority Candidates (65-80% similarity)

Decision Criteria:

Merge When:

• 80%+ similarity with overlapping functionality
• Trigger conflicts causing ambiguous activation
• Complementary workflows in same domain
• One skill rarely used, fits naturally in another

Archive When:

• Never used (activation_count = 0)
• Not used in 6+ months
• Tech stack changed (old technology references)
• Features removed from project

Workflow 4: Execute Skill Merges

Safely merge similar skills while preserving functionality.

Natural Language Commands:

"Merge task-creator and task-manager based on the consolidation report"
"Combine these duplicate Vue debugging skills"
"Merge skill-a into skill-b, keep skill-b as primary"

Merge Process:

1. Analyze both skills - Read SKILL.md files completely
2. Identify unique content - Find different/valuable content in each
3. Create unified SKILL.md - Preserve all unique functionality
4. Combine metadata - Merge triggers, keywords, related_skills
5. Copy bundled resources - Move scripts/references/assets to primary skill
6. Update registry - Modify config/skills.json with merged metadata
7. Archive secondary skill - Move to skills/archive/ with documentation
8. Validate merged skill - Ensure it loads and functions correctly
9. Report completion - List merged triggers/keywords and changes

Registry Updates:

{
  "merged_from": ["task-creator", "task-editor"],
  "activation_count": 37,  // Sum of both skills
  "triggers": ["create task", "edit task", "manage tasks", "task operations"],
  "last_used": "2025-11-13"  // Most recent date
}

Workflow 5: Archive/Remove Obsolete Skills

Clean up unused or outdated skills safely.

Natural Language Commands:

"Archive old-mongodb-helper skill, we migrated to PostgreSQL"
"Remove unused-experimental-skill, it was never activated"
"Archive all skills related to deprecated feature X"

Archive Process:

1. Create archive directory - skills/archive/[skill-name]archived[date]/
2. Move skill - Relocate entire skill directory
3. Create ARCHIVED.md - Document reason, date, and restoration instructions
4. Update registry - Remove skill entry from config/skills.json
5. Update references - Remove from related_skills in other skills
6. Update archive index - Add to skills/archive/ARCHIVE_INDEX.md

ARCHIVED.md Template:

# Archived: [skill-name]

**Archive Date:** 2025-11-13
**Reason:** [Archive reason]
**Original Description:** [Skill description]

## Archive Reason
[Detailed explanation of why skill was archived]

## Restoration Instructions
To restore this skill:
1. Move directory from `archive/` back to `skills/`
2. Add entry to `config/skills.json`
3. Update any related_skills references
4. Test skill loading

## Related Skills
[List of skills that referenced this skill]

Natural Language Interface

Use consolidation features through natural conversation:

Analysis Commands:

• "Scan my skills and find duplicates"
• "Analyze my skills for consolidation opportunities"
• "Find skills I haven't used in 6 months"
• "Check for trigger conflicts in my skills"
• "What consolidation opportunities do I have?"

Action Commands:

• "Merge [skill-a] and [skill-b]"
• "Archive [old-skill] because [reason]"
• "Combine these Vue debugging skills"
• "We migrated from MongoDB to PostgreSQL, clean up old skills"
• "Fix the trigger conflicts for 'create task'"

Examples

Example 1: Duplicate Skills

User: "I created task-creator and later task-manager. Are they duplicates?"

Claude analyzes:
- task-creator: "Create new tasks" (triggers: ["create task", "new task"], activations: 25)
- task-manager: "Create, edit, delete tasks" (triggers: ["manage tasks", "create task"], activations: 12)

Finding: 87% similar (overlapping triggers, similar purpose)

Recommendation: Merge into task-manager (more used, broader scope)

Execution:
- Merges both skills into task-manager
- Archives task-creator
- Updates registry with merged_from field
- Reports completion with consolidated triggers

Example 2: Tech Stack Migration

User: "We migrated from MongoDB to PostgreSQL. Which skills should I clean up?"

Claude:
- Scans all skills
- Finds: mongodb-helper, mongo-query-builder, mongodb-schema
- Recommends: Archive all three, update database-helper to focus on PostgreSQL

Execution:
- Archives MongoDB skills with proper documentation
- Updates database-helper with PostgreSQL-specific content
- Removes MongoDB skills from registry
- Updates related_skills references

Example 3: Trigger Conflicts

User: "Check for trigger conflicts"

Claude finds:
- "create task" used by: task-creator, task-manager, project-tasks

Recommendation:
- task-creator: Change to "create new task", "add task"
- task-manager: Keep "manage tasks", "organize tasks"
- project-tasks: Change to "create project task", "add to project"

Execution:
- Updates triggers in each skill's registry entry
- Validates no conflicts remain
- Reports updated trigger mappings

Best Practices

Naming Consolidated Skills

• Use broader names: task-creator + task-editor → task-manager
• Use domain + action pattern: [domain]-[action]
• Avoid vague names: "helper", "utils"
• Keep names under 64 characters with kebab-case

Maintenance Schedule

• Monthly (5 minutes): Quick scan for obvious duplicates
• Quarterly (30-60 minutes): Full analysis and consolidation
• After major changes: Tech stack migration, feature removal

Quality Assurance

• Always test merged skills before archiving originals
• Keep archive documentation thorough
• Validate registry consistency after changes
• Test skill loading after major consolidation

Skill Emoji Management

Manage visual identification of skills through custom emoji assignment. Emojis appear during skill activation and execution, providing instant recognition of active skills and better user experience.

When to Use Emoji Management

• Visual Skill Identification: Make skills instantly recognizable during activation
• Category Organization: Use consistent emojis for skill categories (🐛 debug, ⚡ create, 🔧 fix)
• Custom Branding: Assign specific emojis to important or frequently used skills
• Folder Organization: Align folder names with registry emoji assignments
• Team Consistency: Standardize emoji usage across team skill collections
