Skill

Skill Management CLI

Meta-skill for managing oh-my-claudecode skills via CLI-like commands.

Subcommands

/skill list

Show all available skills organized by scope.

Behavior:

1. Scan bundled built-in skills in the plugin skills/ directory (read-only)
2. Scan user skills at ~/.claude/skills/omc-learned/
3. Scan project skills at .omc/skills/
4. Parse YAML frontmatter for metadata
5. Display in organized table format:

BUILT-IN SKILLS (bundled with oh-my-claudecode):
| Name              | Description                    | Scope    |
|-------------------|--------------------------------|----------|
| visual-verdict    | Structured visual QA verdicts  | built-in |
| ralph             | Persistence loop               | built-in |

USER SKILLS (~/.claude/skills/omc-learned/):
| Name              | Triggers           | Quality | Usage | Scope |
|-------------------|--------------------|---------|-------|-------|
| error-handler     | fix, error         | 95%     | 42    | user  |
| api-builder       | api, endpoint      | 88%     | 23    | user  |

PROJECT SKILLS (.omc/skills/):
| Name              | Triggers           | Quality | Usage | Scope   |
|-------------------|--------------------|---------|-------|---------|
| test-runner       | test, run          | 92%     | 15    | project |

Fallback: If quality/usage stats not available, show "N/A"

Built-in skill note: Built-in skills are bundled with oh-my-claudecode and are discoverable/readable, but not removed or edited through /skill remove or /skill edit.

/skill add [name]

Interactive wizard for creating a new skill.

Behavior:

1. Ask for skill name (if not provided in command)
   • Validate: lowercase, hyphens only, no spaces
2. Ask for description
   • Clear, concise one-liner
3. Ask for triggers (comma-separated keywords)
   • Example: "error, fix, debug"
4. Ask for argument hint (optional)
   • Example: " [options]"
5. Ask for scope:
   • user → ~/.claude/skills/omc-learned/<name>/SKILL.md
   • project → .omc/skills/<name>/SKILL.md
6. Create skill file with template:

---
name: <name>
description: <description>
triggers:
  - <trigger1>
  - <trigger2>
argument-hint: "<args>"
---

# <Name> Skill

## Purpose

[Describe what this skill does]

## When to Activate

[Describe triggers and conditions]

## Workflow

...

/skill setup

Interactive wizard for setting up and managing local skills (formerly local-skills-setup).

Behavior:

Step 1: Directory Check and Setup

First, check if skill directories exist and create them if needed:

# Check and create user-level skills directory
USER_SKILLS_DIR="$HOME/.claude/skills/omc-learned"
if [ -d "$USER_SKILLS_DIR" ]; then
  echo "User skills directory exists: $USER_SKILLS_DIR"
else
  mkdir -p "$USER_SKILLS_DIR"
  echo "Created user skills directory: $USER_SKILLS_DIR"
fi

# Check and create project-level skills directory
PROJECT_SKILLS_DIR=".omc/skills"
if [ -d "$PROJECT_SKILLS_DIR" ]; then
  echo "Project skills directory exists: $PROJECT_SKILLS_DIR"
else
  mkdir -p "$PROJECT_SKILLS_DIR"
  echo "Created project skills directory: $PROJECT_SKILLS_DIR"
fi

Step 2: Skill Scan and Inventory

Scan both directories and show a comprehensive inventory:

# Scan user-level skills
echo "=== USER-LEVEL SKILLS (~/.claude/skills/omc-learned/) ==="
if [ -d "$HOME/.claude/skills/omc-learned" ]; then
  USER_COUNT=$(find "$HOME/.claude/skills/omc-learned" -name "*.md" 2>/dev/null | wc -l)
  echo "Total skills: $USER_COUNT"

  if [ $USER_COUNT -gt 0 ]; then
    echo ""
    echo "Skills found:"
    find "$HOME/.claude/skills/omc-learned" -name "*.md" -type f -exec sh -c '
      FILE="$1"
      NAME=$(grep -m1 "^name:" "$FILE" 2>/dev/null | sed "s/name: //")
      DESC=$(grep -m1 "^description:" "$FILE" 2>/dev/null | sed "s/description: //")
      MODIFIED=$(stat -c "%y" "$FILE" 2>/dev/null || stat -f "%Sm" "$FILE" 2>/dev/null)
      echo "  - $NAME"
      [ -n "$DESC" ] && echo "    Description: $DESC"
      echo "    Modified: $MODIFIED"
      echo ""
    ' sh {} \;
  fi
else
  echo "Directory not found"
fi

echo ""
echo "=== PROJECT-LEVEL SKILLS (.omc/skills/) ==="
if [ -d ".omc/skills" ]; then
  PROJECT_COUNT=$(find ".omc/skills" -name "*.md" 2>/dev/null | wc -l)
  echo "Total skills: $PROJECT_COUNT"

  if [ $PROJECT_COUNT -gt 0 ]; then
    echo ""
    echo "Skills found:"
    find ".omc/skills" -name "*.md" -type f -exec sh -c '
      FILE="$1"
      NAME=$(grep -m1 "^name:" "$FILE" 2>/dev/null | sed "s/name: //")
      DESC=$(grep -m1 "^description:" "$FILE" 2>/dev/null | sed "s/description: //")
      MODIFIED=$(stat -c "%y" "$FILE" 2>/dev/null || stat -f "%Sm" "$FILE" 2>/dev/null)
      echo "  - $NAME"
      [ -n "$DESC" ] && echo "    Description: $DESC"
      echo "    Modified: $MODIFIED"
      echo ""
    ' sh {} \;
  fi
else
  echo "Directory not found"
fi

# Summary
TOTAL=$((USER_COUNT + PROJECT_COUNT))
echo "=== SUMMARY ==="
echo "Total skills across all directories: $TOTAL"

Step 3: Quick Actions Menu

After scanning, use the AskUserQuestion tool to offer these options:

Question: "What would you like to do with your local skills?"

Options:

1. Add new skill - Start the skill creation wizard (invoke /skill add)
2. List all skills with details - Show comprehensive skill inventory (invoke /skill list)
3. Scan conversation for patterns - Analyze current conversation for skill-worthy patterns
4. Import skill - Import a skill from URL or paste content
5. Done - Exit the wizard

Option 3: Scan Conversation for Patterns

Analyze the current conversation context to identify potential skill-worthy patterns. Look for:

• Recent debugging sessions with non-obvious solutions
• Tricky bugs that required investigation
• Codebase-specific workarounds discovered
• Error patterns that took time to resolve

Report findings and ask if user wants to extract any as skills (invoke /learner if yes).

Option 4: Import Skill

Ask user to provide either:

• URL: Download skill from a URL (e.g., GitHub gist)
• Paste content: Paste skill markdown content directly

Then ask for scope:

• User-level (~/.claude/skills/omc-learned/) - Available across all projects
• Project-level (.omc/skills/) - Only for this project

Validate the skill format and save to the chosen location.

/skill scan

Quick command to scan both skill directories (subset of /skill setup).

Behavior: Run the scan from Step 2 of /skill setup without the interactive wizard.

Skill Templates

When creating skills via /skill add or /skill setup, offer quick templates for common skill types:

Error Solution Template

Error Handling

All commands must handle:

• File/directory doesn't exist
• Permission errors
• Invalid YAML frontmatter
• Duplicate skill names
• Invalid skill names (spaces, special chars)

Error format:

✗ Error: <clear message>
→ Suggestion: <helpful next step>

Usage Examples

# List all skills
/skill list

# Create a new skill
/skill add my-custom-skill

# Remove a skill
/skill remove old-skill

# Edit existing skill
/skill edit error-handler

# Search for skills
/skill search typescript error

# Get detailed info
/skill info my-custom-skill

# Sync between scopes
/skill sync

# Run setup wizard
/skill setup

# Quick scan
/skill scan

Usage Modes

Direct Command Mode

When invoked with an argument, skip the interactive wizard:

• /oh-my-claudecode:skill list - Show detailed skill inventory
• /oh-my-claudecode:skill add - Start skill creation (invoke learner)
• /oh-my-claudecode:skill scan - Scan both skill directories

Interactive Mode

When invoked without arguments, run the full guided wizard.

Benefits of Local Skills

Automatic Application: Claude detects triggers and applies skills automatically - no need to remember or search for solutions.

Version Control: Project-level skills (.omc/skills/) are committed with your code, so the whole team benefits.

Evolving Knowledge: Skills improve over time as you discover better approaches and refine triggers.

Reduced Token Usage: Instead of re-solving the same problems, Claude applies known patterns efficiently.

Codebase Memory: Preserves institutional knowledge that would otherwise be lost in conversation history.

Skill Quality Guidelines

Good skills are:

1. Non-Googleable - Can't easily find via search

   • BAD: "How to read files in TypeScript"
   • GOOD: "This codebase uses custom path resolution requiring fileURLToPath"

2. Context-Specific - References actual files/errors from THIS codebase

   • BAD: "Use try/catch for error handling"
   • GOOD: "The aiohttp proxy in server.py:42 crashes on ClientDisconnectedError"

3. Actionable with Precision - Tells exactly WHAT to do and WHERE

   • BAD: "Handle edge cases"
   • GOOD: "When seeing 'Cannot find module' in dist/, check tsconfig.json moduleResolution"

4. Hard-Won - Required significant debugging effort

   • BAD: Generic programming patterns
   • GOOD: "Race condition in worker.ts - Promise.all at line 89 needs await"

Related Skills

• /oh-my-claudecode:learner - Extract a skill from current conversation
• /oh-my-claudecode:note - Save quick notes (less formal than skills)
• /oh-my-claudecode:deepinit - Generate AGENTS.md codebase hierarchy

Tips for Users

• Run /oh-my-claudecode:skill list periodically to review your skill library
• After solving a tricky bug, immediately run learner to capture it
• Use project-level skills for codebase-specific knowledge
• Use user-level skills for general patterns that apply everywhere
• Review and refine triggers over time to improve matching accuracy

Implementation Notes

1. YAML Parsing: Use frontmatter extraction for metadata
2. File Operations: Use Read/Write tools, never Edit for new files
3. User Confirmation: Always confirm destructive operations
4. Clear Feedback: Use checkmarks (✓), crosses (✗), arrows (→) for clarity
5. Scope Resolution: Always check both user and project scopes
6. Validation: Enforce naming conventions (lowercase, hyphens only)
